Title:
SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2018/021125
Kind Code:
A1
Abstract:
Provided is a shock absorber with which variation in the generated damping force can be suppressed. This shock absorber 1 has an inner cylinder 6, a piston 11, and damping force generation mechanisms 15 and 16. The piston 11 has a piston main body 12, and a retainer 13 assembled in abutment with the piston main body 12. The piston main body 12 has an annular first seat part 12E, and the retainer 13 has an annular second seat part 13C that is connected in abutment with the first seat part 12E. The second seat part 13C has an outer circumferential tapered part 13C1 and an inner circumferential tapered part 13C2 that protrude in a tapered shape toward the first seat part 12E prior to assembly of the piston main body 12 and the retainer 13, and the inclination of the inner circumferential tapered part 13C2 is more gradual than the inclination of the outer circumferential tapered part 13C1.
