ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of Invention
The invention relates to a mounting structure of a vehicle wiper (windshield wiper) apparatus for mounting to motor vehicles, such as cars, buses and trucks.
2. Description of Related Art
Among vehicle wiper apparatus there is the modular type in which right and left hand pivot shafts to which right and left hand wiper arms are fitted and a wiper motor serving as a power source for placing these wiper arms into an oscillating or swinging motion are integrally built in a modular type holder member. In such a modular type wiper apparatus, the mounting or connection to a vehicle body is accomplished at three sections: right and left hand pivot holder sections and a motor holder section, as disclosed in JP-Y2-7-51953. Although the positions of the mountings of the right and left hand pivot holder sections to the vehicle body are provided at outer edge positions of a window or windshield (for example, at the driver side position), the mountings for the right and left hand pivot holder sections are outside the pivot shafts in the right and left directions to prevent interference with a link connecting the pivot shafts.
In recent years, to enlarge the vehicle interior space and improve the passenger's comfort, the windshield is laid out forwardly in an offset way in the vehicle, thereby resulting in less space for mounting a wiper apparatus. Additionally, the mounting positions of the modular type wiper apparatus to the vehicle body are set so as not to interfere with the link, as mentioned above. While the mounting of the wiper apparatus to the vehicle body requires mounting seats on the vehicle body side, difficulty is experienced in laying out the positions of the mountings within a limited mounting space of the vehicle body. Additionally, the window glass of the motor vehicle tends to be widened in the right and left directions, which needs a wider wiping area (window wiping rate) accordingly. As the width of the window in the right and left directions increases, the projecting positions of the pivot shafts on the outer edge side of the window become further offset outwardly in the right and left directions of the vehicle body.
Thus, on the outer edge side, not only is difficulty encountered in securing the mounting sections of the pivot holders to the vehicle body at the outsides of the pivot shaft positions in the right and left directions, but also, even if securable, the fixing of the mounting sections with bolts becomes difficult since the mounting sections are positioned at end portions of the vehicle body.
SUMMARY OF THE INVENTION
The invention has been developed in order to eliminate these problems in consideration of the above-described situations.
In accordance with the invention, there is provided a wiper apparatus including right and left hand pivot shafts and a wiper motor that are incorporated into an integrated modular type holder member, wherein a mounting section formed on one pivot shaft side of the holder member is formed to extend outwardly, and provided on the bracket attached to the vehicle body are an insertion hole accepting the mounting section loosely in a state where the mounting section is tilted with respect to an incorporating or mounting posture of the holder member and a supporting portion for supporting the holder member, the holder member coming into contact with the supporting portion and pressed against one side edge of the insertion hole to be supported on the supporting portion when the holder member is inserted and takes the mounting posture.
Thus, according to the invention, for mounting a wiper apparatus to a vehicle body, there is no need to fix one pivot shaft side of the holder member with a bolt, but it is simply a matter of the insertion of the mounting section into the insertion hole, and the upper edge side of the mounting section moves to an upper edge side of the insertion hole by using, as a supporting point of a lever, a portion of the holder member coming into contact with the supporting portion when the holder member is shifted from the tilted posture to the mounting posture, so that the mounting section can be supported in a state of being pressed against both the insertion hole and the supporting portion, thus achieving firm assembling.
In addition, the insertion hole has a non-circular configuration and the side of the insertion hole against which the mounting section is pressed has a smaller dimension than the mounting section. Accordingly, the rotation of the mounting section is preventable, and since the insertion hole width reduces toward the upper edge side, the mounting section can be supported in a state of being cut or bitten thereinto, thereby preventing the occurrence of play.
