Abstract

The invention relates to a gear reducer () for an assisted-steering module, including a casing (), a worm () which meshes with a worm wheel (), and a spring () for taking up gear play, which presses said worm () radially against the worm wheel (), the wall of the casing () being bored, away from of the axis (XX') of the worm, with an opening () sealed by a plug (), the spring () for taking up gear play including at least one retaining lug () which projects radially to the axis (XX′) of the worm (), and the hub () of the plug () having a guiding wall () that is substantially transverse to the axis (XX′) of the worm (), which is designed to be placed axially opposite said at least one retaining lug (), in order to prevent the axial movement of the spring () beyond a predetermined functional travel.
