It passes through a disk 97 that is formed and has a shape that can be fitted inside the groove of the second gear 7. As a result, if the long shaft 85 is fitted into the cross-shaped center hole 99 of the disc 97 and the disc 97 is fitted into the protrusion 76 of the second gear 7, the second gear 7
can now rotate integrally with the long axis 85.

That is, the gondola member 25 is hung on a support rod 26 between a pair of left and right suspension brackets 27, and the suspension bracket 27 has a protrusion 28 on its side surface connected to a circular hole socket 73 formed on the plate surface of the second gear 7. It is attached to the second gear 7 by fitting into the second gear 7. Therefore, the gondola toy 24 is assembled on the floor board 3 with the gondola member 25 suspended between the opposing second gears 7.

Rotating floating wheel toy 1 and Ferries wheel toy 2
A large number of first gears are attached to the floor board 3 and the bar 41 and meshed with each other with their rotational axes in the horizontal or vertical direction, and second gears of each toy are meshed with the first gears. A gear train consists of.

It should also be mentioned that the support frame 44 supports the gear train so that one of the first gears 6 is engaged with the upper second gear 7, and the two bars 41 are placed side by side on the floor board 3. After assembling, a rod 41 can be further horizontally stretched across the upper side portion thereof and connected by a plug member 5 to form the structure.

Furthermore, the above-mentioned rotational movement can be driven by a model motor, and in this case, the motor is installed on the floor together with a battery as a power source in a case that can be attached by fitting the protrusion into the circular hole 32 or 42. It is attached to the substrate 3 or the support frame 44, and the rotational output is transmitted via known means such as an output shaft and gears.

In the above embodiment, the toy can be made even more interesting by attaching a ballet doll or the like to the first gear, and these modifications or changes do not depart from the spirit of the present invention. It is clear that it falls within the scope of the claims.
