Abstract
An electric shaver comprises an inner case which retains an electronic part board and an outer casing which retains a plug pin board which secures a plurality of plug pins. The inner case is fabricated of a plastic integral with a bottom wall. The electronic part board is disposed above the lower separating wall while the plug pin board is disposed under the lower separating wall. Metal pins penetrating the lower separating wall connects the electronic part board and the plug pin board. The bottom opening of the outer casing is closed with a bottom cover. The bottom cover has a pair of through holes through which extend outwardly a pair of plug pins.

wherein the inner case is fixed to the electronic parts board on one side thereof so that at least one heat-generating part, which is mounted on the electronic parts board, is received in the space between the electric motor and the battery. -
11. An electric shaver as claimed in claim 10, wherein the inner case includes an integrally formed plastic tubular case for retaining the battery, and the upper end of the tubular case is closed.
-
12. An electric shaver as claimed in claim 10, wherein the heat-generating part protrudes from the electronic parts board.
-
13. An electric shaver as claimed in claim 10, wherein the heat-generating part is a charging resistor connected in series with the battery, a semiconductor switching element for controlling charging and discharging operations, or a power source transformer for charging the battery.
-
14. An electric shaver as claimed in claim 1, wherein the bottom cover includes a chamber and a separation wall disposed in the chamber between the plug pins.
-
15. An electric shaver as claimed in claim 14, further comprising a power source plug, which is to be inserted into the chamber of the bottom cover, wherein the power source plug has a recess for receiving the separation wall when the power source plug is inserted into the chamber.
-
16. An electric shaver recited in claim 14, wherein one end of the separation wall joins an internal wall of the chamber, and the other end of the separation wall is separated from the internal wall of the chamber by a gap which communicates with a valve hole of a safety valve provided at a bottom of the chamber.
