PURPOSE:To improve the efficiency of power transmission mechanism by absorbing an angular backlash occuring in a power transmission part through the deflection of an arc-shaped sectional leg part extending from the end of the cylindrical part of a drive to accelerate response speed at the time of changing over the direction of rotation. CONSTITUTION:The spline plate of an external tooth gear mounted on an inlet shaft through an eccentric body is coupled universal joint-shapedly with the spline part of an output shaft through a drive 8. Said drive 8 has an arc-shaped sectional leg part 8B extending from the one end of a cylindrical part 8A, and the inner spline 6 of said cylindrical part 8A engages with the outer spline of the output shaft. Said leg part 8B is inserted through the through hole of the external tooth gear, and its inner spline 7 engages with the outer spline of the spline plate. Thus the deffection of the leg part 8B absorbs an angular backlash existing in a power transmission mechanism, and response speed can be therefore accelerated at the time of changing over the direction of rotation to improve the efficiency of the power transmission mechanism. |
