Claims

[Scope of utility model registration request]

A first cam 12 having a convex curved partial arc shape with the gear axis of the driving side partial gear 11 as the center of curvature is installed in the gear tooth non-forming phase of the driving side partial gear 11 which has gear teeth 11b formed on a part of its circumferential surface. is provided so as to be able to rotate integrally with the driving side partial gear 11 by being offset in the direction of the gear axis of the driving side partial gear 11, and the driven side gear 13 is capable of meshing with the gear teeth 11b, 11c of the driving side partial gear 11. , the second cams 14a, 14b having the same curvature as the first cam 12 and having a concave arc shape are deviated in the direction of the gear axis of the driven gear 13.
3, and the gear teeth 11b, 11c of the driving side partial gear 11 mesh with the gear teeth of the driven side gear 13, so that the driven side gear 13 is rotationally driven, and the driving side partial gear 11 The second cams 14a, 1 are arranged so that a stopped state in which the first cam 12 of the driven gear 13 engages with the second cams 14a, 14b of the driven gear 13 and the driven gear 13 is stopped and held is alternately displayed.
Intermittent gear transmission structure with 4b phase setting.
