Driving motor

Provided is a driving motor that will meet the requests of making the length of a rotating axis of the driving motor to be shorter in the axial direction, and which will also have waterproof, vibration resistance, and soundproof characteristics. In this driving motor (3); a motor interior-space (35) is formed by a housing (21) that has a first and second opening and which is formed to be cylinder shaped, and a flange (22) that blocks the second opening of this housing (21); and a stator assembly (18), a rotor assembly (20), a lower-side end section of the rotating axis (12) that has been placed lower than the flange (22) up until now, and a control circuit-board (19) are all made to be contained in this motor interior-space (35). Furthermore, a ring-shaped elastic member (45) is made to interpose between the upper-side end section of the rotating axis (12) and the first opening of the housing (21); and the lower-side end section of the rotating axis (12), the stator assembly (18), and the rotor assembly (20) are made to be fixed to the flange (22) through a mounting elastic member (59).
