摘要

A pipe connecting structure a pipe-type modular wiper apparatus including: a bracket (3) to which a wiper motor (2) is fastened; and a bracket (5) to which a wiper shaft (4) is fastened and which is, via a pipe member (6), integrally connected to the bracket (3) to which a wiper motor is fastened. The pipe member (6) is integrally fastened to the brackets (3, 5) by integrally inserting a pipe nut (15) into an insertion hole (6a) formed at a position at which the pipe member is connected to the bracket in such a manner that a bolt (13) is, in a thread manner, inserted from the bracket side in a state where the bracket is brought into contact with a head portion of the pipe nut (15) projecting over the pipe member in such a manner that a recess-groove shape fastening groove portion (3c) is formed in a portion of the bracket to which the pipe member is fastened, the pipe member is fitted to the fastening groove portion so as to be tightened by the bolt (13), the fastening groove portion has a depth with which the pipe member can be fitted by a degree larger than the half of the pipe member and two introduction surfaces (3b) of the fastening groove portion through which the pipe member is introduced are made to be parallel surfaces facing a direction of a tangent of the outer circumference of the pipe member.
