PROBLEM TO BE SOLVED: To enable a driver to be free from anxious about deterioration of ride comfort and generation of abnormal sound in a vehicle.SOLUTION: A valve structure includes: a partition wall body 3 partitioning into one chamber R1 and the another chamber R2; a valve seat 3e formed on an end face opposed to the one chamber R1 or the another chamber R2 of the partition wall body 3; a first leaf valve 41 for seating an outer peripheral end portion on the valve seat 3e and making it leave therefrom; and a second leaf valve 42 laminated on a back surface of the first leaf valve 41. The second leaf valve 42 has on a location in a circumferential direction of the outer peripheral end portion, a low rigidity portion A which makes easy an operation of making the outer peripheral end portion leave from the valve seat 3e in the first leaf valve 41, and the low rigidity portion A causes its own flexural rigidity to lower than that of the other portion in a circumferential direction in the outer peripheral end portion of the second leaf valve 42. |
