In a vehicle set slide device, a lower rail has a base portion extending in face-to-face relation with a vehicle floor, two first inside portions extending in close contact upward from a center part of the base portion, and lower hook portions extending outward from upper ends of both of the first inside portions each to take an inverted U-letter shape. An upper rail has vertical wall portions extending downward from both ends of a horizontal wall portion. Further, the upper rail is provided therein with a hook member which has joining portions joined with both of the vertical wall portions and extending downward and upper hook portions extending inward from lower ends of the joining portions each to take a U-letter shape. When a separation load against the lower rail is exerted on the upper rail, the lower hook portions and the upper hook portions are brought into engagements.
