A small diameter hysteresis magnetized material is provided on the opposite side of the mounting disk from the inner diameter hysteresis magnetized material plate, and the small diameter hysteresis magnetized material is closely opposed to the permanent magnet small wheel plate so as to be held by the magnetic force of the permanent magnet small wheel plate. The small-diameter hysteresis magnetized material plate and the permanent magnet small wheel plate constitute a magnetic coupling for position holding, and the position of the deceleration drive system during rest is determined by the magnetic force coupling for position holding. An electric point machine characterized by being equipped with a linking shaft device that can be held.
