PIPE BENDER

PROBLEM TO BE SOLVED: To provide a pipe bender with which a pipe is accurately bent even when it is a thin pipe having high rigidity such as a stainless steel pipe and highly accurate pipe products are obtained. SOLUTION: This pipe bender 10 is provided with a center shaft part 40 for bending, a pipe holding part 50 for situating the planned bending part Pa of the pipe in the bending/guiding groove 41 in the center shaft part for bending by holding the pipe P and rotary clamp parts 60A, 60B with which the planned bending part of the pipe is held between themselves and the bending/guiding groove and which are rotatable around the center shaft part for bending and, by the rotation of the rotary clamp parts, the planned bending part of the pipe is bent along the bending/guiding groove. In the rotary clamp part, a pressing side groove 61 for holding the planned bending part between itself and the bending/guiding groove in the center shaft part for bending is formed and also hooks 62, 63 for locking on the center shaft part for bending are formed on at least one side in the width direction of the groove of the pressing side groove.
