<P>PROBLEM TO BE SOLVED: To prevent leakage of cooling water from a water filling port by a simple structure without increasing the number of components. <P>SOLUTION: This vehicular reserve tank 1 includes: a cubic tank body 10 for storing cooling water; a pipe-shaped water filling pipe 20 having a lower end connected at a communication port 10g of the tank body 10 and formed with a water filling port 21 at the upper end; a cap 22 detachably mounted to the water filling port 21; and an atmosphere opening communication path formed between the water filling pipe 20 and the cap 22 for making the inside of the water filling pipe 20 communicate with the outside at the atmospheric pressure; and further includes a pair of projecting parts 12, 13 located at an upper part relative to the highest level of the cooling water in a pair of sidewalls 10a, 10b extending in the vertical direction of the tank body 10 and facing each other, and on the lower side of the communication port 10g, and facing each other by projecting to the inside of the tank body 10. In the vehicular reserve tank, space parts 15, 16 each having an area larger than the area of a space between the pair of projecting parts 12, 13 viewed from above are formed on both sides of the pair of projecting parts 12, 13 in the tank body 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
