ンバーサポート装置。[Claims for Utility Model Registration] The drive shaft is pivotally supported by the frame, and the latch plate is rotated in conjunction with an operating lever attached to the drive shaft, and the latch plate is engaged and pressed against the frame. In a lumbar support device, the cam rotates together with the ratchet, and the displacement of the cam is changed to adjust the biasing force of the biasing means acting on the lumbar plate. A lumbar support device formed separately from a shaft, and characterized in that a support shaft and a drive shaft are independently rotatably supported on a frame.
