Abstract: PROBLEM TO BE SOLVED: To provide a fastener having a special type so that the displacement of angle between a punch and the vertical axis of a tool generated from the load at the fastening time becomes small. SOLUTION: In the fastener for deformed fastening comprising a frame (1) opened at one part side, a driving part (4) disposed on the frame (1) and having a movable punch (5), and a tool holder (12) for supporting the tool (13) so as to be faced to the punch on the frame (1); the tool holder (12) receives plastic deformation according to the increase of the load at the fastening time, and is designed so that this deformation at least partially counterbalances a load dependent widening of the frame (1) on the tool (13).
