<p><P>PROBLEM TO BE SOLVED: To reduce axial thrust applied to a movable pulley half body at the input of excessive torque while avoiding increases in the number of components and assembling man-hours to attain miniaturization in a belt-type continuously variable transmission including a torque cam mechanism on the driven pulley side. <P>SOLUTION: The torque cam mechanism 23A includes a torque pin 42 movably supported in an elongate hole 41 provided on one side of a fixed pulley half body 20 and a movable pulley half body 21 and extended in the axial direction of the pulley half bodies 20, 21; a spiral guide recess 43 provided on the other side of the fixed pulley half body 20 and movable pulley half body 21 to fit the torque pin 42; and a torque pin urging means 44A urging the torque pin 42 to the opposite side to the moving direction of the movable pulley half body 21 to reduce a reduction ratio. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
