PURPOSE:To reduce the gearing noise of intermittent interlocking by arranging a dog clutch between the clutch body and the output rotary body while arranging a clutch returning cam between the clutch body and the non-rotatable cam body. CONSTITUTION:A clutch body 3 to be engaged through dog clutches 5, 6 with a rotatable output rotary body 4 is engaged through clutch returning cams 8, 9 with a cam body 7 not rotatable against the input shaft 1. An intermittently rotatable cam 22 gearable with the output rotary body 4 while interlocked with the cam 12 to rotate intermittently is provided on the interlocking shaft 15. Upon rotation of the input shaft 1, the clutch body 3 will approach/separate against the cam body 7 for every constant rotary angle thus to rotate the output rotary body 4 easily and intermittently by predetermined angle through the dog clutches 5, 6, an intermittent rotary cam 22 and the cam 12, resulting in reduction of gearing noise to be produced through intermittent interlocking of predetermined rotation. |
