PROBLEM TO BE SOLVED: To provide an exhaust port cover capable of easily changing a state of a cover without demounting the cover in each discharging of exhaust heat. SOLUTION: This exhaust port cover 1 composed of a mounting tool 10 and a cover body 20 is disposed around an exhaust port 61. The cover body 20 is constituted slidably in the circumferential direction of an engagement section 13 on a shaft center of a first edge winding section 22. When a position of the center of gravity of the cover body 20 is positioned at a side of the exhaust port 61 with respect to a vertical face 30 passing through the shaft center of the first edge winding section 22, the cover body 20 is stabilized on the position at the exhaust port 61 side. When the position of the center of gravity of the cover body 20 is positioned at a side of a trivet 59 with respect to the vertical face 30, the cover body 20 is stabilized on the position at the trivet 59 side. Thus a covering state of the exhaust port 61 and an opening state of an upper part of the exhaust port 61 can be easily switched without demounting the exhaust port cover 1.
