ッドレストの角度調節装置。A first core metal is fixed to a headrest stay that supports the headrest, a second core metal is rotatably attached to the headrest stay coaxially with the first core metal, and is appropriately connected to the headrest frame, These coil springs, which have a somewhat smaller diameter than those of the core metals, are expanded in diameter, and one end of the coil springs is hooked onto the second core, and is extrapolated onto both cores.
The lock release claw that engages with the hook portion at the other end of the coil is biased in the engagement direction and is rotatably attached to the second core metal, and the coil spring and the A headrest angle adjusting device characterized in that rotation of the headrest in one direction is locked by frictional force generated between the core metal and the lock is released by engagement between the lock release claw and the hook portion at the other end. .
