PROBLEM TO BE SOLVED: To provide an electric steering device equipped with a driving pulley which facilitates the processing of a gear section to the driving pulley, surely prevents each regulating member from being mistakenly attached to the pulley main body, keeps the attached state firm between the pulley main body and each regulating member, and is compact. SOLUTION: This electric steering device is equipped with a steering member which reciprocates in response to a steering wheel operation, a ball nut which is fitted on a ball threaded shaft of the steering member, the driving pulley 12 which is driven by an electric motor, and a following pulley which is connected with the driving pulley 12 through a belt, and integrally turns with the ball nut. For the driving pulley 12, both sides in the axial direction are freely rotatably supported by bearings 16 and 17, and the driving pulley 12 is equipped with a pulley main body 24 on which a plurality of tooth sections 23 are provided, and a pair of regulating members 25 and 26 which are attached to both of the end sides in the axial direction. Respective regulating members 25 and 26 are pinched by the internal rings 16a and 17a of the bearings 16 and 17, and the end sections of the pulley main body 24. COPYRIGHT: (C)2006,JPO&NCIPI |
