<p><P>PROBLEM TO BE SOLVED: To provide a shock absorber for conducting closing movement at the time of moving from a fixing means more gradually to provide more comfortability. <P>SOLUTION: The check valve 10 has a valve plate 11 and a valve seat 12 for interacting with the valve plate. When flow rate is slow, the valve does not close a flow in any direction substantially. When flow rate is faster, the valve closes in the direction the piston moves from the cylinder. The valve plate 11 has more flexibility than the valve seat 12. When the piston moves from the cylinder, a first position 31 on the valve plate 11 conducts closing movement earlier than second positions 32, 33 of the valve plate 11. An opening part 14 is defined for the valve seat 12 and both the first position 31 and the second positions 32, 33 are sealed by border of the opening part 14. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
