PROBLEM TO BE SOLVED: To provide a wheel capable of simply coping with puncture of a tire, and making it difficult to change the state of a flat tire from the state before the puncture.;SOLUTION: In this structure, a wheel rim has a penetration part in a direction connecting tires on both sides with a ground portion of the wheel rim, or a penetration part opened in a perimeter direction of the wheel rim and in a direction connecting the tires on both sides with a ground portion of the wheel rim. A tube to be swollen at atmospheric pressure different from that of the tire, a valve device comprising a plurality of valves, and interior materials are inserted in a space surrounded by the tire and the wheel from the penetration part. A supporting structure for isolation is installed between the tube and the tire and a portion for fixing the interior materials is installed, in the space surrounded by the tire and the wheel rim. An indicator capable of visually recognizing a proper atmospheric pressure of the tire at the wheel is provided. These invention can be individually used at will.;COPYRIGHT: (C)2004,JPO
