<P>PROBLEM TO BE SOLVED: To provide an air spring with a stopper improved to easily make a height adjustment of the stopper caused by a height adjustment by air supply-exhaust to a diaphragm, more than a conventional height adjustment. <P>SOLUTION: The air spring A with the stopper includes: an air spring part (a) constituted of an outer cylinder 1, an inner cylinder 2 and a rubber diaphragm 3 ranging over both 1 and 2; an elastic part (b) below the air spring part (a); and a descent regulating means S arranged to make an upper stop member 5 and lower stop members 2 abut on each other for preventing excessive compression of the diaphragm 3. A height adjusting device T is constituted by supporting the three lower stop members 12 by the inner cylinder 2 to be movable in the radial direction and forming the upper stop member 5 in a ring body having a thin inner diameter part 5A and a thick outer diameter part 5B, and an operation mechanism B is equipped for performing height adjusting operation from the outside of the diaphragm 3, for rocking and moving the lower stop members 12 over a first stopper position (t) in which the lower stop members abut on the inner diameter part 5A and a second stopper position (j) in which the lower stop members 12 abut on the outer diameter part 5B. <P>COPYRIGHT: (C)2012,JPO&INPIT |
