To suppress flexure of an input shaft of a four-joint link type continuously variable transmission. The four-joint link type variable transmission is equipped with a hollow input shaft, an output shaft, an eccentric mechanism, a swing link, a one-way rotation preventing mechanism, a connecting rod, and a pinion shaft inserted into the input shaft. The connecting rod has, at one end portion, a large-diameter annular portion externally fitted to the eccentric mechanism so as to be capable of rotating freely, and the other end coupled to a swing end portion of the swing link. To the pinion shaft, a roller bearing for pinion supporting the input shaft is provided.
