  • Clamping cylinder actuator
    Patent number: 6427992
    Abstract: A clamping cylinder actuator has a front end cover (7). A back surface (9) of the front end cover (7) has a joining surface (102) joined to a fixed member (100). A thin, flat gasket (30) formed from elastic rubber materials and such is interposed between the front end cover (7) and a front end surface of a cylinder (1) facing the front end cover (7). The gasket (30) is fitted on a boss (10) formed on the front end cover (7) and extends over the entire back surface of the front end cover (7) having a sealing surface (11) surrounded by the joining surface (12). When the front end cover (7) is fastened to the fixed member (100) with bolts (101), the gasket 30 is held between the front end cover (7) and the fixed member (100). The gasket (30) prevents the loosening of the bolts (101).
