ABSTRACT:
A method for fabricating a rotational-to-linear motion conversion mechanism which can avoid a planetary shaft from being tilted with respect to a sun shaft when the conversion mechanism is assembled. The method includes fabricating a subassembly with the planetary shaft being held in parallel to the sun shaft. The subassembly includes the sun shaft having a first and second sun gear at its opposing ends and a male thread at its center, the planetary shaft having a first planetary gear at its one end and a male thread at its center, a ring shaft having a female thread, and a first and second ring gear. The method also includes mating the second planetary gear with the second sun gear and the second ring gear while the second planetary gear is being fitted over the outer circumferential surface of the other end of the planetary shaft in the subassembly.
