Patent attributes
A seat slide structure includes a cushion frame, a slide rail including lower and upper rails, a movement mechanism, and a lock mechanism. The movement mechanism slides the cushion frame along a length direction of the slide rail. The lock mechanism includes a lock body engaging with the slide rail, and places or lifts a restriction on movement of the slide rail. The movement mechanism includes a lead screw, a gear part, and a shake absorber. The lead screw is provided in parallel with the slide rail, and is supported by the upper rail. The gear part transmits power from a power source to the lead screw to slide the lead screw and the upper rail along the lower rail. The shake absorber allows the cushion frame and the lead screw to move relative to one another in a moving direction of the upper rail along the lower rail.
