屈曲疲労性に優れた歯付ベルト、多リブベルト等の動力
伝動用ベルトに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to power transmission belts, and more particularly to power transmission belts such as toothed belts and multi-rib belts that have excellent water resistance and bending fatigue resistance.
（従来の技術）
歯付ベルトは平ベルトや■ベルトと異なり滑りのない確
実伝動が可能であり、また歯車やチェーンの確実伝動に
比べて給油を必要としない等の利点を有している。一方
、多リブベルトは■ベルトに比べて厚さが小さくて可塑
性を有し、そして背面駆動も可能であるところから小径
ブーりをもつ多軸駆動において使用されている。そのた
め、これらのベルトは特に自動車の伝動装置への進出が
顕著である。(Prior Art) Unlike flat belts and belts, toothed belts are capable of reliable transmission without slippage, and have the advantage that they do not require lubrication compared to reliable transmission using gears or chains. On the other hand, multi-rib belts are thinner and more flexible than belts, and can also be driven from behind, so they are used in multi-shaft drives with small diameter bobbins. Therefore, these belts are particularly popular in automobile transmission devices.
ところが、これらのベルトは、高湿、高負荷で且つ多軸
で使用されるため、屈曲疲労を受けてベルト切断を起こ
し易い条件下にある。特に、雨天の場合、水分はベルト
抗張体の疲労劣化をまねき、この結果ベルトの強力低下
は著しく、ベルトの切断が起こり易（なっている。However, since these belts are used under high humidity, high load, and multiple axes, they are subject to bending fatigue and are susceptible to belt breakage. Particularly in the case of rainy weather, moisture causes fatigue and deterioration of the belt tensile member, resulting in a significant decrease in belt strength and making the belt more likely to break.
ところで、今日かかるベルトの抗張体の１つとして強力

したコーＦ″）で、上１熱りと下撚りがかかっている。Nowadays, glass fiber ropes or cords (hereinafter simply referred to as cords), which have high strength, elongation, and small temperature changes, have been proposed as one of the tensile materials for such belts. For example, in the case of belts in automotive OHC drives, the glass fiber cord construction is typically ECG-15
0-3/13 (filament diameter is 9μ, size is 15
Collect 3 strands of 1,000 yards/lbs and pre-twist them to make a rope, and collect 13 of these ropes to make a rope F''), which is then twisted and twisted. .

たものが使用されている。Furthermore, a plurality of pre-twisted glass fiber strands are converged, and an upper twist is applied to them in the same direction as the pre-twisting,
A code has also been proposed in which the final twist coefficient is 0.06 to 1.50 and the final twist coefficient is 1/4 to 1/2 of the above-mentioned upper 1 coefficient. The glass cord used in each of these proposals is treated with resorcinol-formalin-latex (hereinafter referred to as RFL) in order to improve adhesion to the rubber compound.

ードが加水分解を起こすため、接着力の低下及びベルト
の強力が著しく低下することがあった。(Problem to be Solved by the Invention) However, when such a belt is run under high load conditions under multiple axes of small diameter pulleys, the glass fiber cord treated with RFL loses its resin content during use. As the solidification of the RFL progresses or the deterioration of the latex content progresses, the glass fiber cord may become hard and have poor bending fatigue resistance.Furthermore, if the RFL and the glass fiber cord are run under high temperature and humidity in the rain, the RFL and the glass fiber cord may be hydrolyzed. This may cause a decrease in adhesive strength and a significant decrease in the strength of the belt.

The object of the present invention is to provide a power transmission belt having the following characteristics.
