Abstract

An inbuilt component fixing structure of a resin tank includes: a fastening seat that is provided to the inbuilt component, that is formed with a through-hole configured to fasten and fix the inbuilt component to the resin tank, and that has a contact face that contacts an inner face of the resin tank; a fixing section that projects out from the inner face and pierces through the through-hole, the fastening seat being fastened and fixed by being sandwiched between a jutting-out portion formed at a portion of the fixing section that has pierced through the through-hole, the jutting-out portion jutting out to a peripheral portion of the through-hole; and a weak portion that is formed at the fastening seat, that is thinner than a general portion of the fastening seat, and that has a lower rigidity in a removal direction of the fastening seat than the fixing section.

First claim

What is claimed is:

1. An inbuilt component fixing structure of a resin tank, the inbuilt component fixing structure comprising:
a plate shaped fastening seat that is provided to an inbuilt component disposed inside a resin tank, that is formed with a through-hole configured to fasten and fix the inbuilt component to the resin tank, and that has a contact face that contacts an inner face of the resin tank that is flat in shape;
a fixing section that projects out from the inner face of the resin tank and pierces through the through-hole of the fastening seat, the fastening seat being fastened and fixed by being sandwiched between the inner face of the resin tank and a jutting-out portion formed at a portion of the fixing section that has pierced through the through-hole, the jutting-out portion jutting out to a peripheral portion of the through-hole; and
a weak portion that is formed at a location of the fastening seat corresponding to a periphery of the jutting-out portion, that is thinner than a general portion of the fastening seat, and that has a lower rigidity in a removal direction of the fastening seat than the fixing section.

2. The inbuilt component fixing structure of a resin tank of claim 1 , wherein:
a circular ring-shaped groove portion is formed at a face of the fastening seat at an opposite side in a plate thickness direction to the contact face, so as to surround the jutting-out portion; and
the weak portion is a thin portion formed between the groove portion and the contact face.

3. The inbuilt component fixing structure of a resin tank of claim 2 , wherein a coupling portion, that extends from one groove wall to another groove wall and couples both the groove walls together, is provided to the groove portion.

4. The inbuilt component fixing structure of a resin tank of claim 3 , wherein a cutout, that extends along a direction intersecting an extension direction of the coupling portion, is formed at a surface of the coupling portion.
