Abstract: Provided is a food stir-frying machine that makes it possible to surely and smoothly rotate a stirrer while bringing the stirrer into elastic contact with the inner surface of a pan, and increase the durability of the stirrer. A stirring device has: a supporting member that supports a rotary shaft; a stirring frame that supports the supporting member through a horizontal shaft in a direction in which a stirrer is moved in or out of a pan; and a device frame that vertically swingably supports the stirring frame in order to evacuate the stirrer upward, and between the stirring frame and the supporting member, biasing means adapted to bias the supporting member toward the pan side so as to bring the stirrer into contact with the inner surface of the pan.
