PURPOSE:To enable stable transmission of power irrespective of vertical movement of a driven pulley, by a method wherein a flat part is attached to the forward end of a polyvinyl V-belt, and is engaged with a driven pulley having a flat surface and width wider than that of the polyvinyl V-belt. CONSTITUTION:A V-groove 7a, engaging with a polyvinyl V-belt 8, is formed in a motor pulley 7, and a flat part 8a is attached to the forward end of the polyvinyl V-belt 8. A flat part 5a having a width a is formed on a driven pulley 5, while providing a gap C wider than width B of the polyvinyl V-belt 8. This normally keeps the polyvinyl V-belt 8 in a parallel state even if the driven pulley 5 is displaced downward due to deformation of a washing tank 2, enabling stable transmission of a power. |
