Abstract

The present disclosure includes a main body outer end which is an outer end of the rim body in the axial direction, a portion of the rim composed of a portion axially outer than the main body outer end, and a ring-shaped portion located on the innermost radial direction of the inner peripheral surface of the rim outer end portion is a rim inner peripheral end, the wall portion, so as to become a wall with respect to the air flowing axially outward along the inner peripheral surface of the rim body, the air hole and the axial direction overlapping portion of the rim inner peripheral end, an opposed portion arranged axially outward spaced apart from each other in the axial direction, extending radially outward from the opposing portion, so as to form one or more openings radially outward from the rim inner peripheral end, and an outer peripheral portion defining at least a portion of the opening.

Claims8

Dependent claims

A vehicle wheel comprising:

a cylindrical rim;
a disk including a central connection portion connected to a vehicle body, and a plurality of spokes arranged to connect the rim and the central connection portion;
and
a wall portion disposed so as to partially close a plurality of air holes provided between the spokes, wherein
when a radial direction of the rim is defined as a radial direction, a direction parallel to a rotation axis of the rim is defined as an axial direction, a direction away from a vehicle body center line in the axial direction is defined as an axially outward direction, and a direction toward the vehicle body center line in the axial direction is defined as an axially inward direction, the rim includes
a cylindrical rim body,
a ring-shaped spoke connection portion extending axially outward and radially outward from an axially outer end portion of the rim body, the spokes being connected to the spoke connection portion,
a ring-shaped outer rim flange connected to an axially outer end portion of the spoke connection portion, and
a ring-shaped inner rim flange connected to an axially inner end portion of the rim body for holding a tire together with the outer rim flange, and
when a portion composed of a body outer end that is an axially outer end of the rim body and a portion axially outward of the body outer end of the rim is defined as a rim outer end portion, and a ring-shaped portion located on the radially innermost side of an inner peripheral surface of the rim outer end portion is defined as a rim inner peripheral end, the wall portion includes
a facing portion provided so as to be spaced apart in the axially outward direction from a portion of the rim inner peripheral end that overlaps the air hole in the axial direction, the facing portion provided to face the portion in the axial direction, so as to serve as a wall with respect to air flowing axially outward along an inner peripheral surface of the rim body, and
an outer peripheral portion extending radially outward from the facing portion and defining at least a part of one or more openings communicating an inside and an outside of the wall portion in the axial direction, so as to provide the one or more openings radially outward from the rim inner peripheral end.
