オーク。 The vehicle body side tube and the wheel side tube are slidably fitted together, the damper cylinder is erected at the center of the inside of the wheel side tube, and the piston rod, which is slidably inserted into the damper cylinder via the piston, is inserted into the vehicle body side tube. In the connected front fork, a hollow spring seat is erected above the damper cylinder, and the spring seat partitions an upper oil storage chamber and a lower pressure chamber in the tube on the side of the vehicle, and is inserted through a through hole in the body. An opening/closing member that also serves as an oil lock piece that can slide up and down is inserted into the spring seat through the oil storage chamber and pressure chamber, and a suspension spring is interposed between the opening/closing member and the tube on the vehicle body side. A piston portion with a valve is provided on the outer periphery of the piston rod, a detection spring is interposed between the piston portion and a seat provided on the opening/closing member, and an oil lock piece is further provided on the outer periphery of the piston rod facing the hollow portion of the opening/closing member. A front fork with a built-in damper.
