As can be seen from said figures, with advantage, said traction elastic means 26 are in the form of one or more traction springs, in particular operating between said transversally extended part 122 and said fixing plate 126 of said fixed support means 12.

Advantageously, as can be seen from said figures, the respective traction spring 26 extends and is engaged to a corresponding radial projection 261 of said transversely extended part 122, and to a corresponding portion 262 of said fixing plate 126, i.e., of the respective first and/or second struts 126x', 126x" of the same base 126.

As can be seen from said figures, advantageously, said radial protrusion 261 of said transversally extended part 122 is arranged between said seat for said transferring gears of the movement of said driving steering wheel 11 and the corresponding outward channel of said electrical and/or data transmission cables 22 for connecting said means 19 that aid the pilot of said vehicle, or watercraft to a corresponding operative or working unit. In particular as illustrated, four radial projections 261 and four of said coupling portions 262 on said fixing base 126 are provided, for corresponding four traction springs 26, which as illustrated are angularly spaced apart from each other by 90°.

Advantageously, as can be seen from said figures, said means 16 for the transmission of motion, or rotation, of said driving steering wheel 11 towards, or to, means for directing said vehicle, or watercraft comprise a cardan member 160 having a first fixed part 161, to rotate with said end gear 202, of said means 20 for transferring the movement, or rotation, and a second articulated part 162, in a cardan like manner and supported by said first part 161.

In particular, as can be seen from particularly from the Figures 7A and 7B, said first part 161 and said second part 162 of the cardan joint are articulated to each other through a corresponding pin 163 fixed to said first part 161 and held in position by a corresponding spur 164, on which a block 169 rotates, from which a corresponding transversal shaft 165 extends, which is freely rotatable, by means of corresponding bushings 166, 166, into corresponding holes of said second part 162 of the cardan joint. As illustrated, said second part of the cardan joint comprises a first and a second portions 162, 162, which are joined together by corresponding screws 167, 167 and corresponding tightening nuts 168, 168.

Furthermore, as can be seen in particular from Figures 7A and 7B, a dust protection element 201'c for said bearing 201c and a Seeger ring 201"c for the retention, in particular longitudinal, of said bearing 201c are provided on said axially extended part 121.

In practice, as is evident, the above-illustrated technical features allow, individually or in a respective combination, to achieve one or more of the following advantageous results:

- a simple and robust structure can be obtained for the present support member;

- it is possible to adjust the position of the driving steering wheel, in particular by inclining it appropriately in relation to the pilot of the vehicle or watercraft. The present invention is susceptible of evident industrial application. The person skilled in the art can also devise a number of modifications and/or variations to be made to the same invention, while still remaining within the scope of the inventive concept, as widely explained. Furthermore, the person skilled in the art will be able to devise further preferred implementations of the invention, which comprise one or more of the characteristics illustrated herein above of the preferred implementation set forth above. Furthermore, it must also be understood that all the details of the invention can be replaced by technically equivalent elements.
