Abstract
In a bevel gear pair, a first gear and a second gear are applied with tooth top modification, and a ratio of a distance from a pitch circle to a starting position of the tooth top modification to a distance from the pitch circle to a tooth top in the first gear is larger than a ratio of a distance from a pitch circle to a starting position of the tooth top modification to a distance from a pitch circle to a tooth top in the second gear. Thus, the bevel gear pair that can achieve smooth meshing is provided.
