する倒立型フロントフオーク。 An outer tube is supported by the vehicle body via a steering bracket, an inner tube is slidably fitted into the outer tube from below, a piston slides inside the inner tube to generate damping force, and the piston is connected to the outer tube. In an inverted front fork having a piston rod that supports the tube from the top and a suspension spring that elastically supports the inner tube toward the outer tube, an upper oil chamber above the piston and a lower oil chamber below the piston are communicated with each other. a detection spring that penetrates the piston rod and piston to form a hydraulic oil passage that allows a portion of the hydraulic oil to flow between the two oil chambers, and that is connected in series with the suspension spring by sandwiching a spring seat; An inverted front fork characterized by being equipped with an adjustment valve mechanism that reduces the opening area of a hydraulic oil passage in conjunction with the displacement of a spring seat during compression operation.
