PCT No. PCT/SE90/00706 Sec. 371 Date Apr. 30, 1992 Sec. 102(e) Date Apr. 30, 1992 PCT Filed Oct. 31, 1990 PCT Pub. No. WO91/06461 PCT Pub. Date May 16, 1991.An adjustable steering wheel, preferably for trucks, includes a steering column (4) on an upper supporting arm (3), which is pivoted in a lower supporting arm (2), which in turn is pivotally mounted to a windshield beam, for example, in the cab. A locking device in the form of a first and a second friction plate package (19, 11) with an intermediate conical spring washer package (30) locks the supporting arms relative to each other and relative to the cab. By means of a pair of levers (32, 33), a control cable (36) and a foot pedal, the spring package can be compressed to remove the locking effect of the plate packages.
