られることを特徴とする倒立型油圧緩衝器。 An outer tube 4 whose upper end is closed, an inner tube 5 whose lower end is closed and which is slidably fitted into the outer tube 4 from below, and an inner tube 5 which is disposed coaxially within the inner tube 5. a cylinder 8 fixed to the closed end of the outer tube 4; a piston 25 slidably fitted into the cylinder 8 and fixed to the lower end of a piston rod 19 connected to the closed end of the outer tube 4; a spring collar 52 coaxially surrounding the piston rod 19 and cylinder 8 while being connected to the closed end of the inner tube 5; and a buffer spring 53 interposed between the lower end of the spring collar 52 and the closed end of the inner tube 5.
The spring collar 52 has a small diameter cylindrical part 52a whose upper end is connected to the closed end of the outer tube 4, and a small diameter cylindrical part 52a whose upper end is connected to the lower end of the small diameter cylindrical part 52a while being formed in a tapered shape that becomes larger in diameter as it goes downward. A conical portion 52b coaxially connected and a large diameter cylindrical portion 52 coaxially connected to the lower end of the conical portion 52b.
In the inverted hydraulic shock absorber consisting of c, the outer circumference of the cylinder 8 has the conical portion 52b during compression operation.
An inverted hydraulic shock absorber characterized in that a lock portion 60 having a tapered outer surface facing the inner surface of the conical portion 52b during compression operation is provided to form an annular oil lock chamber 61 between the inner surface of the conical portion 52b and the inner surface of the conical portion 52b. .
