PROBLEM TO BE SOLVED: To achieve improvement of strength and weight reduction in a wheel for a paddy field work machine.SOLUTION: A wheel of a paddy field work vehicle includes: an annular rim 21; and multiple spokes 23 radially extending from a center side of the annular shape of the rim 21 to the rim 21 and connected with the rim 21. Strength characteristics of the rim 21 and the spokes 23 are set so that entire parts of the rim 21 and the spokes 23 receive a load while avoiding local concentration of stress.SELECTED DRAWING: Figure 2
【課題】水田作業機用の車輪において、強度の向上及び軽量化を図る。【解決手段】円環状のリム21とリム21における円環の中心側からリムに向けて放射状に延び、且つ、リムに接続される複数のスポーク23とを備え、局部的な応力の集中を避けリム21及びスポーク23の全体で負荷を受けるように、リム21及びスポーク23の強度特性が設定されている。【選択図】図2
