Then, the left and right end portions 2a, 2b of the belt-like fixing member 2 are fitted and connected to the support 21 by bending inward.

従って、この帯状固定部材２の左右端部２ａ，２ｂは支持体21に面接触することになる。   Accordingly, the left and right end portions 2 a and 2 b of the belt-like fixing member 2 come into surface contact with the support 21.

本実施例は上述のように構成したから、本実施例に係るワイパー用加熱装置をワイパー20に取り付ける場合、発熱線１を払拭ラバー22の上端面に重合状態とし、この状態で帯状固定部材２で発熱線１の上部を覆い、両端部を払拭ラバー22の長辺端面としての正面部及び背面部夫々の長さ方向に配設された補強金属板部材23夫々と当接するようにして払拭ラバー22を帯状固定部材２で囲繞被嵌する。   Since the present embodiment is configured as described above, when the wiper heating device according to the present embodiment is attached to the wiper 20, the heating wire 1 is superposed on the upper end surface of the wiping rubber 22, and in this state, the belt-like fixing member 2 The wiping rubber covers the upper part of the heating wire 1 with both ends being in contact with the reinforcing metal plate members 23 arranged in the length direction of the front side and the back side as the long side end surfaces of the wiping rubber 22, respectively. 22 is enclosed by the band-shaped fixing member 2.

従って、発熱線１からの熱は、払拭ラバー22の上端面から伝わるとともに、帯状固定部材２及び補強金属板部材23を介して払拭ラバー22の内側（スリット部22ｂ内）からも伝わり、よって、熱が払拭ラバー22全体に良好に伝わることになり、しかも、発熱線１は払拭稼働時に変形しない（或いは変形の少ない）払拭ラバー22の上端面に設けられる為、発熱線１が払拭ラバー22から外れることはない。   Therefore, the heat from the heating wire 1 is transmitted from the upper end surface of the wiping rubber 22, and is also transmitted from the inside of the wiping rubber 22 (in the slit portion 22b) through the belt-like fixing member 2 and the reinforcing metal plate member 23. Heat is transmitted well to the entire wiping rubber 22, and the heating wire 1 is not deformed (or less deformed) during the wiping operation, and is provided on the upper end surface of the wiping rubber 22. It will not come off.

ところで、払拭ラバー22を加熱することで、例えば払拭ラバー22が柔らかくなり、この払拭ラバー22のスリット部22ｂに嵌合配設された補強金属板部材23が外れてしまうことが懸念されるが、この点、本実施例は、帯状固定部材２で補強金属板部材23を押えた状態となる為、この補強金属板部材23が外れてしまうことを確実に防止することができる。   By the way, by heating the wiping rubber 22, for example, the wiping rubber 22 becomes soft, and there is a concern that the reinforcing metal plate member 23 fitted and disposed in the slit portion 22b of the wiping rubber 22 may come off. In this respect, in this embodiment, since the reinforcing metal plate member 23 is pressed by the belt-like fixing member 2, it is possible to reliably prevent the reinforcing metal plate member 23 from being detached.

よって、本実施例によれば、低温環境下においてもワイパー20の機能を確実に発揮させることができる。   Therefore, according to the present embodiment, the function of the wiper 20 can be reliably exhibited even in a low temperature environment.

また、本実施例は、払拭ラバー22に設けられる既存の補強金属板部材23を利用して払拭ラバー22全体に良好に熱を伝える構造であるから、前述した作用効果を簡易な構造で確実に実現することができる。   In addition, since the present embodiment is a structure that transfers heat well to the entire wiping rubber 22 using the existing reinforcing metal plate member 23 provided on the wiping rubber 22, the above-described effects can be ensured with a simple structure. Can be realized.

また、本実施例の帯状固定部材２は、払拭ラバー22の長さ方向に間隔を置いて複数設けられるものであるから、簡易且つ確実に発熱線１を固定することができる。   Moreover, since the strip | belt-shaped fixing member 2 of a present Example is provided with two or more intervals in the length direction of the wiping rubber 22, the heating wire 1 can be fixed easily and reliably.
