Claims

[Scope of utility model registration request]

A hydraulic shock absorber comprising a partition member that partitions the inside of a cylinder into two liquid chambers and communicates the two liquid chambers via a port, and a valve body that cooperates with the partition member, wherein the partition member has one end surface. It has a plurality of land portions protruding from the plurality of land portions in the axial direction of the cylinder, and among the plurality of land portions, the outermost land portion that the valve body comes into contact with when shutting off the port is one of the plurality of land portions. A hydraulic shock absorber having a length that does not exceed a line connecting the edge of the best land portion and the edge of the end face.
