ーズダイブ装置。In a front fork consisting of a cylinder planted from the bottom of the outer tube and an inner tube slidably inserted into the gap between the outer tube and the cylinder, a hollow center bolt is screwed into the cylinder from the outside of the bottom of the outer tube. A hollow adjustment rod with a poppet valve at the tip is slidably inserted into the hollow interior of the center bolt, and a seat on which the poppet valve is seated is formed in the hollow interior of the adjustment rod. So that the poppet valve is pressed by the seat part and closes the pressure side hydraulic oil flow path formed between the center bolt and the adjustment rod.
A link means that senses braking torque is linked to the adjusting rod, and a bypass passage is provided through which hydraulic oil flows in the compression and rebound strokes through the hollow interior of the adjusting rod, and the throttle area can be varied within the hollow interior of the adjusting rod. An anti-nose dive device for a front fork, characterized in that a damping force adjusting rod is rotatably inserted into the front fork, and the damping force adjusting rod can be operated from the outside.
