Abstract
A step motor that drives a rotary body to rotate includes: an output shaft that outputs a rotational driving force to the rotary body, the output shaft having an insertion hole in which the rotary body is arranged so as to be integrally rotatable on an inner circumference side of a top portion of a tip end of the output shaft; a radial bearing radially supporting the output shaft from an outer circumference side; and a cover protruding from the radial bearing radially inward. The cover opposing the top portion through an axial gap at an outer circumference side of the insertion hole. The output shaft has an inner tapered portion which decreases in diameter as approaching the insertion hole radially inward from the top portion. The cover opposes the top portion through the axial gap at an outer circumference side of the inner tapered portion.
