PURPOSE:To aim at shortening the axial length of a device, by installing a clutch in a speed change pulley carrying a transmission control cam, while setting up this clutch at the side of an adjustable sheave of the speed change pulley and also setting up a clutch control cam superposingly on the transmission control cam. CONSTITUTION:A speed change pulley 11 at the driven side in a belt type nonstep transmission device 7 is provided with a fixed sheave 21 being supported free of rotation only by a main shaft 6a via a bearing 20 and an adjustable sheave 23 being rotatably and slidably sypported via a bearing 22. A clutch 25 is set up on the backside of the adjustable sheave 23, and this cluth 25 is connectably formed by traction control of a wire 36 by means of a nonstep transmission control lever via a transmission control sliding cam 35 and a fixed cam 32. In addition, with the traction control of a wire 42 by means of a main clutch control lever, the clutch 25 is formed so as to make it connectable via a clutch control sliding cam 41 and a fixed cam 37, while these cams 37 and 41 are set up superposingly on the transmission control sliding cam 35. |
