Claims

[Claims for Utility Model Registration] (1) The upper end of the inner tube is connected to the upper end of the inner tube whose lower end is inserted into the outer tube, and the lower end thereof is connected to the upper end of the cylinder that stands up from the inner bottom of the outer tube. In a front fork having a piston rod that is inserted through the piston rod, a predetermined damping force that is generated when a piston portion disposed at the lower end of the piston rod slides inside the cylinder can be changed inside the vicinity of the lower end of the piston rod. The piston rod has a control valve, and the piston rod has a control rod whose lower end is connected to the control valve and whose upper end is disposed inside the upper end of the piston rod, and The upper end of the piston rod is screwed onto a cap member disposed at the upper end of the inner tube, and a bushing member is press-fitted between the inner circumference of the upper end of the piston rod and the outer circumference of the upper end of the control rod opposing thereto. The front fork is characterized by being made. (2) The control rod consists of a short slide pin part and a long slide rod part, and
A front fork according to claim 1, wherein the bushing member is press-fitted between the outer circumference of the slide pin portion and the inner circumference of the piston rod, or between the outer circumference of the slide rod portion and the inner circumference of the piston rod. (3) The front fork according to claim 1, wherein the control rod is formed to move up and down inside the piston rod and move the control valve up and down by operation from the outside of the upper end of the inner tube. .
