To reduce noise of a gear.SOLUTION: A gear structure comprises: a shaft part 32 connected to a rotational shaft; a plurality of engagement surfaces 34 provided radially outward with respect to the shaft part 32, and arrayed in a rotational direction; and a connection part 36 positioned between the engagement surface 34 and the shaft part 32, and whose rigidity is different between one side and the other side in an axis direction of the rotational shaft. In at least one of the connection part 36 of a drive gear 10 and a connection part 46 of a driven gear 20, rigidity is made different between one side and the other side in the axis direction, so that noise of the gear can be reduced.SELECTED DRAWING: Figure 4 【課題】歯車の騒音を改善する。【解決手段】歯車構造は、回転軸に接続される軸部３２と、軸部３２よりも径方向外側に設けられ、回転方向に配列された複数の噛合い面３４と、噛合い面３４と軸部３２との間に位置し、回転軸の軸方向の一方側と他方側とで剛性が異なる接続部３６と、を備える。駆動歯車１０の接続部３６および従動歯車２０の接続部４６の少なくとも一方において、軸方向の一方側と他方側とで剛性を異ならせることにより、歯車の騒音を改善することができる。【選択図】図４
