PROBLEM TO BE SOLVED: To improve the durability of a dry belt type continuously variable transmission including rolling bearings 3, 3 by improving the durability of the rolling bearings 3, 3 incorporated in a rotation supporting part. SOLUTION: In the rolling bearings 3, 3, grease is filled which uses a lithium soap as a thickening agent and ester oil as base oil, the base oil having a viscosity of 20-80 mm<SP>2</SP>/s at 40°C and a miscibility of 200-300. The temperature rise of a rolling contact part is suppressed while forming a good oil film thereon, to prevent the metal contact of the rolling contact part. COPYRIGHT: (C)2005,JPO&NCIPI
