<p>PROBLEM TO BE SOLVED: To provide a pneumatic spring capable of eliminating a reinforcing piece near a mounting piece while forming the mounting piece in a body with an upper face plate.SOLUTION: There is provided an upper face plate 2 mounted to the vehicle body side of a railway vehicle. There is provided a lower member 3 mounted to the bogie side of the railway vehicle. There is provided a cylindrical diaphragm 4 fixed to the upper face plate 2 and the lower member 3. A circumferential edge part of the upper face plate 2 is bent to form a bent part 5. A mounting piece 6 fixed to the vehicle body is formed in a body with the upper face plate 2. The mounting piece 6 is formed at the circumferential edge of the upper face plate 2 and at a position different from that of the bent part 5. A cutout part is formed between the bent part 5 and the mounting piece 6. The bent part 5 is formed up to a location near the mounting piece 6. The upper face plate 2 is reinforced by the bent part 5 substantially over the entire circumference.</p> |
