Title:
ROD ASSEMBLY AND SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2022/270326
Kind Code:
A1
Abstract:
In the present invention, a welded portion (second fastening portion) that is welded to a shaft end portion of a rod main body part (rod-shaped part) is formed at a position separated from a seating portion of a mounting eye (bracket) in the axial direction, so that the thermal effects of the welding on the seating portion of the mounting eye on which a flange part of a piston rod is seated is suppressed. Thus, it is possible to prevent the thermal effects of the welding from releasing axial force produced by screw fastening between a small-diameter portion of the piston rod and a shaft hole (first fastening portion) of a cylindrical part of the mounting eye.
