A flex splineused for a meshing type gear device includes an attachment portion, a thin-thickness tubular portioncontinuing to the attachment portion and capable of being elastically deformed, and external teethformed at the tip end portion of the tubular portion away from the attachment portion. The thin-thickness tubular portionis formed in a conical shape with an opening angle &#x3b8; which is tapered in a direction from the attachment portiontoward the external teethbefore inserting a wave generator

Since the phases of pinions,and a pinion,are deviated by 180 degree, the pinions,are acted with the engaging force which is reverse in a working direction to the engaging force of the pinion,and is half in the value. At this time since distances between a center,in the gear width of the pinion,and centers,in the gear width of the pinions,are substantially equal, the engaging forces in the pinions,and,are zero in resultant force and moment of rotation, and balanced.
