At this time, as shown in FIG. 10 and FIG. 4 and the like, since the wheel 6c is provided at a position eccentric from the shaft 12 on which the caster 6 is attached to the arm member 4, the wheel 6c and the table are moved forward. The caster 6 rotates in the clockwise direction in FIG. When the caster 6 rotates in this way, the projection 6d of the caster 6 and the engaging portion 4d of the arm member 4 are engaged to restrict the rotation at a set angle, and the wheel 6c is set as shown in FIG. It will be fixed at an angle. As a result, in this embodiment, as shown in FIG. 14, the vehicle starts moving forward from position A, and the caster 6 is steered leftward by rotating a set angle to travel in the direction of position B.

  Thereafter, when both or one of the wheels 6c are removed from the edge of the table when traveling to the position C, the other end 4b of the arm member 4 is moved downward together with the casters 6 as shown in FIG. As a result, the switch 38 is turned on, a signal is output from the up / down detection unit 24 to the switching unit 34, and the motor unit 20 is reversed by the motor driving unit 30. Thereby, the traveling toy with a steering function starts retreating. At this time, as shown in FIGS. 12 and 4, the caster 6 rotates counterclockwise, the projection 6 d engages with the engagement portion 4 c of the arm member 4, and the wheel 6 c is set.

As a result, in this embodiment, as shown in FIG. 14, the vehicle starts to move backward from the position C, and the caster 6 is steered to the right by rotating the set angle to travel in the direction of the position D.

  When the position D is reached, the timer 36 that starts counting with the backward movement counts up, whereby the switching unit 34 switches the motor driving unit 30 to rotate the motor unit 20 in the normal direction. Thereby, the traveling toy with a steering function starts moving forward again. When the vehicle moves forward in this way, as shown in FIG. 13, the caster 6 rotates again in the clockwise direction, and its projection 6d engages with the engaging portion 4d of the arm member 4 and is steered to the left to continue running. become.

  In addition, when a sound with a certain sound pressure or higher is generated by colliding with an obstacle or hitting a hand, the sound detection unit 26 detects the sound and moves backward to the right for a certain time in the same manner as described above. , Will move left again.

  In addition, even if the vehicle does not derail or collide with an obstacle while traveling, if the vehicle travels for a certain period of time, the time detection unit 28 detects it and moves backward to the right for a certain period of time in the same way as described above. Will move forward.

  Furthermore, since the front surface of the main body 2 is formed into a spherical curved surface as shown in FIGS. 2 and 3 when it collides with an obstacle, the main body 2 can easily ride on the obstacle. Also in this case, when the main body 2 is lifted, the caster 6 is lowered, and the switch 38 is turned on in the same manner as when the wheel 6c is removed from the wheel 6c, and is moved backward to the right for a certain time. This makes it possible to move forward again, avoiding obstacles.
