<p>PROBLEM TO BE SOLVED: To provide an upright type grease slide front fork capable of improving responsibility of guide bushings.SOLUTION: This invention relates to an upright type grease slide front fork 1 in which a part of an inner tube 3 at a vehicle body side is inserted from above into an inside part of a vehicle axle side outer tube and the inner tube 3 is supported by guide bushings fitted to an upper part and a lower part of an inner circumference of the outer tube in such a way that it can be slid upwardly and downwardly, the inner tube 3 is fixed to the vehicle body by a split bracket 6 fixed to the outer circumference at its upper end and an attenuation force is generated by a frictional resistance between the guide bushings and the inner tube 3 that are slid and contacted to each other through grease. The upper end part of the inner tube 3 is formed with a maze aspiration communication passage 10 and the inner side of the inner tube 3 is communicated with the surrounding atmosphere through the aspiration communication passage 10.</p> |
