Abstract

PROBLEM TO BE SOLVED: To provide a wheel and a working vehicle capable of securely traveling on a soft ground without using an attachment such as an auxiliary wheel. SOLUTION: When a wheel main body 9 is driven for rotation in the condition that the wheel main body 9 is buried under the soil, a soil scraping member 12 projected from a side of the wheel main body 9 pushes the soil 11 backward in the rotating direction of the wheel main body 9. With this structure, since the propelling force by the wheel 4 is improved, generation of slip or the like is prevented, and the secure traveling on the soft ground 10 is realized.

When each of the soiling members 12 is in the overhanging posture S, it does not easily bend against an external force acting along the circumferential direction of the driving rear wheel 4. Therefore, in a state where the driving rear wheel 4 is buried in the soft ground 10, the soiling member 12 is moved to the overhanging posture S.
When the drive rear wheel 4 is rotationally driven to open, the soil removing member 12 pushes the soil 11 of the soft ground 10 backward in the rotation direction of the wheel body 9. This allows
When the wheel body 9 rotates, the driving resistance to the soft ground 10 increases, so that the propulsive force of the traveling vehicle body 2 by the driving wheels 4 increases, and the riding management device 1 does not slip and the like. The vehicle can travel on the soft ground 10 reliably.
