摘要： PROBLEM TO BE SOLVED: To restrict unnecessary fluctuation of the speed change ratio by restricting axial displacement of pivotal shafts 23 and 23 of a power roller 6 when the transmission torque is fluctuated. SOLUTION: As a radial needle bearing 21a for movably supporting a base part 72 of a support shaft 8b supporting on a trunnion 7a the power roller 6, a complete needle type radial needle bearing without having a holder is used. Rigidity of the radial needle bearing 21a in the radial direction is improved to restrict a radial displacement of the power roller 6, and the described problem can be thereby solved.

摘要： PROBLEM TO BE SOLVED: To provide a steering device capable of compatibly realizing a collision energy absorbing structure during a collision of a vehicle body and a supporting structure of the steering reaction force by a simple rib structure.
SOLUTION: When a vehicle body is collided and a collision load of a predetermined value or more is applied, a component arranged on the forward side of the vehicle body of a steering gear box 4, for example, an engine 8 is moved backward of the vehicle body indicated by a two-dot-chain line from the normal position indicated by a solid line. When the engine 8 is moved backward of the vehicle body, the engine 8 is collided with a vehicle body front side end face 611 of a first rib 61, and the first rib 61 is firstly broken. Since the first rib 61 is broken, the connection rigidity of a flange part 7 to a hollow cylindrical part 41 is degraded, a second rib 62 and a third rib 63 are also broken, and the hollow cylindrical part 41 is moved backward of the vehicle body to effectively absorb the collision energy. Thus, a collision energy absorbing structure during the collision of the vehicle body and a supporting structure of the steering reaction force can be compatibly realized.
