"Fig." is corrected.

Claims

[Claims for Utility Model Registration] (1) The extension of the inner tube is housed between an inner tube slidably inserted into the outer tube and a cylinder erected from the inner bottom of the outer tube. In a front fork having a buffer spring that regulates the stroke end position during the side stroke, the upper end of the buffer spring is a cylinder that allows the lower end of the suspension spring to come into contact with the upper end at the stroke end of the extension stroke of the inner tube. 1. A front fork, characterized in that the front fork is formed so as to come into contact with a stopper member disposed on the outer periphery near the upper end thereof so as to be movable up and down. (2) The front fork according to claim 1, wherein the stopper member is formed to move up and down by external rotation of the inner tube. (3) The front fork according to claim 1, wherein the lower end of the buffer spring is fixed to the inner periphery of the lower end of the guide member which is housed in the inner periphery of the inner tube and fixed to the piston part. . (4) Utility model registration claim 1, in which the stopper member is formed to be locked to the upper end guide portion of the guide member that is housed on the inner circumferential side of the inner tube and fixed to the piston portion. Front fork as described. (5) The front fork according to claim 1, wherein the stopper member is connected to a cam member rotatably interposed on the outer circumference near the upper end of the cylinder. (6) The front fork according to claim 1, wherein the stopper member is a nut-shaped body screwed onto the outer periphery near the upper end of the cylinder.
