摘要

The present invention relates to a jack for a spare wheel which is intended for lifting a spare wheel to be mounted at the level of the lower face of a vehicle shell and which comprises the following members: a vertical driving shaft (18) which is perpendicular to the vehicle shell; a pulley or take-up cylinder (30) which driven by the driving shaft through a reduction gear (22) and on which a lifting cable (32) can be wound up; and an abutment (40) which can be mounted on the free and vertical end area (32) of the lifting cable (32) and which is used for carrying the spare wheel. In order to increase the operation reliability, this jack is designed so that the pulley or take-up cylinder (30) is located on a horizontal winding shaft (20) and is connected thereto so as to be blocked upon rotation. The reduction gear (22) is made in the form of a worm gear in which the worm screw (24) is located on the driving shaft (18) while the wheel (26) thereof is located on the winding shaft (20).
