PROBLEM TO BE SOLVED: To improve a durable strength against a work load and miniaturize an intermittent driving mechanism, and provide an intermittent gearing mechanism by which a dividing number can be set optionally, and an improvement of a suspension precision of a driven rotor can be aimed at the suspension time of the rotation. SOLUTION: A driven rotor 3 is equipped with an arc-shape nonpassible hollow part 1 and a passive engaged part 2. A driving rotor 6 is equipped with an engaging part 4 which engages with the engaged part 2 and gives an intermittent driveing rotation to the driven rotor 3 at a prescribed angle, and a cam part 5 equipped with a rotation-regulating surface 5a which relatively moves along an arc-shaped surface 1a of the nonpassible hollow part 1 at the suspension time of the driven rotor 3. The engaging part 4 and the engaged part 2 are positioned differently to each other in the axial direction of the rotary shaft center relative to the rotation-regulating surface 5a and the nonpassible hollow part 1, and the engaged part 2 is composed of a gear around which a tooth part 2a is formed with a prescribed pitch, and also the engaging part 4 is composed of a partial gear equipped with a tooth part 4a meshing with the gear. |
