Zusammenfassung:	A power steering device includes a worm shaft configured to rotate as an electric motor is driven; a worm wheel meshed with the worm shaft, the worm wheel being configured to transmit a rotational force of the electric motor to a rack shaft configured to turn wheels; a bearing that rotatably supports a tip side of the worm shaft; a gear case that houses the worm shaft; a biasing member configured to bias the worm shaft toward the worm wheel via the bearing; and a holder including a housing hole configured to house the bearing movably in a biasing direction of the biasing member. The holder includes a plurality of bulging parts formed to bulge radially outwardly, the bulging parts being configured to come into contact with an inner peripheral surface of the gear case.
