Abstract
A sealing construction is disclosed herein for a casing preferably for an electric shaver which is formed by first and second casing members which are to be pressed together through an annular sealing element to provide a seal between the sealing surfaces of the first and second casing members. The first casing member is formed in its sealing surface with an annular groove for retaining the annular sealing element in position, such sealing element being made of elastic material and having an axially projecting and rounded top portion above the sealing surface of the first casing member. Also projected on the second casing member is an annular plug of convex-shaped in cross section which aligns with said annular sealing element so as to be engageable with the rounded top portion thereof. When the first and second casing members are compressed together, the rounded top portion of the sealing element is deformed by being urged by the annular plug in such a way as to wrap around the annular plug both radially inwardly and outwardly thereof, providing an effective seal between the sealing surfaces of said first and second casing members.
