PROBLEM TO BE SOLVED: To provide a reserve tank device for a vehicle capable of efficiently preventing leakage of cooling water.SOLUTION: A water filling pipe 7 having a communication port 10 on a lower end and a water filling port 11 on an upper end is connected to a reserve tank body 6, and an atmosphere open passage 17 for communicating an inside and an outside of the reserve tank body 6 is formed on a distal end on the water filling port 11 side of the water filling pipe 7. A connection pipe 8 is provided on the reserve tank body 6 in order to attach a hose 12 for transferring cooling water to and from a radiator 1. A groove 15 for storing the hose 12 is formed at least on one outer surface of the reserve tank body 6. The groove 15 is formed by recessing the outer surface side of the reserve tank body 6, and an inner surface side of the reserve tank body 6 is protruded between a storage possible maximum specified water level of the reserve tank body 6 and the communication port 10 of the water filling pipe 7. |
