PURPOSE:To absorb the machining error, surely connect a master plate and a tool plate, eliminate a gap at the connection face between both plates, and improve the reproducibility of the connection position by pushing balls outward in the radial direction with the taper face of a piston. CONSTITUTION:When a piston member 16 is moved to the lock position, the piston member 16 pushes ball members 12 via the taper face 16e, and the ball members 12 are pressed and excited outward in the radial direction by the wedge effect of the taper face 16e. A tool member presses and excites a tool plate 3 upward via the taper face 16e, the tool plate 3 is excited to the master plate 2 side, and both plates 2, 3 are connected with no gap. |
