IN A STRUCTURE IN WHICH A MIDDLE PORTION OF A WIPER BLADE IS PIVOTED TO A LEADING END PORTION OF A WIPER ARM VIA A PIVOT SUBSTANTIALLY ORTHOGONAL TO AN ARM LENGTH DIRECTION SO AS TO FREELY OSCILLATE, AND A SUPPORTING MEMBER SUPPORTING A PORTION CLOSER TO A WIPER SHAFT THAN THE MIDDLE PORTION OF THE WIPER BLADE IS PROVIDED IN THE WIPER ARM, THE STRUCTURE IS MADE SUCH AS TO REDUCE A SLIDING RESISTANCE WHICH OCCURS DUE TO A MOVEMENT OF THE WIPER BLADE IN A WINDOW SURFACE DIRECTION AGAINST THE SUPPORTING MEMBER. A STABILIZER (SUPPORTING MEMBER) (13) IS CONSTITUTED BY AN UPPER PIECE PORTION (13A) AND A PAIR OF SIDE PIECE PORTIONS (13B), A SUPPORTING CONCAVE PORTION SUPPORTING A WIPER BLADE (3) IN AN OUTWARD FITTING MANNER IS FORMED, AND A PLURALITY OF RIBS (13H) WHICH ARE LONG IN THE WINDOW SURFACE DIRECTION ARE FORMED ON INNER SURFACES OF THE SIDE PIECE PORTIONS (13B), THEREBY BEING IN LINEAR CONTACT WITH OUTER SURFACES OF BOTH SIDE PIECE PORTIONS (15B) OF A SUPPORT RECEIVING BODY (15) WHICH IS OUTWARD FITTED TO A FIRST LEVER TERMINAL END PORTION (10D) OF THE WIPER BLADE (3).(FIG 4(A),4 (B),4 (C))
