SPEED REDUCTION MECHANISM, MOTOR WITH SPEED REDUCTION MECHANISM, AND METHOD FOR PRODUCING SPEED REDUCTION MECHANISM

摘要

According to the present disclosures, in the type of speed reduction mechanism of which, by means of rotation under conditions wherein the angle of obliquity of a worm and a worm wheel are the same as each other, the number of meshed teeth is normally n+1 or varies between n+1 and n (where n is a natural number), the angle of obliquity of the worm is set to be greater than that of the worm wheel in a manner so that the maximum number of meshed teeth becomes no greater than n.
