ABSTRACT:
A motion converting drive mechanism converting a rotary motion into a linear reciprocating motion includes a motor having an output shaft, a housing case to which the output shaft of the motor is fixed, a reduction gear mechanism including a first pinion and a second pinion meshing with the first pinion, and a screw mechanism having an internal threaded portion and an external threaded portion, one of which is integrally and coaxially formed with the second pinion. The first pinion serving as a helical gear wheel having two to four teeth is rotatably supported by the housing case therein. The first pinion has a rotation axis rotatably and coaxially connected to the output shaft of the motor. The second pinion having a rotation axis arranged in parallel and close to the rotation axis of the first pinion is rotatably supported by the housing case therein.
