Claims

[Scope of utility model registration request]

The inner tube and the outer tube are slidably fitted together, and a seat pipe is installed concentrically from the end of the inner tube into the outer tube, and the upper part of the sheet pipe is made to look into the inner tube. A piston equipped with a damping force generating mechanism is slidably installed in the holder, the rod of the piston is pulled out from the seat pipe and inserted into the inner cylinder, and the upper end of the rod is attached to a fork bolt that closes the end of the inner cylinder. In a front fork that is screwed together, a hole is drilled in the lower part of the fork bolt through the outer circumference of the rod, the center of the rod, and the upper end of the rod so that the upper oil chamber in the seat pipe and the upper part of the oil chamber in the inner cylinder communicate with each other. The oil passage is rotatably inserted and screwed into the center of the fork bolt, and the oil passage has a conical lower end, and the upper part serves as a rotating engagement part to adjust the oil output. a select valve which is rotatably fitted to the body and the upper part of the fork bolt, has a dial externally fitted and fixed to the outer periphery of the upper end protruding from the fork bolt, and grips the rotation engagement part of the adjustment body at the lower part; A front fork damping force adjustment device comprising:
