PROBLEM TO BE SOLVED: To provide a linear guide device in which an impression is hardly generated in a rolling groove even if a large load is applied to a slider.SOLUTION: At least one groove out of a groove of a guide rail 4 and a groove of a slider 10 is formed by combining two curved faces whose cross sections are circular, and formed into a substantially-V shape in its cross section, the two curved faces are formed of one curved face with which a ball 7 contacts in a use state, and the other curved face with which the ball 7 does contact in the use state, and a depth from an end of one curved face in the circumferential direction up to a groove bottom is set deeper than a depth from an end of the other curved face in the circumferential direction up to the groove bottom. |
