An all-direction-changing mechanism and a driving power transmission mechanism combined together comprising a plurality of connecting rods radially extending from a connecting center, direction-changing cranks on the outer ends of the connecting rod controlling the direction of wheels mounted on the cranks, the ends of the connecting rods being connected with said direction-changing cranks by direction-changing crank pins, the connecting center being a center crank fastened to a steering mechanism mounted on a revolving vehicle body so that when the steering wheel is turned around for changing the vehicle's running direction, the connecting rods are also moved in parallel to one another, and as a result the vehicle body and all the wheels also change direction in the same angle. The driving power transmission mechanism is constituted by placing its axles, flat gears and bevel gears inside the direction-changing mechanism and arranging it so that every wheel receives its driving power from a chain and two chain sprockets that are revolved by a set of bevel gears one of which is mounted on a coupling rod which is rotated by the gears on the direction changing crank which receive power from gears on power transmission shafts inside the connection rods whereby all the wheels run at equal speed.
