The present invention provides a lumbar support installed on a vehicle seat to support a lumbar portion of a user. According to the present invention, the lumbar support for a vehicle seat comprises: a support panel to support a back portion of a user; a first wire and a second wire to support a bottom portion of the support panel; a towing wheel to restrict each end of the first and second wires to wind the first and second wires on a circumferential surface thereof; and a driving unit to rotate and drive the towing wheel. The towing wheel includes: a first wire guide groove extended and formed along the circumferential surface to wind the fire wire thereon; and a second wire guide groove extended and formed along the circumferential surface at a thickness direction position different from the first wire guide groove to wind the second wire thereon. The lumbar support for a vehicle seat can improve sitting comfort by properly changing supporting power for a lumbar portion.
