PROBLEM TO BE SOLVED: To provide a linear motion guide device which can maintain lubrication performance for a long period of time.SOLUTION: A slider 2 of a linear motion guide device is constituted of a slider main body 2A and an end cap 2B, and attached with a lubrication member 20 for holding a lubricant. A lubricant supply part 22 which supplies the lubricant of the lubrication member 20 to a rolling body 3 which moves in a direction conversion path 15 is arranged at the lubrication member 20 so as to protrude from the lubrication member 20 toward the end cap 2B. A protruding tip of the lubricant supply part 22 extends up to an opening of a hole 18 formed at the end cap 2B at the direction conversion path 15 side, and a protruding tip face 22a is exposed into the direction conversion path 15. Since the rolling body 3 which moves in the difference conversion path 15 contacts with the protruding tip face 22a when the protruding tip face 22a passes through an exposed portion, the lubricant of the lubrication member 20 is supplied to a surface of the rolling body 3.The supplied lubricant is adsorbed into a hole 3a of the rolling body 3 which is formed of a porous material. |
