PROBLEM TO BE SOLVED: To prevent coming off of a push nut from a shaft member. SOLUTION: The push nut includes a ring-like base part 51, and a plurality of extended parts 52 provided in a peripheral direction of the base part 51 and extended to a center O side of the base part 51. A sharp claw part 52b is provided on the extended part 52, and only the claw part 52b is fitted to a reduced diameter part 12 of a cylindrical part 10 inserted into an opening 53 of the base part 51, and a contact area with the reduced diameter part 12 is reduced, and biting force of the claw part 52b to the reduced diameter part 12 is increased, and the push nut 50 is surely fitted to the reduced diameter part 12.
