| 摘要 | PURPOSE:To secure a wheel for farm use being lightweight, yet excellent in durability, by having the sectional form of a rim constituted of a thin plate member projectingly curved to the inner circumferential surface side. CONSTITUTION:A rim 2 is constituted of an almost C-shaped thin plate member projectingly curved to the inner circumferential surface side in its sectional form, which a rubber ring 6 is fitly engaged with a ring groove at the outer circumference side, and propulsive lugs 4 and 5 are solidly formed on this rubber ring 6. In addition, as for a spoke 3, the end part of its central side is coupled with a center boss 1 via a pair of coupling plates 7 and 7, while a spoke's outer end part 3a is made up in such a form that is broad in a direction of wheel rotation but narrow in a wheel shaft center direction and this outer end part 3a is coupled with the projectingly curved, inner circumferential surface of the rim 2 by way of setting end-to-end. | ||||||
