PURPOSE:To prevent fuel from overflowing out of a tank without decreasing the tank capacity by configurating a device in such a way that a separator chamber is provided at a corner section of a tank main body, and each of three vapor pipes is communicated as specified. CONSTITUTION:A vapor exhausting device 6A is provided in an upper space S of a tank main body 1, and the device 6A is composed of a separator chamber 12, and three vapor pipes 13 through 15 which are communicated with the separator chamber 12. And NO.1 vapor pipe 13 is communicated with the lower portion of the inner wall of the chamber 12, and its one end 13a if opened to the upper portion along the side wall of an another projected section 3B of the tank main body 1 where the pipe is bent up. NO.2 vapor pipe 14 is connected with the chamber 12 passing through its side wall, and its one end 14a is opened to a place where it is projected out of the tank main body 1 while the other end 14b is opened to an upper space of the chamber 12 where it is bent up. And furthermore, NO.3 vapor pipe 15 is communicated with the bottom of the chamber 12, and its one end 15a is opened to a corner section of the tank main body 1. |
