A to-be-engaged groove is formed in one end of the rotary shaft. An input gear made of a synthetic resin is fitted to the one end of the rotary shaft, and an engaging projection that engages with said to-be-engaged portion is formed in a portion of the input gear that is fitted to the rotary shaft.
