A pair of left and right hooks are hooked at two places on the reinforcing bar, and the two places are used as fulcrums, and a middle part thereof is pushed with a piston rod of a hydraulic cylinder to bend the reinforcing bar. A cylinder portion attached to the cylinder so as to be able to move back and forth and coaxially rotatable, and a pair of left and right arms extending from the cylinder portion to the front side and having the engaging portion at the tip portion, and the positioning device comprises a cylinder. And a cylindrical portion provided with a longitudinal concave groove with an open front side to which the protrusion is fitted. The forward position of the rebar holding metal fitting is at the bottom of the concave groove. And determined by abutment of the projection, the reverse position of the reinforcing bar holding fixture is one that has a configuration which is determined by the abutment of the front end surface of the cylindrical portion and the projection.

決めして半曲げし（約１２０度に曲げ）、２回目は鉄筋
保持金具を後進位置に位置決めして全曲げする（９０度
に曲げる）ことができる。According to the present invention, since the rebar holding bracket can be positioned at the front side and the rear side of the cylinder, that is, at the forward position and the reverse position, for example, when a straight rebar is bent at a right angle, the first rebar holding is performed. The metal fitting can be positioned at the forward position and bend halfway (bend to about 120 degrees), and the second time, the rebar holding metal fitting can be positioned at the reverse position and bend fully (bend to 90 degrees).
【００１５】このことは、ピストンロッドの１回の往動

済む。その結果、鉄筋曲げ具全体が小型かつ軽量になる
通常、３Ｋｇ程度になる。This means that the piston rod bends at a right angle in one forward movement (stroke) but is bent in two forward movements (stroke). For this reason, the piston rod can be short, and accordingly, the hydraulic cylinder can be thin and short. Further, the arm portion of the holding fitting can be shortened. As a result, the rebar bending tool as a whole becomes smaller and lighter, usually about 3 kg.
【００１６】鉄筋曲げ具が小型かつ軽量になるので、こ
れを配筋場所に携帯し、その場所で鉄筋を曲げながら配
筋をすることができる。Since the reinforcing bar bending device is small and lightweight, it can be carried to a reinforcing bar location and the reinforcing bar can be bent while bending the reinforcing bar there.
【００１７】また、鉄筋曲げ具は、小型かつ軽量である

に挿入して鉄筋を曲げることができる。Further, the reinforcing bar bending tool is small and lightweight, and the reinforcing bar holding member rotates coaxially around the cylinder. Therefore, even if the reinforcing bar is arranged, the direction of the reinforcing bar holding member is turned while rotating the reinforcing bar holding member. Alternately, the rebar can be bent by inserting it into the narrow space between the rebars.

トンロッドが鉄筋から外れ難い。Further, as described above, since the rebar is bent by two forward movements (strokes) of the piston rod, one stroke is shortened. For this reason, the piston rod does not easily come off from the rebar when the rebar is bent.
