Claims

[Scope of utility model registration request]

a cylinder, a partition member disposed within the cylinder that partitions the inside of the cylinder into a first and second liquid chamber, the partition member having two passages communicating the two liquid chambers; first and second check valves that are independently provided in connection with the passageway and allow liquid to flow from the first liquid chamber to the second liquid chamber, but prevent reverse flow; 1st
and a second check valve, the first check valve allows the liquid to flow until the pressure in the first liquid chamber reaches a predetermined value, and the first and second check valves include:
A hydraulic shock absorber that causes liquid to flow after the pressure in the first liquid chamber reaches a predetermined value.
