<p>PROBLEM TO BE SOLVED: To deal with high speed and high load by connecting either of an inner cylinder arranged and fixed spacedly in the circumferential direction on the outer circumferential part of a coupling or an outer cylinder positioned on the outer circumferential part of the inner cylinder leaving a fine gap to the output shaft of a motor, and connecting the other to a propeller shaft. SOLUTION: The circumferential part of the inner cylinder of a coupling 21 is fitted to the output shaft 20 of a motor 19 so as to rotate in one body with the output shaft 20, and the outer cylinder is arranged so as to surround the outer circumferential side of supporting plates radially fitted to the outer circumferential part of the inner cylinder. A joint 22 is fitted to a propeller shaft 18, and hence it is rotated in one body with the outer cylinder. Because this running device provided with the coupling 21 supports the front part and the rear part of a vehicle body, and bears load for running with all running wheels, a slip phenomenon is hardly generated, and the motor 19 is immediately controlled by action of a controller so as to normally rotate even at becoming high speed and high load. Hereby reliability can be improved.</p> |
