摘要： A bend die comprises a clamp member having a first groove part of half-circular cross section on its outer peripheral surface with a fitting recess formed on the first groove part and extending in a peripheral direction by a first predetermined length on a planar surface perpendicular to a rotary axis, and a counter pressure member having a second groove part of half-circular cross section formed on its outer peripheral surface, and a fitting protrusion extending in a peripheral direction by a second predetermined length from a tip end portion of the second groove part. The fitting protrusion is positioned in the fitting recess so that a pipe-receiving groove of half-circular cross section is formed. The first and second groove parts are hingedly connected to one another about the rotary axis so as to be rotated relative to each other.
