ABSTRACT:
A flexible shaft coupling has first and second hubs, each of which is provided with flanges and connected to a transmission shaft. The flange of the first hub has spring holes extended therethrough. A cover is fixed to the second hub so that the flange of the first hub is held between the cover and the flange of the second hub, and the cylindrical part of the first hub extends through the cover. A plurality of coil spring sets each comprises multiple barrel-shaped coil springs. Each of the coil springs is supported in the spring hole so that the adjoining end faces thereof are in contact and in series with each other.
