ABSTRACT:
The shock absorber of the present invention is provided with a piston which has a damping force generating mechanism and which partitions the interior of a cylinder into a rod-side chamber and a piston-side chamber; a piston rod with the piston mounted thereto, the piston rod being moved into and out of the cylinder, a base valve provided at an open end of the piston-side chamber in the cylinder; and an outer shell having a constant wall thickness throughout the overall length thereof and enclosing the outside of the cylinder to form a reservoir chamber. The outer periphery of a lower end portion of the outer shell is supported by a knuckle bracket, and a bottomed cylinder, having a cylindrical portion which cooperates with the thin-walled outer shell, is fitted in the lower end portion of the outer shell along the inner periphery thereof. In this state, the bottomed cylinder is welded together with the outer shell and the knuckle bracket.
