<P>PROBLEM TO BE SOLVED: To provide a conveyer chain configured to prevent a leakage of lubricating oil to the outside, which is likely to occur, between an annular sealing member and a roller while avoiding wear and damages on the annular sealing member, and configured to reduce contact resistance between a thrust bearing annular member and rolling bearings, and to facilitate assembling of the annular sealing member to the thrust bearing annular member. <P>SOLUTION: The conveyer chain 100 includes: a plurality of rolling bearings 160 loosely inserted between an outer circumferential face 120a of a bush 120 and an inner peripheral face 130a of a roller 130; a pair of right and left thrust bearing annular members 170 press-fitted onto the outer circumferential face 120a of the bush 120 and disposed between an inner side face 110a of an inner link plate 1110 and an end face 160a of the rolling bearings 160; and an annular sealing member 150 for sealing lubricating oil within a region R where the rolling bearings 160 are loosely inserted, is disposed in a slidably contact state without deforming with respect to the inner peripheral face 130a of the roller 130 between the inner peripheral face 130a of the roller 130 and the outer circumferential face 170a of the thrust bearing member 170. <P>COPYRIGHT: (C)2012,JPO&INPIT |
