Zusammenfassung:	A mechanical reduction gear system is of the type comprising an external gear (16) which is rotatable about an eccentric revolving shaft (14) and an internal gear (18) which is engaged with the external gear (16). The contact ratio and operating contact during the actual loading operation are improved by constructing the system so that an external gear (16) has a tooth profile curve which is an addendum tooth profile curve at the outside of a pitch circle and an epicycloid curve, for example, such as that generated on the basis of a rolling circle or generating circle having a tooth number slightly fewer than the pitch circle and has a predetermined pressure angle on the pitch circle, and an internal gear has a tooth profile curve, for example, such as that generated on the basis of the tooth profile of the external gear.
