Title:
SHOCK ABSORBER AND METHOD FOR ATTACHING DAMPING FORCE ADJUSTMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/084846
Kind Code:
A1
Abstract:
Provided are: a shock absorber of which the degree of freedom in caulking a tubular body is enhanced; and a method for attaching a damping force adjustment device. A slit (weak section) is formed at an end section of a valve case (second tubular body) to reduce the stiffness of the end section of the valve case, and thus caulking is performed with a smaller caulking force, that is, the end section of the valve case can be bent with a smaller pressing force, thereby enhancing the degree of freedom in caulking the valve case (tubular body).
