The clamping device has a guide hole (22), a screw hole (21), a clamp member (1) having a clamp portion (2), and a screw member (10) screwed with the screw hole (21). The screw member (10) can be engaged with the clamp member (1) in movement both in the first and second directions and the guide hole (22) has a first cam surface (22a) converting a force in the first direction received from the screw member (10) into a force for moving the clamp member (1) in a direction toward the cutting insert (30) and a second cam surface (22b) converting a force in the second direction into a force for moving the clamp portion (2) in a direction away from the cutting insert (30). |
