[Technical Problems]To provide a simple structure with which traveling performance of a traveling machine body in a wet paddy can be improved.[Means of Solving the Problems]A work vehicle includes: traveling wheels 4 that supports a traveling machine body； and cage wheels 100 detachably attached to the traveling wheels 4. The cage wheels 100 each include: a rim section 102 having an annular shape； and a plurality of cage wheel lugs 105 provided to the rim section 102 at an appropriate interval along a circumference direction of the rim section 102. The cage wheel lug 105 is inclined to have an outer circumference side end portion 105a positioned more on an upstream side than an inner circumference side end portion 105c in a rotational direction when the traveling vehicle body travels forward, in side view. The outer circumference side end portion 105a of the cage wheel lug 105 is bended toward the rotational center of the rim section 102.本發明之課題，在於利用簡單之構成使移行機體之水田行走性能提升。作業車輛具備有：移行車輪，其支撐移行機體；及籠式車輪，其裝卸自如地被安裝於移行車輪。籠式車輪具備有：環狀之輪緣部；及複數個籠式車輪凸出部，其等係沿著輪緣部之圓周方向以適當間隔被設置於輪緣部。籠式車輪凸出部以於側視時外周側端部側位於較內周側端部側更靠移行機體之前進時之旋轉方向上游側的方式傾斜。籠式車輪凸出部之外周側端部朝向輪緣部之旋轉中心側彎曲。
