Abstract: A splash guard mechanism for preventing the entry of grass, in addition to mud and gravel, in a vehicle such as a an ATV (All Terrain Vehicle). A disc-shaped splash guard mechanism covers a brake disc stored in a concave portion of a wheel to thereby prevent the entry of dirt such as mud, gravel, and grass into the brake disc. If the dirt enters the brake disc, the dirt is ejected from a first cutout portion provided on a lower portion of the splash guard mechanism. Additionally, a grass removal portion substantially triangle-shaped in plan view is provided on a lower portion of the splash guard mechanism. The grass removal portion protrudes toward a vehicle center to push grass on the ground outward and away from the first cutout portion. Since the grass is only pushed out, the grass is prevented from being cut and entering the brake disk.

Abstract: A wheel for a vehicle which is excellent in appearance quality, is light, and has stiffness. In the wheel for the vehicle having a rim section which has a substantially cylindrical shape and into which a tire is fit, and a disk section having a substantially disk shape and bonded to the inside of the rim section, the rim section includes a rim body part and a rim flange part, the rim body part is formed such that the thickness of a part to which the disk section is bonded is thicker than the thicknesses of the other parts, and the rim flange part is formed by bending both thin end parts of the rim body part into a hollow shape.

Abstract: To make it possible to fit a vibration-proofing member into a hollow pipe, without impairing the appearance and without increasing the number of component parts. A hollow pipe formed by extrusion of a light alloy is integrally provided on an inside surface thereof with a rib extending along the longitudinal direction of the hollow pipe. A vibration-proofing member for restraining vibration of the hollow pipe is inserted in the hollow pipe so that the rib holds a position thereof in the hollow pipe in a direction orthogonal to the longitudinal direction.
