Furthermore, the doll 41 with magnets 42, 42 attached to the soles of both feet is placed in a state where the magnets correspond to the magnets 23, 23 attached to the upper surface of both left and right ends of the rocker arm 21, through a synthetic resin sheet 43. Place it on the landing 26.

(f) Action The rotation of the horizontal shaft 3 is converted into piston motion by the crank 38, and transmitted to the actuating arm 35 by the connecting rod 36, and then transmitted through the horizontal shaft 33, the universal joint 47, the torque rod 30, and the universal joint 29 to the drive. The drive arm 28 repeatedly rotates the rocker arm 21 vertically like a seesaw.

Drive arm 28 allows Rotzker arm 21
When the right end of the rocker arm 21 is lowered, the magnet 23 on the upper surface of the right end of the rocker arm 21 is also lowered.

Since the landing 26 remains horizontal, the doll 41
The magnet 42 on the sole of the right foot and the magnet 23 on the upper surface of the right end of the Rocker arm 21 had hitherto been attracted to each other and held the synthetic resin sheet 43 between them, but now that the right end of the Rocker arm 21 has been lowered, As soon as they lose their attractive force, they separate, and as a result, the left end of the rocker arm 21 rises, so the magnet 42 on the sole of the left foot of the doll 41 and the magnet 23 on the upper surface of the left end of the rocker arm 21 attract each other and combine. The resin sheet 43 is held between the left and right feet, and the synthetic resin sheet 43 is securely held alternately.

While the rocker arm 21 is repeatedly rotated in the vertical direction in this manner, the crank 11 fixed to the lower end of the vertical shaft 7 of the box frame 6 is rotated to cause the connecting rod 12 to make a piston movement, thereby moving the inside of the cylindrical bearing 14. The operating arm 16 fixed to the lower end of the shaft 15 is moved left and right, and at the same time the landing base 18 fixed to the disk 17 at the upper end of the shaft 15 is repeatedly rotated half a turn in the left and right direction together with the landing 26 and the rocker arm 21. doll 4
Step 1's left and right legs move forward alternately.

In summary, in this invention, the landing 26 repeatedly rotates half a turn in the left and right direction while in contact with the lower surface of the synthetic resin sheet 43, and at the same time, the rocker arm 21 repeatedly rotates in the vertical direction. The magnets 23, 23 attached to the square holes 27, 27 of the landing 26
Move up and down repeatedly. Therefore, the doll 41 with magnets 42, 42 attached to the soles of both feet is placed on the synthetic resin sheet 43 with the magnets corresponding to the magnets 23, 23 of the rocker arm 21.
If the doll 41 is placed on the landing 26 through the magnets 23 and 2, the magnets 42 and 42 on the left and right legs move up and down repeatedly on the landing 26, where the magnets 42 and 42 rotate half a time repeatedly.
3, they are alternately drawn together via the synthetic resin sheet 43.

Therefore, the doll 41 moves forward together with the machine body below the synthetic resin sheet 43 while taking a walking posture on the synthetic resin sheet 43.

In addition, when going backwards, by rotating the motor in the opposite direction, the left and right legs can be moved backwards alternately using the same process as above.

(g) Effect of the invention The drive arm 28 allows the Rotsuker arm 2 to
By alternately moving the left and right ends of 1 up and down, the magnet 2 on the upper surface of both left and right ends of the rocker arm
