Abstract: 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.

Abstract: Provided is a hand rim which is not slippery even when the surface is wet. A hand rim 7 includes a base material 70 and an anti-slippage layer 71 formed on the surface of the base material 70. The anti-slippage layer 71 includes an adhesive layer 71a formed on the surface of the base material 70 and particles 71b which are fixed through the adhesive layer 71a. The particles 71b are fixed so as to protrude from the adhesive layer 71a.
