Patent attributes
An anti-backlash structure for a scissors gear is provided including a scissors gear and a cam gear which are coaxially connected to rotate relative to each other, an end piece which has one side which is press-fitted into a cam shaft so that the end piece rotates together with the cam shaft, the other side which is in surface-to-surface contact with the scissors gear, and a circumferential surface with which the cam gear is press-fitted; a bolt which is coupled to an inner diameter portion of the scissors gear, penetrates the end piece, and is inserted into the cam shaft; and a scissors spring which has one side coupled to the end piece, and the other side coupled to the bolt. When the end piece rotates, the scissors spring rotates the scissors gear relative to the cam gear through the bolt and allows the scissors gear to come into close contact with the cam gear.
