As described in the publication, a height-adjusting piston is provided at the top of the piston rod of the hydraulic shock absorber that extends upward from the axle, and an inner cylinder that fits into the piston and an outer cylinder that is fixed to the vehicle body. An annular mount rubber is installed between the cylinder and the mount rubber and a lid member on the top surface of the outer cylinder to form a variable volume oil chamber, and a spring seat of the hydraulic shock absorber is attached to a receiving seat in the center. It is known that the piston is brought into contact with the step part of the piston rod through the seat, and the piston is supported by the seat, but in this case, the piston is screwed onto the rod with its central cylindrical shaft, so its installation is difficult. Although it is stable, the step part of the rod bulges out at a nearly right angle due to drawing processing, etc., and forms a horizontal receiving surface on the upper surface, which causes stress concentration on the step part of the rod, which tends to reduce the strength. .

An annular mount rubber 8 is attached between the inner cylinder 5 to be fitted and the outer cylinder 7 fixed to the vehicle body 6 side, and the rubber 8 and the lid member 9 on the upper surface of the outer cylinder 7 are used to form a variable volume type. Oil chamber 1
0, and the spring seat 13 of the hydraulic shock absorber 2 is brought into contact with the stepped portion 15 of the piston rod 3 via the central seat 14, so that the piston 4 is supported by the seat 13. The piston 4 is sandwiched from above and below by a nut 20 that is screwed into the threaded portion of the upper end of the rod 3 and a cylindrical member 11 that is fitted into the rod 3, and the cylindrical member 11 is held between the spring seat 13 and the cylindrical member 11.
Further, the receiving seat 14 and the stepped portion 15 are supported by downward and upward conical receiving surfaces 14a, 1.
5a are brought into contact with each other.

る。 The shock absorber 2 consists of a lower cylinder 16, a piston 17 inside the cylinder, and the rod 3 extending upward from the cylinder 16, and is equipped with the spring 12 on its outer periphery, which is connected to the spring seat 13 and the lower spring. The piston 4 is supported from above and below by a seat 18 and has a dust cover 19 inside.The piston 4 is fitted onto the top of the rod 3 and fixed thereto with a nut 20. Pressure oil can be freely introduced into the chamber 10 through an oil supply port 21. The receiving surfaces 14a, 15a are generally about 45 degrees as shown in the figure, but may range from 30 degrees to 80 degrees. In the drawings, reference numeral 22 indicates a stopper lever on the upper surface of its outer periphery, which supports the inner cylinder 5 from its lower surface.

の効果を有する。 In this way, according to the present invention, the piston 4 is held between the top and bottom by the nut 20 screwed onto the threaded portion of the upper end of the rod 3 and the cylindrical member 11 fitted into the rod 3, and the cylindrical member 11 is held by the spring. Since it is supported by the seat 13, the tightening torque of the nut 20 can be transmitted to the seat 13, and the piston 4 is firmly attached to the rod 3.
Moreover, the catch 14 of the spring seat 13 and the rod 3
The stepped portions 15 are formed on each of the conical receiving surfaces 14a and 15a, so compared to a structure in which the stepped portions 15 are bulged at right angles, stress concentration on the stepped portions 15 is alleviated and the seat 13 is more easily received. Since the contact area with the surface increases and the friction effect increases, this helps to prevent the nut 20 screwed into the threaded portion from loosening, and the piston 4 is stably attached to the rod 3 over a long period of time. have
