The cross-sectional view of Fig. 14 shows the lace end connecting part 300 cut along the F14-F14 cross section in Fig. 12. Fig. 15 is a cross-sectional view of the lace end connecting part 300 showing how the ends 575, 585 of the shoelace 500 are connected in the lace end connecting part 300.

[0035] The string end connecting part 300 includes a cylindrical portion 310 , a hole end portion 312 , a middle hole portion 314 , a hole end portion 316 , a mounting surface 320 , and a magnet 330 .

[0036] The cylindrical portion 310 of the string end connecting part 300 is a cylindrical portion. Inside the cylindrical portion 310, a series of through holes are formed: hole end portion 312, intermediate hole portion 314, and hole end portion 316. Hole end portion 312 is a part of the through hole that opens on the right side surface of the cylindrical portion 310.

The diameter of intermediate hole portion 314 is slightly smaller than the diameters of hole end portions 312 and 316. Hole end portion 316 is a part of the through hole that opens on the left side surface of the cylindrical portion 310.

[0037] When connecting the ends 575, 585 of the shoelace 500, the user threads the pull-out portion 570 of the shoelace 500 from the hole end 316 to the hole end 312, and threads the pull-out portion 580 of the shoelace 500 from the hole end 312 to the hole end 316. The user then ties a knot in the end 575 of the pull-out portion 570 that has been pulled out from the hole end 312, and also ties a knot in the end 585 of the pull-out portion 580 that has been pulled out from the hole end 316. The user then pulls the pull-out portions 570, 580 of the shoelace 500 simultaneously in the pulling-out direction, thereby connecting the ends 575, 585 of the shoelace 500 in the lace end connecting part 300 as shown in FIG. 15 .

[0038] The attachment surface 320 of the string end connecting part 300 is provided at the center of the bottom surface of the cylindrical portion 310. The attachment surface 320 is a flat surface that is slightly smaller than the attachment surface 156 of the housing part 110. A magnet 330 is provided inside the attachment surface 320. The magnet 330 is a permanent magnet in the shape of a rectangular plate. The magnet 330 has a magnetic force that attracts it to the magnet 150 of the main body part 100.

[0039] 16 is an explanatory diagram showing how the string end connecting part 300 is attached to the main body part 100. When attaching the string end connecting part 300 to the main body part 100, the user brings the attachment surface 320 of the string end connecting part 300 close to the attachment surface 156 of the main body part 100. This allows the string end connecting part 300 to be attached to the main body part 100 by the magnetic force that attracts the magnet 150 of the main body part 100 and the magnet 330 of the string end connecting part 300. The user can remove the string end connecting part 300 from the main body part 100 by pulling the string end connecting part 300 away from the main body part 100 with a force stronger than the magnetic force that attracts the magnet 150 and the magnet 330.

[0040] According to the shoelace fastener 10 described above, the main body part 100 can be held to the shoe 800 via the connecting string 200 that passes through the left and right lace holes 810, 820 of the shoe 800. This allows the shoelace fastener 10 to be used without providing a special structure to the upper of the shoe 800.

[0041] Furthermore, according to the shoelace fastener 10, the lace end connecting part 300 is configured to be detachable from the main body part 100, so that the pair of ends 575, 585 of the shoelace 500 can be held relative to the main body part.

[0042] The technology disclosed in this specification is not limited to the above-described embodiments, examples, and modifications. The technology disclosed in this specification can be realized in various configurations without departing from the spirit thereof. Among the technical features in the above-described embodiments, examples, and modifications, those corresponding to the technical features in each form described in the Summary of the Invention section can be replaced or combined to solve some or all of the above-described problems or to achieve some or all of the above-described effects. Furthermore, technical features not described as essential in this specification can be deleted as necessary.

[0043] For example, the shoelace fastener 10 does not need to have a configuration that allows the lace end connecting part 300 to be detachably attached to the main body part 100. In this case, the slide portion 122 of the slide component 120 may be similarly provided not only on the top surface of the main body part 100 but also on the bottom surface.

[0044] Fig. 17 is an explanatory diagram showing another embodiment of a lace end connecting part 300B. In the above-described embodiment, the shoelace fastener 10 may be equipped with the lace end connecting part 300B shown in Fig. 17 instead of the lace end connecting part 300. The lace end connecting part 300B connects the end 575 of the pull-out portion 570 and the end 585 of the pull-out portion 580 by forming a knot on the outside.

[0045] Figure 18 is a bottom view showing a main body part 100 of another embodiment. The main body part 100 of Figure 18 is similar to the main body part 100 of Figure 6 except that it has a protrusion 152C instead of the protrusion 152 and does not have the protrusion 154. The protrusion 152C has a shape that is wider than the protrusion 152 by the amount that the protrusion 154 has been removed. In the main body part 100 of Figure 18, the string end connecting part 300 is held between the protrusion 152C and the cover part 130. [Explanation of symbols]
