Abstract

A gear set includes a first gear, and a second gear. Each tooth of the first gear includes a rigid tooth including a first acting tooth face that transmits motion to the second gear or to which motion from the second gear is transmitted and an elastic tooth provided away from the rigid tooth via a slit, configured to bend in a direction toward the rigid tooth when the elastic tooth meshes with the second gear, and including a first non-acting tooth face that contacts the second gear. A tooth thickness of each tooth of the first gear, the tooth thickness being a sum of a thickness of the rigid tooth, a width dimension of the slit, and a thickness of the elastic tooth of the first gear on a pitch circle of the first gear in a free state in which the first gear does not mesh with the second gear, is equal to or larger than a width of a tooth groove of the second gear on a pitch circle of the second gear, and a width of a tooth groove of the first gear on the pitch circle of the first gear is equal to or less than a tooth thickness of each tooth of the second gear on the pitch circle of the second gear.
