Abstract: A work machine wherein motive power of a drive part is transmitted to an operation part through a shaft, the shaft being inserted into a cylindrical part and supported by a plurality of bearing members. In the cylindrical part, the plurality of bearing members are disposed on the node side of vibration generated in the shaft or the cylindrical part.

Abstract: 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.

Abstract: The lawn mower has at least a first structure in which a pair of power receiving terminals are separately disposed in the vehicle body cover and the vehicle body that are different parts from among a plurality of parts constituting the lawn mower, or a second structure in which the power receiving terminal, which is one of the pair of power receiving terminals, has a downward-facing contact surface that comes into contact with the charging station.
