Abstract

A vehicle-use resin module including a strength member made of synthetic resin and including a mounting hole, and an attachment member attached to the mounting hole and configured to be subjected to an external force. The attachment member includes an outer fitting having a tubular part arranged in the mounting hole in an inserted state. The outer fitting includes an outer circumferential projection projecting to a radially outer side of the tubular part. The strength member is an insertion-molded component having a structure in which the outer circumferential projection of the outer fitting is embedded so as to be inserted inside a circumferential wall of the mounting hole. A surface of the tubular part of the outer fitting and a surface of the outer circumferential projection are each directly fixed to the strength member with an adhesive.

First claim

What is claimed is:

1. A vehicle-use resin module comprising:
a strength member made of synthetic resin and including a mounting hole; and
an attachment member attached to the mounting hole and configured to be subjected to an external force, the attachment member including an outer fitting having a tubular part arranged in the mounting hole in an inserted state, the outer fitting including an outer circumferential projection projecting to a radially outer side of the tubular part, wherein
the strength member comprises an insertion-molded component having a structure in which the outer circumferential projection of the outer fitting is embedded inside a circumferential wall of the mounting hole such that the outer circumferential projection is inserted inside the circumferential wall, and
a surface of the tubular part of the outer fitting and a surface of the outer circumferential projection are each directly fixed to the strength member with an adhesive.

2. The vehicle-use resin module according to claim 1 , wherein a reinforcer made of metal is fixed to the strength member, and the outer circumferential projection of the outer fitting is overlapped with the reinforcer in a center axis direction of the mounting hole.

3. The vehicle-use resin module according to claim 2 , wherein the reinforcer integrally includes a circumferential-wall reinforcer positioned in the circumferential wall of the mounting hole and a plate-shaped reinforcer extending from the circumferential wall of the mounting hole to the radially outer side.

4. The vehicle-use resin module according to claim 2 , wherein the reinforcer is spaced apart from an inner circumferential surface of the mounting hole to the radially outer side, and an axis-perpendicular intermediate resin layer comprising the synthetic resin that constitutes the strength member is interposed between the reinforcer and the tubular part of the outer fitting.

5. The vehicle-use resin module according to claim 2 , wherein the reinforcer is exposed on an inner circumferential surface of the mounting hole, and the reinforcer and the tubular part of the outer fitting are in contact with each other.

6. The vehicle-use resin module according to claim 2 , wherein the reinforcer and the outer circumferential projection are spaced apart from each other in the center axis direction of the mounting hole, and an axial intermediate resin layer comprising the synthetic resin that constitutes the strength member is interposed between the reinforcer and the outer circumferential projection.

7. The vehicle-use resin module according to claim 2 , wherein at least one of the outer circumferential projection of the outer fitting and the reinforcer is provided continuously about an entire circumference of the mounting hole in a circumferential direction.

8. A method of manufacturing a vehicle-use resin module comprising a strength member made of synthetic resin and including a mounting hole, and an attachment member attached to the mounting hole and configured to be subjected to an external force, the method comprising:
adopting an outer fitting in the attachment member, the outer fitting including a tubular part configured to be arranged in the mounting hole in an inserted state and an outer circumferential projection projecting to a radially outer side of the tubular part;
inserting the outer fitting into a forming cavity of a mold of the strength member; and
performing insert molding by filling the forming cavity with resin material with an adhesive attached to the tubular part and the outer circumferential projection of the outer fitting such that, at the same time of molding of the strength member, the tubular part of the outer fitting is adhered to the mounting hole of the strength member while the outer circumferential projection of the outer fitting is embedded and adhered inside a circumferential wall of the mounting hole such that the outer circumferential projection is inserted inside the circumferential wall.

9. The method of manufacturing a vehicle-use resin module according to claim 8 , wherein a reinforcer configured to be embedded inside the strength member is set within the forming cavity of the strength member together with the outer fitting with an adhesive attached to an outer circumferential surface of the reinforcer such that the reinforcer is adhered to the strength member at the same time of molding of the strength member.

10. The vehicle-use resin module according to claim 1 , wherein the attachment member further includes an inner fitting inserted into the outer fitting, and a rubber elastic body disposed radially between the outer fitting and the inner fitting, the rubber elastic body being bonded by vulcanization to an inner circumferential surface of the outer fitting and an outer circumferential surface of the inner fitting.

11. The method of manufacturing a vehicle-use resin module according to claim 8 , wherein the attachment member further includes an inner fitting inserted into the outer fitting, and a rubber elastic body disposed radially between the outer fitting and the inner fitting, the rubber elastic body being bonded by vulcanization to an inner circumferential surface of the outer fitting and an outer circumferential surface of the inner fitting.
