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.

Il s'agit d'une structure conçue pour relier des tubes d'un appareil d'essuyage modulaire de forme tubulaire. La structure comprend un premier support auquel un moteur d'essuyage est fixé, et un deuxième support auquel est fixé une tige d'essuyage et qui est, par le biais d'un montant en forme tubulaire, intégralement relié au premier support. Le membre tubulaire est intégralement fixé aux supports en insérant un écrou tubulaire dans un trou d'insertion pratiqué dans le montant tubulaire de façon à relier le montant au support; un verrou est inséré, à travers le support, dans la tête du tube, et vient se projeter par dessus le montant tubulaire contenu dans une portion de fixation à rainure en retrait pratiquée dans la partie du support à laquelle le montant tubulaire est fixé. Le montant tubulaire s'insère dans la portion de fixation à rainure de façon à être serré par le verrou. La portion contenant la rainure de fixation est deux fois plus profonde que l'autre moitié du montant tubulaire. Deux surfaces d'introduction de la portion de fixation à rainure à travers laquelle le montant tubulaire est inséré sont parallèles et tangentes à la circonférence extérieure du montant tubulaire.
