<p>A first piston (4), which is connected to an output rod (2) and inserted in a housing (3), is driven upward by a pressure fluid. As a result of the downward movement of a second piston (6) disposed above the first piston (4), a wedge-type force multiplication mechanism (M) disposed above the first piston (4) drives the output rod (2) with a multiplied force.</p> |
