Abstract:
1. A power slide device for a vehicle seat, comprising: a lower rail which is immovable with respect to a vehicle floor and extends in a forward/rearward direction; an upper rail which supports a seat, said upper rail being slidable relative to said lower rail in a lengthwise direction of said lower rail; a front support member fixed to said lower rail; a screw rod which extends in said forward/rearward direction, wherein a front portion of said screw rod is supported by said front support member; a rear support member provided with a rear orthogonal plate portion and a fixed plate portion, wherein said rear orthogonal plate portion lies in a plane orthogonal to a straight line extending in said lengthwise direction of said lower rail, wherein a rear through hole, into which a rear portion of said screw rod is inserted, is formed in said rear orthogonal plate portion, and wherein said fixed plate portion extends rearward from a lower end of said rear orthogonal plate portion and is fixed to a base surface of said lower rail; a movement limiter which limits movement of said screw rod relative to said rear support member; a worm wheel provided with a female screw hole, in which said screw rod is screw-engaged so as to extend and pass through said worm wheel, wherein said worm wheel moves with said upper rail in said forward/rearward direction relative to said lower rail by rotating by power of a driver; and a collision load receiving portion which limits forward tilting of said rear orthogonal plate portion by contacting said base surface of said lower rail when a force is exerted on said screw rod forwardly from said worm wheel, wherein said collision load receiving portion is positioned in front of said rear orthogonal plate portion in said forward/rearward direction and is spaced downward from said screw rod and integrated with said rear support member that is mounted to said screw rod.
