Claims

[Scope of utility model registration request]

A front bell crank 13 for steering the front wheels 8 is pivoted to a front pivot 12 disposed at the front of the fuselage frame 1, and a rear bell crank 13 for steering the front wheels 8 is pivoted to a rear pivot 16 disposed at the rear of the fuselage frame 1. The rear bell crank 17 to be rotated is interposed between the pitman arm 21 and the rear bell crank 17, and a steering interlocking mechanism M consisting of a drag rod of 22 degrees is interposed between the pitman arm 21 and the rear bell crank 17.
A relay arm 20 is branched and connected in the middle of the steering interlocking mechanism,
The relay arm 20 is pivotally supported on the pivot shaft 12, and the front bell crank 13 is connected to the relay arm 20 and the fuselage frame 1 in a removable manner. A front and rear wheel steering mechanism for a power transport vehicle configured so that only a relay arm 20 can be operated integrally or by fixing a front bell crank 13.
