Steering device

A steering device for performing steering of a vehicle, the steering device comprising:

• a steering input shaft to which a steering member is attached;
• a movable body that rotatably supports the steering input shaft;
• and
• a first rail mechanism and a second rail mechanism that guide movement of the movable body in a front-rear direction of the vehicle, the first rail mechanism and the second rail mechanism being disposed at different positions from each other, wherein
• the first rail mechanism includes
• a first fixed rail that is fixed to the vehicle and that has a first raceway face,
• a first moving rail that is slidably attached to the first fixed rail, and that has a second raceway face, and also that is attached to the movable body, and
• a first rolling element row that is disposed between the first raceway face and the second raceway face, the first rolling element row including a plurality of first rolling elements that are capable of rolling,
• the second rail mechanism includes
• a second fixed rail that is fixed to the vehicle and that has a third raceway face,
• a second moving rail that is slidably attached to the second fixed rail, and that has a fourth raceway face, and also that is attached to the movable body, and
• a second rolling element row that is disposed between the third raceway face and the fourth raceway face, the second rolling element row including a plurality of second rolling elements that are capable of rolling, and
• a contact angle of each of the plurality of first rolling elements with respect to the first raceway face and the second raceway face, and a contact angle of each of the plurality of second rolling elements with respect to the third raceway face and the fourth raceway face, are different from each other.
