PROBLEM TO BE SOLVED: To prevent the generation of noise in pushing knob without using a grease by providing an impact absorbing member of the soft resin formed in a surface of one or both of the outer periphery of a rod for pushing the top surface of a switch part and the inner periphery of a slide hole. SOLUTION: An impact absorbing rod 10 is fonned of a rod body 11 made of the hard resin such as ABS and an impact absorbing member 12 of the soft resin formed in an outer peripheral surface of a slide part of the rod body 11. As the soft material for absorbing the impact noise of the rod, the olefin group resin is appropriate for the case of simultaneously forming the impact absorbing member 12 and the impact absorbing rod 10 with the double color formation. With this structure, even in the case where a slide part 1Ok of the impact absorbing rod 10 collides with a slide surface lz of a through hole lk, since the surface of the impact absorbing rod 10 is formed with the impact absorbing member 12, generation of noise is prevented.
