Patent ID: 7803074

Claim:
A belt type continuous variable transmission comprising: a primary sheave that outputs torque, a secondary sheave that receives torque from the primary sheave, and a belt entrained between the primary sheave and the secondary sheave in an endless manner to transmit torque to the secondary sheave from the primary sheave, wherein the primary sheave comprises: a first sheave body, a second sheave body provided to be relatively slidable in a direction toward and away from the first sheave body and forming between the second sheave body and the first sheave body a belt groove, about which the belt is entrained, a plurality of push bodies that rotate together with the second sheave body and move radially of the second sheave body according to centrifugal forces generated at the time of rotation of the second sheave body, such movements causing the second sheave body to slide to change a width of the belt groove, and a plurality of stoppers that restrict movements of the push bodies by contacting with outer surfaces of the push bodies when the second sheave body reaches a position of minimum transmission gear ratio, in which the belt groove is made smallest in width, the stoppers being shaped to accelerate partial wear of the outer surfaces of the push bodies, wherein each of the plurality of push bodies includes a roller weight and at least outer peripheries thereof are lower in hardness than the plurality of stoppers.
