求の範囲第１項記載のフロントフオーク。[Scope of Claim for Utility Model Registration] (1) An inner tube is slidably inserted into an outer tube, a damper cylinder is erected at the center of the lower part of the outer tube, and a piston with a damping force generating mechanism is installed in the damper cylinder. In a front fork with a built-in damper, through which a piston rod is movably inserted, a hollow oil hole is erected at the bottom of the outer tube, and the oil hole is inserted along the axial direction between the inner circumference of the oil hole and the outer circumference of the damper cylinder. A front fork that forms a passage and divides an oil chamber for an oil lock between the outer circumference of the oil hole rod and the inner circumference of the outer tube. (2) The front fork according to claim 1, wherein the upper part of the passage opens into the reservoir and the lower part communicates with a compression valve for generating compression damping force. (3) The front fork according to claim 1, wherein the suction passage leading to the oil chamber of the damper cylinder branches from the passage, and a check valve is provided in the middle of the suction passage so as to be openable and closable.
