PROBLEM TO BE SOLVED: To obtain wheels which are extended at the time of being accelerated or operated at high speeds by stretching and connecting the first hub and the second hub between the first hub and the second hub and providing webs with a center part which is movable outward from an axle shaft according to centrifugal force generated by the rotation of a wheel assembled body. SOLUTION: A vehicle 20 comprises front wheels 28 and rear wheel assembled bodies 30, and the wheel assembled bodies 28 and 30 are provided with the same constituent members. The second adjacent sliding hub assembled body 70 provided with an inner hub 72 and an outer hub 74 located between the adjacent end part of an axle shaft 34 and a fixed hub assembled body 56 is movable between the adjacent end part of the axle shaft 34 and the fixed hub assembled body 56. A plurality of elastic webs 90 are provided between the fixed hub assembled body 56 and the sliding hub assembled hub 70. The webs 70 experience centrifugal force which moves the webs 90 outward at the time when the wheel assembled body 30 is rotated, and the center part of the webs 90 moves outward from the axle shaft 34 to extend the diameter of the wheel assembled body 30. |
