The locking lever 25 is rotatably supported by the device main body 11 at a substantially intermediate position, and has a locking pawl 25a at its tip and a push button portion 25b at its rear end. Further, the tip thereof is pushed downward by a spring 26, and the locking pawl 25a is always located so as to protrude downward from the opening 11c.

Note that 27 is a power source for the motor 13 provided in the lower part of the base portion 11a of the main body 11, and 28 is a drive switch for the motor 13.

Next, the operation of the traveling toy device constructed as described above will be explained with reference to FIGS. 6a to 6c. First, as shown in FIG. 2, the projection 2a on the top of the body 2 of the traveling toy 1 is hooked onto the locking pawl 25a of the locking lever 25 protruding from the opening 11c, and the transmission receiving gear 4b-
1 and 4b-2 are brought into mesh with the transmission gears 19-1 and 19-2 via the openings 2-1 and 2-2. Next, the adjustment levers 20-1 and 20-2 are operated to select the rotation direction of the flywheels 4a-1 and 4a-2 of the flywheel power units 4-1 and 4-2, and the motor 13 is driven. .

At this time, the adjustment levers 20-1 and 20-2 are in the position shown in FIG. 6a, and the drive shaft 16 is connected to the motor 1.
3 rotates in the direction of the arrow, the transmission gears 19-1 and 19-2 rotate in the direction of the arrow, respectively, and the flywheels 4a-1 and 4a-2 of the traveling toy 1 have transmission receiving gears 4b-1 and 4b. -2, the rotation in the forward direction is transmitted respectively. Therefore, in this case, the push button part 25b is pushed and the locking pawl 25a is moved to the protrusion 2a.
When released from , the traveling toy 1 moves to the flywheel 4
The rotation of a-1 and 4a-2 causes the vehicle to travel straight forward. Note that in this embodiment, the transmission gears 19-1,
While receiving rotational force from 19-2, running toy 1
The rear wheels 5-1 and 5-2 are spinning idly while remaining in contact with the floor, but the traveling toy 1 is connected to the external power transmission device 1.
It is also possible to make the rear wheels 5-1 and 5-2 float above the floor when set to 0. In this case, there is no resistance applied to the rear wheels 5-1, 5-2, resulting in efficient power transmission.

Next, as shown in FIG. 6b, the adjustment lever 20-1
When the adjustment lever 20-2 is set to the intermediate position and the adjustment lever 20-2 is set to the rear position, only the transmission gear 19-2 rotates in the direction of the arrow, and as a result, only the flywheel 4a-2 of the flywheel power unit 4-2 rotates in the forward direction. introduce. At this time, when the locking pawl 25a is removed, only the rear wheel 5-2 rotates due to the rotation of the flywheel 4a-2, so that the traveling toy 1 rotates counterclockwise.

Further, as shown in FIG. 6c, the adjustment lever 20-
When both transmission gears 1 and 20-2 are set to the rear position, the transmission gears 19-1 and 19-2 rotate in the directions of the arrows, so rotation in the backward direction is transmitted to the flywheel 4a-1. -2
Rotation in the forward direction is transmitted to. As a result, the running toy 1 performs a counterclockwise spin operation because the left and right rear wheels 5-1 and 5-2 rotate in opposite directions.

As described above, according to the traveling toy device of this embodiment,
By adjusting the adjustment levers 20-1 and 20-2, the traveling toy 1 can be made to travel in a variety of ways. In addition, Fig. 6 a, b, c
is an example of the operation using the adjustment levers 20-1, 20-2.
It goes without saying that different transmission states can be selected by adjusting the position of 20-2.

Furthermore, the rotational force transmitted to the flywheels 4a-1, 4a-2 is changed by making the gear ratios of the transmission gears 19-1, 19-2 and the transmission receiving gears 4b-1, 4b-2 different on the left and right sides. Further, by making the rotational forces etc. of the flywheel power units 4-1 and 4-2 different from each other, more varied running conditions can be obtained. For example, if the rotational force of the flywheel power device 4-1 of the traveling toy 1 is made small and the endurance is large, and the rotational force of the flywheel power device 4-2 is made large and the endurance is small, the traveling toy 1 is Since the vehicle first travels counterclockwise and then clockwise, it is possible to realize S-shaped travel. Further, if the flywheel power units 4-1 and 4-2 are configured to have the same rotational force and different endurance, it becomes possible to perform a U-turn or the like. Various other driving conditions are possible.

In addition, on both sides of the lower part of the base portion 11a of the apparatus main body 11, as shown in FIGS. 1 and 3, regulating plates 30, 30 are foldably provided and extend at a predetermined angle. The regulating plates 30, 30 are for causing the traveling toy 1 to bounce back and travel forward when the traveling toy 1 runs backward.

Further, FIG. 7 is an external perspective view of a traveling toy device according to an embodiment of the present invention. In this example,
The device main body 11 of the external power transmission device 10 is shaped like a loading platform for the traveling toy 1, and is provided with wheels 35. With this structure, only the traveling toy 1 can be made to travel by pressing the push button portion 25b of the locking lever, and the device main body 11 can also be made to travel together with the traveling toy 1.

In the above embodiment, the traveling toy 1 is a toy car, but any type of toy can be used as long as it travels on a flywheel. Further, the external power transmission device 10 is not limited to the structure shown in the drawings, and may be configured to transmit power using two motors, respectively.

[Effects of the Invention] As explained above, according to the present invention, a traveling toy is provided with a pair of flywheel power devices that independently drive left and right drive wheels, and rotational force is transmitted to each of the flywheel power devices. By equipping the external power transmission device with a power transmission mechanism, it is possible to change the rotational force, rotation direction, etc. transmitted to the flywheels of the left and right flywheel power devices, making it possible to obtain extremely variable running conditions.
Further, since rotational force can be applied to the flywheel from the outside, there is no need to rub the drive wheel against the floor surface as in the past, which increases interest in playing with the traveling toy.
