CAM device, position adjustment device for steering wheel and assembly method for position adjustment device for steering wheel

摘要

It is possible to easily determine whether or not the combination of the driving side cam and the driven side cam is appropriate. The driven side recessed groove 47 is formed in a state recessed radially inwardly in the axial direction at two positions on the outer peripheral surface of the driven side cam 30 a which are opposite to each other in the radial direction. A portion of the outer peripheral surface of the driving side cam 29 a in the circumferential direction in the locked state is recessed radially inwardly in the axial direction over a portion where the phase of the driving side cam 29 a coincides with the driven side recessed groove 47 And forms the second drive recessed groove 46 in a state in which the phase in the circumferential direction in the unlock state coincides with the driven side recessed groove 47 in a state of being recessed in the radial direction inwardly in the axial direction.
