A motion converting drive mechanism (64) converting a rotary motion into a linear reciprocating motion includes a motor (66) having an output shaft (66a), a housing case (76, 95) to which the output shaft (66a) is fixed, a reduction gear mechanism (67A, 67B) including a first pinion (72) and a second pinion (73, 91) meshing with the first pinion (72), and a screw mechanism (68A, 68B) having an internal threaded portion and an external threaded portion, one of which is integrally and coaxially formed with the second pinion (73, 91). The first pinion (72) as a helical gear wheel is supported by the housing case (76, 95) and has a rotation axis coaxially connected to the output shaft (66a). The second pinion (73, 91) having a rotation axis arranged in parallel and close to the rotation axis of the first pinion (72) is supported by the housing case (76, 95).
