1. A continuously variable transmission comprising:
a CVT mechanism including a driving pulley, a driven pulley, an annular belt wound around the driving pulley and the driven pulley, and a centrifugal fan blade disposed at the driving pulley; and
a CVT case that defines an internal space accommodating the CVT mechanism, wherein
an inner surface of the CVT case includes:
a peripheral surface portion that covers the CVT mechanism from an outer side in a radial direction orthogonal to an axial direction of the driving pulley; and
a guide surface portion that projects toward an inner side in the radial direction from the peripheral surface portion,
the driving pulley includes:
a fixed sheave at which the centrifugal fan blade is disposed; and
a movable sheave opposed to the fixed sheave from a first side in the axial direction, and
the guide surface portion is arranged at a second side in the axial direction beyond a radially outer end of the movable sheave when the movable sheave is located closest to the fixed sheave.
