Abstract

A step motor that rotationally drives a rotating body includes: an output gear having an output shaft that rotates around a rotation center line together with the rotating body, and a final gear extending radially outward from the output shaft; a radial bearing having an inner circumference side that radially supports the output shaft, on one side of the final gear in an axial direction; a reduction gear mechanism having a first reduction gear meshed with the final gear, and a second reduction gear meshed with the first reduction gear on the one side of the final gear in the axial direction; and a protrusion protruding from the radial bearing toward the other side in the axial direction, in a specific area extending from a longitudinal cross section of the output gear including the rotation center line to an opposite side away from the first reduction gear.
