A guide hole is formed in the plate along the direction connecting the non-circular recesses, a shaft is inserted into the guide hole, a spring abutting body is provided at the tip of the shaft, and the shaft is attached to and detached from the non-circular recess. It has a structure characterized in that a non-circular fitting body having a similar shape to the non-circular recess that is freely fitted is provided, and a pressing spring is provided between the spring abutting body of the shaft and the second plate.

When the wheel body is pulled to the other side with respect to the working shaft, the second plate compresses the pressure spring and the non-circular mating body plate is disengaged from the non-circular recess.

Next, when the wheel body is moved and the shaft is slid along the guide hole and the hand is released, the second plate is pushed by the restoring force of the suppression spring, and the spring abutting body abuts the second plate and is fitted. The union is fitted into another non-circular recess.

Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Fig. 1 shows the wheel mounting part, in which a first plate consisting of a shaft holding plate 2 and a second plate consisting of a position adjustment plate 3 are provided in parallel with an interval at the tip of a shaft 1. A tire 4 made of rubber, synthetic resin, etc. is fitted around the outer periphery of the wheel body 2 and the position adjustment plate 3 to form a wheel body IA, and the wheel body IA is attached to both ends of the shaft 1, respectively, as in conventional running toys. There is.

The shaft holding plate 2 and the position adjustment plate 3 are made of hard synthetic resin and have a substantially identical disc shape, and one surface of the shaft holding plate 2 has three fitting recesses as shown in FIG. 5
are formed at intervals along the diameter, and screw holes 6 are drilled near both ends on the diameter perpendicular to these.

As shown in FIG. 3, on one side of the position adjustment plate 3, a non-circular recess of the same shape consisting of three hexagonal rectangular recesses 7 corresponding to the fitting recess 5 of the shaft holding plate 2 is provided in the diametrical direction. At the bottoms of these rectangular recesses 7, elongated guide holes 8 are bored along the diametrical direction, which is the direction connecting the rectangular recesses 7, and on the other surfaces near both diametrical ends perpendicular to the guide holes 8. , a spacer 10 is implanted via an embedded screw 9.

Then, the surface of the shaft holding plate 2 where the fitting recess 5 is formed and the side of the position adjustment plate 3 where the spacer 10 is implanted are made to face each other, and the tip of the spacer 10 is inserted through the screw hole 6 from the outer surface of the shaft holding plate 2. A screw 11 is screwed in, and the shaft holding plate 2 and the position adjusting plate 3 are installed in parallel with an interval equal to the length of the spacer 10.

The shaft 1 is attached to a vehicle body 12 so as to be rotatable about its axis, as in the conventional traveling toy shown in FIG.
A circular spring contacting body 14 is fixed to the outer periphery of the distal end of the shaft 1 and has a convex portion 13 that removably fits into the fitting recess 5 of the shaft holding plate 2. A spring pressing plate 15 that contacts the inner surface of the position adjustment plate 3 is fitted inside the spring pressing plate 15 so as to be slidable in the axial direction of the shaft 1.

Further, a pressure spring consisting of a coil spring 16 is fitted on the outer periphery of the shaft 1 between the spring contact body 14 and the position adjustment plate, and whose both ends abut against the spring contact body 14 and the spring pressing plate 15. At a position further inward of the pressing plate 15 sandwiching the position adjustment plate 3, there is a non-circular fitting body having a similar shape to the rectangular recess 7 and made of a hexagonal rectangular plate 17 that removably fits into the rectangular recess 7. Fixed and installed.

Next, the operating method of the above embodiment will be explained.

When changing the relative position of the wheel body IA with respect to the shaft 1, as shown in FIG.
Then, the square plates 17 are pulled out from the square recesses 7, and the position adjustment plate 3 presses the spring pressing plate 15 outward, and the spring pressing plate 15 compresses the coil spring 16.

In this state, when the wheel body r-A is moved parallel to the guide hole 8, the shaft 1 slides along the guide hole 8, and when the hand is released at an appropriate position, the coil spring 1-6 springs due to the restoring force. The suppressing plate 15 is pushed toward the center of the shaft 1, and the spring pressing plate 15 pushes the position adjusting plate 3 in the same direction, so that the wheel body IA moves inward, and the convex portion 13 at the tip of the shaft 1 is pushed toward the center of the shaft 1. It fits into the recess 5, and the square plate 17 fits into another square recess 7.

When the convex portion 13 and the square plate 17 fit into the central fitting recess 5 and the square recess 7, respectively, the shaft 1 and the wheel body IA
However, when the protrusion 13 and the square plate 17 fit into the fitting recess 5 and the square recess 7 at the end, the wheel body IA
is attached eccentrically to the shaft 1.

When eccentric in this manner, the running toy runs while rocking up and down, and when the front, rear, left, and right tires 4 are mounted asymmetrically, the running toy swings irregularly.

In the embodiment shown in FIG. 5, guide walls 19 are further provided in parallel on both sides of the fitting recess 5, so that the spring contact body 14 does not slide between these guide walls 19 and come off. 1 and the wheel body IA are stably moved.

In the above embodiment, the tire 4 was provided on both the shaft holding plate 2 and the position adjusting plate 3, but the tire 4 may be provided only on one of the shaft holding plate 2 and the position adjusting plate 3, and the tire 4 may be provided on only one of the shaft holding plate 2 and the position adjusting plate 3. 7 can be provided on the shaft holding plate 2, and the spring contact body 14 can be made into a square shape similar to the square recess 7 that fits into this square recess 7. Also, the square plate 17 and the square recess 7 are not necessarily Instead of a hexagonal shape, make it a rectangular shape.

But that's fine.

Effects of the Invention Since the wheel of the traveling toy of the present invention has the above configuration, the plurality of non-circular recesses provided in at least one of the first plate and the second plate are connected to the fitting body provided on the shaft. By selecting one properly and fitting them together, you can change the running conditions in a variety of ways, which is very interesting. The position of the wheel body relative to the shaft can be easily changed by simply releasing the wheel body without removing the wheel body.

In addition, since the spring abutting body is provided at the tip of the shaft, the spring abutting body acts as a stopper to prevent the wheel from falling off the shaft, and there is no need to worry about the wheel body falling off the shaft. Since the shaft engages with the non-circular recess provided in the shaft, the shaft will not spin idly.
