<P>PROBLEM TO BE SOLVED: To prevent a regulation structure which regulates a length at the longest elongation time from impairing slide performance between an outer tube and an inner tube. <P>SOLUTION: This front fork has: a slide metal M in which the regulation structure for regulating a protrusion position at a time when the inner tube 2 inserted into the outer tube 1 so as to be capable of entering thereto and exiting therefrom is protruded most from the inside of the outer tube 1 is arranged between the outer tube 1 and the inner tube 2; a slide part M1 which has stopper members 11, 21 capable of abutting on the slide metal M, and in which the slide metal M is slidably contacts with the external periphery of the inner tube 2 or the internal periphery of the outer tube 1; and an abutting end M2 which makes the stopper member abut on each other. The front fork also has a gap b between the external periphery of the inner tube opposing the internal periphery side or the external peripheral side of the abutting end M2 or the internal periphery of the outer tube and itself. <P>COPYRIGHT: (C)2012,JPO&INPIT |
