込んだオートテンシヨナ。 The plunger is slidably inserted into the plunger insertion hole formed in the body and whose lower part is open, and the insertion hole formed in the axial direction from the upper surface of the plunger has a closed end at the lower part, and the inside is used as a reservoir chamber. The lower part of the guide cylinder is inserted with a small gap between it and the inner peripheral surface of the insertion hole, and the lower parts of the hydraulic chamber and the reservoir chamber are formed between the lower closed end of the guide cylinder and the closed end of the plunger. is filled with hydraulic oil, the guide tube is provided with a radial hole that communicates the internal reservoir chamber with the minute gap, and the closed end of the guide tube is formed with a passage that communicates with the hydraulic chamber. A check valve is installed in the passageway to prevent hydraulic oil from flowing from the hydraulic chamber to the reservoir chamber, a spring receiver is provided on the upper outer periphery of the guide tube, and a tension adjustment spring is installed between this spring receiver and the upper end of the plunger. Jonah.
