Patent ID: 7806392

Claim:
A spring sheet structure of a hydraulic shock absorber comprising a sheet rubber seated on a spring sheet and supporting a spring through the sheet rubber, wherein an end coil portion of the spring is stored in the sheet rubber, the spring sheet includes movement restraint means for restraining a movement of the sheet rubber, the sheet rubber includes abutment means corresponding to the movement restraint means of the spring sheet, the abutment means of the sheet rubber is engaged with the movement restraint means 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, the sheet rubber comprises a rubber tube shaped into a circular arc on a single plane, the rubber tube has a closed end provided on one end of the circular arc and an opening portion provided on the other end of the circular arc, and includes a slit ranging from the closed end to be continuous to the opening portion along an inner circumference of the circular arc which enables a wire of the spring to be inserted into the rubber tube from the slit that is elastically enlargeable, and the rubber tube has a tube inside diameter equal to a diameter of the wire of the spring, and has a drain hole formed at a position offset toward an opposite side to the slit from a diameter of the rubber tube orthogonal to a plane including the circular arc.
