PROBLEM TO BE SOLVED: To dispense with a mounting means of a vibration damper and mount the vibration damper without constraint on a mounting position in a gear for damping the vibration by frictional force. SOLUTION: This vibration damping gear is composed of a gear body 1, and vibration dampers 2A, 2B mounted on the gear body 1. The vibration damper is made of a circular member engaged with the gear body and free from a cut in the circumferential direction, and fixed on the gear body by the friction bonding of a fitting part Z by press fitting, shrinkage fitting, hardening strain after fitting or the like, and the vibration produced by the fitting is absorbed by the friction between the gear body and a joint part of the vibration damper.
