    摘要: A brush holding device of an "easy-to-assemble" type disposed between a yoke and an end frame of a motor. The device has a brush holder formed in one body from an electrically insulating material to include an annular-type field winding fixing frame, a brush holding stay having a plurality of brush chambers thereon, each of the brush chambers having at least an opening on the side of the end frame, integral connecting portions annularly connecting the spaced brush chambers therebetween, an insulating plate member having relatively rigid body portions to cover the openings of the brush chambers and relatively flexible portions connecting the body portions therebetween, and means for fixing the insulation to the brush holders by deforming the flexible portions of the insulator toward the brush holders. The aforementioned annular fixing frame has a plurality of flanges radially outwardly extending from the outer periphery thereof by which the annular frame is circumferentially axially aligned with the yoke. Consequently, the brush holding device is able to be rigidly held between the yoke and the end frame without using a bolt while establishing a good alignment of the device in the circumferential and the axial direction.

    摘要: A starter for an engine, having a ring gear includes an output shaft for slidably holding a pinion gear engageable with the ring gear, a housing having an opening portion that enables the pinion gear to engage with the ring gear when the pinion gear advances, a cover having a shutter, a front wall and a side wall for sliding together with the pinion gear. The shutter opens the opening portion when the pinion gear advances and shuts the most part of the opening portion when the pinion gear retracts. The front wall is provided to cover at least half of a front portion, which faces to the ring gear, of the pinion gear. The side wall is extended from the front wall in a direction parallel to an axis of the output shaft to cover at least half of the gear tooth periphery in a circumferential direction of the pinion gear. When water carried by the rotating ring gear comes to the opening portion when the pinion gear rotates with the ring gear, most of such water is blocked by the gear tooth. Furthermore, the rest of water is blocked by small gaps between the pinion gear and the cover. When the pinion gear is disengaged from the ring gear, the shutter closes most of the opening portion. Therefore, most of water carried by the rotating gear is blocked by the shutter. Even if water enters inside of the housing through a small gap between the opening portion and the shutter, water is blocked by small gaps between the pinion gear and the cover.

    摘要: A resilient restricting member of a rotation restricting member which restricts a pinion moving body from rotating is accommodated in a frame of a restricting member holder under a flexed and loaded state so that the rotation restricting member has a sufficient rotation-restricting function as long as the rotary force of the pinion moving body does not exceed the load acting thereon at the time of engagement and restriction of rotation. When a pinion gear abuts the end face of a ring gear and the pinion moving body is restricted from moving forward, the entire rotary force of an output shaft acts on the pinion moving body. The resilient restricting member flexes further in the restricting member holder to allow rotation of the pinion moving body, thus enabling the pinion gear to mesh the ring gear. Thus, the rotary force of the output shaft is converted to the advancing force of the pinion moving body surely even when the spiraling of the helical spline is not so large.

    摘要: An electric rotating machine has an armature coil comprising outer and inner coil trunks disposed in slots of an armature core as well as outer and inner coil arms disposed along an axial side surface of the armature core. The outer coil arms are arranged to operate as a commutator and in slidable contact with brushes. The diameters of the radially outermost parts of the outer coil arms and the brushes are larger than that of the radially outermost surface of the outer conductor. This arrangement assures a larger commutator-brush contact area that reduces current density as well as heat generation in the commutator-brush contact area. As the radially outwardly extending parts of the outer coil arms are exposed to the surrounding air, the outer coil trunk, the outer coil arm and the brushes as well as the radially outwardly extending part are cooled effectively during rotation of the armature core.

    摘要: An overrunning clutch that can absorb the impact torque, and accurately and easily conveys the maximum torque. A clutch outer tubular portion and inner tubular portion are separately fixed on an internal gear and a center case of an epicycle gear reduction mechanism. A wedge-shaped groove is formed on one of an inner circumference of the outer tubular portion and an outer circumference of the inner tubular portion to accomodate a rolling element. A fitting concave portion to fit the rolling element is formed on the other one of the inner circumference of the outer tubular portion and the outer circumference of the inner tubular portion. With this, the torque value generated when the rolling element leaves the fitting concave portion can be accurately set just by setting the depth of the fitting concave portion. The radial force that acts on the opposite direction of the tubular portions holding the rolling element can be reduced. This allows the strength of the tubular portions to be reduced, and the weight to be lightened. As the torque is not conveyed with frictional force, the wear is also reduced.
