ABSTRACT:
A squeegee for use in a windshield wiper apparatus includes a wiping portion which has a smoothly tapered shank, tapering from a first thickness to a reduced second thickness, the quotient defined by the difference of the first thickness minus the second thickness divided by the first thickness being approximately 0.6 whereby the shank simulates a constant stress beam to preclude stress concentration areas in the squeegee.
