Claims

[Scope of utility model registration request]

A damper comprising a cylinder member whose lower end is attached to a wheel side member, and a rod member which is fitted into the cylinder member so as to be slidable in the axial direction and whose upper end is attached to a vehicle body side member. A suspension spring is interposed between the two and a hydraulic cylinder device comprising a cylinder fixed to the rod member and a plunger fitted in the cylinder so as to be slidable in the axial direction is provided. Hydraulic vehicle height adjustment for an automobile in which a plunger supports an atsupahspring seat and a helper that support the upper end of the suspension spring so that they can be moved and displaced in the axial direction relative to the rod member as the plunger slides in the axial direction. In the device, the axial length of the plunger is configured to be shorter than the permissible axial sliding stroke of the plunger with respect to the cylinder, and a suspension spring is provided on the outer periphery in a low vehicle height state where the plunger is at the top end of the cylinder. The cylindrical part of the Atsupa spring seat, which has a supporting spring support part and a cylindrical part protruding upward in the center, is mostly located inside the cylinder, and the spring support part is located at the bottom of the lower edge of the cylinder. A structure in which the Atsupa spring seat is supported on the lower surface of the plunger so as to be closely opposed to the atsupa spring seat, and the helper is supported on the lower surface of the plunger with its upper portion located inside the cylindrical portion of the Atsupa spring seat. A hydraulic vehicle height adjustment device for an automobile, characterized by:
