Abstract

A resin part for a vehicle includes a fender main body formed of a fiber-reinforced resin using a resin fiber, and a fastening section formed of the same resin material as the resin fiber, formed integrally with the fender main body and fastened to the vehicle body.

First claim

What is claimed is:

1. A resin part for a vehicle comprising:
a resin part main body formed of a fiber-reinforced resin material that comprises a matrix resin and a resin fiber; and
a fastening section extending from the resin part body and formed of the same material as the resin fiber, wherein the fastening section is formed integrally with the matrix resin.

2. The resin part for a vehicle according to claim 1 ,
wherein the matrix resin that has a melting point lower than that of the resin fiber.

3. The resin part for a vehicle according to claim 1 ,
wherein the fastening section is provided at least on the resin part main body at an outer side in the vehicle.

4. The resin part for a vehicle according to claim 1 ,
wherein the fastening section comprises an outer fastening section provided on the resin part main body at an outer side in the vehicle and an inner fastening section provided on the resin part main body at an inner side in the vehicle, and
the outer fastening section and inner fastening section face each other with the resin part main body being interposed therebetween in a thickness direction of the resin part main body.

5. The resin part for a vehicle according to claim 4 ,
wherein the fastening section comprises a hole inner circumference forming section formed along an inner circumferential edge portion of a fastening member insertion hole formed in the resin part main body, and
the outer fastening section and the inner fastening section are continuous integrally with each other via the hole inner circumference forming section and cover the inner circumferential edge portion of the fastening member insertion hole.

6. The resin part for a vehicle according to claim 1 , further comprising an outer fastening support section provided around the fastening section in the resin part main body at an outer side in the vehicle, formed of the same resin material as the resin fiber and formed integrally with the resin part main body,
wherein the outer fastening support section comprises an outer cutout section.

7. The resin part for a vehicle according to claim 1 , further comprising: an inner fastening support section provided around the fastening section in the resin part main body at an inner side in the vehicle, formed of the same resin material as the resin fiber and formed integrally with the resin part main body,
wherein the inner fastening support section comprises an inner cutout section.

8. The resin part for a vehicle according to claim 1 , further comprising: an outer fastening support section or an inner fastening support section that are provided around the fastening section in the resin part main body at an outer side or an inner side in the vehicle, respectively, that are formed of the same resin material as the resin fiber and that are formed integrally with the resin part main body,
wherein the outer fastening support section and the inner fastening support section are formed to be continuous with each other while being provided in an annular range that surrounds a fastening member insertion hole formed in the fiber-reinforced resin.

9. The resin part for a vehicle according to claim 1 , further comprising:
an outer fastening support section provided around the fastening section in the resin part main body at an outer side in the vehicle, formed of the same resin material as the resin fiber and formed integrally with the resin part main body; and
an inner fastening support section provided around the fastening section in the resin part main body at an inner side in the vehicle, formed of the same resin material as the resin fiber and formed integrally with the resin part main body,
wherein the outer fastening support section and the inner fastening support section are formed within an annular range that surrounds a fastening member insertion hole formed in the fiber-reinforced resin,
the outer fastening support section and the inner fastening support section respectively comprise an outer cutout section and an inner cutout section that avoid each other when seen in a thickness direction of the resin part main body, and
the outer cutout section and inner cutout section are disposed to be arranged alternately in a circumferential direction of the annular range when seen in the thickness direction of the resin part main body.

10. The resin part for a vehicle according to claim 1 , further comprising:
an outer fastening support section provided around the fastening section in the resin part main body at an outer side in the vehicle, formed of the same resin material as the resin fiber and formed integrally with the resin part main body; and
an inner fastening support section provided around the fastening section in the resin part main body at an inner side in the vehicle, formed of the same resin material as the resin fiber and formed integrally with the resin part main body,
wherein the outer fastening support section and the inner fastening support section are formed within an annular range that surrounds a fastening member insertion hole formed in the fiber-reinforced resin, and respectively comprise cutout sections at positions facing each other within an annular range while having the fiber-reinforced resin interposed therebetween.

11. A resin part for a vehicle comprising:
a resin part main body formed of a fiber-reinforced resin using a resin fiber; and
a fastening section formed of the same resin material as the resin fiber, formed integrally with the resin part main body, wherein the fastening section comprises an outer cutout section and an inner cutout section formed within an annular range that surrounds a fastening member insertion hole, wherein the outer cutout section and the inner cutout section avoid each other and are disposed to be arranged alternatively in a circumferential direction of the annular range when seen in a thickness direction of the resin part main body.

12. The resin part for a vehicle according to claim 11 ,
wherein the resin part main body is formed of the fiber-reinforced resin having a matrix resin that has a melting point lower than that of the resin fiber.

13. The resin part for a vehicle according to claim 11 ,
wherein the fastening section is provided at least on the resin part main body at an outer side in the vehicle.

14. The resin part for a vehicle according to claim 11 ,
wherein the fastening section comprises an outer fastening section provided on the resin part main body at an outer side in the vehicle and an inner fastening section provided on the resin part main body at an inner side in the vehicle, and
the outer fastening section and inner fastening section face each other with the resin part main body being interposed therebetween in the thickness direction of the resin part main body.

15. The resin part for a vehicle according to claim 14 ,
wherein the fastening section comprises a hole inner circumference forming section formed along an inner circumferential edge portion of the fastening member insertion hole formed in the resin part main body, and
the outer fastening section and the inner fastening section are continuous integrally with each other via the hole inner circumference forming section and cover the inner circumferential edge portion of the fastening member insertion hole.

16. The resin part for a vehicle according to claim 11 , further comprising an outer fastening support section provided around the fastening section in the resin part main body at an outer side in the vehicle, formed of the same resin material as the resin fiber and formed integrally with the resin part mai
