懸架装置のシール構造。[Claims for Utility Model Registration] (1) A cylinder containing oil therein, and a rod inserted from one end of the cylinder so as to be movable back and forth in the axial direction of the cylinder, and the cylinder and the rod are connected together. In the seal structure of a suspension device, the sealing part is provided with a sealing part in the sliding part of the rod, and the sealing part is made of an annular groove provided in the cylinder and opens toward the rod side, and is made of an elastic material and is housed in the annular groove. It has a high-pressure seal portion including an O-ring and a low-friction resin seal cap disposed between the O-ring and the rod in the annular groove, and the inner circumferential surface of the seal cap is in contact with the rod. What is claimed is: 1. A seal structure for a liquid-filled suspension device, characterized in that the outer peripheral surface is in close contact with the O-ring, and has O-ring holding surfaces that protrude toward the O-ring at both ends in the axial direction. (2) The above-mentioned seal part consists of the above-mentioned high-pressure seal part and a low-pressure seal part located on the outer end side of the high-pressure seal part in the axial direction. A sealing structure for a liquid-filled suspension device according to claim 1, characterized in that a sealing material having a lip is provided. (3) A liquid-filled suspension according to claim 2 of the utility model registration claim, characterized in that a low-friction sliding bearing that slides on the rod is disposed between the high-pressure seal portion and the low-pressure seal portion. Seal structure of the device. (4) A drain flow section that guides oil from the low pressure seal section is connected to the low pressure seal section, and this drain flow section is connected to a hydraulic pressure supply system that can supply oil into the cylinder. A seal structure for a liquid-filled suspension device according to claim 3 of the registered utility model, characterized in that:
