PROBLEM TO BE SOLVED: To facilitate pulling of a pulley from a crankshaft (rotating shaft). SOLUTION: After the pulley 1 is fastened to the crankshaft 200 by a bolt 210, a C-shaped stop ring (ring member) 10 is attached to the inner surface of a boss part 21 of the pulley 1, so that the C-shaped stop ring 10 is engaged with (abuts on) the bolt 210, in the process of loosening the bolt 210 to remove the pulley 1, to transmit an axial force in the pulling direction of the bolt 210 to the pulley 1. According to such a structure, the pulley 1 can be easily pulled out. Further, since two steps of "removal of the bolt 210" and "pulling of the clamp pulley 1" can be simultaneously performed, the pulley removing operation can be more efficiently performed.
