摘要： PROBLEM TO BE SOLVED: To ensure the stable sealing performance for a long period by mounting seal parts of double structure capable of contacting with and separating from an operating member in accordance with the operation of the operating member, around a pressure introduction inlet at a pressure chamber side, on an inner surface of a housing. SOLUTION: First of all, seal parts 21, 31 of concentric double structure consisting of the seal part 21 at an inner peripheral side and the seal parts 31 at an outer peripheral side, capable of simultaneously or approximately simultaneously contacting with and separating from an end surface 7a of an end member 7 of an operating member 5 in accordance with the operation of the operating member, are mounted around a pressure introduction inlet 14 at an end surface part 3b of a shell 3 on an inner surface of a housing 2. Whereby the seal parts 21, 31 compensate each other, as a result, the load on the seal parts 21, 31 are respectively reduced. Accordingly the generation of fatigue on the seal parts 21, 31 in the initial period which is found on an end seal by a conventional technique, can be prevented, and the stable sealing performance can be ensured for a long period.

摘要： PROBLEM TO BE SOLVED: To prevent the early occurrence of a settling phenomenon in a seal member by providing, on the seal member, a seal lip which is pressed by the pressure of a sealed fluid, when an operating member is stopped by the contact with an end surface part or stopped by a stopper, and brought into close contact with the working member. SOLUTION: In the state where the end member 7 of a working member 6 moving toward an end surface part 3b is stopped by the contact with the end surface part 3a of a shell 3, the seal lip 22b of the seal member 22 of an end seal 21 is pressed by the pressure of a pressure chamber 9 that is a sealed fluid pressure and closely brought into contact with the end surface 7a of the end member 7, whereby a sealing effect is attained. Therefore, the sealing is performed in the state where the seal lip 22b of the seal member 22 is in close contact with the end surface 7a of the stopped end member 7 with a prescribed contact pressure. Accordingly, the seal member 22 having the seal lip 22b is never strongly nipped between rigid members, so that the early occurrence of a settling phenomenon in the seal member 22 can be prevented, and the stable seal performance can be ensured for a long period.
