Then, when the motor 4 is reversed, the rear wheel drive axle 3 is reversed, and at the same time, the transmission shaft 31 is also reversed through the intermediate gear 12, and the small gear 30 of the transmission shaft 31 connects the shaft support through the rocking tooth portion 29. 25 is swung, and the upright arm 24 is swung around the rear drive axle 3. This swinging of the upright arm 24 brings the toy body A into an upright state with its rear end touching the ground, and this upright state causes the rear wheels 16 to separate from the floor, causing the toy body A to come to a stopped state. In addition, the intermediate gear 12 of the rear drive axle 3, the transmission reduction gear 33, the transmission gear 13,
Standing turning wheel 38 via standing turning gear 37
rotates, causing the toy main body A in an upright state to intermittently pivot around one side of its rear end.

Furthermore, when the toy body A is erected, the central portion 41 of the bumper protrudes through the connecting rod 42, making the shape of the toy main body A even more similar to that of a robot.
Furthermore, the arm 45 of this robot is attached to the front wheel axle 2 between the front wheel 44 and the chassis 1 so that it can rotate freely with some resistance when the robot stands up and changes its form to the robot form. be. Moreover, front wheel axle 2
is arranged on the chassis 1 in a non-rotatable manner. The arm 45 is engaged with the chassis erecting body 14, and is formed so as to separate from the notch 25A of the shaft support 25 when standing up, and to swing upward by being pushed by the edge of the notch 25A. When changing its shape to a traveling toy, it is pushed by the upright arm 24 and swings back to the side of the chassis 1, which is its original position.

Although not shown, the turning wheels 38 when standing up
are provided not only on one side but also on the other side of the rear end of the toy main body A, and the protruding positions of the protruding parts 39 of these swing wheels 38 are shifted by, for example, 90 degrees, so that the toy can stand upright. When transformed into a robot toy, it will be able to walk forward. In the illustrated example, the running toy is a car, but for example,
Of course, it may also take the form of a tank, airplane, spaceship, etc.

Note that the operating method of the present invention does not matter whether it is a wired method or a wireless method. In addition, the direction change is performed by turning the toy main body A around one side of the rear end of the toy main body A when standing up, but the present invention is not limited to this. A conversion device may be attached to change direction during forward travel.
