A water and dust-proof electric shaver head support structure that provides a wide range of movement to the floating shaver head to closely follow the contours of the skin. The floating shaver head, which contains the motor and shaving blades, freely pivots in the lateral plane and telescopically floats in relation to the shaver grip. A box-like space is formed in the shaver grip below the lower surface of the shaver head, and front and rear support walls extend upward from the shaver grip to support the shaver head in the forward/rearward direction.
