PROBLEM TO BE SOLVED: To solve a problem that a cap possibly detaches from a tank body during an in-vehicle running caused by a gap occurring between an outer side of opening of the tank body and the cap under a high air temperature due to their difference in degree of thermal expansion in a case that the cap is formed of a resin material with a thermal expansion coefficient larger than that of a resin material forming the tank body.SOLUTION: A reserve tank has a liquid storing tank body and a tube to pour a liquid into the tank body. The tank body has, in a section, a swelling part where the tube penetrates, and the tube is integrally formed by blow molding with the tank body and the swelling part. |
