A motion assist device for assisting a motion such as a walking motion of a user includes: a pair of femoral part support units (3L, 3R) configured to be worn by two femoral parts of a user, a single power source (4, 70) for producing power and a power transmission unit (20; 60; 91, 92) for transmitting the power of the power source to the femoral part support units as an opposite phase motion, wherein the power transmission unit includes a differential unit (22; 63, 64; 93, 94) for accommodating a same phase motion of the two femoral part support units. The device may further include a control unit (5) configured to actuate the power source when the femoral part support units are undergoing the opposite phase motion, and to keep the output end of the power source stationary when the femoral part support units are undergoing the same phase motion. |
