A wiper apparatus that decreases the number of tightening means and can efficiently carry out connecting and fixing work with respect to integration of a wiper motor and pivot axes with a pipe member. A linkage piece at the second pivot axis side is arcuately formed so as to match half the outer circumference of a linkage pipe member, a linkage piece at the wiper motor side is formed so as to be arcuate, on the inner circumferential surface of which, an external fitting portion of a pipe member along the outer circumference of the linkage pipe member and an external fitting portion of the linkage piece along the outer circumference of the linkage piece are formed. The respective linkage pieces, that are disposed on the outer circumference of the linkage pipe member, are connected in a laminated manner at the position of the external fitting portion of the linkage pieces.
A unit wiper apparatus having a wiper motor and a pivot axis incorporated in a pipe member via respective attaching portions, wherein linkage pieces are formed on the respective attaching portions along the outer circumference of the pipe member, at least parts of the respective linkage pieces are laminated on an outer circumference of the pipe member when connecting the linkage pieces to the pipe member and fixing the same thereat, and the connection and fixation on the laminated portion is made by at least one connecting means.
A linkage system, comprising:
A method of attaching a wiper motor and a pivot shaft sleeve to a linkage pipe member, comprising:
