PROBLEM TO BE SOLVED: To provide a continuously variable transmission mechanism capable of reducing the outer diameter of each eccentric disc to reduce the size of the whole mechanism by forming the eccentric disc with through-holes communicating each other where a pair of crank pins are arranged close to each other.SOLUTION: A continuously variable transmission mechanism includes transmission ratio varying mechanisms using an actuator for changing a transmission ratio when rotating power input to an input shaft is transmitted as rotating power via eccentric discs 104 and connection members to an output member of a one-way clutch, and for setting the transmission ratio to be infinite with an eccentricity made zero-settable. Through-holes 104a, 104b include a first through-hole 104a through which first crank pins 106c-106h are inserted and a second through-hole 104b through which second crank pins 107c-107h are inserted. Partial regions of inner peripheral faces of the first through-hole 104a and the second through-hole 104b are communicated with each other, and the communicated regions are provided where the first through-hole 104a and the second through-hole 104b are closest to each other, at the least.SELECTED DRAWING: Figure 11 |
