<P>PROBLEM TO BE SOLVED: To provide a cage of a thrust roller bearing capable of improvement for lubrication failure due to slipping, by supplying grease to a rolling surface during rotation without increasing rotation torque at the initial stage of the rotation. <P>SOLUTION: The cage 1 of a thrust roller bearing is obtained by connecting an inner-diameter side ring part 3 and an outer-diameter side ring part 4 by a plurality of columns 5, and forming a plurality of pockets 6 for holding rollers 2 therebetween. An annular lubricant reservoir 7 is formed in the inner-diameter side of a cylindrical partition wall 3a of the inner-diameter-side ring part 3, which faces the pockets 6, and lubricant supply holes 8 for communicating the lubricant reservoir 7 with the pockets 6 are formed in the partition wall 3a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
