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.

Abstract: A grass mower includes: a main body; a working unit driving motor (drive source) mounted on the main body; an output shaft that projects downward from the working unit driving motor and is rotated by the working unit driving motor; a mowing blade disk mounted to the output shaft; and an upper guard provided to cover the output shaft, the output shaft being between the mowing blade disk and the main body, wherein the upper guard includes a cutout portion for exposing the mowing blade disk at a rear end in the traveling direction of the main body.

Abstract: A pressure valve to be arranged in a seal member sealing a casing in which a capacitor element is housed, the pressure valve having a base end positioned within the case and a tip positioned outside the case. The pressure valve includes a tapered portion having a tapered shape. At the top portion of the tapered portion, there is formed a slit able to undergo a state change between a close-state and an open-state by elastic deformation. When the casing internal pressure is less than a certain value, the slit maintains the close-state. When the casing internal pressure has reached the certain value, the slit undergoes a state change to the open-state, whereby the inside and outside of the case communicate with each other and the internal pressure is released from within the case.
