Claims

[Scope of utility model registration request]

A reduction gear train is provided between the rotor shaft and the output shaft of the rotor, and the reduction gear shaft is provided at both ends of a cylindrical reduction gear shaft into which the gears of the reduction gear train are loosely fitted. A shaft support plate having a circular shaft hole that fits and supports the end portion, and an oil reservoir plate arranged in parallel with at least one of the shaft support plates and holding lubricating oil in an oil reservoir gap between the shaft support plate and the shaft support plate. In the Warren motor, at least one end of the reduction gear shaft is provided with a knurled portion on its circumferential surface, and the oil sump gap is formed between the knurled portion and the inner periphery of the shaft hole, and the reduction gear shaft is loosely fitted therein. A waren motor characterized in that an oil passage is formed in a gap between the reduced gear and the reduced gear.
