PROBLEM TO BE SOLVED: To provide a seat slide device for a vehicle capable of suppressing deformation of an upper rail to assure higher reliability.SOLUTION: An upper rail 6 includes a reinforcement bracket 50 capable of suppressing the deformation, such that a space between both of side wall parts 15 of the upper rail 6 becomes narrower, of the upper rail 6 by lying between both of the side wall parts 15. The reinforcement bracket 50 includes a stopper part 60 capable of limiting a relative movement range of the upper rail 6 by contacting with a protrusion part 57 provided on a lower rail 5 on the basis of the relative movement of the upper rail 6. |
