To achieve weight saving in a gear subassembly in which a gear constituting a part of reduction gears and a cam constituting a part of a link mechanism are integrated.
According to a subassembly 1, a gear 3 is provided by resin-molding with a metal plate 46 used for fastening to a rotating shaft 30, and a metal nut 47 used for fastening to a cam 5 serving as insert parts. With this, by making a portion of the gear 3, which requires high strength, from metal and by making a portion, which does not require very high strength, from resin, the gear 3 can be reduced in weight as compared with a case of the entire gear 3 being made from metal. As a result, weight saving can be achieved in the subassembly 1 in which the gear 3 constituting a part of the reduction gears 2 and the cam 5 constituting a part of the link mechanism are integrated.
