<p>The invention relates to friction drive belt which is particularly adapted for driving, for example, auxiliary machines of an automobile engine (e.g., a cooling fan). This belt is made of a vulcanized rubber composition comprising a highly saturated nitrile rubber having an iodine value of up to 60, zinc methacrylate and an organic peroxide. This belt has better oil resistance, heat resistance, low-temperature resistance and mechanical strengths than those of conventional belts and, in addition, possesses a markedly improved bending resistance which has been insufficient with any of the conventional belts.</p> |
