Claim 11:
12. A speed reducing mechanism comprising:
a speed reducing unit for decelerating input rotation;
an accelerator for accelerating rotation from the speed reducing unit; and
a brake unit for applying a braking force to the accelerator,
wherein the speed reducing unit includes:
a center gear configured to rotate about a speed reducing central axis that constitutes a rotation center of the speed reducing unit;
an idler gear connected to the center gear;
a crankshaft integrated with the idler gear;
a cam provided on the crankshaft;
an external-tooth gear configured to oscillate and rotate around the speed reducing central axis by the cam; and
an outer cylinder including an internal-tooth gear meshing with the external-tooth gear and configured to rotate around the speed reducing central axis,
wherein the speed reducing mechanism further comprises:
a first output shaft rotated by the outer cylinder;
a second output shaft parallel to the first output shaft;
a first output gear and a second output gear connecting between the first output shaft and the second output shaft and configured to transmit rotation therebetween; and
another accelerator connected to the second output shaft and configured to accelerate an output of the speed reducing unit, and
wherein the first output shaft is connected at one end thereof to a rotational driving source for inputting a rotational driving force via the speed reducing unit,
wherein the first output shaft is connected at the other end thereof to the other accelerating unit via the first output gear and the second output gear,
wherein the first output shaft includes a tilting portion between the one end and the other end thereof,
wherein the speed reducing mechanism further comprises a leg portion rotatably supporting the first output shaft serving as a tilting shaft,
wherein the leg portion supports the second output shaft and the brake unit, and
wherein the other accelerator is braked by the braking force of the brake unit connected to the other accelerator.
