Zusammenfassung:In a reduction-transmission mechanism, a plurality of output members are arranged at such positions that a size that is the sum of a fitting clearance formed between an outer periphery of each output member and a corresponding one of needle roller bearings, a fitting clearance formed between the needle roller bearing and an inner periphery of an input member, which defines a corresponding one of a plurality of pin insertion holes, and a radial internal clearance in the needle roller bearing is smaller than a size that is the sum of a fitting clearance formed between a ball bearing and an outer periphery of an eccentric portion, a fitting clearance formed between the ball bearing and an inner periphery of the input member, which defines a center hole, and a radial internal clearance in the ball bearing.
