ABSTRACT:
A steering device for an automotive vehicle toy comprises a motor to be driven by a remote control operation, a steering mechanism having a return spring for biasing steering wheels into a neutral position, and a clutch for transmitting a driving force of the electric motor to the steering mechanism against the return spring. The clutch includes a holding disc, clutch elements engageable with the holding disc such that the clutch elements can be moved in a radial direction of the holding disc by a centrifugal force, and an outer cylindrical member concentrically accommodating the holding disc and the clutch elements in it, and firmly secured to the mechanical reduction gear. A plurality of engaging groove portions are formed in the holding disc at equal spaces through a partition wall. An engaging element engageable with the engaging groove portions is formed on an inner side of that outer peripheral portion of each clutch element which is brought into pressure contact with an inner peripheral surface of the outer cylindrical member. Each engaging element has a cut portion engageable with the partition wall. The clutch elements are engaged with either the engaging grooves or the partition wall such that the clutch elements are slidable in the radial direction.
