摘要： PURPOSE:To miniaturize the starter by reducing an axial distance between a starter motor and an overrunning clutch. CONSTITUTION:The pinion shifter 50 for the starter is set up between the clutch 20 and a magnet switch 30. The pinion shifter has a drive lever 51 and a drive spring 52. The drive spring 52 is wound on the pin 51d of the drive lever 51, and the one end 52a of the drive spring is bent and inserted into the hole of a fulcrum 51b of the drive lever 51. When the magnet switch 30 is conducted, an end section 52b is pulled by a hook 32 to rock the drive lever 51, and a pinion shaft 41 is moved to the left to connect the pinion 22 to the ring gear of an engine. The motor 10 is conducted at the same time, and the revolving torque of the motor 10 is transmitted to the engine. The switch 30 can be adjoined to the motor 10 because the end section 52b is folded back.

摘要： PURPOSE: To provide a starter that is able to shorten the extent of axial length and consequent miniaturization particularly so far. CONSTITUTION: A solenoid switch 1 of a starter is clamped to a bracket 17 is a position archwise extending in and around a starter output shaft almost in the circumferential direction with this starter output shaft as the center, and a plunger 3 turns round almost in the circumferential direction with the starter output shaft as the center, thereby opening or closing a motor current controlling contact. Therefore, in making the starter output shaft a reference, in both radial and axial directions, dimensions necessary for storage of the solenoid switch 1 are reducible, so miniaturization in the starter is thus made achievable.

摘要： PURPOSE:To prevent the temperature rise of a commutator and the lowering of mechanical strength, and moreover to prevent relative displacement between the resin holder of the commutator and a rotary shaft in spite of increase in the number of revolutions of a starter motor. CONSTITUTION:Since the resin holder 80 of a commutator is fixed in a groove part 25 which is cylindrically recessed in a rotary shaft 21, the commutator can be reduced in its diameter as much as the depth of the groove part 25 recessed cylindrically, and the peripheral speed of the commutator 8 can be reduced as much as the above reduction, and centrifugal force acting on the resin holder 80 can therefore be reduced. In addition, the lowering of frictional heat can reduce the temperature rise of the resin holder 80 and the lowering of its mechanical strength. Joining strength between the resin holder 80 and the rotary shaft 21 can be improved, and moreover joining ability between the rotary shaft 21 and the resin holder 80 can be improved.

摘要： PURPOSE:To shorten the axial length of an armature by extending conductors, laid in double layers through slots in the periphery of an armature iron core, separately toward the radial center along the end face of an insulated iron core, and by connecting them to commutator bars. CONSTITUTION:Armature coils 2 comprising lower coils 2a and upper coils 2b are fitted in slots 4 formed in the axial direction in the periphery of an armature core 3. A brush holder 91 for a brush 93 is installed through an insulation board 90 on the internal surface of an end-frame 10. A commutator 8 on the right end of a rotating shaft 20 comprises a commutator holder 81 and commutator bars 82. The brush 93 is pressed with a spring 94. The lower and upper coils 2a, 2b are connected to inside and outside conductors 2A, 2B, on the end surface of the commutator 8 side, and are shifted by 1/2 coil pitch in the opposite directions each other. On the other end of the core 3, the lower coil 2a is connected aslant to the upper coil 2b. Thus, the axial length of the armature core 3 is shortened, contributing to cutting the size and weight, and increasing capacity.

摘要： PURPOSE:To provide a starter having a simple construction with easy manufacture and maintenance and also capable of reducing axial view required area of a device. CONSTITUTION:A direct-acting shaft 51 is actuated in nearly radial direction if an electromagnetic switch 5 disposed adjacent to the rear portion of a motor 2 is electrified to energize the base end of a pinion transfer mechanism 6. Then, the pinion actuating means (arm) 64 of a pinion transfer mechanism 6 disposed axially on an outside of the iron core of the armature of the motor 2 is actuated axially and an one way clutch 4 and a pinion gear 3 are advanced directly by the tip end of a pinion actuating means 64 or through the pinion actuating means 64 and the pinion gear 3 is moshed with a ring gear 30. If electrification to the electromagnetic switch is interrupted, the pinion transfer mechanism 6 and the direct-acting shaft 51 are returned by a return spring 7 and the pinion gear 3 is retreated and the pinion gear 3 is detached from the ring gear 30.

摘要： PURPOSE:To provide a reduction starter for internal combustion engine which is small in size, light in weight, and low in cost by eliminating a clutch, a magnet switch, a lever device, and a lever housing. CONSTITUTION:A drive shaft 4 is extruded forward by an inertia extruding force of a helical spline 4a and an attracting force whereby a plunger 6a is attracted by a solenoid 6, a pinion 7 is meshed with the ring gear 16 to start the internal combustion engine, and the drive shaft 4 is held at that position by the solenoid 6. Also a ratchet 3c transmits only the rotation from a sun gear la, and the rotation from the internal combustion engine is not transmitted because a helical spline 4a is disconnected temporarily between the ratchet 3c and a planetary rotor 3b.

摘要： PURPOSE:To provide a reduction starter for internal combustion engine which is small in size, light in weight, and low in cost by eliminating a clutch, a magnet switch, a lever device, and a housing. CONSTITUTION:A drive shaft 4 is extruded forward by an inertia extruding force of a helical spline 4a, a pinion 7 is meshed with the ring gear 16 of an internal combustion engine to start the internal combustion engine, and the drive shaft 4 is held at that position by a return preventing device 6. When the internal combustion engine is started and the drive shaft 4 is rotated at high speed, a steel ball 6a of the return preventing device 6 comes out of a close-fit hole 3c, and the pinion 7 is disconnected from the ring gear 16. Thus, because the engine rotation is not transmitted, a planetary gear 3, a hollow armature shaft 1, and a motor 10 are prevented from being rotated at excessively high speeds.

摘要： PURPOSE:To prevent seizure at the time of over-running of a clutch in an over- running clutch, which consists of an outer and drive gear unified concentrically, by making a ring bush, which is inserted between the drive gear and a tube, of the oil retentive material, and providing a lightening part in this bush to house the oil retentive member therein. CONSTITUTION:A roller 8 and a ring bush 3 are located between a cylindrical outer 2 having a drive gear 4 concentrically and a tube 5, which is supported by a bearing 10 freely to turn, in the axial direction of the outer 2. A clutch shaft 11 having a pinion 12 in front thereof is inserted into the tube 5 through a helical gear 11a, and the bush 3 has the oil retentive function and a lightening part 3a, and the oil retentive member 6 is housed in this lightening part 3a. Seizure of the bush is thereby prevented to make a clutch compact.
