<p>PURPOSE:To obtain a clamping device which can positively clamp a work by absorbing and relaxing a centrifugal force operated in a direction for releasing clamping when a rotor rotates. CONSTITUTION:A rotary arm 13 of a retainer mechanism for pressing the outer periphery of a work 4 set on a rotor 1 is provided with a function as a balance weight means for absorbing centrifugal force operated in the direction for releasing clamping according to the rotary of the rotor and a linking mechanism 11 for rotating the retainer mechanism 10 at a clamping position and an unclamping position can be locked, by the elastic force of a follower link 22, at a position where the connection point between a drive link 21 and the follower link 22 slightly exceeds the link rotary upper dead center when clamping the work.</p> |
