Embodiments of the present invention relate to a reducer for a vehicle steering device. The embodiments of the present invention provide a reducer for a vehicle steering device, comprising: a worm shaft where a gear unit geared and coupled to a worm wheel is formed on an outer circumferential surface; bearings respectively coupled to both side end parts of the worm shaft; and a damper axially supporting at least one of the bearings to be coupled and restraining length which is elastically deformed in an axial direction during assembly. Provided is the reducer for a vehicle steering device, which can increase steering sensation of a driver by reducing jamming and rotational resistance of the worm shaft and the bearing.
