構造。 A rotor shaft integrally formed with a rotor pinion portion, a magnet loose fitting portion, and a tapered portion whose diameter decreases toward the magnet loose fitting portion, and a rotor shaft having a hole that loosely fits into the magnet loose fitting portion of the rotor. The rotor shaft is composed of a cylindrical rotor magnet of a metal type, and a flat spring seat that fits into the tapered part of the rotor shaft and whose center hole diameter has a spring property that allows it to expand and contract in a plane direction. The rotor magnet is clamped and fixed to one side of the rotor pinion portion by loosely fitting the rotor magnet into the loose fitting portion and press-fitting the spring seat into the tapered portion of the rotor shaft. Features the rotor structure of a watch step motor.
