PROBLEM TO BE SOLVED: To provide a structure improving the radiation performance of heat generated in meshing between gears while retaining lubricity, rust prevention, and abrasion resistance as a non-lubrication method in a dry type continuously variable transmission. SOLUTION: A small-diameter gear portion 93b of a second intermediate gear 93 in a gear train 9 and small gear portions 14a and 14b of a connecting shaft 14 are constituted of a metal material so as to improve the heat radiation performance, while respective outer circumferential gear portions 102c and 152c of respective removable annular bodies 102 and 152 of first and second feed mechanisms 10 and 15 are constituted of a resin material so as to retain the lubricity, the rust prevention, and the abrasion resistance.
