Claims (1)

[Claims for Utility Model Registration] (1) A seat portion of a seat having a backrest portion that can be tilted forward is fixed to a movable rail that is slidably provided along a fixed rail fixed to the vehicle body, and A plurality of engagement holes are formed in the side surface of the lock plate fixed to the side thereof in a row in the longitudinal direction of the fixed rail, and a memory portion consisting of a lower edge and a higher edge is formed on the upper edge thereof, and A lock pawl that can selectively engage and disengage one of the engagement holes is fixed to an operating shaft parallel to the movable rail that is pivotably supported on the movable rail side, and when the backrest of the seat is tilted forward. , a retaining member linked to the backrest portion is pivotally fitted to the operating shaft so as to engage with a portion of the lock pawl and rotate in a direction to disengage the lock pawl from the engagement hole; A first spring that biases the claw in the direction of engaging the engagement hole is provided between the movable rail and the operating shaft or the lock claw, and further, the tip of the spring is in contact with the side surface of the high edge of the memory part, A locking lever that prevents the retaining member from returning in a direction opposite to the direction in which the lock claw is released and is normally located above the memory portion has its tip protruding toward the side of the retaining member. A second locking member pivotably connected to the retaining member so as to be pivotable upward from the stop position, urging the locking lever toward the stop position and urging the retaining member in a direction opposite to the direction in which the lock claw is released. A spring is provided between the locking lever and the movable rail, and when the seat is in a position forward from a predetermined standard position, the locking lever is located on the high edge of the memory section, and in this state When the retaining member rotates in the locking claw release direction, the tip of the locking lever passes over the high edge, and
A seat slide device for an automobile, characterized in that the position and dimensional relationship between the high edge of the memory part, the retaining member, and the locking lever are determined so that they can abut against the side surface of the high edge. (2) The middle part of the second spring is wound around the operating shaft,
One extending end is locked to the movable rail, and the other extending end passes through and hangs down from the upper edge of the retaining member, and its end is locked in the recess of the locking lever. An automobile seat slide device according to claim (1) of the utility model registration, which comprises one coiled spring.
