  • Publication number: 20170263394
    Abstract: The present invention implements, through a simple structure, the prevention of an electric shock caused by contacting an output terminal in a conducting state. This electric shock protection structure is provided with: a protective cover (40) which changes an output terminal into a non-conducting state by pressing a power switch (51) during the transition of the output terminal from a covered state to an exposed state; and a housing cover (60) which cannot be moved when the output terminal is in the non-conducting state by having an L-shaped curved section (60A), which is positioned on a different surface from the surface on which the output terminal is disposed, does not contact a contact section (44A) of the protective cover (40) when the protective cover (40) exposes the output terminal, and contacts the contact section (44A) when the protective cover (40) covers the output terminal.
