Abstract: A steering device that holds a steering member in such a manner that the steering member is movable between an advanced position where a driver can steer the steering member and a retracted position located closer to the front of a vehicle. The steering device includes: a fixed member attached to a vehicle body; a movable member to which a steering shaft holding the steering member is rotatably attached; and an upper guide mechanism and a lower guide mechanism that linearly guide the movable member with respect to the fixed member. An end on the advancing side of the upper guide mechanism is located further toward the advancing side than an end on the advancing side of the lower guide mechanism in an advancing and retracting direction of the movable member.

Abstract: A steering apparatus for use in steering a vehicle includes: a movable body to which an input device is attached, the movable body configured to move back and forth in an extend-retract direction between a first position closer to the front of the vehicle and a second position closer to the driver; an intermediate guide that guides the movable body in the extend-retract direction, and moves back and forth in the extend-retract direction; a base guide that is attached to the vehicle and guides the intermediate guide in the extend-retract direction; a first extend-retract mechanism including an extend-retract drive source that causes the intermediate guide to move back and forth relative to the base guide; and a second extend-retract mechanism that causes the movable body to move back and forth relative to the intermediate guide by using driving force of the extend-retract drive source.

Abstract: A steering device for steering a vehicle includes a movable member, a holding member, an impact absorbing member, a movement driving unit, and a controller. The controller is configured to perform first control and second control by which the movement driving unit is controlled. The first control is a control for moving the movable member along an axial direction of a shaft member within such a range that a front end of at least one of the shaft member and the movable member is located rearward of a space for movement in the front-rear direction of the vehicle. The second control is a control for moving the movable member along the axial direction within such a range that the front end portion is located inside the space for movement.

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.

Abstract: A vehicle steering system includes a steering operation mechanism configured to steer a steered wheel, and a steering operation motor configured to apply a drive force for steering the steered wheel to the steering operation mechanism. The steering operation mechanism includes an input shaft to which the drive force from the steering operation motor is input, an output shaft configured to output the drive force from the input shaft to the steered wheel, and a coupling mechanism configured to couple the input shaft and the output shaft to each other. The coupling mechanism includes a first universal joint and a second universal joint that transmit the drive force from the input shaft to the output shaft in a state in which the output shaft is angularly offset from the input shaft. The output shaft constitutes a part of a suspension.
