<p>PROBLEM TO BE SOLVED: To provide an electric razor which allows an unshaved part to be reduced.SOLUTION: Negative pressure is imparted to an outer blade of an electric razor by a separate suction device 7. An outer wall is not provided on an outer periphery of the outer blade so as to keep a constant suction power without fixing the outer blade to the skin, and a position of an outer blade surface is heightened by about 0.5 millimeter more than a body of the electric razor. A pressure regulating valve is provided in a negative pressure transmission passage for operating only when the negative pressure heightens too much when the skin completely covers the whole outer blade yet. For transmitting the negative pressure to the outer blade inside from the separate suction device, weight saving is executed in a range except for a required part as a function in a conventional component of the electric razor. As a newly adding element, an inside transmission pipe is only provided for passing a residue of shaven body hair to the body case outside of the electric razor from the outer blade side of a motor holder while securing the negative pressure.</p> |
