Claims

[Scope of utility model registration request]

A lower end head portion having a tapered surface expanding downward, a deformed reinforcing bar having a stepped portion positioned above the lower end head portion and abutting against the upper end surface of the collar to prevent the collar from coming off, and expanding downward. A substantially cylindrical cotter having a tapered surface that opens and is press-fitted between the modified reinforcing bar and the collar, and a slit is formed in the length direction, and a slit is formed in the length direction, and the slit is formed in the head part and the step part. and a collar located on the outer circumferential side of the deformed differential reinforcement between the two holes, and a two-step hole having an upward step supporting the lower end surface of the cotter and a small diameter portion capable of accommodating the head portion, The anchor is configured such that the irregular reinforcement, the cotter and the collar are integrally fixed to the two-step hole by driving the irregular reinforcement into the bottom of the two-step hole. Fixed structure.
