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;
- an arm piece mounted at one end portion thereof to a distal end portion of said arm shank and having the wiper blade attached to another end portion thereof remote from the distal end portion of said arm shank;
- and
- an arm piece cover covering said arm piece and having an outer peripheral surface generally flush with an outer peripheral surface of the distal end portion of said arm shank, the arm piece cover comprising a cover body that covers a surface of the arm piece opposite from the window glass, a side wall that extends from one of opposite side edges of the cover body to cover a side surface of the arm piece, and a projecting wall section that projects from the side wall of the arm piece cover and covers a surface of the arm piece facing the window glass,
- wherein the projecting wall section has a positioning hole and the arm piece has a locking pin at a surface of the arm piece facing the window glass, the locking pin engaging the positioning hole.
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;
- an arm piece mounted at one end portion thereof to a distal end portion of said arm shank and having the wiper blade attached to another end portion thereof remote from the distal end portion of said arm shank;
- and
- an arm piece cover covering said arm piece and having an outer peripheral surface generally flush with an outer peripheral surface of the distal end portion of said arm shank,
- wherein said arm piece cover has a cover body that covers a surface of said arm piece opposite from the window glass, and a side wall that extends from one of opposite side edges of the cover body to cover a side surface of said arm piece,
- wherein said arm piece cover has a projecting wall section that projects from the side wall of said arm piece cover along a surface of said arm piece facing the window glass,
- wherein one end portion of said arm piece cover is held in end-to-end abutment against the distal end portion of the arm shank in an abutment region between said arm piece cover and said arm shank,
- wherein the projecting wall section of said arm piece cover has, in a portion thereof adjacent to the distal end portion of said arm shank, positioning means and expansion/contraction permitting means located remoter than the positioning means from the abutment region, and
- wherein said expansion/contraction permitting means has an expansion/contraction margin for permitting thermal expansion/contraction of said arm piece cover in a longitudinal direction of said arm piece cover.
