Claims

[Scope of utility model registration request]

A wheel-side tube is slidably inserted into the vehicle-side tube, a damper cylinder stands up from the center of the wheel-side tube, a piston rod is movably inserted into the damper cylinder via a piston, and the piston rod is inserted into the vehicle-side tube. In the front fork, the suspension spring located at the top of the damper cylinder constantly biases the body side tube and piston rod in the direction of extension.
A hollow spacer is provided downward from the center of the upper end of the vehicle body side tube, and the spacer divides the reservoir in the vehicle body side tube into two chambers, and a slider is slidably inserted into the outer or inner periphery of the spacer. The slider supports the upper detection spring and is supported by a suspension spring, and the spacer is formed with a through hole that communicates the inside and outside chambers, and the opening degree of the through hole changes as the slider moves up and down. Front fork characterized by being made variable.
