PROBLEM TO BE SOLVED: To assemble as many kinds of composite driving force transmission parts as possible by forming a recessed connection part at one axial side part of each driving force transmission member to be connected, and forming a protruding connection part at the other side part. SOLUTION: In a gear member 103 constituting an assembly 500, a recessed connection part 103a is formed on one side part in an axial direction, and a protruding connection part 103b protruded in a separating direction from one side part is formed at the other side part on the opposite side. Recessed connection parts and protruding connection parts are respectively formed at the axial side parts of gear members 101, 102, 104 in the same way as the gear member 103. The respective gear members 101-104 are connected by fitting the protruding connection parts into the recessed connection parts to constitute the assembly 500. Ten kinds of composite driving force transmission parts can therefore be assembled by preparing four kinds of gear members 101-104 so as to be able to assemble a larger number of composite driving force transmission parts than the number of kinds of gear members. |
