At least one side wall (12d, 22d, 315) at least of the inner sleeve (10) has an additional wall plate (11, 21). Another alternative proposes that at least one side wall (12d, 22d, 315) at least of the inner sleeve (10) consists of a wall plate (11, 21) to which the two adjacent side walls (12a, c, 22a, c, 312, 314) are fastened. An arrangement of such a support jack on the lower side of a vehicle is also described.
