The invention relates to a rotary swash plate type continuously variable transmission, which comprises a driving mechanism, an output mechanism and a casing 24. Said driving mechanism comprises a rotational swash plate 9 with variable angle of inclination and at least three slide stems which are disposed parallel and equiangular with each other. Each slide stem is equipped with a one-way rotary bevel wheel 13 at one end, and contacts with and slides on the surface of the swash plate at the other end. Said output mechanism comprises a one-way rotational output shaft 16 and a larger bevel wheel 14 which is disposed on the output shaft 16 and meshed with the bevel wheels 13. The transmission according to the invention is compact in view of structure and smooth in view of its output rotational speed. Axial lines of the input shaft and the output shaft may be coincident so it can be a coaxial continuously variable transmission. Moreover, the minimal rotational speed may be zero.
