ADJUSTMENT MECHANISM OF INITIAL SET LOAD IN SUSPENSION SPRING OF SHOCK ABSORBER

摘要

PROBLEM TO BE SOLVED: To provide a suspension spring adjustment mechanism of a shock absorber capable of preventing a rotation positioning mechanism from damaging a main body side screw part, simplifying adjustment work, grasping amount of adjustment clearly, and stabilizing spring characteristic.;SOLUTION: In this adjustment mechanism of a suspension spring 4 for adjusting initial set load of the suspension spring 4 by providing a spring seat 5 in the main body 1 side screw part 7 of the shock absorber and a spring adjuster 6 abutted on the spring seat 5, a groove 8 extending in the axial direction of a main body 1 is formed at the outer periphery of the screw part 7, this groove 8 and a protruding part 5A provided on the spring seat 5 fitted into the outer periphery of the screw part 7 so as to move freely in the axial direction of the main body 1 and carrying the suspension spring 4 are mutually engaged, the spring adjuster 6 screw-fitted into the screw part 7 rotatably is abutted on an anti-suspension spring side of the spring seat 5, and the rotation positioning mechanism A is provided between the spring seat 5 and the spring adjuster 6.;COPYRIGHT: (C)2007,JPO&INPIT
