摘要： Provided is a wheel (6a) in which a disk (62) includes a ring-shaped rim (60) on which a tire (6b) is fitted, and a disk (62) having a flat circular shape and disposed on an inner circumference of the rim (60). The disk (62) includes a first rib (62a) and a second rib (62b) which extend in a radial direction of the disk (62). A width of each of the first rib (62a) and the second rib (62b) in a circumferential direction of the disk (62) increases toward an outer circumferential side of the disk (62).

摘要： Provided is a wheel (6a) in which a disk (62) includes a first rib (62a) extending in a radial direction, and protruding out on one side in a direction of a central axis a1. A hub (61) of the wheel (6a) includes a first blade portion (61d1) extending in the radial direction. At least one of a pair of side surfaces of the first rib (62a) is inclined relative to a plane including the central axis a1 of the disk (62), and the first blade portion (61d1) is fixed to the inclined side surface on one side of the central axis a1.

摘要： Provided is a wheel which is inexpensive, light, and sufficiently rigid. A wheel 6a includes an annular rim 60 to which a tire 6b is externally fitted, a hub 61 which is arranged at a center portion of the rim 60 and to which an axle is connected, and a disk 62 which is attached with the rim 60 at a periphery portion and which covers one side of the wheel 6a. The disk 62 includes a planar portion 62a and a first rib 62b provided at a surface of one side of the planar portion 62a and extending in the radial direction. The planar portion 62a is provided with a first groove 62d at a surface of the other side at a position corresponding to the first rib 62b.
