PROBLEM TO BE SOLVED: To provide a continuously variable transmission capable of improving belt transmission efficiency by sufficiently supplying lubricant to surroundings of an inner pin and smoothly sliding the inner pin.SOLUTION: In a continuously variable transmission CVT where a chain belt 3 is bridged between opposite sheave surfaces 11, 21 of a primary pulley 1 and secondary pulley 2, the chain belt 3 is installed in a locker pin 32, and includes: a pair of inner pins 33, 33 whose pin end parts 33b are formed on the sheave surface 21 and that are engaged to a radial recess groove 23; and a coil spring 35 expanding to the pair of inner pins 33, 33 to impart energizing force. Then, between the locker pin 32 and the inner pin 33, there formed is an oil groove 37 where lubricant flows.SELECTED DRAWING: Figure 5 |
