摘要： In a continuous speed-shifting device in which a variable speed pulley mechanism and a planetary gear mechanism are combined with each other, respective cam mechanisms are provided on respective back sides of movable sheaves of variable speed pulleys of the variable speed pulley mechanism so as to move the sheaves toward and away from fixed sheaves of the variable speed pulleys, a linkage mechanism for linking both the cam mechanisms to each other is provided so that the diameters at which the belt is wound around both the pulleys are varied in a reverse direction to each other, the variable speed pulley mechanism is shifted in speed in such a manner that an output gear for supporting a pinion of the planetary gear mechanism is switched among a normal rotation state, a neutral state and a reverse rotation states with respect to a rotary shaft, the output gear is adjustable to the neutral state by a balance between the thrusts to the belt by both the pulleys, and the variable speed pulley mechanism serves as a circulating power channel at the forward state of the vehicle at which the use frequency is higher. Thus, the frequency with which large driving power is applied to the belt of the pulley mechanism is decreased so that the belt load is reduced, thereby readily obtaining the normal and reverse rotation states without a normal and reverse rotation mechanism.

摘要： A belt-type one-way clutch is arranged so that a case is assembled with a flat pulley so as to rotate around the central axis of the flat pulley, and that a flat belt is looped between a working surface of a rocking member supported for rocking motion by a shaft member held at both ends in shaft bores of the case and a working surface of the flat pulley, and that the rocking plate biased from a leaf spring presses one span of the flat belt to place an initial tension on the flat belt. Both the ends of the shaft member are held in the shaft bores of the case via respective bushes to suppress stress. Accordingly, larger torque can be transmitted despite use of aluminum alloy as material of the case.
