The working medium is partially introduced into working space through ventilation aperture to prevent working medium deflated state in working space. The passage openings (7,8) have free cross-section that covers cross section of working space in plane of displacement direction of slides (5), so that passage openings are overlapped each other in first relative displacement position of slide, and passage openings are partially covered to block cross section of working space.",
