<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a rotational-linear motion converting mechanism capable of preventing a planetary shaft from being assembled in a state of being tilted with respect to a sun shaft when assembling the rotational-linear motion converting mechanism. <P>SOLUTION: Of processes A to J for manufacturing the rotational-linear motion converting mechanism, an assembly S comprising the sun shaft 3 having front face and back face sun gears 32 and 33, a planetary shaft body 41 having a front face planetary gear 42, a ring shaft body 21, and front face and back face ring gears 22 and 23 is assembled till the process I. During assembling of the assembly S, the planetary shaft body 41 is maintained to be parallel with respect to the sun shaft 3. In the process H, a back face planetary gear 43 is inserted to a back face shaft of the planetary shaft body 41 of the assembly S. At that time, the back face planetary gear 43 rotates and is meshed with the back face sun gear 33 and the back face ring gear 23. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
