Claims

[Scope of Claim for Utility Model Registration] A four-wheel drive device for a traveling toy that meets the following requirements. (b) A power unit that incorporates a mainspring as a driving power source and a gear device for transmitting driving power, through which a first drive shaft with wheels attached at both ends is inserted, and a second drive shaft with wheels attached to both ends. It is provided separately from the shaft. (b) A crown gear is provided on each of the first and second drive shafts. (c) One end of the connecting shaft with pinion gears provided at both ends is inserted and supported into the power unit to mesh with the crown gear of the first drive shaft, and the other end is projected from the power unit to support the second drive shaft. It can be freely engaged with the crown gear of the drive shaft.
