FIXING STRUCTURE OF DIAPHRAGM

PROBLEM TO BE SOLVED: To provide a damper with an air spring, which facilitates confirmation of the aged deterioration in the damper. SOLUTION: This fixing structure of a diaphragm 6 fastens and fixes a diaphragm 6 in an air spring S including: a cylindrical air chamber 5; a cylindrical piston pipe 4 capable of entering the air chamber 5; and a cylindrical diaphragm 6 fitted in a folded state to the air chamber 5 and the piston pipe 4 to partition an air chamber G to the outer periphery of the piston pie 4 by a fixing ring 1. The fixing ring 1 includes: a ring body which is annular and tenses the diaphragm 6; and a hook part 11 caught in the tube end 4b of the piston pipe 4 to locate the ring body 10 in a position opposite to the outer periphery of the piston pipe 4.
