とするシヨツクアブソーバ。 Insert a cylindrical piston rod into the cylinder,
A piston is attached to the tip of the cylinder to divide the inside of the cylinder into two fluid chambers, and a throttle hole is formed in the wall of the piston rod to communicate the cylinder with the inside of the cylinder rod, and a spool is slidably inserted into the cylinder rod. A piezoelectric body is arranged to face the cylinder rod at a predetermined distance from the surface of the spool opposite to the piston, and an incompressible liquid is formed between the opposing surfaces. The diameter of the portion of the inner peripheral surface of the piston rod where the spool and the liquid chamber are in contact is smaller than the diameter of the portion where the liquid chamber and the piezoelectric body are in contact with each other. A shock absorber characterized in that the area of the piezoelectric material is smaller than the area of the opposing surface of the piezoelectric material.
