Claims

[Claims for Utility Model Registration] A seat frame equipped with a link member that is supported on a slide rail via a link member of a lifter mechanism and that moves up and down with respect to the slide rail when the link member rotates. The link member is shaped to eliminate at least one of the clearance between the slide rail and the link member during rotation, or the clearance between the lower surface of the seat frame and the link member during rotation. seat frame.
