Abstract

The present invention aims to cool high tension electrical equipment efficiently with a small, lightweight device. The high tension electrical equipment cooling structure is provided for cooling batteries which supply electricity to the operating motor via an inverter, and the inverter using cooling air, and comprises an equipment box for guiding cooling air introduced from a cooling air inlet port into a cooling air outlet port, and a fan for introducing cooling air from the cooling air inlet port. A shutter that consists of an elastic material is disposed inside the intake duct. The shutter closes off the cooling air flow path, and when negative pressure is generated downstream of the shutter due to the operation of the fan, the shutter undergoes elastic deformation, and as a result, the cooling air flow path is opened.
