ABSTRACT:
A geared motor comprising a rotating axle rotating in accordance with the rotation of a rotor, a gear rotating axle for outputting from the rotating axle speed reduced rotation, and a flexible coupling consisting of a first coupling disposed on the rotating axle of the rotor and rotating together with the rotating axle and the rotor, a second coupling disposed on the gear rotating axle, and rotating together with the gear rotating axle, a rubber damper disposed between the first coupling and the second coupling for transmitting the rotation of the first coupling to the second coupling, a thrust-force bracing member disposed between the rotating axle of the rotor and the gear rotating axle and in contact with the rotating axle and the gear rotating axle, for transmitting thrust force from one of the rotating axle of the rotor and the gear rotating axle to the other of the two arranged so that even if thrust force acts on the rotating axle of the rotor or on the gear rotating axle, the thrust force does not act on the first and second couplings or the rubber damper, due to the thrust force bracing member. Therefore, the life-expectancy of both of the couplings and the rubber damper, and therefore of the flexible coupling, is improved.
