の範囲第１項または第２項に記載の把持部材。[Claims for Utility Model Registration] 1. A gripping member that is attached to an upper chuck and a lower chuck for clamping a round bar-shaped workpiece, and the upper gripping piece has a gently sloped surface that rises toward the rear when viewed from the side. The lower gripping piece has an approximately L-shaped side surface with a rear surface that is approximately vertical and a front surface that is less inclined than the rear surface, thereby stably holding the workpiece during cutting and preventing appropriate distortion. A gripping member for chuck characterized by forming a mechanism. 2. The gripping member according to claim 1, which forms a horizontal surface that supports the lower peripheral end of the workpiece at the side end of the lower gripping piece as a distortion prevention mechanism during cutting. 3. As a distortion prevention mechanism during cutting, one or more relief grooves are provided at the lower end of the front surface of the upper gripping piece,
The gripping member according to claim 1 or 2, further comprising a relief groove formed at the upper end of the front surface of the lower gripping piece at a position substantially offset from the relief groove.
