摘要： A rotatable shaft of a motor main body and a worm shaft of a speed reducing unit are drivingly coupled to each other by a clutch. Surrounding walls, which are arranged radially outward of the clutch to substantially entirely surround the clutch in an imaginary plane that extends substantially perpendicular to the axis of the worm shaft, are formed integrally with a gear housing. Thus, the surrounding walls restrain outward movement of grease, which is applied to predetermined portions of the clutch, so that effluence of the grease from the clutch is restrained.

摘要： A clutch is arranged between a rotatable shaft and a worm shaft in a motor. The clutch includes a driving-side rotator connected to the rotatable shaft, a driven-side rotator connected to the worm shaft, a spring support and a coil spring arranged in the spring support. When the driving-side rotator is rotated upon energization of the motor, the coil spring is wound by the driving-side rotator to reduce an outer diameter of the coil spring, so that the rotation of the driving-side rotator is transmitted to the driven-side rotator and the worm shaft. When the driven-side rotator is rotated by an external mechanical force, the coil spring is unwound by the driven-side rotator to increase the outer diameter of the coil spring, so that a frictional force between the spring support and the coil spring is increased to restrain rotation of the driven-side rotator.

摘要： An electric rotating machine is equipped with a middle core, an outer core disposed outside the middle core which rotates relative to the middle core, and an inner core disposed inside the middle core which rotates relative to the middle core. The middle core comprises plural plates disposed in an axial direction. The plural plates are connected in the axial direction by a connecting member, and joined to a first fixing member. The inner and outer circumferential surfaces are finished in the state where the plates are joined only to the first fixing member, and the opposite side to the first fixing member is joined to a second fixing member after finishing.

摘要： A clutch includes a stopper secured to a gear housing of a motor. Once the stopper is secured to the gear housing, the stopper restrains axial movement of rolling elements by restraining axial movement of a support member, which rotatably supports the rolling elements, to retain the rolling elements within a collar. A driven-side rotator of the clutch includes reinforcing ribs for reinforcing engaging projections of the driven-side rotator.

摘要： A spindle motor preferable for hard disk drive (HDD) is composed of a radial dynamic pressure bearing portion constructed by a periphery of a shaft and a sleeve and a thrust dynamic pressure bearing portion constructed by a thrust plate fixed with the sleeve and the shaft. The dynamic pressure bearing portion is filled with a lubricating oil to help stable rotation of the shaft with a rotor. The spindle motor includes a shaft for having a first taper surface with a taper angle &thgr;1 towards the direction of rotational axis thereof, and a sleeve for having a second taper surface with a taper angle &thgr;2 towards the direction of rotational axis thereof, on the position opposed to the first taper surface. The taper angle &thgr;1 is greater than the taper angle &thgr;2.

摘要： A motor used in a power window system includes a motor section, a warm-gear included output section and a one-way clutch. The one-way clutch is disposed between a motor's shaft and a worm's shaft. The one-way clutch includes a drive member having at least a pair of guide surfaces, driven member coupled with the drive member, a stationary housing, and a rotary member disposed between the driven member and the stationary member and between the pair of guide surfaces. The motor and the one-way clutch has a common member fixed to both the motor and the one-way clutch.
