摘要： In a lawn mower, one power receiving terminal is provided on a surface of the lawn mower, and the other power receiving terminal is disposed in a position where it sandwiches at least a part, such as the upper front portion, of a vehicle body with the one power receiving terminal. This configuration serves to suppress a situation in which moisture establishes electrical continuity between the pair of power receiving terminals.
