。 ヨツクアブソーバ。(1) An inner cylinder filled with oil and an outer cylinder that communicates with the inside of the inner cylinder through the lower end of the inner cylinder and stores the inner cylinder with a gap are fixed to the axle side, and the inner cylinder is reciprocated. A moving piston is fixed to the vehicle body via a rod, and a cover with an opening at the lower end that covers the upper circumferential surface of the outer cylinder is fixed to the rod with a gap, so that the piston moves up and down in response to the reciprocating movement of the piston. In a shock absorber that suppresses vehicle body vibration by using the flow resistance of oil that alternately flows into the cylinder space, the outer diameter of the portion of the outer cylinder that does not overlap with the cover that moves up and down with the reciprocation of the piston is: A shell characterized in that the outer diameter is larger than the outer diameter of the outer cylinder portion that overlaps with the cover. Yotsuk absorber. （２）外筒のカバーと重ならない部位の外径がカバー外
