Abstract

See full text

This gear wheel mechanism includes a rotator, a first gear wheel, a second gear wheel, and a reinforcement member. The rotator is configured to be rotatable about a rotation shaft and has an elliptical shape as viewed in an axis direction of the rotation shaft. The first gear wheel includes a first base portion including a first outer circumferential surface and a first inner circumferential surface and having a hollow cylindrical shape configured to be deformable by the rotator being inserted in the axis direction of the rotation shaft and external teeth formed in the outer circumferential surface. The second gear wheel includes a second base portion including a second outer circumferential surface and a second inner circumferential surface and having a hollow cylindrical shape disposed to cover the external teeth and internal teeth which are formed at positions facing the external teeth of the second inner circumferential surface, with which the external teeth are partially engaged in accordance with deformation of the first base portion by rotation of the rotator. The reinforcement member is disposed in contact with a region of the second outer circumferential surface corresponding to a region in which the internal teeth of the second inner circumferential surface are formed.
