TECHNICAL FIELD

The present disclosure relates to a step motor and an indicator instrument for a vehicle.

BACKGROUND ART

Conventionally, a step motor has been widely used to drive a rotary body to rotate. For example, the rotary body is a rotating indicator indicating a vehicle state value, and is driven to rotate by a step motor.

SUMMARY

According to an aspect of the present disclosure, 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, and opposing the top portion through an axial gap at an outer circumference side of the insertion hole.
