Abstract: An electrical apparatus may be provided with: a housing; a first electrical apparatus-side terminal; a first terminal cover configured to move between a covering position and an exposing position; and a first locking member configured to engage with the first terminal cover positioned at the covering position, and configured to move between a lock position at which the first locking member restricts movement of the first terminal cover from the covering position to the exposing position and an unlock position. The first locking member may be configured to move from the lock position to the unlock position while a first target apparatus is slid in the sliding direction to be attached to the housing. When the first locking member is positioned at the lock position, a user may be unable to directly shift the first locking member from the lock position to the unlock position.

Abstract: An engine includes: a piston; a carburetor having a diaphragm fuel pump, the diaphragm fuel pump including a pump chamber configured to suck and discharge fuel and a diaphragm chamber to which a pressure to drive the pump chamber is applied; and a communicating passage configured to connect between the diaphragm chamber and a negative pressure part in which a negative pressure is created due to movement of the piston. A flowback prevention part is formed in the communicating passage to allow fluid to move only in on direction from the diaphragm chamber to the negative pressure part.
