Abstract

A spoke wheel includes a rim for supporting a tire having rim guards, a hub located radially inwardly with respect to the rim, and a plurality of spokes integrally connected with the rim and the hub at outer and inner ends, respectively, and extending radially with respect to the hub; a laterally outer surface of the outer end of each spoke and a laterally outer peripheral edge of the rim are located laterally inwardly with respect to a tip of a laterally outer rim guard; outer ends of main spokes among the spokes are provided with convex portions projecting laterally outwardly and extending in the radial direction, and a lateral position of a laterally outer tip of each convex portion lies in the range between a lateral position of the laterally outer peripheral edge of the rim and a lateral position of the tip of the laterally outer rim guard.

First claim

What is claimed is:

1. A spoke wheel comprising:
a rim for supporting a tire having rim guards;
a hub located radially inwardly with respect to the rim; and
a first plurality of spokes integrally connected with the rim and the hub at an outer end and an inner end, respectively, and extending radially with respect to the hub, laterally outer surfaces of the outer ends of the spokes and a laterally outer peripheral edge of the rim being located laterally inwardly with respect to a tip of a laterally outer rim guard,
wherein outer ends of a second plurality of spokes among the first plurality of spokes are provided with convex portions projecting laterally outwardly and extending in the radial direction, and
wherein lateral positions of laterally outer tips of the convex portions lie in a range between a lateral position of the laterally outer peripheral edge of the rim and a lateral position of the tip of the laterally outer rim guard.

2. The spoke wheel according to claim 1 , wherein lateral positions of the laterally outer tips of the convex portions are the same as the lateral position of the tip of the laterally outer rim guard.

3. The spoke wheel according to claim 1 , wherein a radially inner end portion of each convex portion has an inclined surface whose protrusion height decreases toward the radially inward direction.

4. The spoke wheel according to claim 1 , wherein each convex portion extends outward to the laterally outer peripheral edge of the rim.

5. The spoke wheel according to claim 1 , wherein the laterally outer tip of each convex portion is in a plane shape perpendicular to a rotation axis of the wheel.

6. The spoke wheel according to claim 1 , wherein the second plurality of spokes have a larger circumferential width than spokes other than the second plurality of spokes.

7. The spoke wheel according to claim 1 , wherein the second plurality of spokes are the same as the first plurality of spokes, and the convex portions are provided on the outer ends of all the spokes.
