PROBLEM TO BE SOLVED: To provide a design device for a gear pair easily setting design information for efficiently machining the excellent gear pair for practical use with a high yield. SOLUTION: An arithmetic part 6 sets a plurality of patterns of tooth surface correction amount groups G each comprising a combination of values of respective tooth surface correction amounts, simulates a plurality of patterns of the gear paris capable of being produced within a machining error range when performing tooth surface machining by use of elements wherein each tooth surface correction amount is imparted to a basic elements in each tooth surface correction group G, and calculates tooth surface error distribution information of each tooth surface in each gear pair. Each transmission error amount E under a plurality of meshing conditions is calculated to all the gear pairs simulated within a set machining range in each tooth surface correction amount group G based on each corresponding tooth surface error distribution information, and the optimal tooth surface correction amount group is extracted. At that time, an installation error amount D occurring according to torque Tq is calculated in each prescribed torque based on a displacement amount of each gear in a meshing model, and the installation error amounts D are used as the meshing conditions.
