摘要： PURPOSE: To provide a starter which can reduce axial torque loss encountered in a rear bearing. CONSTITUTION: The magnetic center of the field of a motor 500 is shifted from the magnetic center of its armature 540 in the direction opposite to the direction of the pressing force of the brush 910. Then the length in the axial direction between the magnetic center of the motor 500 field and that of the armature 540 is taken as L1. The length in the axial direction comprising a bearing holding member 900 containing a bearing 564 that supports the armature shaft 510 on the brush 910 side; and a commutator contact member that is opposed to the bearing holding member 900 and is in contact with the commutator of the armature 540, is taken as L2. L1 and L2 are set to almost the same value.

摘要： PURPOSE:To prevent water from being sucked into a motor chamber and a switch chamber and also rain water from entering them without providing any water draining undercover. CONSTITUTION:A motor chamber A is communicated with a starter outer part through a long ventilating route comprising a motor chamber ventilating hole B, a wall recessed space F, a communicating hole, a wall recessed space F, a communicating hole, a clutch chamber E, and a bent ventilating hole G. Also a switch chamber C is communicated with the starter outer part through a long ventilating route comprising a switch chamber ventilating hole D, the clutch chamber E, and the bent ventilating hole G. Thus any water is not sucked into the motor chamber A and switch chamber C by negative pressures in the motor chamber A and switch chamber C, and also rain water is prevented from entering them.

CONSTITUTION:A plurality of commutator segments 161, 162-16n formed by integrating sector-shaped segment body 17 and a flat platelike holding member 18 are arranged at an equal internal on its circumference. Commutator segment group is disposed outside a bush 14 fixed to a shaft 12 through a knurled part 13. A window hole 191 is opened at the flat plate of the holding member 18. Inorganic material 20 such as silica alumina, etc.,m is filled between the bush 14 and the commutator segment group, between the commutator segments and in the window hole 191, baked and solidified. Thus, a commutator durable against a high speed rotation is manufactured.

摘要： PURPOSE:To increase the space factor of a field coil, by a method where in a cross angle between the tubular section of a coil bobbin, made of resin, and the abutting part of an outside reel frame against the inner peripheral surface of a tublar yoke is determined so as to correspond to the cross angle between a field iron core and the inner peripheral surface of the yoke. CONSTITUTION:A coil bobbin 4 is provided with: a tubular section 41 for winding a field coil 5; an inside reeling frame 42, provided at the fore end of the tubular section 41, an outside reeling frame 43, provided behind the tubular section 41, and insulating papers 44, 45 for insulating the inside reeling frame 42 from the magnetic pole piece 33 of a field magnetic pole 3. In this case, the coil bobbin 4 is formed so that the slant angle of the inner peripheral surface 41a of the tubular section 41 becomes theta at the lengthwise parts 41b, 41c. The angle theta is determined in accordance with a radius of curvature obtained by the inner periphery of the yoke 2, the width of the field magnet iron core 32 and the height of the field coil 5, which is the length between the yoke side end of the field coil 5 and the magnetic pole piece side end of the same.

摘要： PURPOSE:To maintain the sealability between a switch cover and a switch housing even when the switch housing is compact, by providing a bush and a seal member between the switch cover and the switch housing. CONSTITUTION:A seal member 19 has a shape to be fitted on a disc portion 16a of a switch cover 16, and when it is fitted on the disc portion 16a, a bush 18 is covered with a part of the seal member 19. The switch cover 16 is firmly fixed through the seal member 19 to a stationary core 8 by fastening a bolt 20 with a nut 21. Even when the switch cover 16 is larger than a switch housing 2, the seal member 19 is reliably urged by an end surface of the cover 16 and an end surface of the bush 18 by covering longitudinal opposite ends of a recess 16b of the cover 16 with the bushes 18, thus maintaining the sealability.

摘要： PURPOSE:To assemble a clutch cover without a restriction on pinion diameter by engaging a collar portion of a clutch cover with the end surface of a clutch outer at the opposite side to a pinion. CONSTITUTION:A helical spline 1a of a spline tube 1 is engaged with a shaft of a starter motor, and a cylindrical clutch outer 2 integrally formed with the tube 1 has a cam face on the inner periphery thereof. A clutch inner 3 confronts with the cam face 2a of the clutch outer 2. A sleeve portion 9a and a collar portion 9b pressed to the outer periphery of the clutch outer 2 are formed on a clutch cover 9. The sleeve portion 9a is brought into contact with the other end surface 2c of the clutch outer 2 and the other end portion 9b is fastened round a half member 7 extending from the outer periphery to the end portion to connect the clutch outer 2 and the inner 3 to each other. The reference numeral 4 designates a pinion.

摘要： PURPOSE:To prevent the early-stage wear of a bush provided on a housing and obtain a light-weight starter by removably supporting the outer periphery of a clutch outer on said housing via a housing bush. CONSTITUTION:The outer periphery of a clutch outer 1 is removably supported by a housing bush 2 which is press-fittedly fixed to a housing 3. Accordingly, when an engine is started and even if a pinion 5 is overly rotated at a high speed by a ring gear 9, the rotation is not transmitted to the clutch outer 1 due to the inner 4 and the roller 6 of an overrunning clutch. Thereby, the rotation of the clutch outer 1 is a low speed rotation at about the same speed as the non-load rotation of a motor, without causing wear due to a high speed rotation. Also, by removably supporting a clutch outer 1, the dimension from a housing installing surface can be reduced, enabling a device to be lightened by that amount.
