A rotary power transmission apparatus for transmitting a rotary power from an input rotary member (1) to an output rotary member (8) eccentric from the input rotary member. The rotary power transmission apparatus comprises: a ring member (6) arranged around the outer circumferences of the input rotary member and the output rotary member and made rotatable on an axis (06) eccentric from those (01,08) of the input rotary member and output rotary member; a first intermediate rotary member (3) for transmitting a torque between the input rotary member and the ring member; a second intermediate rotary member (7) for transmitting the torque between the ring member and the output rotary member; and a relative phase changing mechanism (4,5,10,11,12) for changing the relative phases in the direction of revolution between the first intermediate rotary member and the second intermediate rotary member along the inner circumference of the ring member. <IMAGE> |
