Abstract
In a roller type transmission device, an arrayof transmission pin rollers is press fit circularly into an inner side surfaceof a stationary ring, and an arrayof controllable pin rollers is press fit circularly into an inner side surfaceof a rotational ring. To pin rollers, employed are high precision cylindrical rollers or needle rollers which are usually used for a roller bearing or the like. Such is the structure that the arrayof transmission pin rollers and the arrayof controllable pin rollers work as inner teeth to make a backlash phenomenon minimum, rendering a pitch distance precise between the pin rollers, maintaining a uniform tooth profile with a high precision, equalizing a surface roughness and improving a meshing precision between the pin rollersand the teeth
