A pipe connecting structure for a pipe-type modular wiper apparatus includes a first bracket to which a wiper motor is fastened, and a second bracket to which a wiper shaft is rotatably fastened and which is, via a pipe member, integrally connected to the first bracket. The pipe member is integrally fastened to the brackets by inserting a pipe nut into an insertion hold formed in the pipe member at a position at which the pipe member is connected to the bracket and a bolt is inserted through the bracket into a head portion of the pipe nut projecting over the pipe member contained in a recess-groove shape fastening groove portion formed in a portion of the bracket to which the pipe member is fastened. The pipe member fits within the fastening groove portion so as to be tightened by the bolt. The fastening groove portion has a depth greater than half of the pipe member. Two introduction surfaces of the fastening groove portion through which the pipe member is introduced are parallel, tangent to the outer circumference of the pipe member. |
