A belt-type continuously variable transmission that prevents escape of noise generated by a resin block belt to the outside. The resin block belt is wound around a primary sheave and a secondary sheave. A transmission case defines a belt chamber accommodating the primary sheave, secondary sheave, and resin block belt. The transmission case includes an exhaust passage, intake passages, and a sound absorbing member. The sound absorbing member is attached to an inner wall of the exhaust passage in a position to collide with sound waves traveling through the exhaust passage. The sound absorbing member has a sound absorbing surface crossing an extending direction of the exhaust passage.
