摘要： A steering device includes a motor; a steering shaft; a belt transmission mechanism including a drive pulley, a driven pulley, and a belt; a housing that accommodates the belt transmission mechanism; and a pulley holder that holds the motor and is attached to the housing so as to rotatably support the drive pulley. The pulley holder includes a first supporting portion that supports a first shaft portion of the drive pulley and a second supporting portion that supports a second shaft portion of the drive pulley. The steering device further includes a pulley holder supporting portion that supports a portion, of the pulley holder, located closer to the second supporting portion than the center of the pulley portion in relation to the housing.

摘要： An actuator includes a motor, a rotation transmitting member, a reverse input preventing device, a converting device, and a rod. The motor includes a rotating shaft. The rotation transmitting member is configured to transmit rotation of the rotating shaft. The reverse input preventing device includes an input member and an output member. The reverse input preventing device is configured to prevent external force input to the output member from being transmitted to the input member. The converting device includes a nut that rotates according to the rotation of the output member. The converting device is configured to convert a rotary motion of the nut into a linear motion. The rod is configured to advance and retract according to the linear motion of the converting device. The input member and the rotation transmitting member are integrated. The output member and the nut are integrated.

摘要： A steering apparatus includes a motor, a rack shaft, a belt transmission mechanism that is provided with a drive pulley connected to the motor, a driven pulley, and a belt wrapped around the drive pulley and the driven pulley, and a converting member that is provided to extend along an axial direction of the rack shaft and that converts a rotational force of the driven pulley into a movement force in the axial direction of the rack shaft. The driven pulley is fastened and fixed to the converting member by a bolt, and the steering apparatus further includes a retaining member that prevents detachment of the bolt by restricting movement of a head of the bolt.
