Abstract

PURPOSE:To enable the cancellation of all dispersing elements typical of a transmitting device with a relatively large final stage gear by disposing a friction gear with rotational resistance on an arm provided rotatably on the coaxial line with an intermediate gear and providing a driving gear always with constant energizing force. CONSTITUTION:The rotation of a motor 3 is transmitted to the pulley part 6a of a pulley gear 6 through a motor pulley 4 and a belt 5, and further onto a friction gear 9 from a gear part 6b. The gear 9 is then energized upward as shown by an arrow by a friction spring 13, so that friction is generated between the gear 9 and a slip-off stopper 10a. The rotational resistance by this friction generates the turning effort of an arm 8, and thereby the arm 8 is constantly energized in the A direction. On the other hand, as there is radial play between a driving gear 11 and a driving gear shaft 12, the gear 11 is constantly energized toward the gear part 1a of an internal tooth gear 1 by the energizing force of the arm 8, so that the gear 1 and the gear 11 are constantly brought into contact mutually in standard pitch circles, thus performing the transmission of torque.
