To provide a fastener which achieves favorable workability during assembly.SOLUTION: A fastener 55 is coupled to both ends of a shaft 53 which is inserted into a base 9 and a rotating body 33 in a state where both ends of the shaft protrude. The fastener comprises: a base part 60 extending along an axial direction of the shaft; and a pair of engagement parts 61 provided at both ends of the base part and including mutually opposing first surfaces 63. Each of the pair of engagement parts has: a receiving hole 65 having a bottom section 69 recessed from the first surface and opposing the end of the shaft; a groove section 67 extending from the receiving hole to an edge section 71 of the engagement part and allowing passage of the end of the shaft; and a locking part 77 provided in the groove section and configured to lock the shaft.SELECTED DRAWING: Figure 5
