An intermittent transmission apparatus according to this invention, broadly, includes a driving element (2) and a driven element (3). The driving element (2) comprises a first cam (4) having a first cam surface (4b), a second cam (5) having a second cam surface (5b), and an intermediate member (6) displaced between the first and second cams (4, 5). The driven element (3) comprises a driven element main body (10) having recesses (10a) for contacting a plurality of rollers (7) arranged on the intermediate member, bearings (12) erected on the driven element main body (10) to be pushed by the first cam surface (4b), and bearings (15) erected under the driven element main body (10) to be pushed by the second cam surface (5b). During non-drive periods of the driven element (3), the bearings (15) contact a circular arc surface of the second cam (5), and further the recesses (10a) contact the plurality of rollers (7), to restrict rotation of the driven element (3). <IMAGE> |
