Abstract
A steering device includes a movable body that rotatably supports a shaft member to which a steering member is attached, and first and second rail mechanisms that guide movement of the movable body in a front-rear direction. The first rail mechanism has a first rolling element row that is disposed between a first raceway face of a first fixed rail and a second raceway face of a first moving rail. The second rail mechanism has a second rolling element row that is between a third raceway face of a second fixed rail and a fourth raceway face of a second moving rail. A contact angle of each of a plurality of first rolling elements with respect to the first and second raceway faces, and the contact angle of each of a plurality of second rolling elements with respect to the third and fourth raceway faces are different from each other.
