PROBLEM TO BE SOLVED: To provide a wheel that is inexpensive, has sufficient rigidity and is light in weight.SOLUTION: A wheel 6a includes: an annular rim 60 to which a tire 6b is externally fitted; a hub 61 which is disposed in the central part of the rim 60 and to which an axle is coupled; and a disk 62 to the peripheral edge part of which the rim 60 is attached and which covers one side of the wheel 6a. The disk 62 has a plate-like part 62a, and a first rib 62b provided at the face of one side of the plate-like part 62a and extending in a radial direction. The plate-like part 62a is provided with a first groove 62d at the position corresponding to the first rib 62b of the face of the other side.SELECTED DRAWING: Figure 4
