Abstract

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.
