ピード調整装置。 A valve chamber is formed in a body consisting of a cylinder cover or a valve housing of a switching valve for a cylinder, which is connected to an air port connected to a piping port on the outer surface of the body, and the valve chamber has both a variable throttle function and a non-return function. In a device that houses a regulating valve, an operating shaft that pivots the regulating valve on the body so as to be parallel to the hole axis of a port hole that serves as an outlet for air from the valve chamber when air is discharged from the cylinder side. a valve plate that is rotatably supported on the operating shaft and can be superimposed on the port hole; and the valve plate is attached to one axial direction of the operating shaft with the valve plate facing the opening surface of the port hole. The valve plate is made to overlap the port hole from one side edge by swinging the valve plate to one side about the operating shaft, and the opening degree of the port hole is sequentially adjusted. The speed adjustment of the air cylinder is characterized in that the valve plate has an inclined surface inclined toward the side edge and toward the opening surface on the side of the valve plate that does not oppose the opening surface.
