PROBLEM TO BE SOLVED: To shorten an air introducing passage for introducing air for cooling a battery cell to reduce flow resistance in air flow. SOLUTION: A battery pack 10 is installed in a position neighboring to a cabin with a cover panel 16 under a seat therebetween, and the air for cooling the battery pack 10 is introduced from a slit 96 provided in the cover panel. The air introducing passage (the slit 96, a suction chamber 92, an opening 94, an air introducing duct 34, and a gas flowing-in chamber 32) is shortened by this manner to reduce the air-flowing resistance for the air for the cooling. Cooling effect for the battery pack 10 gets sufficient thereby. Since a length of a component for constituting the air introducing passage, for example the air introducing duct 34, is shortened also, a component cost of the duct 34 is reduced to provide an advantage that the battery pack 10 gets inexpensive.
