Claim:
A wiper apparatus for wiping a window glass of a vehicle by means of a wiper blade, said wiper apparatus comprising: an arm shank pivotably supported at a proximal end portion thereof on the vehicle near the window glass, said arm shank having an opening portion opposed to the window glass and an inner space located inwardly of the opening portion; an arm piece mounted to a distal end portion of said arm shank and having the wiper blade attached thereto; and wind-noise preventing means provided between said arm piece and the proximal end portion of said arm shank and having a protrusion portion protruding through the opening portion toward the window glass so as to prevent an air flow, produced by traveling of the vehicle, from entering the inner space through the opening portion, and a proximal end portion extending from the protrusion portion through the opening portion into the inner space, wherein the proximal end portion of said wind-noise preventing means partitions off the inner space into a distal-end-side space and a proximal-end-side space, wherein said arm shank further has a connection member spaced from the proximal end portion of the arm shank, wherein said wiper apparatus further comprises a biasing member having a first end connected to the proximal end portion of the arm shank and a second end connected to the connection member, and wherein the proximal end portion of the wind-noise preventing means extends toward the distal end portion of the arm shank away from the connection member to a fixation portion which engages an upper wall of the arm shank.
