PROBLEM TO BE SOLVED: To achieve improvement of strength and weight reduction in a disk type wheel for a paddy field work machine.SOLUTION: A wheel for a paddy field work machine includes: a disk part 17 having a disk-like shape; and a ground part attached to an outer periphery part 21 of the disk part 17. The wheel includes multiple first protruding parts 22 which are molded radially along a radial direction of the disk part 17 so as to protrude from a surface of the disk part 17 between an axle connection part 19 and the outer periphery part 21 in the disk part 17.SELECTED DRAWING: Figure 3
