PROBLEM TO BE SOLVED: To increase shaft support precision and to improve assembly workability.SOLUTION: Support pieces 114A and 114B having a first mechanism part M101 configured therein, of a shaft support part A101 are formed of elastic resin and face each other to extend like a fork. A turning shaft 133 is fixedly provided on a butt 241 having a second mechanism part M102 configured therein. Shaft support holes 132 are formed in recessed guide parts 131 formed in respective support pieces. When the butt 241 is assembled, the turning shaft 133 is guided by the guide parts 131 in a state where space between the support pieces 114A and 114B is widened by elastic deformation, and is fitted into the shaft support holes 132 due to positional correspondence between the shaft support holes 132 and the turning shaft 133, and therefore, the state where the space between the support pieces 114A and 114B is widened is released and the turning shaft 133 is freely turnable relative to the shaft support holes 132. |
