<P>PROBLEM TO BE SOLVED: To provide a planetary differential type motion converting mechanism, in which biased abrasions and defects caused due to a tilt state of a planetary shaft can be restrained from occurring in screws and gears formed in the planetary shaft and occurring in screws and tooth faces of the gears engaged with these screws and the gears. Ž<P>SOLUTION: A bearing hole 34, penetrating along an axial direction, is made in a planetary gear 32b on a rear side of the planetary shaft 30 and besides a shaft 33 extending along its axial direction is made in an intermediate portion 35 of the planetary shaft 30. Furthermore, In the shaft 33, a displacement restricting portion 40a for restricting a rear-side planetary gear 32b from being displaced so as to come closer to a sun shaft 20 is formed integrally with a cover 40 and a penetrated part 33a which is penetrated from the hole 34 so as to approach from the side of the sun shaft 20.
