发明名称 油圧緩衝器のチェックバルブ構造
摘要 PROBLEM TO BE SOLVED: To reduce a stress concentration generated in the part of an outside annular section joined to a support piece while securing high lifting in the outside annular section in a check valve structure of a hydraulic buffer. SOLUTION: In the check valve structure of the hydraulic buffer 10, when a check valve 30 is opened, a distance between a scheduled collision contact part Fi on the edge E along a slit 34 of an outside annular section 32 possibly colliding and contacting with the tapered stopper surface 21 of a valve stopper 20 and the center of the check valve 30 is larger at the center side than both end sides of the slit 34 near a support piece 33 in a circumferential direction.
