Description of the Related Art Conventionally, a reinforcing bar arranged inside a wall-like structure or the like is composed of a main bar or a distribution bar in the vertical and horizontal directions and a shear reinforcing bar connecting the main bar and the like. Then, as shown in FIG. 11, the conventional shear reinforcing bar is formed by bending a hook portion b1 at one end of a steel bar a and hooking the hook portion b on one of the main bars c1 and the like arranged in parallel. There is one that bends the end at the site to form a hook portion b2 and hooks the other main bar c2 or the like.
