Claims

[Scope of utility model registration request]

One surface of a sub-gear having a different number of teeth from that of the main gear is slidably attached to the side surface of the main gear, and a stopper is disposed facing the other surface of the sub-gear, and the stopper and the sub-gear are arranged to face each other. In the friction gear device, the auxiliary gear is brought into close contact with the main gear by a disc spring interposed between the two gears to generate a necessary frictional resistance for relative rotation of the two gears, wherein the disc spring is in sliding contact with the auxiliary gear. a contact portion that contacts the auxiliary gear or the stopper on at least one of the edge portion and the sliding edge portion with respect to the stopper;
Non-contact parts and non-contact parts are provided alternately in the circumferential direction,
A friction gear device characterized in that a gap portion for guiding lubricating oil that expands toward the non-contact portion is provided at a boundary portion between the contact portion and the non-contact portion.
