Abstract: A dust cover to cover an opening of a housing through which at least one of a shaft and a pipe extends includes a hole-edge portion and a main body. The at least one of the shaft and the pipe is extendable through the through hole. The hole-edge portion defines an edge of a through hole through which the at least one of the shaft and the pipe is extendable. The main body is configured to cover the opening. The main body has a hardness different from a hardness of the hole-edge portion.

Abstract: A clutch is configured to mechanically establish and disestablish a torque transmission path between an input shaft through which a torque is input and an output shaft through which the torque is output. The clutch includes a sun gear, an internal gear, planetary gears, and a carrier. The sun gear is configured to switch between a fixed state and a non-fixed state. The internal gear is coupled to the input shaft in a torque transmittable manner. The planetary gears are configured to mesh with the sun gear and the internal gear. The carrier is coupled to the output shaft in a torque transmittable manner and configured to support the planetary gears rotatably. The carrier includes a coupling portion to be coupled to a detachment member configured to detach the carrier from the clutch.

Abstract: A steering device includes a clutch and a wheel-turning shaft. The clutch includes an input shaft, an output shaft, a planetary gear mechanism, a housing, and a restriction member. The planetary gear mechanism is coupled to each of the input shaft and the output shaft. The housing is configured to accommodate the planetary gear mechanism and at least part of the output shaft. The restriction member is secured to the housing or constitutes part of the housing. The restriction member is opposed to an outer surface of the output shaft through a gap so as to restrict inclination of the output shaft. The wheel-turning shaft is configured to be displaced in accordance with rotation of the output shaft so as to turn wheels of a vehicle.

Abstract: A motive power transmission mechanism includes a motor, a drive pulley, a driven pulley, a belt, a housing, and a cap. The motor includes an output shaft and a motor main body. The drive pulley is configured to rotate together with the output shaft. The belt is wound across the drive pulley and the driven pulley to transmit torque from the drive pulley to the driven pulley. The housing accommodates the drive pulley, the belt, and the driven pulley. The housing includes a work window which faces the belt and through which the belt undergoes work from outside of the housing. The cap is configured to close the work window when the work is not performed. The cap includes a porous portion having air-permeability and water-impermeability.

Abstract: A clutch includes a sun gear, an internal gear, planetary gears, a carrier, a first area, a second area, and a third area. The carrier has a through hole through which an output shaft extends. The first area is disposed on an inner wall of the carrier defining the through hole. The second area is disposed on an outer surface of the output shaft and is spline-fitted to the first area. The third area is disposed at a position that is on the outer surface of the output shaft and that is closer to the input shaft than the second area is to the input shaft. The third area has a shape that makes the third area rotatable while being fitted to the first area.
