PURPOSE:To make it easy to assemble and ajust of the drive mechanism, steering mechanism, brake mechanism and reversing mechanism of an all-direction- movable truck and attach and detach these mechanism to and from the body frame of the truck, by building the mechanisms in units to be attached to the body frame of the truck. CONSTITUTION:Driving-side moving units U1 and driven-side moving units U2 are provided at the front, rear, right and left of a square body frame 1 so that the moving units are in prescribed positional relations to each other. The driving-side moving unit U1 comprises a steering mechanism S including a steering shaft 8, and a drive mechanism K, which functions so that a driving wheel 4 rotatably attached to a rotary body 3 is turned by a moving motor 6 through a speed reducer 5. The driven-side moving unit U2 comprises a steering mechanism S similar to said steering mechanism, and a brake mechanism B including a nonexcitation applied brake 16 coupled to an axle 14a through a speed reducer 15 and a clutch 17. Each steering mechanism S is actuated by a reversing mechanism R removably mounted. |
