ABSTRACT:
A gear is provided with double rows of teeth having the same pitch circle, which are deviated from each other in the circumferential direction. The gear can be mutually engaged with another counterpart identical with no backlash between the meshed teeth, whereby a rotary motion can be efficiently and smoothly transmitted between the rotating gears engaged without involving vibrations and noises.
