Abstract:
1. A slide rail device for a vehicle comprising: a lower rail which extends in a forward and rearward direction, wherein the lower rail is immovable relative to a floor of said vehicle; an upper rail which supports a seat and is supported on said lower rail to be slidably movable in the forward and rearward direction relative to said lower rail; a lock mechanism provided between said upper rail and said lower rail, wherein said lock mechanism restricts and releases the restriction of a sliding movement of said upper rail; a lock-operation lever which is inserted into an internal space of said upper rail, wherein the front side and the underside of said lock-operation lever is open, and lower edge portions of said lock-operation lever is provided with a lock-engaging portion; a rotational supporter which supports the lock-operation lever, so that when said lock-operation lever is positioned at a predetermined position in said internal space, said lock-operation lever is upwardly and downwardly rotatable between a locked position and an unlocked position with respect to said upper rail, wherein said lock mechanism is allowed to restrict said sliding movement of said upper rail at said locked position, and wherein, at said unlocked position, a front portion of said lock-operation lever is moved upward from said locked position whereby said lock mechanism releases the restriction of said sliding movement of said upper rail; a handle, wherein a rear-end portion of said handle is inserted into said internal space of said lock-operation lever, and wherein a front end portion of said handle projects forward from a front opening of said lock-operation lever; a biasing spring which is provided with an engaging portion which engages with said lock-engaging portion from below so that said engaging portion is allowed to restrict a movement thereof relative to said lock-engaging portion in the forward and rearward direction, wherein said biasing spring supports said rear-end portion of said handle in said internal space of said lock-operation lever while restricting the movement of said handle relative to said lock-operation lever in the forward and rearward direction; and a spring support portion, provided on said upper rail, which is positioned immediately below said biasing spring and prevents said biasing spring from falling downward from an underside opening of said lock-operation lever when said rotational supporter supports said lock-operation lever.
