PROBLEM TO BE SOLVED: To enhance lock intensity without size increase of a slide rail.SOLUTION: A slide rail 10 comprises: a lower rail 11 attached to a floor; an upper rail 12 assembled to the lower rail 11 in a slidable state; and lock springs 13A attached to the upper rail 12, entering by energization, lock grooves 11B1 formed on the lower rail 11, for locking slide between both rails 11, 12. Three lock springs 13A are provided and arranged in the slide direction and comprise a lock possible spring in which an arrangement state of the lock springs allows them to enter the lock grooves 11B1 regardless of a slide state of the upper rail 12, and a lock impossible spring in which the lock springs are in an arrangement state in which they get on a rack between the lock grooves 11B1. On the rack, restrain grooves 11B2 for restraining movement of the received lock impossible springs in the slide direction, are formed. |
