An air supply pipe that sends air to the tip of the insertion part is connected to the cylinder, and a leak hole communicating with the atmosphere is bored in the piston, so that during standby, the air supplied from the air supply pipe to the cylinder leaks. In the air supply operation device for an endoscope, the air is released into the atmosphere through a hole, and when air is supplied, the air in the cylinder is sent to the air supply pipe by closing the leak hole, an upper air supply pipe. An inlet is formed in the side wall of the cylinder, an annular groove is formed on the outer periphery of the piston facing the inlet, and a communication hole is bored through which the bottom of the groove communicates with the leak hole. , a valve body made of an elastic body having a generally V-shaped cross section expanding outward and having an annular shape as a whole is crimped into the groove so as not to contact the inner wall of the cylinder; Endoscope air supply operation device.
