Claims

[Scope of Claim for Utility Model Registration] A main gear fixed to a rotating shaft, a sub-gear that overlaps the main gear and is movable relative to the main gear, and a connection between the main gear and the give gear. A space is provided between the main gear and the sub gear, the spring is housed in the space, and mounting holes are provided at both ends of the spring, The spring is attached to the main gear and the sub gear by loosely fitting its attachment hole into a pin fixed to the main gear and the sub gear, and the spring is attached to the center of the rotating shaft. An oil passage for supplying oil to the journal portion is provided, and a scissor gear is provided in which an oil hole communicating with the oil passage is bored on the surface of the rotating shaft that the sub-gear is in contact with. A gear device equipped with a scissor gear, characterized in that the gear device includes an oil supply means for supplying oil from the oil passage to a space between the main gear and the sub gear.
