Abstract:
A seat slide unit comprising:left and right upper rails adapted for connection to a bottom of a seat so as to extend in a fore-and-aft direction relative to the seat;left and right lower rails for guiding said left and right upper rails slidably back and forth relative to the seat;a left lock mechanism being capable of locking and unlocking said left upper rail with respect to said left lower rail;a right lock mechanism being capable of locking and unlocking said right upper rail with respect to said right lower rail;an operation bar being rotatably supported at left and right end parts in front parts of said left and right upper rails and extending in an intermediate portion from side to side for causing one of said left and right lock mechanisms to lock and unlock in response to a rotation direction of the intermediate portion; anda coupling member being coupled at left and right end parts to said left and right lock mechanisms and shaped so as to absorb a warp between the left and right end parts for causing the other to lock and unlock in conjunction with one of said left and right lock mechanisms,wherein coupling positions of the left and right end parts of said coupling member and said left and right lock mechanisms differ at least back and forth or up and down.
