The present invention relates to an electric steering apparatus for a vehicle. The electric steering apparatus for the vehicle of the present invention comprises: a housing; a worm shaft installed at the interior of the housing; a worm wheel installed at the interior of the housing and engaged with the worm shaft; a bearing coupled to one end part of the worm shaft to rotationally support the worm shaft; and an anti-rattle member mounted on the bearing. The anti-rattle member includes: a first body unit surrounding the outer peripheral surface of the bearing; a second body unit provided integrally on the outside of the first body unit and in contact with the inside surface of the housing; and an elastic providing unit which provides an elastic force to the first body unit through a gap formed by cutting between the first body unit and the second body unit. Provided is the electric steering apparatus for the vehicle which can simultaneously satisfy a function to prevent a rattle noise caused by an inter-tooth gap between the worm shaft and the worm wheel which transmits a steering manipulating force and an anti-vibration function of a sliding damper.
