To provide a reservoir tank of which assemblability can be improved.SOLUTION: In a reservoir tank, an air flow passage 40 for maintaining a pressure in a hollow part 21 at atmospheric pressure is formed in a lid member 3 and a seal member 4. The seal member 4 comprises: a first coating part 41 which has a first air hole 40a which forms a part of the air flow passage 40, a cylindrical part 411 which is located along an inner peripheral surface of an opening 22, and a cylindrical seal portion 412 which contacts the inner peripheral surface of the opening 22 over the whole circumference, and which is so located inside the opening 22 as to cover the opening 22; a second coating part 42 which has a second air hole 40b which forms a part of the air flow passage 40, and which is so located on the lid member 3 side of the first coating part 41 as to cover an opening of the cylindrical part 411; and a bendable connection part 43 which connects the first coating part 41 and the second coating part 42 to each other.SELECTED DRAWING: Figure 2
