Abstract:
A transmission provided with an input shaft and an output shaft supported on a first axis as to freely rotate, comprising:a transmission eccentric shaft having a declination axis crossing the first axis at a predetermined angle, mounted on the input shaft so as to freely rotate; a transmission input plate mounted on the transmission eccentric shaft so as to freely rotate around the declination axis and revolve around the first axis; an output eccentric shaft arranged on the declination axis, supported on an end portion of the input shaft on the output shaft side so as to freely rotate; a universal joint portion having a casing portion mounted on the output eccentric shaft so as to freely rotate around the declination axis and revolve around the first axis and which is provided with a revolution force around the first axis by contact with the transmission input plate, and a joint main body connecting the casing portion to the input shaft; the output shaft formed unitedly with the output eccentric shaft; and a transmission means rotating the transmission eccentric shaft to change a revolution speed of the transmission input plate.
