サポート装置。[Claim for Utility Model Registration] The latch rotates together with the cam due to the engagement and pressure of the pawl of the latch plate that is linked to the operating lever, and the displacement of the cam is changed to cause the biasing means to act on the lumbar plate. In a lumbar support device that adjusts the biasing force, a friction brake member is pressed against the circumferential surface of the cam,
A lumbar support device characterized by regulating the rotation of a cam.
