<p>A belt-type continuously variable transmission in which a sheave is not inclined even if it is heated. The transmission comprises: a fixed sheave integrally formed with a rotary shaft; a movable sheave fitted onto the rotary shaft in a manner to slide in an axial direction; a belt interposed between the movable sheave and the fixed shave to transmit power; and a bush interposed between the rotary shaft and the movable sheave to allow the movable sheave to slide on the rotary shaft. The bush is formed to have a smaller coefficient of thermal expansion at an axial end portion thereof in the vicinity of a contact face of the movable sheave to which the belt is contacted, in comparison with that at the other axial end portion.</p>
