<p>PROBLEM TO BE SOLVED: To provide a fuel tank capable of attaching a built-in component to a prescribed position in the fuel tank such that the built-in component is not deviated with respect to parison upon blow molding.SOLUTION: A fuel tank 1 for automobile is formed according to blow molding, allows a built-in component 20 to be attached to an internal part and has an external wall 10 formed with synthetic resin. Therein, a plurality of attachment members 30 for attaching the built-in component 20 are provided so as to be fused on an inner surface of the external wall 10 of the fuel tank 1 on the built-in component 10. Each of the attachment members 30 is provided with a contact part 32 which comes into contact with the inner surface of the external wall 10 of the fuel tank 1 and the contact part 32 has a contact surface 33 opposite to the inner surface of the external wall 10 of the fuel tank 1. The inner surface of the external wall 10 of the fuel tank 1 to which the contact surface 33 is fused forms an external wall inner surface protrusion part 18 which is extended in the inner part direction of the fuel tank 1 so as to surround the circumference of the contact surface 33.</p> |
