When the gears are meshed and driven by an inclined shaft that rotates with respect to the base shaft, an axial thrust is generated in each gear, so the bearing structure becomes a problem. The present invention relates to a gear device that minimizes this thrust by changing the tooth profile.゛The drawings will be explained by taking an example in which the present invention is applied to a transmission. The input shaft 6 rotatably supported by the lid A of the case 5 consists of a base 6a and a bent part 6b, with the gear 1 being rotatably supported by the base 6a, and the gears 2 and 3 being rotatably supported by the bent part 6b. be done. Gear 1 is stopped from rotating towards lid A, and gear 2,
3 is fixed on the back and is integral. The output shaft 7 is rotatably supported by a hinge B on the same axis as the base 6a, and the gear 4 is fixed thereto. Gears 1 and 2 and gears 3 and 4 are in a meshing relationship. Transmissions with the above structure to obtain a large gear ratio are known, but in the present invention, one of the gears 1 and 2 has a tooth profile with a semicircular cross section, and the other gear has a symmetrical shape that can mesh with this. It consists of two circular arcs. The same applies to the teeth of gear 3.4. In Figure 2, gear 1 is semicircular, gear 2
An example is shown in which the shape is made into a synthetic circular arc shape.

It is relatively large compared to the one of the present invention shown in FIG. 71flJ In the gear of the present invention, the component force C in the pitch circumferential direction becomes large, and the thrust force in the axial direction becomes small. Since the gear ratio that can be obtained with this type of transmission is extremely large, the thrust is beyond imagination.
