Forward position of the side rear and strut housing 14 of the fan 13, i.e., the channel middle position of hot air H from the fan 13, that is out of the discharged hot air H by a fan 13
And is bent to the side against the front of the engine 12
At a position in the middle of the flow path, and is arranged obliquely in the front-rear direction.

Next, the battery heat-insulating cover 1 according to the embodiment of the present invention will be described with reference to FIG. That is, the battery heat-insulating cover 1 is formed by integral molding of a synthetic resin. The battery heat-insulating cover 1 is slightly larger than the outer shape of the battery B so as to cover all the side surfaces and the upper surface of the battery B. A housing portion 2 is formed, and a terminal hole 4 for projecting the terminal 3 of the battery B to the surface of the battery heat insulating cover 1 is formed on the upper surface portion (see FIG. 3). A bulging portion 6 having a wind guiding portion 5 extending rearward of the vehicle is formed on a side surface portion of the battery heat shielding cover 1 at a position facing the flow path of the hot air H. In the bulging portion 6, a space is formed between the air guiding portion 5 and the housing portion 2, and a heat insulating layer 7 is formed by an air layer in the space. In addition, the said wind guide part 5 is a figure.
