摘要：A linear motion guide unit is disclosed in which a tubular composition to providea return passage is high in mechanical stiffness and also makes certain of sustainableapplication of lubricant to rolling elements rolling through the return passage, therebyensuring proper lubrication under maintenance-free operation. The tubular composition

to make the return passage is composed of a tubular skeleton to guide the rollers, and aporous compact impregnated with lubricant. The tubular skeleton is made up of forwardand aft ends, a lengthwise column and a flexible spine, which extend between the ends.The flexible spine includes lengthwise opposite relief portions and a flexible middlesection, which fit into the porous compact with separating from the porous compact tomake a clearance between them. The flexible spine deflects as the rollers roll throughthe return passage, permitting the rollers coming into touch with the porous compact tolubricate the rollers.
