A motor-incorporated hypocycloid-type speed reducer includes: a motor housed in a case; a first larger internal gear; a second smaller internal gear coaxial with a motor shaft; an output shaft coaxial with the motor shaft, the output shaft being provided with the second internal gear; and an external gear. A motor core of the motor is provided with an eccentric portion eccentric to the motor shaft at a predetermined degree. The external gear, which has a first external gear engaged with the first internal gear and a second external gear engaged with the second internal gear, is further provided with a rotor-receiving portion rotatable integrally with the eccentric portion of the motor core. The rotor-receiving portion is coaxial with the first external gear and the second external gear.
