To provide an air spring for railway rolling stock surely and stably exhibiting the initial performance with interposition of a mesh-like fiber for a long term by minimizing rolling phenomenon of the mesh-like fiber, thereby further improving durability.

In the air spring for railway rolling stock with a diaphragm 3 made of an elastic material extended between an upper support section 1 on a vehicle body side and a lower support section 2 on a bogie side underlying the upper support section, an upper receiving seat 1d made of rubber is disposed on a lower surface side of the upper support section 1; a sliding plate 21 made of metal or a synthetic resin is attached to a portion 1K for receiving the diaphragm 3 in the upper receiving seat 1d; the mesh-like fiber 22 is interposed between the sliding plate 21 and the diaphragm 3; and a modified silicone resin is applied to the mesh-like fiber 22.
