Claims

[Scope of utility model registration request]

Two pistons, front and rear, are provided at the tip of the piston rod with an appropriate space between them, and a seal ring is movably inserted between them, and is slidably fitted into the damper case.
In an open stay in which an oil ring closes the gap between one of the front and rear pistons and the damper case during expansion or compression to generate a damping force, a square hole is provided in the axial direction from the center of the end surface of the piston rod, and the square hole is is connected to the space between both pistons through a diametrical passage provided in the piston rod and a number of radial slits provided on the inner end surface of one of the front and rear pistons and smaller than the square hole, and is connected to the space between both pistons during compression. An open stay characterized in that a damping force is generated by causing the water to flow through the slit to the square hole.
