Abstract
A fuel tank structure includes: a fuel tank that is installed in an automobile and that accommodates fuel; a bag-shaped member that is fixed to a ceiling portion of an interior of the fuel tank, and whose state of contact with a liquid surface of fuel accommodated in the fuel tank is maintained due to the bag-shaped member inflating or deflating in accordance with a height of the liquid surface; a temperature sensor that senses a temperature of the fuel or evaporated fuel that is within the fuel tank; and a cooling wind introducing section that introduces cooling wind into an interior of the bag-shaped member in a case in which the temperature of the fuel or the evaporated fuel detected by the temperature sensor becomes higher than a predetermined temperature.

A fuel tank structure comprising:
- a fuel tank that is installed in an automobile and that accommodates fuel;
- a bag-shaped member that is fixed to a ceiling portion of an interior of the fuel tank, a state of contact of the bag-shaped member with a liquid surface of fuel accommodated in the fuel tank being maintained due to the bag-shaped member inflating or deflating in accordance with a height of the liquid surface;
- a temperature sensor that detects a temperature of the fuel or evaporated fuel that is within the fuel tank;
- and
- a cooling wind introducing section that introduces cooled air into an interior of the bag-shaped member in a case in which the temperature of the fuel or the evaporated fuel detected by the temperature sensor is higher than a predetermined temperature, wherein
- the cooling wind introducing section includes an introducing pipe that introduces the cooled air into the bag-shaped member, and a cooling device that cools the cooled air that flows through the introducing pipe.

- and
- a cooling wind introducing section that introduces cooling air into an interior of the bag-shaped member in a case in which the temperature of the fuel or the evaporated fuel detected by the temperature sensor is higher than a predetermined temperature, wherein
- the cooling wind introducing section does not introduce the cooling air into the interior of the bag-shaped member in a case in which the temperature of the fuel or the evaporated fuel detected by the temperature sensor is not higher than the predetermined temperature.
