<P>PROBLEM TO BE SOLVED: To provide a cover body structure requiring less tightening force when a cover body is opened and closed, a liquid supply device with the structure, and a liquid fuel combustion device. <P>SOLUTION: This cover body structure comprises an oil supply tank stored in an oil fan heater, a cylindrical ferrule 20 formed at the upper part of the oil supply tank to flow fuel, and the cover body 30 opening and closing the ferrule 20. The cover body 30 is opened and closed by the rotating motion of the ferrule 20 about the vertical centerline direction and the rotating motion thereof about the horizontal peripheral direction. Since the cover body 30 is opened and closed by two-stage operation formed of the rotating motion of the ferrule 20 in the vertical direction and the rotating motion thereof in the circumferential direction, the cover body 30 is prevented from coming off or fuel is prevented from flowing out when the oil supply tank is turned over. <P>COPYRIGHT: (C)2004,JPO |
