込み防止機構を備えたフロントフオーク。 A fork pipe is slidably inserted into the bottom case, and a seat pipe installed at the bottom of the bottom case defines an inner oil chamber and an outer oil chamber, and an upper oil chamber is connected to the inner oil chamber above the seat pipe. In the front fork, the bottom case is equipped with a valve that prevents sinking by closing the oil passage that communicates the inner oil passage and the outer oil passage, and the inner circumferential surface of the bottom case and the outer circumferential surface of the fork pipe. An annular oil passage is formed between the outer oil chamber and the upper oil chamber, and a plurality of oil holes are formed in the fork pipe at a distance from each other in the vertical direction. A front fork equipped with a sinking prevention mechanism, characterized in that at least one of the oil holes is formed at a position opening into an outer oil chamber and the other one opening into an upper oil chamber.
