トスライド装置。[Scope of Claim for Utility Model Registration] A pair of rail units consisting of a rail on the vehicle body side that is fixed at the installation site, and a rail on the seat side that fits into the rail on the vehicle body side so as to be movable in the longitudinal direction and supports the seat. Each rail unit is provided with a locking mechanism that immobilizes the rail on the seat side relative to the rail on the vehicle body side, and both locking mechanisms are pulled in order to synchronize and release the restraint. In a seat slide device that is linked via a wire, each of the pair of lock mechanisms is rotatable about an engaging portion provided on a rail on the vehicle body side and a pivot axis parallel to the rail on the seat side. a latch member provided on the latch member that engages and disengages from the engaging portion, the latch member of the one lock mechanism having an upper arm portion extending above the pivot of the latch member, and the latch member of the one lock mechanism that The member is formed with an under arm portion extending below the pivot axis of the latch member, and the pull wire extending from the upper arm portion toward the under arm portion is connected above a line connecting the upper arm portion and the under arm portion. The avoidance member is connected to one end of the avoidance member that is bent to widen the space between the latch member and the installation part, while the other end of the avoidance member is connected to the under arm portion so as to be pivotable about an axis parallel to the pivot axis of the latch member. A seat slide device characterized by supporting the seat.
