COUPLER FOR THREADED REBAR AND THREADED REBAR EQUIPPED WITH SAID COUPLER
To provide a coupler for a threaded reinforcing bar in which torque management is easy without filling a sleeve with grout. A coupler 10 includes one main cylinder 11, and two sub-cylinders 12, 13. A hole in an axial direction formed in the inside of the main cylinder is a through hole H5 to which a thread M4 of the reinforcing bars is screwed, and outer peripheral screws 6, 7 are formed in the outer peripheries of the right and left half bodies of the main cylinder. The screws have pitches P6, P7 that are different from a screw pitch P4 of the thread M4 of the reinforcing bars. The sub-cylinders are formed with nut portions 14, 15 in one side ends of the sleeve portions 8, 9 covering the outer peripheries of the right and left half bodies of the main cylinder, sleeve inner peripheral screws F8, F9 that are screwed with the outer peripheral screws 6, 7 are formed in the sleeve portions 8, 9, and the nut portions are formed with nut portion female screws F14, F15 to which the thread M4 of the reinforcing bar is screwed.
