PROBLEM TO BE SOLVED: To provide a rectilinear guide device capable of preventing an underseal from coming off, allowing a part for preventing the coming off to be easily processed, and restraining manufacturing cost.SOLUTION: An underseal 50 of this rectilinear guide device includes elastically deformable protrusions 52 respectively in both end parts of itself, on faces directed in a self-thickness direction. An end cap 5 includes a coming-off preventive stepped part 62 engaged with the protrusions 52 of the underseal 50 in a direction opposed to a guide rail, and allowing moving in a longitudinal direction of the underseal 50, in an inside of an underseal groove 60. The stepped part 62 is formed of a border between a narrow width part 64 and a wide width part 66, by bringing a guide rail side into the narrow width part 64 narrowing a groove width of the underseal groove 60, and by bringing a side opposed to the guide rail into the wide width part 66 making the groove width wider than that of the narrow width part 64. |
