AIR SPRING

摘要

An air spring according to this invention enables easy and reliable adjustment of a space between stoppers. Specifically, an upper member (3) and a lower member (4) are secured to upper and lower ends of a bellows (2). Stopper faces (5) and (6) that come in contact with each other to limit the amount of displacement of the upper member (3) are formed on the upper member (3) and the lower member (4). A movable body (7) that can move vertically to adjust the height of the stopper face (6) is provided in the lower member (4). A holding body (8) is provided that holds the movable body (7) in a manner that enables vertical movement thereof. The movable body (7) is capable of relative rotation around a central axis (18) with respect to the holding body (8). On at least one of the movable body (7) and the holding body (8), tapers (32) and (41) are formed that are capable of sliding with respect to the other of the movable body (7) and the holding body (8). The movable body (7) is rotated relative to the holding body (8) to cause the tapers (32) and (41) to slide and thereby move the movable body (7) upward or downward.
