PROBLEM TO BE SOLVED: To achieve securing lock intensity of a slide rail and narrowing a lock pitch of slide lock.SOLUTION: A slide rail 10 comprises: four lock pieces 13P1-13P4 which are attached to an upper rail 12 and locking slide between both rails 11, 12 by entering plural lock grooves 11B1 formed on a lower rail 11 by energization. The respective lock grooves 11B1 comprises a constant groove width W in a slide direction, the lock grooves are arranged at equal interval in the slide direction with a gap D which is three times of the groove width W, the left and right lock grooves being a pair. The four lock pieces 13P1-13P4 are arranged two by two on left and right sides, and arranged in the slide direction so that, the respective lock piece is positioned on a phase deviated by 1/4 of the pitch P in the same pitch P in which the respective lock groove 11B1 is arranged.SELECTED DRAWING: Figure 12 |
