PROBLEM TO BE SOLVED: To provide a linear motion guide unit in which an inner seal is positioned and attached to a slider in a hermetic condition, intrusion of foreign matter to a circulation passage can be prevented, and the slider can be relativity slid smoothly.SOLUTION: An inner seal 7 is disposed in close contact with a lower surface 29 of a slider. The inner surface seal 7 is constituted by a body part 15 having an elastic member 20 and a core metal member, a lip part 16 of the elastic member 20 extended from one side surface to the whole length and brought into slide contact with an upper surface 22 of a track rail 1, and a hook part 17 extended orthogonally from both ends and fitted in a recessed groove 32 of an end cap 4 so as to lock the inner surface seal 7. The other side surface 59 of the body part 15 is formed in a prop surface 56 that extends to and abuts on an inner wall surface 55 of the end cap 4 so that the hook part 17 is pushed to one side of the recessed groove 32 to be positioned and fixed. |
