PROBLEM TO BE SOLVED: To provide an attenuation valve which can effectively improve a riding comfort of a two-wheel vehicle, and a shock absorber having the attenuation valve.SOLUTION: This attenuation valve V comprises: a valve disc 2 having an elongation-sided passage 3 and a compression-side passage 4 for making an elongation-side chamber R1 and a compression-side chamber R2 in a shock absorber D communicate with each other; an elongation-side valve body 5 for imparting resistance to a flow of fluid progressing toward the compression-side chamber R2 from the elongation-side chamber R1; a compression-side valve body 9 for imparting resistance to a flow of fluid progressing toward the elongation-side chamber R1 from the compression-side chamber R2; an elongation-side spring 32 for exerting an energization force for energizing the elongation-side valve body 5; a compression-side spring 35 for exerting an energization force for energizing the compression-side valve body 9; and an attenuation force adjustment part 11 which can change the energization forces of the elongation-side spring 32 and the compression-side spring 35.SELECTED DRAWING: Figure 2
【課題】二輪車における乗り心地を効果的に向上可能な減衰弁およびこの減衰弁を備えた緩衝器の提供である。【解決手段】本発明の減衰弁Vは、緩衝器Dにおける伸側室R1と圧側室R2を連通する伸側通路3と圧側通路4とを有するバルブディスク2と、伸側室R1から圧側室R2へ向かう流体の流れに抵抗を与える伸側弁体5と、圧側室R2から伸側室R1へ向かう流体の流れに抵抗を与える圧側弁体9と、伸側弁体5を附勢する附勢力を発揮する伸側ばね32と、圧側弁体9を附勢する附勢力を発揮する圧側ばね35と、伸側ばね32と圧側ばね35の附勢力を変更可能な減衰力調整部11を備えて構成されている。【選択図】図2
