The base body of the traveling toy according to the present invention is provided with a coil for generating magnetic poles by passing an electric current, and the swing body is swingably attached to the upper portion of the base body. A weight is provided on the oscillating body, and urges the oscillating body to oscillate in a direction opposite to the traveling direction. Further, a permanent magnet is provided on the oscillator, and the permanent magnet acts on the magnetic pole of the coil to swing the oscillator in the traveling direction against the biasing force of the weight. At this time, the weight provided on the rocking body also rocks integrally in the traveling direction, so that the entire traveling toy slightly vibrates. Therefore, by intermittently supplying an electric current to the coil, the oscillating body having a weight periodically oscillates to cause a slight vibration of the traveling toy as a whole, and a forward propulsive force is obtained by the minute vibration. As described above, since the driving source using the magnetic action of the permanent magnet and the coil is used for traveling without using the rotational driving force of the prime mover, the structure can be simplified. While reducing the size of the toy body, it is possible to add some fun to the operation when traveling.

And constitute a circuit portion for intermittently supplying a current to the coil 15.

Next, the operation will be described. First, traveling toy 1
In the stopped state, no magnetic pole is generated in the coil 15 and no attractive force or repulsive force is generated between the coil 15 and the permanent magnet 25. Therefore, the weight 27 urges the swinging body 9 to swing in the swinging direction of the swinging body 9 in the direction opposite to the traveling direction F of the toy body 3, that is, in the clockwise direction FR shown in FIG. Next, when the slide switch 33 is turned on, the battery power from the power supply circuit 35 causes the pulse generation circuit 3 to operate.
7, supplied to the pulse supply circuit 39. When the pulse supply circuit 39 receives a pulse of a predetermined cycle from the pulse generation circuit 37, it outputs a pulse voltage of a predetermined pulse width to the coil 15 based on this pulse. This allows the coil 1
Since the pulse current flows intermittently in the magnetic pole 5, a magnetic pole N is periodically generated at the end of the coil 15 on the side facing the permanent magnet 25 according to the cycle of the pulse current. Coil 1 like this
When the magnetic pole N is generated on the magnetic pole 5, an attractive force is generated between the magnetic pole N and the magnetic pole S of the permanent magnet 25. First, when an attractive force is generated between the coil 15 and the permanent magnet 25 by the first pulse current,
The swinging body 9 is swung in the traveling direction F against the biasing force of the weight 27. That is, the oscillating body 9 rotates about the shaft 20 in the counterclockwise direction FL shown in FIG. At this time, the entire base body 7 is inclined forward and upward with respect to the traveling direction F due to the interposition of the protrusion 11a, and when the swinging body 9 swings integrally with the weight 27 in the traveling direction F, the traveling toy 3 as a whole is moved. Causes a slight vibration, and a propulsive force to the front F is obtained by the slight vibration. Then, in the rest period after the first pulse current flows until the next pulse current is supplied, no magnetic pole is generated in the coil 15 and an attractive force is generated between the coil 15 and the permanent magnet 25. Absent. Therefore, in the rest period, the weight 2
7 rotates the oscillating body 9 in the clockwise direction FR. As a result, the oscillating body 9 is returned to the original rest position.

The above-described operation is repeated according to the cycle of the pulse current, and the rocking body 9 cyclically rocks around the shaft 20. As described above, by periodically supplying the pulse current to the coil 15, the oscillating body 9 having the weight 27 periodically oscillates in the traveling direction F to cause a slight vibration in the traveling toy 3 as a whole. Vibration provides forward thrust. Therefore, since the forward propulsive force is obtained by the microvibration generated when the oscillating body 9 periodically oscillates in the traveling direction F, the traveling toy 3 travels as if it were traveling with sliding feet. The pulse width and pulse period of the pulse supplied to the coil 15 are set to appropriate values in consideration of the rocking speed of the rocking body 9.
