<p>The problem of the present invention is to provide a slide rail device for a vehicle such that an upper rail can be prevented from rattling vertically and horizontally relative to a lower rail and production costs can be reduced. The solution is a slide rail device provided with a lower rail (15) the inner surface of which comprises a roller support surface (17a) and a pair of left and right ceiling surfaces, an upper rail (26) capable of moving longitudinally relative to the lower rail, a plurality of rollers (56) moving together with the upper rail longitudinally relative to the lower rail and connected to the roller support surface so as to be capable of rotating about a horizontal rotational axis, and a rattle-eliminating member (58) that moves together with the upper rail longitudinally relative to the lower rail and comes in contact with the ceiling surfaces, the regions of the left and right ceiling surfaces where the rattle-eliminating member comes in contact therewith constituting inclined surfaces (19a) that are bilaterally symmetrical with each other and are inclined relative to the horizontal direction.</p> |
