<p>A slide rail device for a vehicle, which enables a lock spring to be supported without rattling in the front-to-back direction (longitudinal direction) with respect to an upper rail, is provided. This slide rail device for a vehicle is characterized in that: first and second engagement parts (an engagement part for latching grooves (35) and locks (51a), and an engagement part for latching grooves (35) and locks (51b)), which exert a force that constantly and simultaneously acts between the upper rail (30) and the lock spring (50) in the longitudinal direction, are disposed on the upper rail (30) and the lock spring (50); and a force that acts between the upper rail (30) and the lock spring (50) in the longitudinal direction in the first engagement part (the engagement part for the latching grooves (35) and the locks (51a)), and a force that acts between the upper rail (30) and the lock spring (50) in the second engagement part (the engagement part for the latching grooves (35) and the locks (51b)) in the longitudinal direction are made to differ from each other so as to eliminate play in the longitudinal direction with respect to the upper rail (30) of the lock spring (50).</p> |
