Abstract

The present invention provides a non-pneumatic tire which is provided with an attachment body (11) attached to an axle, a ring-shaped body (13) which surrounds the attachment body (11) from the outside in a tire radial direction, and a coupling member (15) which displaceably couples the attachment body (11) and the ring-shaped body (13), wherein the coupling member (15) is formed of a synthetic resin material and a reinforcing member is embedded in the coupling member (15).

First claim

The invention claimed is:

1. A non-pneumatic tire comprising:
an attachment body attached to an axle;
a ring-shaped body which surrounds the attachment body from the outside in a tire radial direction; and
a coupling member which displaceably couples the attachment body and the ring-shaped body,
wherein the coupling member is formed of a synthetic resin material and includes a reinforcing member made of metal embedded therein, and
the reinforcing member is formed to follow side edges of the coupling member along an extending direction of the coupling member.

2. The non-pneumatic tire according to claim 1 , wherein:
the coupling member includes an elastic coupling plate whose opposite end portions are respectively coupled to the attachment body and the ring-shaped body;
a curved portion curved in a tire circumferential direction is formed in the elastic coupling plate; and
the reinforcing member is embedded at least in the curved portion in the elastic coupling plate.

3. The non-pneumatic tire according to claim 2 , wherein a through hole into which the synthetic resin material enters and is fixed to is formed in the reinforcing member.

4. The non-pneumatic tire according to claim 2 , wherein:
a portion of the attachment body to which at least the coupling member is coupled, the ring-shaped body, and the coupling member are integrally formed of a synthetic resin material; and
an end portion of the reinforcing member reaches the inside of at least one of the attachment body and the ring-shaped body.

5. The non-pneumatic tire according to claim 4 , wherein a through hole into which the synthetic resin material enters and is fixed to is formed in the reinforcing member.

6. The non-pneumatic tire according to claim 1 , wherein:
a portion of the attachment body to which at least the coupling member is coupled, the ring-shaped body, and the coupling member are integrally formed of a synthetic resin material; and
an end portion of the reinforcing member reaches the inside of at least one of the attachment body and the ring-shaped body.

7. The non-pneumatic tire according to claim 6 , wherein a through hole into which the synthetic resin material enters and is fixed to is formed in the reinforcing member.

8. The non-pneumatic tire according to claim 1 , wherein a through hole into which the synthetic resin material enters and is fixed to is formed in the reinforcing member.
