ABSTRACT:
The invention relates to a torque metering device for a bicycle-type ergometer, in which ergometer the braking force is steplessly adjustable and in which the rotating movement is compensated by means of a flywheel. The rotating movement of the flywheel can be braked by means of a belt (5) which is pressed against the outer periphery of the flywheel and moves limitedly with the flywheel. The movement of the belt (5) with the flywheel is restricted by means of a spring member (6) connected to one end of the belt and the frame structure of the ergometer. In order to provide a reliable and easily readable metering device, the device is so constructed that it comprises a pin member (7) fastened on the belt (5) and means (8) for rotating an indicator (10) journalled for rotation. The rotating means (8) of the indicator are journalled on the frame structure (1) at the central portion thereof. One end of the rotating means (8) of the indicator is connected to the pin member (7), the other end being correspondingly secured on a shaft (12) of the indicator (10) in such a manner that a linear movement of the pin member (7) moves one end of the rotating means around the journalling point (11) of said means, thus effecting a corresponding rotating movement of the other end of the rotating means (8), which movement turns the indicator (10).
