The base end of an adjustment lever (18a) is joined to a drive-side cam (26b), and an adjustment rod (19a) is press-fitted into a lever-side through-hole (39) provided in the base end of the adjustment lever (18a). The adjustment rod (19a) is inserted through a center hole (35b) in the drive-side cam (26b) without interference provided therebetween. Thus, a structure in which the adjustment lever (18a) is prevented from rattling relative to the adjustment rod (19a) even if the drive-side cam (26b) consists of sintered metal or ceramic is provided without an increase in manufacturing cost. |
