Disclosed herein is a compact motor with a speed reducing mechanism, including a cylindrical casing having an open end, a stator fixedly provided in the casing, an exciting coil provided in the casing, a rotor provided in the casing and having a high-speed output shaft on which a pinion is fixed, a cover for covering the open end of the casing, a low-speed output shaft projecting from a hole formed through the cover, and a reduction gear train interposed between the pinion and the low-speed output shaft for transmitting power to the low-speed output shaft. The compact motor further includes a lever connected to the low-speed output shaft; an eccentric cylinder formed integrally with a final gear of the reduction gear train and adapted to eccentrically rotate about a gear shaft for rotatably supporting the final gear; and a connecting member having one end pivotally engaging with an outer circumference of the eccentric cylinder and another end pivotally engaging with the lever. Accordingly, the low-speed output shaft itself can be oscillated. Further, in the event that an overload is applied to the low-speed output shaft during oscillation, breakage of the intermediate transmission members can be prevented, and an oscillatory position of the low-speed output shaft can be kept unchanged.
