2. Description of the Related Art In a vehicle wiper for wiping a windshield glass of an automobile, a wiper blade is rotatably held by a wiper arm. Here, generally, a wiper blade is known as a so-called tournament type in which a plurality of holding levers are connected to follow a windshield glass curved surface, but unlike this, the backing itself is curved into a predetermined shape. There is a wiper blade (curved so as to follow the curvature of the windshield glass surface) and a plurality of holding levers are abolished (for example, Japanese Patent Publication No. 2001-500091).

This type of wiper blade has a plurality of holding levers, so that the height of the blade can be reduced, and the wiper blade is excellent in performance at high speed running (prevention of wind noise and rising). .

By the way, in the wiper blade disclosed in the above publication, grooves are provided on both side surfaces of the blade rubber in the longitudinal direction, and a supporting member having a spring rail is arranged in each groove. Is held by the connecting device. This connecting device has a structure in which it is divided along the transverse direction of the blade rubber, and has a structure in which a supporting member is sandwiched from both sides and the divided two device parts are joined by welding or adhesion. In addition, as another example, a configuration is also disclosed in which the base portions of the divided connection devices are fastened with screws and coupled.

As described above, in the conventional wiper blade having a structure in which a plurality of holding levers are omitted, a connecting device for holding the blade rubber together with the backing (supporting member) and rotatably connecting the blade rubber to the tip end portion of the wiper arm is not provided. Since it has a structure divided in the blade transverse direction, when connecting and connecting them, while holding the backing fitted in the blade rubber groove so as not to fall out of this groove,
Furthermore, while maintaining the state in which the backing is sandwiched from both sides, the connecting devices of the divided structure must be welded, glued, or screwed together (in other words, multiple parts are not yet completely fixed and unstable. In this state, the work of connecting the respective parts must be performed), which is a poor workability.

Further, it is difficult to disassemble the parts again after the two device parts of the connecting device having the structure divided along the transverse direction of the blade rubber as described above are once joined by welding or adhesion. Therefore, even if the blade rubber wears, it is not possible to replace only this blade rubber, not only maintenance becomes expensive, but also the wiper blade to be discarded is a combination of a metal material and a rubber material, It was supposed to prevent the reuse of the waste wiper blade.
