<p>PROBLEM TO BE SOLVED: To realize, at low costs, a structure which can reduce an operation torque of an adjustment lever in holding a steering wheel at a position after adjustment.SOLUTION: In a cam device, continuous surfaces 24a and 24a which connect the to-be-driven side concave surface 21a continuously to the to-be-driven side convex surface 22a of a to-be-driven side cam surfaces 23a are composed of inner side continuous surfaces 31 and 31 and outer side continuous surfaces 32 and 32 on the radial-direction outer side to the inner side continuous surfaces 31 and 31. The height of the outer side continuous surfaces 32 and 32 relative to the to-be-driven side concave surfaces 21a and 21a at positions matching the inner side continuous surfaces 31 and 31 in the circumferential direction is smaller than the height of the inner side continuous surface 31 and 31. The outer side continuous surfaces 32 and 32 are connected continuously and smoothly to the to-be-driven side convex surfaces 22a and 22a, and the connection positions X is shifted from the connection positions Y where the inner side continuous surfaces 31 and 31 are connected continuously to the to-be-driven side convex surfaces 22a and 22a in one side of the circumferential direction.</p> |
