Abstract

A component joining structure having: a first component provided with a joint portion for joining components together; a second component formed from a resin material in which fibers are oriented in multiple directions; and a joined portion that is integrally formed to the second component using a resin material, that is in close contact with the joint portion and is joined to the joint portion, and in which the fibers are oriented in multiple directions.

First claim

What is claimed is:

1. A component joining structure comprising:
a first component comprising a main body and a joint portion, wherein the joint portion has a protruding shape, and the first component is configured such that a recess is formed between a leading end of the joint portion and the main body the first component;
a second component formed from a resin material, the resin material being formed from a plurality of sheet-shaped resin materials, fibers in each of the plurality of sheet-shaped resin materials being oriented in a single direction, and the plurality of sheet-shaped resin materials being superimposed on each other such that the fibers are oriented in multiple directions in three dimensions; and
a joined portion that is integrally formed to the second component using the resin material, and that is in close contact with the joint portion and is joined to the joint portion; wherein
the resin material and the fibers oriented in multiple directions are provided at locations of the joined portion which face the leading end of the joint portion, and at locations of the joined portion which face lateral sides of the joint portion such that the resin material and the fibers are present in the recess that is formed between the main body of the first component and the leading end of the joint portion thereof.

2. The component joining structure of claim 1 , wherein
the joint portion is configured as a protrusion leading end portion that juts out in a direction toward the periphery of the joint portion, and
the joined portion is a recessed shape on part of the second component, capable of housing the joint portion and configured with a recess bottom portion that juts out further in a direction toward the periphery of the joined portion than a recess opening portion.

3. The component joining structure of claim 1 , wherein a density of the fibers is uniform in the joined portion.
