Abstract: A pulley support structure for a belt-drive continuously variable transmission and a belt-drive continuously variable transmission are provided that are able to control the occurrence of Mindlin slip itself, and in cases where Mindlin slip has occurred, are able to effectively reduce the effects thereof. In this pulley support structure for a belt-drive continuously variable transmission, 2500 MPs or less is the maximum contact pressure during use between the raceway surfaces of the inner wheel and outer wheel and the rolling elements in the various roller bearings for rotatably supporting the pulleys for the continuously variable transmission. The rolling element surface hardness is HRc 60 or greater, and is at least 1 HRc harder than that of the raceway surfaces. The surface of the rolling element is nitrided or carbonitrided, and the nitrogen concentration in the surface is 0.2% by mass or greater and 2.0% by mass or less.
