Abstract: Each of gear teeth of an external gear has a tooth-bottom portion, a tooth-middle portion and a tooth-front portion. The tooth-middle portion is operatively engaged with an internal gear. A cross-sectional shape of the tooth-bottom portion is formed by a hypocycloid curved line. A cross-sectional shape of the tooth-middle portion is formed by an epicycloid curved line. A cross-sectional shape of the tooth-front portion is formed by a first predetermined curved line, which is located at a position closer to a first pitch circle of the external gear in a radial-inward direction from a reference epicycloid curved line. The reference epicycloid curved line is continuously connected to each of the curved lines of the tooth-middle portion at both circumferential sides of each gear tooth. As a result, the tooth-front portion is so formed that a part of the tooth-front portion is escaped in the radial-inward direction from the reference epicycloid curved line.
