<p><P>PROBLEM TO BE SOLVED: To reduce manufacturing cost and to further downsize in a known clutch device. <P>SOLUTION: A pressure piston 1 is guided to slide in housings 5, 15, 1, the housings 5, 15, 1 and the pressure piston 1 surround a pressure chamber 11, the pressure chamber can be pressurized by a pressure medium 24 for generating pressure, and a balance piston 2 is provided for generating pressure in the opposite direction on the pressure piston. In the balance piston, when a clutch 4 is moved in a sliding direction of the pressure piston, it is held so as not to move basically with respect to the housing, it surrounds a balance chamber which can be pressurized by an opposite direction pressure medium for generating a pressure in the opposite direction along with the housing and the pressure piston, and the balance piston 2 is held so as not to move by latch mechanisms 25.1, 29.1, 30.1, 31.1. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
