Abstract: A clutch for use in a steer-by-wire steering device for a vehicle is configured to switch between mechanically coupling and uncoupling a torque transmission path between a steering member operated by a driver and a wheel-turning unit configured to turn wheels. The clutch includes a position change member and a conduction path. The position change member is configured to change between a first position and a second position to switch between mechanically coupling and uncoupling the torque transmission path. The conduction path includes two points that come into contact with or separate from each other in accordance with positional change of the position change member. The conduction path is connected to an electric circuit configured to detect a change in a resistance value of the conduction path.

Abstract: A steering device includes: a plurality of electric motors 10 configured to be driven to turn wheels of a vehicle; and three or more drive systems 20 each configured to output a driving force for driving a corresponding one of the electric motors 10 to the corresponding one of the electric motors 10. A total of maximum driving forces each of which is a maximum value of a driving force of each drive system 20 of the steering device is set larger than a required driving force required to turn the wheels with the vehicle stationary, and in an event of a failure occurring in one of the three or more drive systems 20, a total of the maximum driving forces of other properly working drive systems 20 out of the three or more drive systems 20 amounts to the required driving force.

Abstract: A vehicle steering device includes a turning shaft held in a housing so as to be movable in the axial direction, a ball screw transmitting drive force produced by an electric motor to the turning shaft, a bearing supporting a nut, which is a component of the ball screw, so as to be rotatable relative to the housing, and annular elastic members that support side faces of the bearing in the axial direction of the turning shaft across the entire circumference, and are formed of an elastic material. The elastic members include respective first elastic portions having a first load characteristic that gently increases the ratio of compression load per a unit compression amount deforming in the axial direction of the turning shaft, and respective second elastic portions having a second load characteristic that keenly increases the ratio in comparison with the first load characteristic.

Abstract: A steering device includes: a steering shaft; an outer pipe; a first bearing that causes the steering shaft to be rotatable with respect to the outer pipe; and a front body that is disposed in front of the bearing in an axial direction, and the steering shaft; in which a first space into which the steering shaft is capable of being inserted is formed on a radially inner side of the front body, and a second space into which the outer pipe is capable of being inserted is formed on a radially outer side of the front body, and the steering device further includes a release mechanism that releases a relative restraint between the first bearing, a first front end portion, and a second front end portion in the axial direction in a case where the first bearing collides with the front body during the secondary collision.
