Abstract

A non-pneumatic tire has an inner annular body centered on a rotation axis portion, an outer annular body provided radially outward of the inner annular body, a wheel portion including a connecting member elastically deforming and for connecting the inner annular body and the outer annular body, and a tread portion provided radially outward of the outer annular body and in contact with a road. The non-pneumatic tire is provided with an electrode portion which is in contact with the tread portion and is provided on the radially inner side of tread portion, and a wiring portion which connects the electrode portion and the inner annular body and is formed of a conductor. A part of the wheel portion is formed of a nonmetallic material, and the electrode portion is formed of a conductor having a prescribed width in tire width direction and a prescribed length in tire circumferential direction.

First claim

The invention claimed is:

1. A non-pneumatic tire comprising:
a wheel portion including an inner annular body centered on a rotation axis portion, an outer annular body radially outward of the inner annular body, and a connecting member configured to elastically deform and connecting the inner annular body and the outer annular body;
a tread portion provided radially outward of the outer annular body and configured to be in contact with a road;
an electrode portion inside the tread portion, or in contact with and radially inside the tread portion; and
a wiring portion for connecting the electrode portion and the inner annular body and formed of a conductor, wherein
the electrode portion is annular extending along the tire circumferential direction,
at least a part of the wheel portion is formed of a non-metallic material, and
the electrode portion is formed of a conductor having a predetermined width in tire width direction, and having a predetermined length in tire circumferential direction.

2. The non-pneumatic tire according to claim 1 , wherein the electrode portion covers the entire width of the outer annular body in the tire width direction.

3. The non-pneumatic tire according to claim 2 , wherein the wiring portion is embedded in the wheel portion.

4. The non-pneumatic tire according to claim 2 , wherein a part of the tread portion and the electrode portion in the tire circumferential direction has a wider portion in the tire width direction than other portions.

5. The non-pneumatic tire according to claim 1 , wherein the electrode portion is a cord formed of a metal material and included in a spiral belt arranged along the tire circumferential direction, and
the wiring portion is connected to the cord.

6. The non-pneumatic tire according to claim 5 , wherein the wiring portion is embedded in the wheel portion.

7. The non-pneumatic tire according to claim 5 , wherein a part of the tread portion and the electrode portion in the tire circumferential direction has a wider portion in the tire width direction than other portions.

8. The non-pneumatic tire according to claim 1 , wherein the wiring portion is embedded in the wheel portion.

9. The non-pneumatic tire according to claim 8 , wherein a part of the tread portion and the electrode portion in the tire circumferential direction has a wider portion in the tire width direction than other portions.

10. The non-pneumatic tire according to claim 1 , wherein a part of the tread portion and the electrode portion in the tire circumferential direction has a wider portion in the tire width direction than other portions.

11. A non-pneumatic tire comprising:
a wheel portion including an inner annular body centered on a rotation axis portion, an outer annular body radially outward of the inner annular body, and a connecting member configured to elastically deform and connecting the inner annular body and the outer annular body;
a tread portion provided radially outward of the outer annular body and configured to be in contact with a road;
an electrode portion inside the tread portion, or in contact with and radially inside the tread portion; and
a wiring portion for connecting the electrode portion and the inner annular body and formed of a conductor, wherein
at least a part of the wheel portion is formed of a non-metallic material, and
the electrode portion is formed of a conductor having a predetermined width in tire width direction, and having a predetermined length in tire circumferential direction, wherein a part of the tread portion and the electrode portion in the tire circumferential direction has a wider portion in the tire width direction than other portions.
