Abstract: In a seat sliding device, an upper rail slidably moveable relative a lower rail interlocks with the lower rail upon movement of the upper rail away from the lower rail. An upwardly inclined portion and a downwardly inclined portion can be provided on the upper rail and the lower rails, respectively. A spacer element is provided between the upwardly inclined portion of the upper rail and a corner of the lower rail. The inclined portions and the spacer elements interlock upon movement of the upper rail away from the lower rail. Due to sufficient area being provided between the interlocking portions, separation of the upper rail from the lower rail can be prevented.

Abstract: A spring coupler comprises a casing, a drive member rotatably mounted within the casing including a main portion and a core portion fixedly connected thereto by staking manner, a driven member rotatably mounted within the casing including a main portion and a core portion fixedly connected thereto by stacking manner and engageable with the core portion of the drive member upon rotation thereof, and a coil spring disposed between the drive member and the casing so as to be engaged frictionally with the casing in the free state thereof and including a first tang and a second tang.
