PROBLEM TO BE SOLVED: To provide a linear motion bearing capable of stably supplying a lubricant for a long period and effectively inhibiting the generation of dust. SOLUTION: This linear motion bearing comprises a guide shaft 1, a plurality of rolling elements 2, a moving member 3 supported through the rolling elements 2 linearly movably along the guide shaft 1, and having a passage hole 3c through which the rolling elements 2 pass, and a cylindrical member 21 inserted into the passage hole 3c. The cylindrical member 21 is composed of a porous body vacuum-impregnated with the lubricant. COPYRIGHT: (C)2005,JPO&NCIPI |
