When a design point is given in the coordinate system Cs which consists of the line of centers and the axis of the relative angular velocity, it is discussed how the inclination angle of a straight path of contact go which coincides with the contact normal and realizes no variation of bearing loads should be chosen to have smooth tooth surfaces around the design point. When the design point coincides with the limit of action, the go is denned as the limit path of contact which varies due to the selection of the axis of generating gear. Therefore in this paper, the following two cases are discussed. In the case where the axis of generating gear coincides with that of the mating gear, which means the generated tooth surfaces make a line contact, there are a pair of limit paths of contact gis and 02s whose limits of action coincide with the design point corresponding to gears I and II. In the other case where the axis of generating gear is parallel to that of each generated gear, which means the generated tooth surfaces make a point contact, there are a pair of limit paths of contact g＼k and g-ih whose limits of action coincide with the design point corresponding to gears I and II. A path of contact fifo must be inclined adequately from those limit paths of contact to have smooth tooth surfaces around the design point.
