As shown in FIGS. 1 and 2, the thrust generating mechanism (thrust generating device) 1 according to the first embodiment includes a first permanent magnet 3 mounted and fixed on a flat surface G such as the ground or a floor. It has a non-magnetic moving body (moving portion) 5 that can move along the plane G. In the present embodiment, in the first permanent magnet 3 shown in FIGS. 1 and 2, the north pole is a white part and the south pole is a black part. The same applies to the first permanent magnet 3 and other permanent magnets in the drawings after FIG. In the present embodiment, the white part is the N pole and the black part is the S pole, but it goes without saying that the white part may be the S pole and the black part may be the N pole. The same applies to other embodiments other than the present embodiment, such as the second embodiment described later.

As shown in FIGS. 1A and 2, the first permanent magnet 3 is formed in a square columnar shape extending in a straight line. The left left portion 3A on the left side of FIG. 1A of the first permanent magnet 3 has an N pole magnetic pole, and the right right portion 3B on the right side has an S pole magnetic pole. In other words, the left side surface (first surface) 3a of the first permanent magnet 3 is the north pole, and the right side surface (second surface) 3b is the south pole. In the state where the first permanent magnet 3 is placed on the plane G (in the state shown in FIG. 1), the left side surface 3a and the right side surface 3b of the first permanent magnet 3 are respectively a vertical surface perpendicular to the plane G. (In other words, these left side surfaces 3a and right side surface 3b are parallel to each other). Further, in a state where the first permanent magnet 3 is placed on the plane G, the upper surface of the first permanent magnet 3 (upper surface as seen in FIG. 1) 3c and the lower surface of the first permanent magnet 3 (see FIG. 1). The lower surface 3d in contact with the plane G is a parallel surface parallel to the plane G (in other words, the upper surface 3c and the lower surface 3d are parallel to each other).

In the present embodiment, the first permanent magnet 3 is fixed to the plane G by its own weight, but instead of this, for example, a non-magnetic case in which the first permanent magnet 3 is enclosed is provided. , This case may be fixed to the flat surface G with a fixture such as a screw or adhesive. Further, in FIG. 1, between the plane G and the lower surface 3d of the first permanent magnet 3, and between the plane G and the lower surface of the moving body 5 (lower surfaces 7d and 9d of the left and right slide portions 7 and 9 described later). Although gaps are formed in each of them, they are formed to make the figure easier to see. In reality, the lower surface 3d of the first permanent magnet 3 and the lower surface of the moving body 5 and the plane G are It goes without saying that they are in contact.

In FIG. 1A, the moving body 5 is located on the left and right sides of the first permanent magnet 3, and is a non-magnetic left slide portion 7 and right slide portion 9 parallel to the plane G, and these slide portions 7. , 9 left standing portions 11 and right standing portions 13 of non-magnetic materials that stand up from the ends of the first permanent magnets 3 side in the direction perpendicular to the plane G, and the upper ends of these left and right standing portions 11, 13 In addition to connecting the parts, a non-magnetic connecting part 15 parallel to the plane G is provided. In the moving body 5, the moving body 5 is generally arranged so that the first permanent magnet 3 is accommodated in the internal space S1 formed by the left and right standing portions 11 and 13 and the connecting portion 15 (moving body 5 is arranged). By setting it in the first permanent magnet 3), it moves in the first direction indicated by the arrow A in FIG. 2 (this will be described later).

The left slide portion 7 and the right slide portion 9 are formed in a plate shape. On the upper surface 7a of the left slide portion 7, three second permanent magnets 17, 19, 21 formed in a plate shape (hereinafter, these may be collectively referred to as "second permanent magnet 17 or the like"). However, the three third permanent magnets 23, 25, and 27, which are fixed by an adhesive or the like and are also formed in a plate shape on the upper surface 9a of the right slide portion 9, (hereinafter, these are collectively referred to as "third permanent magnet". The magnet 23 and the like are sometimes referred to as "magnets 23 and the like") are fixed by an adhesive or the like. Further, the lower surface 7d of the left slide portion 7 and the lower surface 9d of the right slide portion 9 are parallel to the plane G.

Fixing the second permanent magnet 17 or the like to the upper surface 7a of the left slide portion 7 and fixing the third permanent magnet 23 or the like to the upper surface 9a of the right slide portion 9 is not limited to the above-mentioned adhesive or the like, for example, the left slide portion. Recesses may be formed in the upper surfaces 7a and 9a of the 7 and the right slide portion 9, and the lower portions of the second permanent magnet 17 and the like and the third permanent magnet 23 and the like may be fitted into these recesses, respectively. Further, a non-magnetic case in which the second permanent magnet 17 and the like and the third permanent magnet 23 and the like are enclosed is provided, and these cases are attached to the left slide portion 7 and the right slide portion, respectively, with fasteners such as screws and adhesives. It may be fixed by. In short, if the second permanent magnet 17 and the like and the third permanent magnet 23 and the like can be fixed to the upper surfaces 7a and 9a of the left slide portion 7 and the left slide portion 9, respectively, the fixing method thereof is as follows. Not particularly limited.

Next, the second permanent magnet 17 and the like will be described. Since the second permanent magnets 17, 19 and 21 all have the same configuration, only the second permanent magnet 17 will be described, and the second permanent magnet 19, Regarding 21, for example, the reference numerals 19A and 21A of the second permanent magnets 19 and 21 have the same reference numerals as those of the second permanent magnets 17, such that they correspond to the reference numerals 17A of the second permanent magnets 17. I will omit the explanation by doing so.

The left side surface 17a and the right side surface 17b of the second permanent magnet 17 are parallel to each other in a state of being fixed to the slide portion 7. Further, the upper surface 17c and the lower surface 17d of the second permanent magnet 17 (see FIG. 1A) are vertical surfaces perpendicular to the left side surface 17a and the right side surface 17b, and the upper surface 17c and the lower surface 17d are mutual. They are parallel (see FIG. 1 (a)). Further, the left left portion 17A on the left side of FIG. 2 of the second permanent magnet 17 has the magnetism of the S pole, the right portion 17B on the right side has the magnetism of the N pole, and the left side surface 17a of the second permanent magnet 17 has. Is the south pole, and the right side surface (opposing surface) 17b is the north pole. That is, the right side surface 17b of the second permanent magnet 17 faces (opposes) the left side surface 3a of the first permanent magnet 3. Further, the right side surface 17b of the second permanent magnet 17 and the left side surface 3a of the first permanent magnet 3 both have north poles, and a repulsive force is generated between them.

As shown in FIG. 2, the second permanent magnet 17 is fixed to the upper surface 7a of the left slide portion 7 so as to be inclined diagonally downward to the left in a plan view (as seen in FIG. 2). In other words, in the second permanent magnet 17, the distance between the right side surface 17b of the second permanent magnet 17 and the left side surface 3a of the first permanent magnet 3 gradually increases toward the first direction indicated by the arrow A. Is fixed to the upper surface 7a of the left slide portion 7. As a result, as shown in FIG. 3B, the end portion of the right side surface 17b of the second permanent magnet 17 on the upstream side (hereinafter, simply referred to as “upstream side”) in the first direction and the first permanent magnet 3 The distance L1 from the left side surface 3a is defined as the end of the right side surface 17a of the second permanent magnet 17 on the downstream side in the first direction (hereinafter, simply referred to as the “downstream side”) and the left side surface 3a of the first permanent magnet 3. The distance is smaller than the distance L2 (L1 <L2).

Therefore, as shown in FIG. 4, the repulsive force F1 in the space S2 between the upstream end of the right side surface 17b of the second permanent magnet 17 and the left side surface 3a of the first permanent magnet 3 is the second permanent magnet. The repulsive force F2 in the space S3 between the downstream end of the right side surface 17b of 17 and the left side surface 3a of the first permanent magnet 3 becomes larger (F1> F2). As described above, since the repulsive force F1 in the space S2 is larger than the repulsive force F2 in the space S3, a thrust P which is a component force acting in the first direction indicated by the arrow A is generated.

Further, the angle θ1 formed by the left side surface 3a of the first permanent magnet 3 and the right side surface 17b of the second permanent magnet 17 is within the range of 10 degrees or more and 27 degrees or less (10 degrees ≤ θ1 ≤ 27 degrees). It is preferable to do so. This is because when the angle θ1 is less than 10 degrees, the difference between the distances L1 and L2 described above is small, so that the thrust P required to move the moving body 5 does not work. Further, when the angle θ1 exceeds 27 degrees, an attractive force acts strongly between the left side surface 17a of the north pole of the second permanent magnet 17 and the left side surface 3a of the south pole of the first permanent magnet 3, and this attractive force hinders the thrust P. This is because the thrust P required to move the moving body 5 does not work. The angle θ1 is more preferably 22 degrees or more and 24 degrees or less (22 degrees ≦ θ1 ≦ 24 degrees).

Here, FIG. 3 (b) is a diagram schematically showing the positional relationship between the second permanent magnet 17 and the like, the third permanent magnet 23 and the like, and the first permanent magnet 3, and FIG. 3 (a) is a diagram (b). ) Is a front view seen from the direction of the arrow a, and (c) is a front view of the figure (b) seen from the direction of the arrow b. In FIG. 3, for convenience of explaining the positional relationship between the second permanent magnet 17 and the like, the third permanent magnet 23 and the like, and the first permanent magnet 3, the first permanent magnet 3 and the second permanent magnet 17 and the like in FIG. 2 are shown. The size is different from that of the third permanent magnet 23 and the like. The left portion 21A and the right portion 21B of the second permanent magnet 21, and the left portions 27A and 27B of the third permanent magnet 27 actually look like FIG. 3 (c), but FIG. 1 ( The left portion 21A and the right portion 21B of the second permanent magnet 21 and the left portion 27A and the right portion 27B of the third permanent magnet 27 in a) are simplified and drawn (left portion 27A and right portion 27B) for convenience of explanation. Needless to say, the widths in the left-right direction are drawn evenly.

In the present embodiment, as shown in FIG. 2, the second permanent magnets 17, 19 and 21 are arranged so as to be arranged vertically as seen in FIG. Further, the second permanent magnets 17, 19 and 21 have a line segment X1 connecting the leftmost ends of the second permanent magnets 17, 19 and 21 on the upper surface 7a of the slide portion 7, and the second permanent magnets 17, 19, 21. The line segment X2 connecting the rightmost ends of the magnet 3 is parallel to the left side surface 3a of the first permanent magnet 3.

Further, the downstream end of the second permanent magnet 17 and the upstream end of the second permanent magnet 19 are in a positional relationship adjacent to each other in a plan view, and the downstream end of the second permanent magnet 19 and the second permanent end. The upstream ends of the magnet 21 are also in a positional relationship adjacent to each other in a plan view. The positional relationship is not limited to such adjacent positions, and may be, for example, an overlapping positional relationship in which the downstream end of the second permanent magnet 19 and the upstream end of the second permanent magnet 21 slightly overlap. In short, as long as a sufficient thrust P is obtained, the positional relationship may be adjacent or overlapping. The same applies to the third permanent magnet 23 and the like, which will be described later.

Next, the third permanent magnet 23 and the like will be described. Since the third permanent magnets 23, 25 and 27 all have the same configuration, only the third permanent magnet 23 will be described, and the third permanent magnet 25, Regarding 27, for example, the reference numerals 25A and 27A of the third permanent magnets 25 and 27 are designated by the same reference numerals as the respective parts of the third permanent magnet 23, such that they correspond to the reference numerals 23A of the third permanent magnet 23. I will omit the explanation by doing so. Further, since the third permanent magnet 23 has the same configuration as the second permanent magnet 17 except for the inclination direction, the contents already described in the second permanent magnet 17 are referred to as the second permanent magnet 17. The description shall be omitted or simplified by adding a similar reference numeral.

As shown in FIG. 2, the left side surface (opposing surface) 23a of the third permanent magnet 23 and the right side surface 3b of the first permanent magnet 3 facing the left side surface (opposing surface) 23a are S poles, respectively, and a repulsive force is formed between them. Is coming to occur. Further, the third permanent magnet 23 is fixed to the upper surface 9a of the right slide portion 9 so as to be inclined diagonally downward to the right in a plan view (as seen in FIG. 2). In other words, in the third permanent magnet 23, the distance between the left side surface 23a of the third permanent magnet 23 and the right side surface 3b of the first permanent magnet 3 gradually increases toward the first direction indicated by the arrow A. Is fixed to the upper surface 9a of the right slide portion 9. The angle θ2 formed by the left side surface 23a of the third permanent magnet 23 and the right side surface 3b of the first permanent magnet 3 is the same as the above-mentioned θ1. Further, the third permanent magnets 23, 25, 27 have a line segment X3 connecting the leftmost ends of the second permanent magnets 23, 25, 27 on the upper surface 9a of the slide portion 9, and the second permanent magnets 23, 25, 27, respectively. The line segment X4 connecting the rightmost ends of the magnet 3 is parallel to the right side surface 3b of the first permanent magnet 3.

As a result, as shown in FIG. 3B, the distance L3 between the upstream end of the left side surface 23a of the third permanent magnet 23 and the right side surface 3b of the first permanent magnet 3 (note that this distance L3 is The distance L1 is the same as the distance L4 between the downstream end of the left side surface 23a of the third permanent magnet 23 and the right side surface 3b of the first permanent magnet 3 (note that this distance L4 is the distance L2). It is smaller than (L3 <L4). Therefore, as described in FIG. 4 above, the repulsive force in the space S3 between the upstream end of the left side surface 23a of the third permanent magnet 23 and the right side surface 3b of the first permanent magnet 3 is the third permanent. It is larger than the repulsive force in the space S4 between the downstream end of the left side surface 23a of the magnet 23 and the right side surface 3b of the first permanent magnet 3. As described above, the repulsive force in the space S3 (corresponding to the repulsive force 1 shown in FIG. 4) is larger than the repulsive force in the space S4 (corresponding to the repulsive force F2 shown in FIG. 4). A certain thrust P is generated. Therefore, similarly to the second permanent magnet 17, the third permanent magnet 23 and the first permanent magnet 3 generate a component force P, which is a thrust acting in the first direction indicated by the arrow A. That is, in the present embodiment, the moving body 5 moves in the direction of arrow A by the thrust P, which is a component force acting by the repulsive force between the second permanent magnet 17 and the like, the third permanent magnet 23 and the like, and the first permanent magnet 3. It is designed to do.

In the present embodiment, three second permanent magnets are provided, but the number of second permanent magnets may be singular or may be plural other than three. The same applies to the third permanent magnet. The number of the second permanent magnet and the third permanent magnet is preferably the same, but if the thrust P by the second permanent magnet and the thrust P by the third permanent magnet have the same strength. , These numbers may be different. For example, the number of third permanent magnets can be reduced compared to the second permanent magnet by using a magnet having a stronger magnetic force in the third permanent magnet than in the second permanent magnet.

As schematically shown in FIGS. 1A and 1B, the center line CL1 (second) passing through the center in the height direction of the second permanent magnet 17 and the like and the third permanent magnet 23 and the like along the first direction. Permanent magnet side center line), CL3 (third permanent magnet side center line), and center line CL2 (first permanent magnet side center line) that passes along the center in the height direction of the first permanent magnet 3 along the first direction. Consists of the same center line CL as. That is, as shown in FIG. 1A, the second permanent magnet 17 and the like are fixed to the left slide portion 7 so that the center line CL1 thereof coincides with the center line CL2 of the first permanent magnet 3. .. Similarly, the center line CL3 of the third permanent magnet 23 and the like is also fixed to the right slide portion 9 so that the center line CL3 coincides with the center line CL3 of the first permanent magnet 3. In other words, the thickness of the left slide portion 7 and the right slide portion 9 (width in the height direction in FIG. 1) is such that the center line CL1 of the second permanent magnet 17 and the like and the center line CL2 of the third permanent magnet 23 and the like are used. The thickness coincides with the center line CL2 of the first permanent magnet 3.

Here, the above-mentioned mobile body 5 can be summarized as follows. As described above, the second permanent magnet 17 and the like and the third permanent magnet 23 and the like are inclined to the lower left and lower right as seen in FIG. 2 on the left slide portion 7 and the right slide portion 9 of the moving body 5. It is fixed. As a result, in the set state shown in FIG. 1A, the second permanent magnet 17 and the like and the third permanent magnet 23 and the like maintain an inclined positional relationship in which the second permanent magnet 17 and the like are inclined at angles θ1 and θ2 with respect to the first permanent magnet 3. It is designed to do. Further, on the left slide portion 7 and the right slide portion 9 of the moving body 5, the second permanent magnet 17 and the like and the third permanent magnet 23 and the like are provided on the center lines CL1 and CL3 of these and the center line CL2 of the first permanent magnet 3. Is fixed to match. As a result, in the set state shown in FIG. 1 (a), as shown in FIG. 1 (b), the center lines CL1, CL2, and CL3 coincide with each other to form one center line CL1. Is designed to hold. That is, the left slide portion 7 and the right slide portion 9 of the moving body 5 have a fixing function (mounting function) for fixing the second permanent magnet 17 and the like and the third permanent magnet 23 and the like, and have the above-mentioned inclined positional relationship. And, it has a maintenance function for maintaining (holding) the above-mentioned center line coincidence state.

Further, the left and right standing portions 11, 13 and the connecting portion 15 of the moving body 5 are the distance between the second permanent magnet 17 and the like and the first permanent magnet 3 in the set state shown in FIG. 1 (a). The distance between the permanent magnet 23 and the like and the first permanent magnet 3 is kept constant. Therefore, the left and right standing portions 11, 13 and the connecting portion 15 have a regulating function of restricting the moving direction of the moving body 5 in the first direction indicated by the arrow A.

Next, the operation of the present embodiment will be described based on the above-described configuration. First, as shown in FIGS. 1A and 5A, the moving body 5 is lowered from above near the central portion of the first permanent magnet 3 and the first permanent magnet is placed in the internal space S1 of the moving body 5. The moving body 5 is arranged (set) with respect to the first permanent magnet 3 so that the 3 fits. At this time, as shown in FIG. 1B, the center line CL2 of the first permanent magnet 3 coincides with the center line CL1 of the second permanent magnet 17 and the center line CL3 of the third permanent magnet 23 and the like. Of the repulsive forces generated between the second permanent magnet 17 and the like and the third permanent magnet 23 and the like and the first permanent magnet, as seen in FIG. 1 (a), the vertical direction (vertically perpendicular to the first direction). The repulsive forces in the left and right directions (directions perpendicular to the left and right with respect to the first direction) are balanced. On the other hand, among the repulsive forces generated between the second permanent magnet 17 and the like, the third permanent magnet 23 and the like, and the first permanent magnet 3, the vertical direction (the first direction indicated by the arrow A) as seen in FIGS. 2 and 5. In the direction (in the direction along), as described above, the repulsive force on the upstream side is larger than that on the downstream side between the second permanent magnet 17 and the like, the third permanent magnet 23 and the like, and the first permanent magnet 3 ( Because it is strong), the thrust P acts in the first direction indicated by the arrow A (see FIG. 4). This thrust P causes the moving body 5 to move in the first direction indicated by the arrow A. The moving body 5 continues its movement as long as the first permanent magnet 3 is interposed in the internal space S of the moving body 5.

As described above, the left and right sliding portions 7 and 9 of the moving body 5 have the fixing function and the maintaining function, and the left and right standing portions 11 and 13 and the connecting portion 15 of the moving body 5 have the restricting function. Therefore, as long as the first permanent magnet 3 is interposed in the internal space S of the moving body 5, the thrust P is generated and the moving body 5 can be continued to move.

After that, as shown in FIG. 5B, the second permanent magnet 21 and the third permanent magnet 27 fixed to the moving body 5 continuing to move in the first direction are one end of the first permanent magnet 3. In the state of passing through the portion (the upper end portion as seen in FIG. 5), the repulsive force between the second permanent magnets 17 and 19 and the third permanent magnets 21 and 23 and the first permanent magnet 3 is working, while the second permanent magnet is working. Between the permanent magnet 21 and the third permanent magnet 27, the repulsive force against the first permanent magnet 3 does not work (the repulsive force becomes weaker). As a result, the resistance to the movement of the moving body 5 in the first direction disappears (because the resistance is reduced), so that the moving body 5 suddenly accelerates in the state shown in FIG. 5 (b). In other words, it can be said that the thrust generated by the thrust generation mechanism 1 is stronger in the state shown in FIG. 5 (b) than in the state shown in FIG. 5 (a).

As shown in FIG. 5C, the second permanent magnet 17 and the third permanent magnet 23 fixed to the moving body 5 are the other ends of the first permanent magnet 3 (the lower end as seen in FIG. 5). When the moving body 5 is moved by hand to the position where it comes out of the above, and the hand is released, between the second permanent magnets 19, 21 and the third permanent magnets 23, 25 and the first permanent magnet 3. While the repulsive force is working, the repulsive force against the first permanent magnet 3 does not work between the second permanent magnet 17 and the third permanent magnet 23, so the arrow B in the direction opposite to the first direction indicated by the arrow A It will move in the second direction indicated by. Even in the state of FIG. 5 (c), it can be said that the thrust is stronger than that of the state of FIG. 5 (a).

Further, in the present embodiment, the first permanent magnet 3 is fixed and the moving body 5 is movable, but instead of this, the moving body 5 is made movable without fixing the first permanent magnet 3 and the moving body 5 is flat. It may be a fixed portion fixed to G, and the first permanent magnet 3 may be moved with respect to the moving body 5 which is the fixed portion. In this case, the left and right slide portions 7 and 9 of the moving body 5 which became the fixed portion have the above-mentioned maintenance function, and the left and right standing portions 11 and 13 and the connecting portion of the moving body 5 which became the fixed portion. 15 has a regulating function of regulating the moving direction of the first permanent magnet 3 in the first direction. The same applies to the other embodiments described below.

Hereinafter, other embodiments will be described in sequence, but the description will be omitted or simplified by assigning the same reference numerals to the same components as described above.

FIG. 6 is a diagram schematically showing a thrust generation mechanism according to the second embodiment. In FIG. 6, the second permanent magnet 17 and the like and the second permanent magnet 23 are fixed to the moving body 5 shown in FIG. 1 and the like, but in FIG. 6, the moving body 5 is omitted and the second permanent magnet 23 is omitted. Only the fixed magnet 3 and the second permanent magnet 17 and the like and the second permanent magnet 23 are shown. The same applies to FIGS. 9 to 11 and the like described later.

As shown in FIG. 6, in this second embodiment, the plurality of first permanent magnets 3 form gaps K with each other along the first direction indicated by the arrow A (spaced from each other). By arranging a plurality of them, the distance between the second permanent magnet 17 and the like and the third permanent magnet 23 and the like and the first permanent magnet 3 is increased (in other words, for example, the right side surface of the second permanent magnet 17). It can be said that the distance between 17b and the left side surface 3a of the first permanent magnet 3 is increased), which is different from the first embodiment. The vertical distance of the gap K as seen in FIG. 6 is shorter than the distance between the upstream end and the downstream end of the second permanent magnet 17. In FIG. 6, of the plurality of gaps K, only one gap K is shown, and the other gaps K are omitted. A non-magnetic material connecting portion (not shown) for connecting the upper and lower first permanent magnets 3 is provided in the gap portion K to stabilize the positional relationship between the upper and lower first permanent magnets 3. You may.

In this second embodiment, in the state of FIG. 6A, the moving body 5 maintains the movement in the first direction indicated by the arrow A, as in the state shown in FIG. 5A. In this state, when the moving body 5 moves to the position shown in FIG. 6B, that is, when the second permanent magnet 21 and the third permanent magnet 27 fixed to the moving body 5 reach the position facing the gap K. As described with reference to FIG. 5 (b), the moving body 5 rapidly accelerates and moves toward the position shown in FIG. 6 (c) due to the generation of a stronger thrust than the state of FIG. 6 (a). .. After that, in the state of FIG. 6 (c), the moving body 5 maintains the movement in the first direction indicated by the arrow A, as in the case of FIG. 6 (a). Since a plurality of the gap portions K are provided in the first permanent magnet 3, the above-mentioned operations of FIGS. 6 (a) to 6 (c) are repeated.

By providing the gap portion K in this way, when the downstream side in the first direction of the moving body 5 reaches the position facing the gap portion K, a strong thrust P is generated and the moving body 5 can be rapidly accelerated. As a result, even if the momentum of the moving moving body 5 is weakened for some reason, a strong thrust P is generated by the gap portion K to assist the moving body 5 to move, and the moving body 5 can be assisted. The movement can be maintained more. The same applies to the case where a non-magnetic material connecting portion for connecting the upper and lower first permanent magnets 3 described above is provided instead of the gap portion K.

The gap portion K is not limited to that of FIG. 6 described above, and various forms can be adopted. For example, as shown in FIG. 7A, the gap formed by providing the first permanent magnet 3 with a small diameter portion whose diameter gradually decreases toward the moving direction may be the gap portion K. In this case, as shown in FIG. 7A, when the second permanent magnet 21 and the second permanent magnet 27 reach the positions facing the gap K, the second permanent magnet 21, the second permanent magnet 27, and the first permanent magnet are reached. The distance from the magnet 3 is increased, the repulsive force between the second permanent magnet 21 and the second permanent magnet 27 and the first permanent magnet 3 is weakened, and the resistance of the moving body 5 in the moving direction is reduced. A strong thrust P will be generated. As a result, the same effect as that of the second embodiment shown in FIG. 6 is obtained. Further, as shown in FIG. 7B, the gap formed by forming a plurality of slits in the first permanent magnet 3 may be the gap portion K, and in this case as well, the third shown in FIG. (Ii) It has the same effect as that of the embodiment.

Here, the gap portion K is provided as described above by reducing the repulsive force between the second permanent magnet 17 and the like and the third permanent magnet 23 and the like and the first permanent magnet 3 to generate a strong thrust P. This is to make it. As a method of reducing the repulsive force between the second permanent magnet 17 or the like and the third permanent magnet 23 or the like and the first permanent magnet 3, as described above, the second permanent magnet 17 or the like and the third permanent magnet 23 or the like In addition to the method of increasing the distance between the first permanent magnet 3 and the first permanent magnet 3, for example, a part of the right side surface 17b of the second permanent magnet 17 has a magnetic pole opposite to the left side surface 3a of the first permanent magnet 3. The repulsive force between them may be reduced by providing the magnets in.

Specifically, as shown in FIG. 8A, a fourth permanent magnet 31 is provided at the downstream end of the right side surface 17b of the second permanent magnet 17 by adhesion or the like. The right side surface 31b of the fourth permanent magnet 31 has an S pole which is the opposite magnetic pole to the left side surface 3a of the first permanent magnet 3 which is the north pole. Thereby, the repulsive force between the downstream end portion of the right side surface 17b of the second permanent magnet 17 and the left side surface 3a of the first permanent magnet 3 facing the downstream end portion can be reduced.

In addition to this shown in FIG. 8 (a), as shown in FIG. 8 (b), as the second permanent magnet, a magnet in which a plurality of disk-shaped small permanent magnets 32 are connected may be used, and the connected small permanent magnets may be used. One of the magnets may be a small permanent magnet 34 having the opposite polarity (the front and back of this small magnet are reversed from the front and back of the other small permanent magnets). The number of the small permanent magnets 34 having opposite polarities is not limited to one, and a plurality of small permanent magnets 34 having opposite polarities may be provided. For example, the small permanent magnets of reference numeral 32 and reference numeral 34 shown in FIG. 8B are provided. Small permanent magnets may be arranged alternately with each other. The shape of the second permanent magnet may be the one shown in FIGS. 8 (c) to 8 (e). Further, a magnet having the opposite polarity may be inserted into the gap K in FIG. 7B to fix the magnet. In this case, the white portion that was the void portion K in FIG. 7B becomes the north pole with respect to the black south pole.

Here, as described above, when the gap portion K is formed by reducing the diameter of the first permanent magnet 3, the distance between the second permanent magnet 17 and the second permanent magnet 23 and the first permanent magnet 3 becomes large. When the repulsive force is weakened and the extension portion is formed by increasing the diameter of the first permanent magnet 3, the distance between the second permanent magnet 17 and the second permanent magnet 23 and the first permanent magnet 3 is reduced, and the repulsive force is increased. It will be strengthened. By adjusting the diameter of the first permanent magnet 3 in this way, the repulsive force between the second permanent magnet 17 and the second permanent magnet 23 and the first permanent magnet 3 can be adjusted. As an example of the extension portion having a large diameter of the first permanent magnet 3, as shown in FIG. 7C, the side surfaces of the plurality of first permanent magnets may be joined to each other. The example shown in FIG. 7 (c) can be applied when it is desired to increase the diameter of the first permanent magnet 3 shown in FIG. 2 in the middle of the longitudinal direction. The above-mentioned gap portion K and extension portion may be provided in the second permanent magnet 17 or the like and the third permanent magnet 23 or the like. Further, in the example shown in FIG. 8, a part of the second permanent magnet 17 and the like and the third permanent magnet 23 and the like have opposite polarities, but this may be applied to the first permanent magnet 3. The point is that at least one of the first permanent magnet 3 and the second permanent magnet 17 and the like and the third permanent magnet 23 and the like is provided with at least one of a gap portion K, an extension portion, and opposite polarities. The repulsive force generated in the magnet should be adjustable.

FIG. 9 is a diagram schematically showing a thrust generation mechanism according to the third embodiment. In the third embodiment, in the first permanent magnet 3, the upper portion 3B has an S pole and the lower portion 3A has an N pole. Further, the second permanent magnet 17 is also different from the first embodiment in that the upper portion 17B has an S pole and the lower portion 17A has an N pole. In other words, in the thrust generation mechanism according to the third embodiment, the first permanent magnet 3 of the first embodiment shown in FIG. 2 is rotated 90 degrees to the left, and the second permanent magnet 17 and the like and the third permanent magnet are used. It can be said that each of the 23 mag is the same as the state in which it is rotated 90 degrees to the left.

Also in this third embodiment, the center line passing through the center in the height direction of the first permanent magnet 3 along the first direction and the center in the height direction of the second permanent magnet 17 and the like and the third permanent magnet 23 and the like. Consistent with the center line passing along the first direction, a single center line CL is formed. In this third embodiment, as shown in FIGS. 9 (b) and 9 (c), the center line of the first permanent magnet 3 is the boundary between the magnetic poles of the first permanent magnet 3 (between the north pole and the south pole). ), And the center lines of the second permanent magnet 17 and the like and the third permanent magnet 23 and the like are centered on the respective magnetic poles of the second permanent magnet 17 and the like and the third permanent magnet and the like 23. It is the center line that passes through. Further, in the third embodiment, the angle θ1 formed by the left side surface 3a of the first permanent magnet 3 and the right side surface 17b of the second permanent magnet 17 is 10 degrees or more and 45 degrees or less (10 degrees ≦ θ1 ≦ 45). It is preferable to keep it within the range of degree). This is because when the angle θ1 is less than 10 degrees, the difference between the distances L1 and L2 described above is small, so that the thrust P required to move the moving body 5 does not work. Further, if the angle θ1 exceeds 45 degrees, it becomes difficult to obtain the component force required to move the moving body 5 (if the angle θ1 is 90 degrees, the component force in the direction of arrow A does not work). ). The angle θ1 is more preferably 25 degrees or more and 35 degrees or less (25 degrees ≦ θ1 ≦ 35 degrees). Further, the angle θ2 formed by the right side surface 3b of the first permanent magnet 3 and the left side surface 23a of the third permanent magnet 23 is the same as the angle θ1. Even with this configuration, the same effects as in the first embodiment can be obtained.

In the fifth embodiment, the rail portion RL, which is a concave groove-shaped groove extending in the first direction, is formed on the plane G, and the lower end of the right standing portion 13 is formed without providing the right slide portion 9 of the first embodiment. The difference from the first embodiment is that the portion is extended downward and inserted into the rail portion RL. That is, in the fifth embodiment, the moving body 5 is moved by the repulsive force generated between the second permanent magnet 17 and the like and the first permanent magnet 3 without providing the third permanent magnet 23 and the like. There is. In the case of the fifth embodiment, in addition to the left and right standing portions 11, 13 and the connecting portion 15, the rail portion RL constitutes the moving direction regulating portion.

Further, as shown in FIG. 15, the number of the inner peripheral side second permanent magnets 17 is larger than the number of the outer peripheral side third permanent magnets 23. Also in this case, the moving body 5 (not shown in FIG. 15) rotates and moves in the first direction indicated by the arrow C. The number of the outer peripheral side third permanent magnets 23 and the number of the inner peripheral side second permanent magnets 17 may be the same number, or the number of the inner peripheral side second permanent magnets 23 may be larger than the number of the outer peripheral side third permanent magnets 23.

Further, in the present embodiment, similarly to the first embodiment, the first permanent magnets 61 and 63 are fixed to the plane G by their own weight, but instead of this, for example, the first permanent magnets A non-magnetic case containing 61 and 63 may be provided, and the case may be fixed to the flat surface G with a fixture such as a screw or adhesive. Further, in FIG. 19, for convenience of explanation, only the upstream first permanent magnet 61 and the downstream first permanent magnet 63 are shown, but depending on the specifications and the like, these upstream and downstream first permanent magnets are shown. A set of 61 and 63 may be used as one first permanent magnet portion, and a plurality of these first permanent magnet portions may be provided and sequentially connected in a straight line or sequentially in an annular shape. Needless to say.

As shown in FIG. 19, the moving body 70 has left and right standing portions 11 and 13 (the standing portion 13 is not shown in FIG. 19), a connecting portion 15, and wheels 5E and 5F. A left second permanent magnet 81 is fixed to the lower end of the left standing portion 11, a right second permanent magnet 83 is fixed to the lower end of the right standing portion 13, and a wheel 5E is fixed to the left second permanent magnet 81. Wheels 5F are attached to the magnet 43. Needless to say, a non-magnetic case in which the left and right second permanent magnets 81 and 83 are enclosed 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 different from the above-described first embodiment and the like in that they are arranged along the first direction indicated by the arrow A (parallel to the first direction). (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 that the left and right standing portions 11, 13 and the connecting portion 15 of the moving body 70 have a regulating function). 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 standing portions 11 and 13 so as to be perpendicular to the plane G and in the direction along the first moving direction (parallel to the first moving 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 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. (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 of the center line CL4 of the 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 thereof is located below the center line CL4.

Here, in the above-described embodiment, for example, as shown in FIG. 4, between the upstream end of the right side surface 17b of the second permanent magnet 17 and the left side surface 3a of the first permanent magnet 3 in the space S2. And the distance between the downstream end of the right side surface 17b of the second permanent magnet 17 in the space S3 and the left side surface 3a of the first permanent magnet 3 in the space S2. The repulsive force F1 was stronger than the repulsive force F2 in the space S3 (F1> F2), and a thrust P, which is a component force acting in the first direction indicated by the arrow A, was generated. In other words, in the above-described embodiment, the thrust is generated by changing the distance between the permanent magnets facing each other with the same poles so that the strength of the repulsive force is generated. On the other hand, the present embodiment is different from the above-described embodiment in that, in general, the repulsive force is increased or weakened by changing the overlapping range of the facing surfaces of the permanent magnets facing each other with the same poles. .. Next, this will be described.

First, as shown in FIGS. 20 (b) and 21 (a), when the upstream first permanent magnet 61 is placed on the plane G, the rightmost left second permanent magnet in FIG. 20 (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. 21 (a). Although it receives a repulsive force in the direction vertically away from, the right second permanent magnet 83 (not shown in FIGS. 20 and 21) 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 in the left-right direction as well.

Further, like the leftmost left second permanent magnet 81 in FIG. 20B, its center line CL5 is located above the center line CL4 of the upstream first permanent magnet 61. In this case, a repulsive force is received in the direction indicated by the arrow G in FIGS. 20 (b) and 21 (a) (diagonally upward to the right when viewed in FIG. 21 (a)), and the right second magnet on the opposite side of 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. 21A, 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. 20 (b), it is located at a lower position. Repulsive force is applied in the direction indicated by the arrow H in FIGS. 20 (b) and 21 (a) (diagonally downward to the right when viewed in FIG. 21 (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. 21A, 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 FIG. 21A, in a state where the upstream first permanent magnet 81 is placed on the plane G, the magnetic poles are separated between the left portion and the right portion (for example, shown in FIG. 1 and the like described above). Although the same example as the first permanent magnet 3 of the first embodiment) has been described, as shown in FIG. 21 (b), in a state where the upstream first permanent magnet 61 is placed on the plane G, the upper portion and the upper portion An example in which the upstream first permanent magnet 62 whose magnetic poles are separated from the lower portion and the left second permanent magnet 81 are the left second permanent magnet 82 whose magnetic poles are separated from the upper portion and the lower portion (for example, described above). In the same example as in the third embodiment shown in FIG. 9, the moving body 70 floats upward in the upper position, balances in the central position, and moves in the lower position, as in FIG. 21A. The body 70 will be pressed against the lower plane G.

Here, in the present embodiment, as shown in FIG. 19B, in the moving body 70, the center lines CL5 of the left and right second permanent magnets 81 and 83 are the upstream and downstream first permanent magnets 61. Since it is located at a position below the center line CL4 of 63, the moving body 70 is in a state of being pressed against the plane G as shown by the arrow H in FIG. 19, so that the moving body 70 is stably placed on the plane G. It will be in the state of being done.

Further, since the upstream first permanent magnet 61 is inclined upward to the left in FIG. 19B, the upstream first permanent magnet 61 is gradually upstream toward the upstream side (left side in FIG. 19). The space S5 formed between the bottom surface 61d of the first permanent magnet 61 and the plane G becomes large. Then, in a state where 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 two permanent magnets 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 decreases 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), and the repulsive force between these side surfaces 81b and 61a gradually weakens from the upstream side to the downstream side. Therefore, thrust acts in the direction of arrow A. Similarly, the left side surface 83a of the right side second permanent magnet 83 also has a smaller range facing the right side surface 61b of the upstream side first permanent magnet 61, and the repulsive force between these side surfaces 83a and 61b also decreases from the upstream side to the downstream side. Since it gradually becomes weaker toward the direction of arrow A, thrust acts in the direction of arrow A. As a result, the moving body 70 to which the left and right second permanent magnets 81 and 83 are fixed moves in the first direction indicated by the arrow A.

Further, as shown in FIG. 19A, 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. Since it is longer than the distance to the downstream side portion (square pillar-shaped portion) of the magnet, the repulsive force acting on this portion is further weakened, so that the thrust in the first direction indicated by the arrow A is further exerted. Therefore, when the moving body 70 is lowered and set from above the upstream end of the upstream first permanent magnet 61, the moving body 70 is indicated by an arrow A as shown in FIGS. 22 (a) to 22 (c). The movement in the first direction will be continued.

In this way, the movement of the moving body 70 can be continued with a simple configuration in which the first permanent magnets 81 and 83 on the upstream side and the downstream side are tilted. Further, by adjusting the inclination angles of the upstream and downstream first permanent magnets 81 and 83, the momentum of movement of the moving body 70 and the like can be adjusted. Here, if only the upstream first permanent magnet 61 is used, it will be inclined upward as it goes toward the downstream side. Therefore, if the length of the upstream first permanent magnet 61 is too long, the moving body The entire side surfaces 81b, 81a of the left and right second permanent magnets 81, 83 of 70 face the space S5, and the side surfaces 81b, 83a and the side surfaces 61a, 61b of the upstream first permanent magnet 61 Since the face-to-face state is released, the thrust in the first direction indicated by the arrow A does not work. As a result, the moving distance of the moving body 70 becomes short. On the other hand, in the present embodiment, as shown in FIG. 19, by connecting the upstream first permanent magnet 61 and the downstream first permanent magnet 63 as described above, the upstream first permanent magnet 61 The moving distance can be extended as compared with the case of a single unit. Further, when a set of these upstream and downstream first permanent magnets 61 and 63 is used as one first permanent magnet portion and a plurality of these first permanent magnet portions are provided and sequentially connected, the movement is performed. As long as the first permanent magnet portion is interposed between the left and right second permanent magnets 81 and 83 fixed to the body 70, the moving body 70 can continue to move. In other words, the moving distance of the moving body 70 can be adjusted by the number of connected first permanent magnet portions.

Is a side view schematically showing the thrust generation mechanism according to the eleventh embodiment. The thrust generation mechanism in the eleventh embodiment has a pair of plate-shaped first permanent magnets 64 and 64 and a moving body 70, and the pair of first permanent magnets 64 and 64 are connected to each other. They are facing each other, their upstream ends are close to each other, and their downstream ends are separated from each other. Specifically, with the downstream ends of the pair of first permanent magnets 64 and 64 separated by a predetermined distance, the upstream ends of the pair of first permanent magnets 64 and 64 are bonded to each other. By connecting with the above, the first permanent magnet portions 65 having an arrow shape are formed as a whole, and these first permanent magnet portions 65 are connected to each other. In FIG. 23, the moving body 70 is schematically drawn, and the left and right second permanent magnets 81 and 83 fixed to the moving body 70 are not shown.

That is, as shown in FIG. 23 (a), the upstream end of the central first permanent magnet portion 65 is located in the downstream end of the rightmost first permanent magnet portion 65 in FIG. 23 (a). These first permanent magnet portions 65 are connected so as to be slightly inserted. Further, as shown in FIG. 23 (b), a pair of first permanent magnets 64, 64 (hereinafter, referred to as right first permanent magnets 64, 64) constituting the rightmost first permanent magnet 65 and the center. The pair of first permanent magnet portions 64, 64 (hereinafter referred to as central first permanent magnets 64, 64) constituting the first permanent magnet portion 65 of the above is the first on the right side, as in the tenth embodiment described above. The downstream end of the lower parts of the permanent magnets 64, 64 and the upstream end of the upper part of the central first permanent magnet are connected by adhesion or the like, and the left and right second permanent magnets are fixed to the moving body 70. The relationship between the center lines CL5 of 81 and 83 and the center lines CL4 of these first permanent magnets 64 and 64 is the same as that of the tenth embodiment described above with reference to FIG. 20 (a). It has become. The relationship between the leftmost first permanent magnet portion 65 and the central first permanent magnet portion 65 in FIG. 23 is also the same as the relationship between the rightmost first permanent magnet portion 65 and the central first permanent magnet portion 65 described above. Needless to say,

Also in this eleventh embodiment, as shown in FIG. 23, the moving body 70 moves in the first direction indicated by the arrow A and is between the left and right second permanent magnets 81 and 83 fixed to the moving body 70. In addition, as long as the first permanent magnet portion 65 is interposed, the movement is maintained. Further, in the eleventh embodiment, as described above, the upstream end of the central first permanent magnet portion 65 is slightly inserted into the downstream end of the right first permanent magnet portion 65. Since these first permanent magnet portions 65 are connected to each other, the inner surface of each of the downstream end portions of the right first permanent magnet 65 and the outer surface of each of the upstream end portions of the central first permanent magnet 65. Will face each other with magnetic poles of opposite polarities. As a result, in this portion, the repulsive force between the left and right second permanent magnets 81 and 83 fixed to the moving body 70 is further weakened, so that the moving body 70 located in this portion is smoothly moved. be able to.

FIG. 24 is a plan view schematically showing the thrust generation mechanism according to the twelfth embodiment. The thrust generating mechanism of the twelfth embodiment includes a rotating shaft R rotatably supported by a bearing or the like (not shown), four support portions SJ1 extending in the horizontal direction from the rotating shaft R, and the support portion SJI. Each of them has four fixed moving bodies 70 and an annular first permanent magnet portion 66 in which the first permanent magnet portions 65 described in the eleventh embodiment described above are connected in an annular shape. Although the moving body 70 of the present embodiment is simply drawn in a straight line in FIG. 24, in reality, the entire moving body 70 of the tenth embodiment is viewed in a plan view as an annular ring. (1) The permanent magnet portion 66 is curved in an arc shape (the left and right second permanent magnets 81 and 83 of the moving body 70 are also curved in an arc shape), which is different from the eleventh embodiment.

Further, in each of the first permanent magnet portions 65 constituting the annular first permanent magnet portion 66, the rotation locus EK of the moving body 70 centered on the rotation axis R (although it is a virtual line in FIG. 24). It is arranged along the solid line). The rotation locus EK has a circular shape centered on the rotation axis R, and passes through the center of the moving body 70 in the left-right direction. Further, the first permanent magnet portion 65 is located between the upstream end portions of the pair of first permanent magnets 64, 64 constituting the first permanent magnet portion 65, and the downstream side of the pair of first permanent magnets 64, 64. The center between the ends is arranged so that the rotation locus EK passes through the center. By setting the moving body 70 so that the first permanent magnets 81 and 83 fixed to the moving body 70 are located on both sides of the annular first permanent magnet portion 65, the moving body 70 is indicated by an arrow D. Keep moving in one direction.

The side surface of the annular first permanent magnet 66 is the same as in FIG. 23 (b). Further, the downstream end of the first permanent magnet portion 65 is separated, but conversely, the upstream end may be separated and the downstream ends may be brought close to each other. The point is that the repulsive force between the left and right second permanent magnets 81 and 83 can be appropriately adjusted by adjusting the opening angle and orientation of the first permanent magnet portion 65.

FIG. 25 is a diagram schematically showing a thrust generation mechanism according to the thirteenth embodiment, and FIG. 25 (a) is a plan view schematically showing a thrust generation mechanism according to the thirteenth embodiment, (b). Is a side view schematically showing the thrust generation mechanism according to the thirteenth embodiment. In the eleventh embodiment, a central plate permanent magnet CB, which is a horizontally extending plate-shaped permanent magnet, an upper first permanent magnet 67 inclined upward to the right above the central plate permanent magnet CB, and a center. A lower first permanent magnet 68 inclined downward to the left is provided below the plate permanent magnet CB. The upstream end of the upper first permanent magnet 67 and the upstream end of the lower first permanent magnet 68 are connected to the central plate permanent magnet CB with their bottom surfaces close to each other by adhesion or the like. (1) The downstream end of the permanent magnet 67 and the downstream end of the lower first permanent magnet 68 are separated from each other. As a result, the spaces between the central plate permanent magnet CB and the upper first permanent magnet 67, and the spaces S6 and S7 that gradually increase toward the downstream side in the central plate permanent magnet CB and the lower first permanent magnet 68, respectively. Will be formed.

Further, in FIG. 25, the downstream end portion of the lower portion of the upper first permanent magnet 67 on the right side and the upstream end portion of the upper portion of the upper first permanent magnet 67 on the left side are connected by adhesion or the like, and the lower end portion on the right side is connected. The downstream end of the upper part of the one permanent magnet 68 and the upstream end of the lower part of the lower first permanent magnet 68 on the left side are connected by adhesion or the like. The center lines CL5 of the left and right second permanent magnets 81 and 83 of the moving body 70 are interposed between the center lines CL4 and CL4 of the upper first permanent magnet 67 and the lower first permanent magnet 68, respectively. ing.

Further, as shown in FIG. 25A, the upper first permanent magnet 67 has a tapered shape in which the diameter gradually decreases toward the upstream side in a plan view. Although not shown, the lower first permanent magnet 68 also has the same shape as the upper first permanent magnet 67. In FIG. 25, only the left and right second permanent magnets 81 fixed to the moving body 70 are shown, and the other components of the moving body 70 are not shown. Needless to say, the facing surfaces of the second permanent magnets 81 and 83 and the upper and lower first permanent magnets 67 and 68 in the present embodiment have the same polarity.

In the present embodiment, a repulsive force acts diagonally downward to the left indicated by the arrow H1 in the space S6 between the upper part of the left second permanent magnet 81 and the upper first permanent magnet 67, and the lower part of the left second permanent magnet 81. Since the repulsive force acts on the space S7 between the lower first permanent magnet 68 and the lower left permanent magnet 68 diagonally upward to the left indicated by the arrow H2, the left second permanent magnet 81 is stably positioned between them and is also positioned. The upper and lower facing surfaces of the second permanent magnet 81 with the first permanent magnets 67 and 68 gradually increase in the range facing the spaces S6 and S7 from the upstream side to the downstream side. Thrust is generated in one direction. The same applies to the right second permanent magnet 83. As a result, the moving body 70 to which the left and right second permanent magnets 81 and 83 are fixed moves in the first direction indicated by the arrow A. In the present embodiment, the repulsive force between the left and right second permanent magnets 81 and 83 is adjusted by providing the central plate permanent magnet CB, but the configuration is such that the central plate permanent magnet CB is not provided. Is also good.

Here, in the tenth to thirteenth embodiments described above, the thrust in the first direction indicated by the arrow A is obtained by inclining the first permanent magnet 61 and the like to form the space S5 and the like. However, instead of this, the first permanent magnet shown in FIGS. 26 and 27 may be used. 26 and 27 are side views showing the first permanent magnet according to the modified example.

The first permanent magnet 91 shown in FIG. 26 (a) has a space similar to that of the thirteenth embodiment shown in FIG. 25 by forming triangular columnar through holes penetrating both side surfaces of the square pillar-shaped permanent magnet. It forms S6 and S7. In addition, in FIG. 26 and FIG. 27, the black portion shows the S pole of the first permanent magnet according to each modification. In the example of FIG. 26A, triangular spaces S6 are arranged side by side in the upper portion of the first permanent magnet 91 and the respective spaces S6 are formed to be continuous, and the lower portion is also formed. Triangular spaces S7 with the spaces S6 turned upside down in a side view are arranged side by side, and each space S7 is formed to be continuous. Further, these spaces S6 and S7 are located at the same positions in the vertical direction as seen in FIG. 26, respectively. By interposing the left second permanent magnet 81 (right second permanent magnet 83) between these spaces S6 and S7, the thrust in the first direction indicated by the arrow A can be obtained, and the moving body 70 (not shown). Will move in the direction of arrow A.

In the first permanent magnet 92 shown in FIG. 26 (b), the spaces S6 and S7 in the upper portion of the first permanent magnet 92 are in a positional relationship in which the positions in the vertical direction are deviated from each other as seen in FIG. 26. It is different from the above-mentioned first permanent magnet 91. Further, the first permanent magnet 94 shown in FIG. 27A is an example in which a triangular columnar through hole is formed in a lower portion of a square columnar permanent magnet to form a space S6. Further, in the first permanent magnet 95 shown in FIG. 27B, the left and right spaces S6, S6, and S6 of the upper portion thereof are closed spaces independent of each other, and the left and right spaces S7, S7, and S7 of the lower portion thereof are also formed. It differs from the first permanent magnet 91 shown in FIG. 26A in that it is a closed space independent of each other. Further, the first permanent magnet 95 shown in FIG. 27 (c) is provided with permanent magnets 97 and 97 separate from the first permanent magnet 95 at the downstream end portions in the space S6 and the space S7. It is different from the first permanent magnet 94 in FIG. 27 (b). The permanent magnets 97 and 97 are arranged so that the left portion is the south pole and the right portion is the north pole in FIG. 27, respectively. Since the north pole of this right part has the opposite polarity to the south pole of the facing surface of the left second permanent magnet 81, attractive forces are generated from each other, so that the repulsive force between them becomes weak (in other words). Therefore, it can be said that FIG. 27 (c) is an example in which a magnet having the opposite polarity to the facing surface of the second permanent magnet is provided in the space S6). As a result, in the space S6, the repulsive force on the downstream side is further weakened than on the upstream side, and a stronger thrust in the first direction indicated by the arrow A can be obtained.

FIG. 28 is a diagram schematically showing a thrust generation mechanism according to the fourteenth embodiment, FIG. 28A is a side view of the thrust generation mechanism according to the fourteenth embodiment, and FIG. 28B is a side view of the thrust generation mechanism according to the fourteenth embodiment. It is a top view of the thrust generation mechanism which concerns on embodiment. The first permanent magnet 98 of the fourteenth embodiment is an annular permanent magnet having an outer portion having an S pole and an inner portion having an N pole magnetic pole, and the upper portion thereof has a shape similar to that of the space S7. It has a notched shape. On the outer peripheral side of the first permanent magnet 98, a rotating shaft R rotatably supported by a bearing or the like (not shown), a support portion SJ1 extending in the horizontal direction from the rotating shaft R, and the support portion SJ1 are fixed. A second permanent magnet 83 is arranged (in the present embodiment, the rotating shaft R and the support member SJ1 form a moving body). Further, the second permanent magnet 83 is fixed to the support portion SJ1 so that the center line L4 of the second permanent magnet 83 and the center line CL4 of the first permanent magnet 98 coincide with each other. With this configuration, the second permanent magnet 83 obtains thrust in the first direction indicated by the arrow D, and the second permanent magnet 83 swirls around the first permanent magnet 98 (along the circumference). Will move).

FIG. 29 is a diagram schematically showing a thrust generation mechanism according to the fifteenth embodiment. The thrust generating mechanism of the fifteenth embodiment generally includes a rotating shaft R, a support portion SJ1 extending in the horizontal direction from the upper end of the rotating shaft R, and a hanging portion SJ2 hanging downward from the tip of the support body SJ1. (In the present embodiment, these rotating shafts R, the support portion SJ1, and the hanging SJ2 form a moving body), the second permanent magnet 83 fixed to the inner surface of the hanging SJ2, and FIG. 26 ( It has a first permanent magnet 99 formed by forming the first permanent magnet 98 shown in a) in an annular shape.

Further, the first permanent magnet 99 is fixed to the upper end of the cylindrical support member TK2 fixed to the structure TK1 in a state of being inserted into the through hole formed in the structure TK1. The rotary shaft R is inserted through the cylindrical support member TK2 and is rotatably supported by a bearing or the like (not shown). With this configuration, the second permanent magnet 83 obtains thrust in the first direction indicated by the arrow D, and the second permanent magnet 83 swivels around the first permanent magnet 98.

The present invention is not limited to each of the above-described embodiments, and appropriate modifications can be made without departing from the gist thereof.
For example, in the tenth to thirteenth embodiments, the moving bodies 5 shown in FIGS. 1, 11 and the like are applied instead of the moving bodies 70 of these embodiments, and the same magnetic poles facing each other are applied. The first to ninth embodiments in which the thrust is obtained by changing the distance between the facing surfaces of the above, and the tenth to thirteenth embodiments in which the thrust is obtained by changing the facing range of the facing surfaces having the same polarity facing each other. Can be combined as appropriate.

Further, instead of the first permanent magnet 98 of the twelfth embodiment and the permanent magnet 99 of the thirteenth embodiment, the annular first permanent magnet portion 66 shown in FIG. 24, the upstream side and the downstream side of the tenth embodiment The first permanent magnets 61 and 63 are connected in an annular shape, the first permanent magnet portion 65 of the eleventh embodiment is connected in an annular shape, or the first permanent magnets of FIGS. 25 to 27 are annularly connected. It is also possible to apply the one concatenated with.

It can be said that it has a maintenance function for maintaining the positional relationship, and that the left and right standing portions 11, 13 and the connecting portion 15 of the moving body 70 have a regulating function). 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 standing portions 11 and 13 so as to be perpendicular to the plane G and in the direction along the first moving direction (parallel to the first moving 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 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. (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 of the center line CL4 of the 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 thereof 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. In contrast, in this embodiment, generally, in that by changing the overlapping range of the respective opposing surfaces of the permanent magnets facing the same poles differs from the embodiments described above. 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 in the left-right direction as well.

Further, like the leftmost left second permanent magnet 81 in FIG. 6B, its center line CL5 is located above the center line CL4 of the upstream first permanent magnet 61. In this case, a repulsive force is received in the direction indicated by the arrow G in FIGS. 6 (b) and 7 (a) (diagonally upward to the right when viewed in FIG. 7 (a)), and the right second magnet on the opposite side of 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.

In the present embodiment, as shown in FIG. 5 (b), the mobile 70, the left and right of the center line CL5 of the second permanent magnets 81 and 83, upstream and downstream first permanent magnet 61, Since it is located at a position below the center line CL4 of 63, the moving body 70 is in a state of being pressed against the plane G as shown by the arrow H in FIG. 5, so that the moving body 70 is stably placed on the plane G. It will be in the state of being done.

Further, since the upstream first permanent magnet 61 is inclined upward to the left in FIG. 5 (b), the upstream first permanent magnet 61 is gradually upstream toward the upstream side (left side in FIG. 5). The space S5 formed between the bottom surface 61d of the first permanent magnet 61 and the plane G becomes large. Then, in a state where 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 two permanent magnets 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, the moving body 70 to which the left and right second permanent magnets 81 and 83 are fixed 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 prism-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 to the downstream part (square prism-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 indicated by an arrow A as shown in FIGS. 8 (b) to 8 (c). Move in one direction. In the present specification, when the moving body 70 is moved, the upstream first permanent magnet 61 of FIG. 5, the upstream first permanent magnets of FIGS. 8 (a), 8 (b) and (c) are used. With regard to 61, it shall be treated as if it does not exist.

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.
