【Example】

 In the embodiment shown in the figure, a casing 4 is formed by fixing two hard plastic facing plates 1 and 2 to face each other with a lateral pin portion 3. The hard plastic winding shaft 6, the hard plastic first moving shaft 7a, the hard plastic second moving shaft 7b, and the idle shaft 8 are rotatably supported in a laterally parallel arrangement.

A drive gear 10 is fixed to the drive shaft 5 so as not to rotate, and a large-diameter first transmission gear 11 and a small-diameter second transmission gear 12 that mesh with the drive gear 10 are fixed to the idle shaft 8. A winding gear 13 and a third transmission gear 14 are respectively provided in advance on the winding shaft 6 by integral molding, and a mainspring drum 15 surrounding one end of the winding shaft 6 is provided on the side wall of the machine housing 4 in advance by integral molding.

The boss of the third transmission gear 14 is inserted into the drum 15, and the inner end of the mainspring 18 loaded into the drum 15 is inserted into the boss. Are respectively locked in a large number of locking grooves 20 provided on the inner peripheral surface of the drum 15.

The bearing hole of the first moving shaft 7 a is formed as a first elongated hole 22 a having one end close to the winding shaft 6 and the other end remote from the winding shaft 6. A first binion 23a that meshes with the winding gear 13 only during operation is provided in advance by integral molding.

The support hole of the second moving shaft 7b is formed as a second elongated hole 22b having one end farther from the winding shaft 6 and the other end closer thereto, and the second moving shaft 7b is used to release the mainspring 18. Only at the time, the second vinylon 23b meshing with the third transmission gear 14 and the spur gear 24 meshing with the second transmission gear 12 are provided in advance by integral molding.

Furthermore, the drive wheels 25 and 26 are fixed to both ends of the drive shaft 5 in a non-rotatable manner, thereby forming a spring unit 26 with drive wheels.

The mainspring unit 27 is configured such that the driven wheels and the drive wheels 25 and 26 are set in a vehicle body provided with driven wheels (not shown) so that the driven wheels 25 and 26 can be placed on the floor to obtain a finished product. It is.

When the entire mainspring unit 27 is moved rearward with the drive wheels 25 and 26 landing on the ground, the first vinylon 23 a meshes with the winding gear 13 to store energy in the mainspring 18. When the vehicle is released on the floor in a state of accumulation, the second vinylon 23b is used as the third transmission gear 14, the spur gear 24 is used as the second transmission gear 12, and the first transmission gear 11 is used as the drive gear 10, respectively. The driving wheels 25 and 26 rotate in a direction of traveling forward by meshing with each other.
