PROBLEM TO BE SOLVED: To provide an electrothermal heating device that can reliably prevent, through a simple configuration, accidental contact by a user's hand with a socket-side electroconductive part disposed within a plug socket, or the adherence of dirt or the like thereupon, while an power source plug can be reliably plugged into the plug socket.SOLUTION: An electric heating device includes a box-shaped plug socket 30 provided with a socket-side electroconductive part 31 electrically connected to an electric heater 5; a power source plug 50 provided with a plug-side electroconductive part 51 electrically connectable to the socket-side electroconductive part 31 and attachable to and detachable from the plug socket 30; wherein the device includes: a protective member 35 for closing the opening 32 of the plug socket 30 and positioning the socket-side electroconductive part 31 within an interior space S; a movement-restricting mechanism R for restricting the movement of the protective member 35 both towards and away from the socket-side electroconductive part 31 in a protected state in which the socket-side electroconductive part 31 is positioned within the interior space S; and a switching mechanism Q for switching the protective member 35 from a restricted movement state into a restriction released state, in which the restriction of movement by the movement restriction mechanism R is released, as the power source plug 50 is inserted into the plug socket 30. |
