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 arranged vertically movably on the outer periphery near the upper end of the cylinder at the end of the stroke of the extension stroke of the inner tube. The stopper member is formed to be in contact with the lower end side of the stopper member, and the lower end of a suspension spring that biases the inner tube in the expansion direction is in contact with the upper end side of the stopper member. Front fork. (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 a nut-shaped body screwed onto the outer periphery near the upper end of the cylinder.
