PURPOSE:To firmly and surely couple a ring-like member with a hollow shaft, irrespective of the material of the ring-like member and the wall thickness of the hollow shaft, in a method in which a ring-like member such as a cam member or the like is adapted to be coupled to the hollow shaft. CONSTITUTION:A hollow shaft 11 formed therein with a through-hole 11b piercing from the outer periphery to the inner periphery of the hollow shaft and movably inserted therein with a coupling pin 13 directed toward the outer periphery, is fitted thereon with a ring-like member 15 formed at its inner periphery with a recess in which a part of the coupling pin 13 is inserted so that the through-hole 11b overlaps the recess. Thereafter, resin P is injected into the through-hole 11b from the inner periphery of the hollow shaft 11, and is then cured, thereby it is possible to firmly couple the ring-like member 15 with the hollow shaft 11. |
