| 摘要 | PURPOSE:To improve sinking control action and action of propelling power, by forming a shape of the side of a treadle into a protruded arc state part overhanging by facing outward of an annular ring. CONSTITUTION:A shape of the side of a treadle 5 is formed into a protruded arc state part 6 overhanging by facing outward of an annular ring 4. With this construction, sinking control action and propelling power action to be generated effectively by each of the treadles 5 are generated on the treadle at any position, therefore, a difference between the above two actions do vary drastically, the balanced two actions are done and stabilized smooth running can be done. Resistance when the treadle 5 sinks into wet rice field is a little. Paddling propelling power to be made along with a bottom board is increased by front hollow arc state part 11 and the above two actions are improved further by holding action of mud through actions of the front hollow arc state part 11 and a rear hollow arc state part 13. | ||||||
