。[Scope of Claim for Utility Model Registration] (1) A piston with a rod is inserted into a pneumatic cylinder, a plug is provided near the piston, and this plug fits into a cushion seal on the inner periphery of a plug hole that also serves as an air passage. When the air passage between the pressure chamber and the air port is blocked, a bypass is provided that connects the pressurization chamber and the air port, and a throttle valve is provided that is urged into the bypass to resist the pressure in the bypass. A cushion device for a pneumatic cylinder, characterized in that the opening degree of a throttle valve increases when the inside of a pressure chamber is suddenly pressurized. (2) A cushion device for a pneumatic cylinder according to claim 1, wherein the plug is formed by a large diameter portion of a rod, and the plug hole is formed by a rod hole. (3) A cushion device for a pneumatic cylinder according to claim 1, wherein the throttle valve is formed by a pressure regulating plunger fitted into a cylinder facing the bypass. (4) A cushion device for a pneumatic cylinder according to claim 3, wherein the pressure regulating plunger is pushed toward the bypass side by the elasticity of a spring.
