<P>PROBLEM TO BE SOLVED: To prevent dust and water from entering a battery case arranged outside a cabin, and to hardly transmit noise and vibration of a cooling fan to the cabin. <P>SOLUTION: An intake duct 48 for sucking cooling air into a battery case 24 and an exhaust duct 49 for exhausting the cooling air from inside the battery case 24 are arranged between the battery case 24 and a cabin 25, so the battery case 24 is interposed between a road surface and the intake duct 48 and exhaust dust 49 to make it hard for dust and water scattered from the road surface and wheels to enter from the intake duct 48 and exhaust duct 49. Further, an exhaust passage 57 of the exhaust duct 49 is arranged between a cooling fan 47 and the cabin 25, so the noise generated by the cooling fan 47 is cut off by the exhaust passage 57 and hardly transmitted to the cabin 25, and water entering from the cooling fan 47 at a stop is further effectively prevented from entering the battery case 24 in such a case since the exhaust passage 57 is positioned above the cooling fan 47. <P>COPYRIGHT: (C)2013,JPO&INPIT |
