PROBLEM TO BE SOLVED: To solve the problem that when a cap is formed using a resin material having a coefficient of thermal expansion larger than that of a resin material forming a tank body, sizes to expand between the outside of an opening of the tank body and the cap are different from each other when an outdoor temperature is high, and a gap results in being formed between outside of the opening of the tank body and the cap, and accordingly the cap may come off during traveling after the tank body has been mounted.SOLUTION: A reserve tank includes a tank body storing a liquid, and a tube injecting a liquid to the tank body. A swelling part penetrating the tube therethrough is provided on a part of the tank body. The tube is formed integrally with the tank body and the swelling part by blow molding.SELECTED DRAWING: Figure 3 |
