A transmission gearing in which an eccentric cam includes first and second eccentric cam parts and a cam follower has contact faces abutting these eccentric cam parts so that, when a driving source rotates either in normal or reverse direction, the gearing provides as an output one of two different directional motions at the cam follower, with either one of the first and second eccentric cam parts positioned concentric with their pivot shaft without shifting the cam itself in diametral direction in gearing casing. The gearing arrangement is thereby simplified and minimized in required mounting space so as to realize a high compactness of the gearing. |
