摘要： PURPOSE: To prevent the increase of the number of parts used in a rotor for rotary electric machine and to reduce the size of the rotor and, at the same time, to simplify the structure of the rotor, to make the rotor to be cooled more easily, and to remove worn particles of a brush from the rotor. CONSTITUTION: An air passage 523a is formed in a rotor core 520 of the holes 523 which are formed by punching core plates 521 piled up upon another to constitute a rotor core 520 and communicated with each other. The passage 523a is formed in such a state that the hole 523a is twisted toward one side in the circumferential direction by laminating the plates 521 in such a state that the plates 521 are turned from each other by a prescribed angle. Since the passage 523a is formed in such a way, an air flow is formed in the passage 523a when the core 520 is rotated and the core 520 can be cooled excellently. In addition, worn particles of a brush can be blown away effectively.

摘要： PURPOSE: To secure the operation of a positive magnet switch that absorbs any impact force at a time when a pinion is meshed with a ring gear. CONSTITUTION: Since a magnet switch 600 is installed somewhere apart more than a pinion 210, a distance between a plunger 610 of this magnet switch 600 and a pinion rotation regulating member 230 is lengthened, thereby making a cording member 680 doubling as a connecting means expansible. Accordingly, any impact force to be produced in time of engagement between the pinion 210 and a ring gear 100 is absorned by this long cording member, whereby it is preventable from being transmitted direct to the plunger 610. Accordingly, there is no vibration is the plunger, and thus any possible separation to be caused between a lower side movable contact 611 and a terminal bolt 620 can be prevented with certainty.

摘要： PURPOSE: To provide a starter that is able to reduce even the extent of axial length while properly maintaining a spring characteristic to press a brush. CONSTITUTION: A compression coil spring 914 is set up in a peripheral side in the radial direction in relation to the axial direction of a plunger 610 of a magnet switch part 600, while spring length of the coil spring 914 is able to utilize as far as a portion of radial length of the magnet switch 600, whereby proper spring stress and load can be set up. Accordingly, service life in the coil spring is sharply improvable. In addition, since the coil spring 914 effectively utilizes a space at a peripheral side of the magnet switch 600, axial length of the coil spring 914 is not added to the axial length of a starter, so that a shortening effect in the whole starter is securable.

摘要： PURPOSE: To provide an overrunning clutch for correctly and easily performing absorption of shock torque, namely, setting of the maximum transmitting torque. CONSTITUTION: The outer cylindrical part 3a and the inner cylindrical part 5a of a one-way clutch are fixed independently from each other on the internal gear and the center case of a planetary gear transmission mechanism respectively, a wedge groove 3 for housing a rolling body 3b in either one of the inner circumferential surface of the outer cylindrical part 3a and the outer circumferential surface of the inner cylindrical part 5a, and a locking recessed part 5e for locking the rolling body 3b in the other one of the inner circumferential surface of the outer cylindrical part 3a and the outer circumferential surface of the inner cylindrical part 5a. By such a way, a torque value given when the rolling body 3b is released from its diameter small recessed part 5e can be surely set by only setting the depth of the locking recessed part 5e. And also since both forces in radial direction locking in respective opposite directions on both cylindrical part 3a and 5a while sandwiching the rolling body 3b are reduced, strengths of both cylindrical parts 3a, 5a can be reduced, and reduction of both weights of cylindrical parts 3a, 5a can be realized. Since torque is not transmitted by frictional force, reduction of abrasion can be realized.

摘要： PURPOSE:To provide a starter having epicyclic reduction mechanism enabling the marked reduction of inertial mass of an epicyclic gear shaft supporter, and the manufacturing method of the starter. CONSTITUTION:An epicyclic gear shaft 82 is formed integrally with an epicyclic gear shaft supporter 81, and the epicyclic gear shaft supporter 81 is fittingly fixed to a drive shaft 4. In this way, the weight of the epicyclic gear shaft supporter 81 can be reduced remarkably, so that the reduction of inertial mass of a drive shaft 84 can be realized, and this can prevent the tooth tip damage of a pinion gear or a ring gear at the remeshed time during the rotation of the pinion gear. The epicyclic gear shaft supporter 81 and the epicyclic gear shaft 82 are formed of metal plates, and the epicyclic gear shaft 82 can be easily manufactured by bending or burring.

摘要： PURPOSE:To cool both a stator coil and a rotor coil excellently by installing a fan having the same number of blades as the number of the pawls of pawl core at the end-surface of the pawl core, and providing an air exhausting hole in the housing of the external surface of a stator core. CONSTITUTION:The cooling fan 21 having the blades 21a is installed at one end surface of a pawl core 19. The number of the blades 21a of the cooling fan 21 is the same as the number of the pawls 19a of the pawl core 19. The angle between the end surface of the pawl core and the blades 21a is so selected as to become the angle other than 90 deg.. The stator coil 15a is arranged at the outer periphery of the cooling fan 21, and the hole 13b for exhausting the cooling air is provided through a housing 13 at the location covering the stator coil 15a. In this constitution, the cooling air which has entered through an air inlet hole 14a cools the rotor coil 20. Then the air is exhausted via the cooling fan 21 and the stator coil 15a. Therefore, the cooling effects for both coils can be enhanced.

摘要： PURPOSE:To enable rapid rotation and increase a generated electricity output, by using a bearing fitted between a field section and a slip ring and another bearing opposed to the former bearing across the field section, to support a pair of frames. CONSTITUTION:The bearings 6, 6' are fitted on bearing mounting portions 3, 3' provided on the pair of frames 1, 1'. A shaft 7 is rotatably supported on the bearings. A field section 8 located inside a stator 5 and a slip ring 9 located at a prescribed distance from the field section are coupled to the shaft. As a result, the frames 1, 1' are located in direct contact with each other and secured on each other and the mounting parts 3, 3' are easily aligned to each other. The bearings 6, 6' are thus prevented from becoming eccentric. According to this constitution, an electricity generator can be rapidly rotated to increase the out of generated electricity output.
