PROBLEM TO BE SOLVED: To provide a double-row thrust needle-like roller bearing, coping with high-speed rotation with low torque and having a long life. SOLUTION: This double-row thrust needle-like roller bearing includes: a rolling element composed of an outer roller 303 disposed outside in the radial direction of the bearing between a pair of opposite raceway surfaces and an inner roller 302 disposed inside in the radial direction of the bearing; and a retainer 301 retaining the outer roller 303 and the inner roller 302. The retainer 301 is guided by the rolling elements 302 and 303 not to come into contact with the paired raceway surfaces. COPYRIGHT: (C)2006,JPO&NCIPI
