PROBLEM TO BE SOLVED: To provide a work vehicle that is mounted with tires which can absorb vibration from the ground to improve riding comfort and can be reduced in weight.SOLUTION: In a work vehicle having a spraying device 11 mounted on a vehicle body 2 comprising front wheels 3 and rear wheels 4, the front wheels 3 and the rear wheels 4 comprise vehicle shafts 50 and 60, flanges 62, a plurality of spokes 64, rims 66 and tires 68. The tires 68 have: inner rubber filled layers 80 that contact the rims 66 and have rubber filled thereinto an outer rubber filled layers 82 that are positioned outside in a radial direction of the inner rubber filled layers 80 integrally with the inner rubber filled layers 80 and have rubber filled thereinto and air layers 84 provided between the inner rubber filled layers 80 and the outer rubber filled layers 82. The air layers 84 are provided consecutively or intermittently in an outer periphery direction of the rims 66. The air layers 84 between the inner rubber filled layers 80 and the outer rubber filled layers 82 can reduce vibration from the ground so as to improve riding comfort. Further the provision of the air layers 84 allows the tires 68 to be reduced in weight.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2016,JPO&INPIT【課題】地面からの振動を吸収して乗り心地を良くすると共に、軽量化が図れるタイヤを装備した作業車両の提供である。【解決手段】前輪3及び後輪4を備えた車体2に散布装置11を装着した作業車両において、前輪3及び後輪4は、車軸50,60と、フランジ62と、複数のスポーク64と、リム66と、タイヤ68とを備え、タイヤ68は、リム66に接して内部にゴムを充填した内側ゴム充填層80と、内側ゴム充填層80と一体で内側ゴム充填層80の径方向外側に位置し内部にゴムを充填した外側ゴム充填層82と、内側ゴム充填層80と外側ゴム充填層82との間に設けた空気層84とを有し、空気層84は、リム66の外周方向に沿って連続的又は断続的に設けられている。内側ゴム充填層80と外側ゴム充填層82との間の空気層84により地面からの振動が軽減されるため、乗り心地が向上する。また、空気層84を設けることでタイヤ68の軽量化が図れる。【選択図】図9
