Title:
DAMPING FORCE-ADJUSTING SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2017/145983
Kind Code:
A1
Abstract:
Provided is a damping force-adjusting shock absorber with which stable damping force is obtained even in an ultra-low piston speed range. A second valve body 82 with a smaller diameter than a first valve body 81 is interposed between the first valve body 81 and subvalve bodies. It is thereby possible to reduce the area of contact between a main valve body (second valve body 82) and a subvalve body (second disc 84) when the main valve bodies (first valve body 81 and second valve body 82) are opened. As a result, it is possible to inhibit sticking between the main valve bodies and the subvalve bodies and obtain a stable damping force.
