Needless to say, a non-magnetic case containing the left and right second permanent magnets 81 and 83 may be provided, and the lower ends of the left and right standing portions 11 and 13 and the wheels 5E and 5F may be attached to this case. ..

In the present embodiment, the left and right second permanent magnets 81 and 83 are arranged along the first direction (parallel to the first direction) indicated by the arrow A, which is different from the above-mentioned first embodiment and the like. (In other words, the moving body 70 of the present embodiment also has a fixing function for fixing the left and right permanent magnets 81 and 83, and the upstream and downstream first permanent magnets 61 and 63, similarly to the moving body 5 described above. It can be said that it has a maintenance function for maintaining the positional relationship, and has a regulation function in the left and right standing portions 11, 13 and the connecting portion 15 of the moving body 70). Specifically, the left and right second permanent magnets 81 and 83 are formed in a plate shape having both side surfaces parallel to each other and perpendicular to the plane G, and upper and lower surfaces parallel to each other. The left and right second permanent magnets 81 and 83 are fixed to the left and right upright portions 11 and 13 so as to be perpendicular to the plane G and in the direction along the first movement direction (parallel to the first movement direction). When the moving body 70 is placed on the plane G, the right side surfaces 81b of the left second permanent magnet 81 and the left side surfaces 61a and 63a of the upstream and downstream first permanent magnets 61 have the same polarity and are these. Are in a positional relationship facing each other. Further, the left side surface 83b of the right second permanent magnet 83 and the right side surfaces 61b and 63b of the upstream and downstream first permanent magnets 61 have the same polarity, and they are in a positional relationship facing each other. ing.

Further, the left and right second permanent magnets 81 and 83 also have an upper portion and a lower portion with the center line CL5 passing through the center in the height direction as a boundary, respectively. When the moving body 70 is placed on the plane G, the center lines CL5 of the left and right second permanent magnets 81 and 83 are the upstream end of the center line CL4 of the upstream first permanent magnet 61 and the downstream side first. The upstream end of the center line CL4 of the one permanent magnet 63 (in other words, the downstream end of the lower surface 61d of the upstream first permanent magnet 61) and the downstream end of the lower surface 63d of the downstream first permanent magnet 63. It is designed to be the same as the connecting line. In other words, the left and right second permanent magnets 81 and 83 are fixed to the moving body 70 so that their center lines CL5 are located below the center lines CL4 of the upstream and downstream first permanent magnets 61 and 63. It can be said that it is. The second permanent magnets 81 and 83 may be fixed to the moving body 70 so that the center line CL5 is located below the center line CL4.

Here, in the above-described embodiment, the distance between the upstream end of the right side surface 17b of the second permanent magnet 17 in the space S2 and the left side surface 3a of the first permanent magnet 3 and the second in the space S3. It was to vary the distance between the downstream end and the left side surface 3a of the first permanent magnet 3 of the right side surface 17b of the permanent magnet 17. In other words, in the above-described embodiment, it was to change the distance between the permanent magnets facing the same poles. On the other hand, the present embodiment is different from the above-described embodiment in that the overlapping range of the facing surfaces of the permanent magnets facing each other with the same poles is generally changed. Next, this will be described.

First, as shown in FIGS. 6 (b) and 7 (a), when the upstream first permanent magnet 61 is placed on the plane G, the rightmost left second permanent magnet in FIG. 6 (b) is placed. When the center line CL5 is located at the center position corresponding to the center line CL4 of the upstream first permanent magnet 61 as in 81, the repulsive force between the upstream first permanent magnet 61 and the second permanent magnet 81. Are balanced in the vertical direction. On the other hand, in the left-right direction, the upstream first permanent magnet 81 is larger, so that the left second permanent magnet is the side surface 31a of the upstream first permanent magnet 81 as shown by the arrow Y in FIG. 7 (a). Although it receives a repulsive force in the direction vertically away from, the right second permanent magnet 83 ( not shown in FIGS. 6 and 7 ) is also located at the same center position on the opposite side of the left second permanent magnet 81. Since the right second permanent magnet 83 also receives a repulsive force in a direction vertically away from the side surface 31b of the upstream first permanent magnet 81 (direction opposite to the arrow Y1), the upstream first permanent magnet 61 and the second permanent magnet 81 The repulsive force between and is balanced even in the left-right direction.

Further, as in the leftmost left second permanent magnet 81 in FIG. 6B, the center line CL5 is located above the center line CL4 of the upstream first permanent magnet 61. In this case, a repulsive force is applied in the direction indicated by the arrow G in FIGS. 6 (b) and 7 (a) (inward diagonally upward to the right when viewed in FIG. 7 (a)), and the right second permanent magnet 81 is opposite to the left second permanent magnet 81. Since the two permanent magnets 81 and 83 receive a repulsive force diagonally upward to the left as seen in FIG. 7A, the moving body 70 to which the left and right second permanent magnets 81 and 83 are fixed is directed upward. A repulsive force acts, and as a result, the moving body 70 floats upward.

Further, when the center line CL5 is located below the center line CL4 of the upstream first permanent magnet 61 as in the central left second permanent magnet 81 in FIG. 6 (b), it is located at a lower position. Repulsive force is applied in the direction indicated by the arrow H in FIGS. 6 (b) and 7 (a) (diagonally downward to the right when viewed in FIG. 7 (a)), and the right second permanent magnet 81 is opposite to the left second permanent magnet 81. Since the magnets 81 and 83 receive a repulsive force diagonally downward to the left as seen in FIG. 7A, the moving body 70 to which the left and right second permanent magnets 81 and 83 are fixed has a downward repulsive force. It acts, and as a result, the moving body 70 is pressed against the lower plane G. In this specification, FIG. 7B is treated as absent.

It will be in the state of being done.

The first permanent magnet 61 upstream, since the inclined upward to the left in FIG. 5 (b), the upstream side in the upstream side first permanent magnets 61 gradually toward the (left side in FIG. 5), upstream The space S5 formed between the bottom surface 61d of the first permanent magnet 61 and the plane G becomes large. When the upstream first permanent magnet 61 is located between the left and right second permanent magnets 81 and 83 fixed to the moving body 70 on both sides of the upstream first permanent magnet 61, the left first permanent magnet 61 is located. The right side surface 81b of the second permanent magnet 81 and the left side surface 83a of the right second permanent magnet 83 face both side surfaces 61a and 61b of the upstream first permanent magnet 61.

In this state, in the right side surface 81b of the left second permanent magnet 81, the range (area) facing the left side surface 61a of the upstream side first permanent magnet 61 gradually becomes smaller from the upstream side to the downstream side (in other words). Then, the range facing the space S5 gradually increases from the upstream side to the downstream side ). As a result, in the moving body 70 to which the left and right second permanent magnets 81 and 83 are fixed, the moving body 70 moves in the first direction indicated by the arrow A.

Further, as shown in FIG. 5A, when the downstream portions of the left and right second permanent magnets 81 and 83 fixed to the moving body 70 are located at positions facing the gap K. The distance between the downstream part and the upstream part (triangular column-shaped part) of the downstream first permanent magnet 83 is the upstream part of the left and right second permanent magnets 81 and 83 and the upstream first permanent magnet 81. It is longer than the distance from the downstream part (square pillar-shaped part) of. When the moving body 70 is lowered and set from above the upstream end of the downstream first permanent magnet 63, the moving body 70 is the first indicated by the arrow A as shown in FIGS. 8 (b) to 8 (c). Move in the direction .

Thus, it is possible with a simple configuration in which only inclining the first permanent magnet 6 3 Downstream side, the movement of the moving body 70. Further, by adjusting the inclination angle of the lower flow side first permanent magnet 63, it is possible to adjust the momentum or the like of the movement of the moving body 70.
