ABSTRACT OF THE DISCLOSURE There is disclosed a windshield wiper device for wiping the window glass of an automotive vehicle. The windshield wiper includes: an arm head, a retainer, an arm spring, and a wiper blade. The arm head is adapted to be fixed to the wiper shaft of the vehicle so as to oscillate about an axis of oscillation. The retainer is pivotally connected to the arm head for movement about a pivot axis extending perpendicularly to the axis of oscillation. The arm spring is interposed between the arm head and the retainer member to urge the retainer member toward the window glass upon the fixation of the arm head to the wiper shaft. The arm piece is disposed perpendicularly to the pivot axis and is rotatably connected to the retainer member for movement about the longitudinal axis of the arm piece. The wiper blade is connected to the arm piece so as to be pressed against the window glass by the arm spring upon the fixation of the arm head to the wiper shaft. The wiper blade squeegees the window glass when the arm head is oscillated. The wiper device further includes a mechanism for converting the pivotal movement of the retainer into the rotational movement of the arm piece so that, when the retainer is pivoted about the pivot axis, the wiper blade is turned about the longitudinal axis of the arm piece.
