ABSTRACT:
A reserve tank includes a tank body having an opening for pouring coolant into the tank body and a cap closing the first opening. The cap includes an overflow passage for discharging overheated coolant and vapor to the exterior of the tank body. The overflow passage has a second opening which opens in a downward direction. The overflow passage is formed in a groove shape on an inner surface of the cap. Additionally, when the cap fits onto the opening, a sloped portion is provided in the tank body to face the second opening portion. As a result, overflowing heated coolant and vapor are discharged from the second opening through the overflow passage, and are smoothly discharged along the sloped portion.
