<p>The invention relates to the field of shock absorbers. There is disclosed an outer shell (64) which is light-weight and thin-walled throughout the overall length thereof, the rigidity of the portion of the outer shell which should have a high rigidity being enhanced sufficiently by a double pipe structure using a bottomed cylinder (10A). The shock absorber of the invention is provided with a piston (2) which has a damping force generating mechanism and which partitions the interior of a cyliner into a rod-side chamber (3) and a piston-side chamber (4); a piston rod (5) with the piston mounted thereto, the piston rod being moveable into and out of the cylinder; a base valve (8) provided at an open end of the piston-side chamber in the cylinder; and an outer shell (6A) 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 (11), and a bottomed cylinder (10A) having a cylindrical portion (10B) which cooperates with the thin-walled outer shell and is fitted in the lower end portion of the outer shell along the inner periphery thereof. In this state, the bottomed cylinder (10A) is welded (12A) to the outer shell and the knuckle bracket. <IMAGE></p> |
