歯車構造。[Claims for Utility Model Registration] (1) A first shaft, a plurality of external gears eccentrically attached to the first shaft via an eccentric body provided on the first shaft, and the external gears. An internally meshing planetary gear structure comprising an internal gear with which the gears internally mesh, and a second shaft connected to the external gear via a means for transmitting only an autorotation component of the external gear, The first shaft and the eccentric body are coupled so as to be displaceable in the radial direction within a range that does not impair the internal meshing rotation function of the external gear, and the first shaft of the eccentric body is connected to the first shaft. An internally meshing planetary gear, characterized in that a positioning member is attached to the shaft that can restrain the axial movement of the body and can receive the moment when the eccentric body tends to tilt with respect to the axis of the first shaft. structure. (2) The external gear is fitted to the eccentric body through two angular bearings arranged such that lines of action of the bearings face each other. The internal meshing planetary gear structure described.
