本発明は、自動車のフロントガラスワイパーを駆動する
アーム（以下、ワイパーアームという）に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an arm for driving a windshield wiper of an automobile (hereinafter referred to as a wiper arm).
従来のワイパーアームは、細長い杆体の一端に、ワイパ
ーブレードを装着するための部分を設け、かつ他端を、
Ｕ字状の断面をなす固定部材（以下、支持杆あるいは取
付杆という）に連結した構造になっている。A conventional wiper arm has a part for attaching a wiper blade to one end of an elongated rod, and a part for attaching a wiper blade to the other end.
It has a structure in which it is connected to a fixing member (hereinafter referred to as a support rod or mounting rod) having a U-shaped cross section.
この型式のワイパーアームについては、フランス特許公
開筒２，１５７，３７２Ａ号明細書に詳しく記載されて
いる。This type of wiper arm is described in detail in French Patent No. 2,157,372A.
この先行の装置では、杆体におけるワイパーブレードを
連結する側と逆側の端部近くに、円形の孔をあけである
。取付杆におけるＵ字状断面の底辺には、この孔と同寸
法で同形状の突起部を、Ｕ字溝の中に向けて突設しであ
る。In this prior device, a circular hole is drilled near the end of the rod opposite from the side where the wiper blade is connected. At the bottom of the U-shaped cross section of the mounting rod, a protrusion having the same dimensions and shape as the hole is provided to protrude into the U-shaped groove.
杆体と取付杆とを結合する際には、杆体の端部を取付杆
の中に挿入し、取付杆の突起部を杆体の孔に係合させる
。次いで、取付杆のＵ字の縁を、杆体の端部に対応する
ように折り曲げて、取付杆で杆体を包みこませ、杆体を
取付杆の中に、離脱しないように固着する。When connecting the rod and the mounting rod, the end of the rod is inserted into the mounting rod, and the protrusion of the mounting rod is engaged with the hole in the rod. Next, the U-shaped edge of the mounting rod is bent to correspond to the end of the rod, the rod is wrapped around the rod, and the rod is fixed in the mounting rod so that it will not come off.
上述のような従来のワイパーアームは、杆体に孔をあけ
、かつ取付杆に対応する突起部を形成する等の手数がか
かって、製作費が高価につく。また、杆体を取付杆に組
み付ける作業は、自動組立ラインに適合しないので、多
くの労力を必要とする。The conventional wiper arm as described above requires a lot of work such as drilling a hole in the rod and forming a protrusion corresponding to the mounting rod, resulting in high manufacturing costs. Further, the work of assembling the rod to the mounting rod requires a lot of labor because it is not compatible with an automatic assembly line.
突起部と孔とを使用するため、結合部が大きい表面積で
係合することとなり、アームの長さを、使用条件に合わ
せて調節することが困難である。Due to the use of protrusions and holes, the coupling portion engages over a large surface area, making it difficult to adjust the length of the arm to suit the conditions of use.
また、２個の部品の表面を、前処理をしておいても、杆
体を取付杆に挿入する際に、杆体の表面が、取付杆の突
起部によって傷つけられるおそれがある。Further, even if the surfaces of the two parts are pretreated, there is a risk that the surface of the rod may be damaged by the protrusion of the mounting rod when the rod is inserted into the mounting rod.
さらに、板材からなる取付杆をプレス加工して、突起部
を形成するために、フロントガラスワイパーの外観が損
なわれることになる。Furthermore, since the mounting rod made of plate material is press-worked to form the protrusion, the appearance of the windshield wiper is impaired.
本発明は、杆体を取付杆に対して、きわめて簡単で安価
な手法で、効率よく固定するとともに、アームの外観を
損なわないようにしたフロントガラスワイパーを提供す
