ことを特徴とする二輪車用フロントフオーク。 The inner tube is slidably inserted into the outer tube, a seat pipe is installed inside the outer tube, an oil reservoir is provided inside the seat pipe, and a suspension spring is interposed between the seat pipe and the outer tube. In the front fork for two-wheeled vehicles, a relief valve that opens against excess hydraulic oil flowing into the oil reservoir is installed inside the seat pipe, and a retainer that receives one end of the relief spring that biases the relief valve is installed in the axial direction. At the same time, a damping port is formed in the seat pipe to bypass this relief valve and allow excess hydraulic oil to flow in. A detection spring is interposed at the lower end of the suspension spring, and a detection spring is inserted between the two springs. and a transmission rod connected at one end to the detection sheet to drive the retainer, and the transmission rod is in sliding contact with the inner peripheral surface of the sheet pipe to adjust the opening area of the damping port. A front fork for two-wheeled vehicles that features connected valves.
