To provide a V-belt continuously variable transmission system for a straddle type vehicle which is capable of avoiding an increase in size around a driven pulley of the V-belt continuously variable transmission system and of improving the freedom of design including layout of component parts, in relation to a mounting structure of a rotational speed sensor. A V-belt continuously variable transmission system for a straddle type vehicle has a belt transmission chamber (68) formed in an internal area between a transmission case (23) and a transmission case cover (80) for covering the transmission case (23) from the outside in the vehicle width direction. A drive pulley (61) pivotally supported on a drive shaft (40) extending in the vehicle width direction, a driven pulley (65) pivotally supported on a driven shaft (74) which is arranged in parallel with the drive shaft (40), and a V-belt (64) wrapped around the drive pulley (61) and the driven pulley (65), are accommodated in the belt transmission chamber (68). A rotational speed sensor (120) for detecting a rotational speed of the driven pulley (65) is mounted on the transmission case cover (80). The rotational speed sensor (120) is arranged on the inside of the V-belt (64) which is rotated in an annular shape, when viewed in the axial direction of the drive shaft (40).
