  A traveling body provided with magnetism such as a magnet (permanent magnet) is accommodated in a tubular container around which a coil is wound, and the magnetic traveling body is moved at a high speed along the longitudinal direction of the container. 2. Description of the Related Art An electromagnetic generator that utilizes a phenomenon in which a current is generated in a coil by reciprocating (vibrating) in the past has been known. Since the generated current can be sent to a lighting device (lighting device) via a lighting circuit connected to the coil, this type of electromagnetic generator is provided with a lighting device, for example, at night running It is used as a portable lighting device to ensure safety during exercise. Alternatively, there is an attempt to generate electricity by floating the electromagnetic generator having the above-described configuration on the sea surface and reciprocating the magnetic traveling body using wave motions on the sea surface.

  FIG. 1 shows a configuration example of a portable lighting device that has been conventionally used. 1 includes a long cylindrical container (tubular container) 10, a magnet (permanent magnet) 11 accommodated inside the long cylindrical container, and an outer periphery of the long cylindrical container 10. The coil 12 is wound, and the lighting circuit 13 includes a lighting device connected to the coil 12. For example, when the runner fixes the portable lighting device having such a configuration to the arm portion and performs running, the inside of the cylindrical container 10 of the portable lighting device according to the swing (swing) of the arm portion during running Since the magnet 11 reciprocates along the cylindrical container in the container 10 (the direction of movement is indicated by an arrow in FIG. 1), a current is generated in the coil 12 by the reciprocating movement of the magnet 11. To do. And this electric current is supplied to the lighting circuit 13 connected to the coil 12, and the lighting fixture (illuminating fixture) with which the lighting circuit was equipped lights up. The generation of current generated in the coil 12 is usually intermittent, so that the lighting is also intermittent, but the continuous lighting is also possible by connecting a storage battery to the lighting circuit 13.

  Patent Document 1 discloses an electromagnetic generator that has the same basic configuration as that shown in FIG. 1 but has a configuration that is easy to manufacture and has improved power generation efficiency. That is, in the electromagnetic generator disclosed in Patent Document 1, in order to increase the power generation efficiency, the magnet accommodated in the long cylindrical container is composed of a plurality of magnets that are not coupled to each other, and the magnetic poles of adjacent magnets By arranging the magnets so that their directions are magnetically opposite, that is, the N poles or S poles of adjacent magnets are opposed to each other, the adjacent magnets swing while being suspended in a repulsive state. ing.

  Patent Document 2 also discloses an electromagnetic generator having the same basic configuration as that of FIG. 1 but with higher power generation efficiency. That is, the electromagnetic generator disclosed in Patent Document 2 is also a combination of a plurality of magnets that are separated from each other in order to increase the power generation efficiency, and the magnetic poles of the magnets. The arrangement is such that the directions are magnetically opposite, that is, the N poles or S poles of adjacent magnets face each other.

  Patent Document 3 also discloses an electromagnetic generator having the same basic configuration as that of FIG. 1 but with higher power generation efficiency. That is, the electromagnetic generator disclosed in Patent Document 3 also has a magnet assembly in which a plurality of magnets housed in a long cylindrical container are separated from each other in order to increase power generation efficiency, and the magnetic poles of the magnets A configuration in which the directions are magnetically opposite, that is, a configuration in which the N poles or S poles of adjacent magnets are opposed to each other, and a configuration in which a plurality of coils are wound around the outer periphery of the cylindrical container Has been.

  In Patent Document 4, as a general-purpose electromagnetic generator with good power generation efficiency, a coil is wound along the inner periphery of a long cylindrical container, and a magnet is supported by a pair of elastic supports (coil springs). An electromagnetic generator is disclosed.

  In Patent Document 5, in order to reduce the friction between the long cylindrical container and the magnet, the magnet is accommodated and fixed in a small-diameter long cylindrical container and then accommodated in the long cylindrical container. A vibrating electromagnetic generator that vibrates in this manner is disclosed.

  The traveling body that travels in the pipe is also used as a weight of a gravity center moving lure. That is, Patent Document 6 discloses a center-of-gravity movement type lure having a configuration in which a tubular space is provided inside a lure body and a weight formed as a sphere moves (runs) in the tubular space. The weight accommodated in the tubular space moves back and forth in the tubular space due to the lure throwing operation by the angler, the fishing rod operation by the angler after the lure is thrown into the water, and the influence of waves. For this reason, the center-of-gravity moving lure contributes to extending the throwing distance of the lure. Furthermore, the movement of the weight in the tubular space of the lure thrown into the water will show the same behavior as a small fish swimming, so the effectiveness as a lure for fishing fish is enhanced.

  Furthermore, a combination of a long guide rail having a shape similar to that of a tubular container and a moving rail capable of moving in the length direction inside the guide rail, the front and rear of the tool mounted on the moving rail A slide rail system (slide unit) that realizes smooth movement is also used in various applications such as a desk drawer support and a cabinet drawer support. For example, Patent Document 7 discloses an improved structure of a slide rail having a slit-like opening in the length direction and a combination of a square-shaped guide rail and a plate-like moving rail. In this improved structure of the slide unit, the moving rail can be smoothly moved with respect to the guide rail, and the moving rail can be securely fixed to the guide rail by a simple operation when necessary.

  The conventional electromagnetic generator shown in FIG. 1 generates a considerable amount of friction between a long cylindrical container (tubular container) and a magnet (movable magnet) as described in Patent Document 5. The power generation efficiency does not always reach a satisfactory level. In addition, friction with the inner surface of the long cylindrical container that occurs during repeated reciprocating movement of the magnet easily causes wear on the magnet surface and inner surface of the cylindrical container, and noise is also generated by the above friction. There is a problem that it is easy to do.

  On the other hand, a configuration disclosed in Patent Document 5, that is, a configuration in which a plurality of magnets are accommodated in a small-diameter tubular container and a small-diameter tubular container (inner container) containing the magnets is accommodated in an outer container. Even in this case, since friction is generated between the inner container and the outer container when the inner container is reciprocated, problems similar to those of the conventional electromagnetic generator having the configuration shown in FIG. 1 are likely to occur. In addition, since a plurality of magnets are accommodated in the inner container, it is necessary to use a tubular container having a large diameter as the outer container, which causes a problem that the size of the electromagnetic generator is increased.

  Next, the center-of-gravity movement type lure disclosed in Patent Document 6 will be described. In this center-of-gravity movement type lure, as described above, a spherical weight moves (runs) in the tubular inner space. Is not sufficiently sensitive to rotational movement in response to fluctuations in the posture of the lure.Therefore, especially when the lure is thrown into the water, the angler operates the fishing rod and moves back and forth in the tubular space due to the effects of waves. There is a problem that it is difficult to perform smoothly.

  In addition, the slide rail system disclosed in Patent Document 7, which is a combination of a long guide rail and a plate-shaped moving rail, is used as a desk drawer support or cabinet drawer support. As described above, there is no particular problem when the plate-shaped moving rail is used in a vertical position where the width direction is vertical. However, when the slide rails are arranged vertically, that is, when the guide rails and the plate-like moving rails are used in an upright position, the strength of the plate-like moving rails in the direction of the wide plate surface is insufficient. Therefore, there is a problem that deformation is likely to occur.

  The inventor of the present invention makes smooth power generation by reciprocating an in-pipe running body having a desired function such as a magnet and a weight inside a tubular container, such as the above-described electromagnetic generator and center-of-gravity-type lure.
