<p><P>PROBLEM TO BE SOLVED: To implement a structure which can prevent dynamic torque based on the interference of both radial from increasing and thrust retainers 11a and 13c without using another member necessary only for preventing the interference. <P>SOLUTION: An inside diameter R<SB>13</SB>of the thrust retainer 13c is made smaller than an outside diameter D<SB>11</SB>of the radial retainer 11a. The portion near the inside diameter in an axial one side surface of the thrust retainer 13c is slid or closely faced to the portion near the axial one side surface inside diameter of a flange wheel 22. By employing this structure, the attitude of the thrust retainer 13c is restricted by a ring guide so that the thrust retainer 13c is not made tilted even when the radial retainer 11a is struck to the thrust retainer 13c. The friction between a pocket 25 of the thrust retainer 13c and the rolling surface of each thrust roller 12c is prevented from increasing so as to solve the problems. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
