く採用される様になってきた。(Technical disadvantages and problems of the invention) Recently, pulleys used for chassis or power transmission are made of metals such as iron, aluminum, and brass, and can be mass-produced at a low cost.
Cheap synthetic 4 resins such as nylon resin and ABS resin are increasingly being used.

電電流がヘッドから増巾回路を通してスピーカーから不
快音として発生する事がしばしば生ずる。By using this synthetic resin pulley, for example, in the case of a tape recorder, while the tape is running, static electricity or V is gradually accumulated on the pulley due to frictional charging between the belt and the pulley, and when this becomes saturated, a discharge phenomenon occurs. At this time, the discharge current often passes from the head through the amplification circuit and generates an unpleasant sound from the speaker.
特にこの現象は、金属プーリより合成（創脂プーリの方
が著しい、又ベルトとプーリとの駆動時の摩擦音も不快
音として発生する。In particular, this phenomenon is more pronounced with synthetic pulleys than with metal pulleys, and also causes unpleasant friction noise when the belt and pulley are driven.
この欠点を除くためにゴムベルトに導電性を与える工夫
及びゴムベルトの表面摩ｌ寮係数を下げる工夫か種々成
されている。In order to eliminate this drawback, various efforts have been made to make the rubber belt conductive and to lower the surface friction coefficient of the rubber belt.

ティングする方法か知られている。For example, conductive carbon black powder, gold powder, or antistatic agents have been mixed into raw rubber, and two low-friction materials have been used as a means of lowering the surface friction coefficient of a rubber belt. A method of coating with molybdenum sulfide and fluororesin is known.
然るにベルトに導電性を与えたものはベルトの表面抵抗
値がバラついたり、ベルトの所要物性が低下する場合も
あり、低摩擦材質をコーティングする方法は工数も多く
なりコストも高くなる欠点がめった。However, if the belt is made conductive, the surface resistance value of the belt may vary or the required physical properties of the belt may deteriorate, and the method of coating the belt with a low-friction material has the disadvantage of increasing the number of steps and cost. .
