Abstract

A guide device for an endless torque-transmitting member. The guide device includes at least two corresponding guide tongues between which the endless torque-transmitting member is at least partially guided. The guide tongues are held at a predetermined distance from each other by a connection region. The distance between the guide tongues is maintained substantially constant when there is a temperature change by the use in the guide device of materials having different coefficients of thermal expansion. A mold for producing a guide device is disclosed and includes two corresponding mold halves, where at least one connecting component formed from a material having a lower coefficient of thermal expansion than that of the guide tongues is held in one mold half.
