- the width 14w of the engaging portion 14 is substantially the same size as the maximum outer diameter of the reinforcing bar gripping portion 13, and the upper surface 14a of the engaging portion 14 is provided at a position that coincides with the axis C.
- a flange-like stopper 15a is provided at the tip of the locking projection 15 to prevent the cylindrical locking projection 15 from being detached from the locking hole 16, and the stopper 15a can pass therethrough.
- An attaching / detaching hole 17 having an inner diameter is opened adjacent to the engaging hole 16, and a communication portion 18 having a width through which the engaging protrusion 15 can pass is provided between the attaching / detaching hole 17 and the engaging hole 16. Yes.
- the inner diameter of the locking hole 16 is set smaller than the outer diameter of the stopper 15 a which is larger than the outer diameter of the locking projection 15.
- six flat portions 13a are formed on the outer periphery of the reinforcing bar gripping portion 13 so as to form a regular hexagonal column.
- FIG. 4A prepare two reinforcing bar couplers 10x and 10y, and connect the two irons 13b of the reinforcing bar gripping part 13 of these reinforcing bar couplers 10x and 10y to be connected.
- the ends of the muscles l lx and l ly are inserted and screwed together, and the two reinforcing bar couplers 10x and 10y are fixed to the l lx and l ly ends of the respective reinforcing bars.
- the engaging portions 14 extending from the two are arranged so that their upper surfaces 14a face each other.
- the locking projection 15 can be fixed to the engaging portion 14 by being inserted into the locking hole 16 via the attachment / detachment hole 17 and the communication portion 18. Therefore, the two reinforcing bars 1 lx and 1 ly can be easily connected in a short time without using a screw tightening tool such as a spanner.
