In addition, the interval h between the one rail line 21a and the other rail line 21b is formed at an interval larger than the diameter of the rotor 12 in consideration of the diameter of the rotor 12. In addition, the rail portion 20 is shown in a straight line for ease of description in the drawings, but may be formed in a curved, closed curve or open line shape.

On the other hand, the one side and the other side rail line (21a, 21b), the upper portion is formed of one polar portion 211 (for example, N polarity), the lower portion is formed of a bipolar portion 212 (for example, S polarity) do.

In addition, at one end (left end in FIG. 1) on the one side rail line 21a and the other end (right end in FIG. 1) of the other rail line 21b, the direction change for changing the traveling direction of the propulsion part 10 is performed.

When the first rotating body 12a is in contact with the protruding portion 23a of the insulator during the advancement of the propulsion unit, the attraction force is released while falling from the one polar portion of the other rail line 21b, so that the first rotating body 12a is released. Is separated from the other rail line 21b (specifically, is separated from the one polar portion 211 of the upper portion of the rail line 21b).

At this time, the one polar portion 211 of the one side rail line 21a facing the protrusion 23a rotates counterclockwise as the attraction force acts on the bipolar portion 122 of the first rotating body 12a. The bipolar portion 122 of the first rotating body 12a is attached.

The pushing section 10 is advanced in the downward direction of the drawing (see Fig. 7 (a)).

Then, when the first rotating body 12a comes in contact with the insulator portion 23b during the advancement of the propulsion unit, the attraction force from the other rail line is released as the contact with the one polar portion of the other rail line 21b is released. The first rotating body 12a is separated from the other rail line 21b (specifically, is separated from the one polar portion 211 of the upper portion of the rail line 21b).

At this time, the one polar portion 211 of the one side rail line 21a facing the insulator portion 23b rotates counterclockwise as the attraction force acts on the dipolar portion 122 of the first rotating body 12a. The bipolar portion 122 of the first rotating body 12a is attached.
