Abstract: A steering column device includes a steering column; and a telescopic actuator. The steering column includes a first column member, a second column member assembled to the first column member in a manner of being displaceable relative to the first column member in an axial direction, and a low-friction sliding member disposed between the first column member and the second column member. The telescopic actuator includes a telescopic motor, and displaces the second column member in the axial direction with respect to the first column member by using the telescopic motor as a drive source.

Abstract: A steering section of a steer-by-wire system includes a handle having a center axis of rotation arranged in the front-rear direction, and a handle-support shaft having a center axis arranged in the front-rear direction and that is supported so as not to be able to rotate about the center axis with respect to the vehicle. The handle is rotatably supported so as to be able to rotate about the center axis of rotation with respect to the rear-end portion of the handle-support shaft. The center axis of the handle-support shaft is arranged so as to be offset upward with respect to the center axis of rotation of the handle.

Abstract: Provided is a structure of a steering section of a steer-by-wire system capable of maintaining large leg space in the driver's seat in the vertical direction. The steering section of a steer-by-wire system includes a handle 1a having a center axis of rotation ? arranged in the front-rear direction, and a handle-support shaft 2a having a center axis ? arranged in the front-rear direction and that is supported so as not to be able to rotate about the center axis ? with respect to the vehicle. The handle 1a is rotatably supported so as to be able to rotate about the center axis of rotation ? with respect to the rear-end portion of the handle-support shaft 2a. The center axis ? of the handle-support shaft 2a is arranged so as to be offset upward with respect to the center axis of rotation ? of the handle 1 a.

Abstract: After a cup bearing (13a) is incorporated into a circular hole (11c) of a coupling arm portion (10c) forming a yoke, a notch (25) having a V-shaped cross section is formed in a portion near the periphery of the circular hole (11c) on an outer side surface of the coupling arm portion (10c). Thereafter, a thin-walled portion (27) having a substantially trapezoidal cross section formed in a radially inner portion of the notch (25) in an opening edge portion of the circular hole (11c) is plastically deformed inward in a radial direction to form a staking portion (14a). Therefore, it is possible to achieve a method of assembling a joint cross type universal joint and a joint cross type universal joint which can form the staking portion for preventing the cup bearing from falling off without complicating the staking work.
