PROBLEM TO BE SOLVED: To facilitate mounting of a rod-shaped spring for energizing a latch lever of a lock mechanism. SOLUTION: The two ends of the rod-shaped spring 11 are abutted to the inside of the part where an upper rail 2 is formed bent, while the central part 11c is engaged with the latch lever 8, which is provided with an engaging hole 17a, and there a spring hitching part 17 is formed protruding from the inner surface of the hole 17a to the direction of compressing the rod-shaped spring 11, and in the central part 11c of the spring 11, a hitching part 11g is formed for generating hitching at the spring hitching part 17 upon intruding into the hole 17a while it is bent toward the latch lever approximately in a U-letter shape.
