Abstract

To provide a component mounting structure for a fuel tank capable of suppressing an increase in the weight of the tank body and reducing the weight and thickness of the fuel tank component, the component mounting structure includes: a tank body (2) provided with an oblong opening (2a); a pump module (3) serving as a tank component mounted to the tank body (2); a flange (5) that is provided to the pump module (3) so as to project out from an outer surface of the pump module (3), has an oblong contour larger than the opening (2a) and having a minor dimension (W2) smaller than a major dimension (L1) of the opening (2a), and is placed inside the tank body (2) through the opening (2a) with an edge thereof opposing the tank body (2) over an entire circumference; a sealing member (7) placed between the tank body (2) and the flange (5); and a fastening member (8b•9, 11•12) that holds the pump module (3) to the tank body (2) while compressing the sealing member (7) via the flange (5).

Claims

1. A component mounting structure for a fuel tank, comprising:

a tank body provided with an oblong opening;

a tank component mounted to the tank body;

a flange that is provided to the tank component so as to project out from an outer surface of the tank component, has an oblong contour larger than the opening and having a minor dimension smaller than a major dimension of the opening, and is configured to be capable of being inserted in the opening, so that the flange is placed inside the tank body with an edge thereof opposing the tank body over an entire circumference;

a sealing member placed between the tank body and the flange; and

a fastening member that holds the tank component to the tank body while compressing the sealing member via the flange.

2. The component mounting structure according to claim 1, wherein the fastening member comprises:

an overhanging wall provided to the tank component to project out from the outer surface of the tank component at a position displaced from the flange in an outward direction of the tank such that the overhanging wall is placed outside the tank body when the tank component has been mounted to the tank body; and

a pair of semi-annular members press-fitted between the tank body and the overhanging wall to compress the sealing member.

3. The component mounting structure according to claim 2, wherein the semi-annular members each has protrusions or recesses engaging the tank body and the overhanging wall.

4. The component mounting structure according to claim 1, wherein the fastening member comprises:

a screw thread formed on the tank component so as to be placed at a position outside the tank body or opposing the opening when the tank component has been mounted to the tank body; and

a screw member that threadably engages the screw thread to cause a reaction force to act upon an outer surface of the tank body to compress the sealing member.

5. The component mounting structure according to claim 1, wherein the fastening member comprises:

an overhanging wall provided to the tank component to project out from the outer surface of the tank component at a position displaced from the flange in an outward direction of the tank such that the overhanging wall is placed outside the tank body when the tank component has been mounted to the tank body; and

a press-fit member press-fitted between the tank body and the overhanging wall to compress the sealing member.
