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, the upper end of the piston rod is screwed onto a mounting portion 2a at the center inside of a cap member disposed at the upper end of the inner tube, and the upper end of the piston rod is screwed onto a threaded portion at the upper end of the piston rod. The upper end threaded portion of the lock nut that maintains the screwed state of the piston rod to the cap member is screwed together, and the lower end of the lock nut is screwed onto the lower end side of the lock nut. A front fork characterized in that the extending portion is formed in close contact with the outer periphery of the piston rod near the upper end thereof. (2) Inside the piston rod near its lower end, there is a control valve that allows changing a predetermined damping force generated when the piston part disposed at the lower end of the piston rod slides inside the cylinder, and
The front according to claim 1, wherein the control rod has a lower end connected to the control valve and an upper end disposed inside the upper end of the piston rod, at the axial center of the piston rod. Folk. (3) Request for registration of a utility model in which a control rod inserted through the shaft of a piston rod is configured to move up and down within the piston rod by operating from the outside of the upper end of the inner tube, thereby moving the control valve up and down. The front fork described in item 1.
