To provide an airless wheel which suppresses occurrence of slippage even on a soft ground without occurrence of puncture, and is excellent in running performance even on a road surface of a normal asphalt road.SOLUTION: An airless wheel comprises: a tread part 40 comprising plural transverse members 41 which are continuous in a direction crossing a circumferential direction of the wheel and are arranged in the circumferential direction, and connection parts 42 which respectively the transverse members 41 adjacent to each other in the circumferential direction; a pushing part 70 which is positioned on an inner peripheral surface side of the tread part 40, and is pushed toward a radial direction outer side along an inner peripheral curve surface of at least a part of the plural transverse members 41, thereby enabling increase in rigidity of the entire tread part 40; and a rigidity variable part 60 which can change rigidity of the entire tread part 40 by changing the pushing force of the pushing part 70 to the transverse member 41.SELECTED DRAWING: Figure 4
【課題】パンクすることなく、軟弱地盤でもスリップの発生を抑えるとともに、通常のアスファルト道路のような路面でも走行性能に優れたエアレス車輪を提供することを目的とする。【解決手段】車輪の円周方向と交差する方向に連続すると共に円周方向に並べられた複数の横部材41及び円周方向に互いに隣接する前記横部材41間をそれぞれ連結する連結部42を備えたトレッド部40と、前記トレッド部40の内周面側に位置して、複数の前記横部材41の少なくとも一部の内周曲面に沿って径方向外側に向かって押し当てられることで前記トレッド部40全体の剛性を高くすることが可能な押当部70と、前記押当部70の前記横部材41への押し当て力を変化させることで前記トレッド部40の全体の剛性を変化させることが可能な剛性可変部60とを備えた。【選択図】図4
