PURPOSE:To steeply reduce the axial size of a whole device by fixing a flexible spline to a housing so as to extract the rotating power from a ring-like circular spline. CONSTITUTION:This prime mover outputs the power for a liquid-operated motor 1 via a harmonic reduction gear 2. The liquid-operated motor 1 has a support shaft 3 with an eccentric section 3a and a casing rotatable around the axis center O1 of this support shaft 3. A ring-like circular spline 22 is rotatably supported on the inner circumference of a cup-like housing, and a wave generator 25 is arranged inside this circular spline. The flexible spline 24 of the harmonic reduction gear 2 is fixed to the housing holding the support shaft of the motor 1 and extracts the rotating power from the circular spline 22. |
