Abstract: A circuit breaker for an electric device has a pair of switching pieces, an electric circuit for supplying electric power to the device, an arrangement for opening the electric circuit, an arrangement for locking the switching pieces to normally close the electric circuit, a drive connected in parallel with the power source via a gate for releasing the locking arrangement, and a terminal piece located in the device and connected to the electric circuit by a cord. The cord picks up leakage current in the device to turn the gate on by the leakage current when the device becomes immersed in water. The turning on of the gate effects the release of the locking arrangement, so that the switching pieces open the electric circuit.

Abstract: In a clothes shaver or an electric shaver having an outer blade including mesh, inner blades which are energized to the direction of the outer blade in a state of standing by a blade force up spring, and a fan which is fit to a rotary shaft of an inner blade supporting base and is possible to rotate with the inner blade supporting base, when fixing the fan of the blade force up spring is pressed to the bottom face of the inner blade supporting base by an end face of the fan which faces to the bottom face of the inner blade supporting base to fix on the bottom face thereof in one action.

Abstract: In an inner rotary cutter for an electric shaver formed by providing a rotary disk at its circumference with a plurality of blade sections at prescribed intervals, a cup-shaped base section is provided which is formed by extending a cylinder section from a circular section in the axial direction to a prescribed length, the base section on its circumference is provided, in one body, with vertically extended sections projecting in the axial direction, each vertically extended section at its tip is provided, in one body, with a horizontally extended section projecting approximately in the radial direction, and the front edge of the horizontally extended section in the direction of rotation is formed into a blade. A ceramic blade may be glued on the end face of the horizontally extended section.
