To provide a gearless drive mechanism, facilitating the connection between an output shaft of a continuously variable transmission and a rotating shaft of a driven body, and transmitting the rotating speed of the output shaft to the rotating shaft of the driven body with good accuracy.
This gearless drive mechanism includes: an input shaft 4 rotating on receiving the driving force; an output shaft 5, one end of which is connected to the input shaft through a variable speed mechanism, the other end being projected from a casing; a first gear 42 disposed outside the casing 3 to be spline-coupled to the projecting part of the output shaft 5 and rotated in a body with the output shaft 5; and a second gear 44 rotatably supported on the casing 3 through a support shaft 43 to mesh with the first gear 42.
