Abstract:
In a spring sheet structure of a hydraulic shock absorber having a sheet rubber seated on a spring sheet and supporting a spring through the sheet rubber, an end coil portion of the spring is stored in the sheet rubber, the spring sheet includes a movement restraint unit for restraining a movement of the sheet rubber, the sheet rubber includes an abutment unit corresponding to the movement restraint unit of the spring sheet, and the abutment unit of the sheet rubber is engaged with the movement restraint unit of the spring sheet while the sheet rubber is seated on a flat sheet surface provided in a circumferential direction of the spring sheet, thereby restraining a movement of the spring relative to the spring sheet.
