ABSTRACT:
The present invention relates to a children's car that moves forward with a simple and easy operation with particular care taken of the safety of the child riding the car. A steering block which can be steered with a steering wheel and a steering column is provided at the front of the car body. Drive wheels having a ratchet wheel are provided on opposed sides of the steering block. Auxiliary wheels are provided at the front and the rear of the steering block to stably support the car body. As a child sits on or in the car and turns the steering wheel in alternating directions, the right and left drive wheels rotate in a forward direction. A pawl linked to the steering block engages the ratchet wheels to prevent inverse rotation of the drive wheels, causing the car to proceed ahead in a zig-zag pattern.
