Abstract

A working machine may include a battery box and a battery detachably attached to the battery box. The battery box may include a top cover, and a battery cover having a shape that covers the battery attached to the battery box and being pivotable about a pivot axis with respect to the top cover. When the battery box is viewed in a top plan view in an open state in which the battery cover is open, the battery cover and the top cover may at least partially overlap with each other. When the battery box is viewed in the top plan view in a closed state in which the battery cover is closed, the battery cover and the top cover may at least partially overlap with each other.
