摘要： PROBLEM TO BE SOLVED: To provide a stepping motor capable of preventing a motor function from being damaged, even under a high-temperature environment or under situations where frictional heat is generated during high-speed rotation.
SOLUTION: The stepping motor 1 has a constitution, where a magnet 6 is fixed to the outer peripheral face of a sleeve 4 mounted on an output shaft 3; a rotor 2, to which the magnet 6 is fixed, is arranged freely rotatable with respect to the inner periphery of a stator 10; a holder 21 formed, by loosely fitting a cup-shaped base 22 and a cap 23 and storing a coil spring 24 in its inside; the holder 21 is interposed between a bearing 9, which supports the output shaft 3, and the sleeve 4; the holder 21 is formed of a reinforced polyamide resin; and a member of proper slidability is interposed between the holder 21 and the bearing 9.
