Further, the first plate portion 13 is formed with a string insertion hole H1 that penetrates the base body portion 11 in the Z direction. The string insertion holes H1 are arranged so as to be lined up in the X direction with respect to the base side edge 131. The cross-sectional shape of the string insertion hole H1 is, for example, rectangular. The Y-direction dimension of the string insertion hole H1 is approximately the same as the Y-direction dimension of the base side edge 131. Further, it is preferable that the Y-direction dimension of the string insertion hole H1 is equal to or larger than the width of the string S, and the X-direction dimension of the string insertion hole H1 is equal to or larger than the thickness of the string S.

The second plate portion 14 is disposed on one side in the Y direction (−Y direction side) with respect to the base side edge portion 131, and protrudes from the first plate portion 13 in the −X direction. This second plate portion 14 is formed with an engagement hole H2 that penetrates the base body portion 11 in the Z direction. Although the cross-sectional shape of the engagement hole H2 is not particularly limited, it is preferably approximately equal to the cross-sectional shape of the column portion 31 described later.

The base protruding portion 15 protrudes from the base body portion 11 along the base side edge portion 131 in the −Z direction. The base protruding portion 15 has a portion that is continuous with the base side edge portion 131 and faces in the −X direction. It is preferable that the cross-sectional shape of the base convex strip 15 perpendicular to the extending direction has an arcuate shape protruding in the -Z direction. The protrusion height of the base protruding portion 15 is not particularly limited, but is, for example, more than half and less than one time the thickness of the base body portion 11 in the Z direction.

The arm portion 20 includes an arm main body portion 21 and an arm protruding portion 27 that protrudes from the arm main body portion 21 in the +Z direction.
The arm main body 21 has a proximal end 22 connected to the base 10 and a distal end 23 that is a free end of the arm 20. Further, the arm body portion 21 extends from the base portion 10 along a plane perpendicular to the Z direction. This arm body portion 21 includes a front surface portion 24A facing the +Z direction and a back surface portion 24B facing the −Z direction. Further, the arm main body 21 of this embodiment is formed into a plate shape with the same thickness as the base main body 11, and the base main body 11 and the arm main body 21 are arranged at the same position in the Z direction. .

The base end portion 22 of the arm body portion 21 is connected to the other side of the base body portion 11 in the Y direction (+Y direction side) with respect to the base side edge portion 131, and protrudes from the base body portion 11 in the −X direction. - It is curved towards the Y direction. Further, an arc-shaped relief portion 25 is formed between the base end portion 22 and the base body portion 11.

The main extending direction of the arm main body portion 21 is inclined with respect to the X direction and the Y direction so that the further it goes in the -Y direction, the more it is located in the -X direction. Further, the arm main body portion 21 has an arm side edge portion 26 facing the +X direction and the −Y direction. This arm side edge 26 can face the base side edge 131 in the Y direction, and forms a gap G between it and the base side edge 131 through which the string S is inserted.

The arm protruding portion 27 protrudes from the arm main body portion 21 along the arm side edge portion 26 in the +Z direction. This arm convex strip 27 has a portion that is continuous with the arm side edge 26 and can face the base side edge 131 in the Y direction. It is preferable that the cross-sectional shape of the arm convex strip 27 perpendicular to the extending direction has an arcuate shape protruding in the +Z direction. The protruding height of the arm protruding portion 27 is not particularly limited, but is, for example, more than half and less than one time the thickness of the arm main body portion 21 in the Z direction.

The engaging portion 30 protrudes from the tip portion 23 of the arm body portion 21 in the +X direction. Specifically, the engaging portion 30 includes a column portion 31 erected on the tip portion 23 of the arm body portion 21 and a claw portion 32 protruding from the column portion 31 in a direction orthogonal to the Z direction. Further, the claw portion 32 has a flat portion 321 facing in the −Z direction. The Z-direction dimension of the column portion 31 from the surface portion 24A of the arm body portion 21 to the flat portion 321 of the claw portion 32 is approximately equal to the Z-direction thickness of the base body portion 11.
Furthermore, an opening is provided between the engaging portion 30 and the base portion 10 that communicates with the gap G between the arm side edge 26 and the base side edge 131 and opens the gap G to the outside of the string adjuster 1. Part A is formed.

In the string adjuster 1 described above, the arm side edge 26 is close to the base side edge 131 in the Y direction, and the arm side edge 26 is located in the −Z direction with respect to the base side edge 131. The base end portion 22 of the arm body portion 21 is elastically deformed so as to be displaced. Then, by inserting the engaging portion 30 through the engaging hole H2, the engaging portion 30 engages with the base portion 10, and the elastically deformed state of the arm portion 20 is maintained.
The configuration of the string adjuster 1 when the engaging portion 30 engages with the base portion 10 will be described below with reference to FIGS. 3 to 5.

As shown in FIG. 3, the arm side edge 26 is arranged so as to approach the base side edge 131 in the X direction from the base end 22 to the distal end 23 of the arm body 21. That is, the dimension in the X direction of the gap G between the arm side edge 26 and the base side edge 131 becomes smaller toward the −Y direction. Note that the end of the base side edge 131 in the -Y direction may contact the arm side edge 26.

As shown in FIG. 4, the arm body portion 21 (specifically, the arm side edge portion 26 of the arm body portion 21 in FIG. 3) increases as it goes from the base end 22 to the distal end portion 23 of the arm body portion 21. It is arranged so as to be displaced in the -Z direction with respect to the base side edge 131. Here, since the arm side edge 26 is displaced in the −Z direction with respect to the base side edge 131, a part of the arm side edge 26 faces the base convex strip 15 in the X direction, and the base A part of the side edge 131 faces the arm protrusion 27 in the X direction.

As shown in FIG. 5, the engaging portion 30 is arranged to pass through the engaging hole H2. Specifically, the column portion 31 is disposed within the engagement hole H2 and can abut against the inner wall of the engagement hole H2 in both the X direction and the Y direction. Further, the claw portion 32 is disposed outside the engagement hole H2, and is disposed so as to overlap the base portion 10 in the Z direction. Thereby, the flat portion 321 of the claw portion 32 faces the surface portion 12A of the base body portion 11 in the Z direction. Further, the front surface portion 24A of the arm body portion 21 faces the back surface portion 12B of the base body portion 11 in the Z direction.
Therefore, by inserting the engaging portion 30 into the engaging hole H2, the arm portion 20 is positioned relative to the base portion 10 in the X direction, the Y direction, and the Z direction.

[String length adjustment procedure]
The procedure for adjusting the length of the string S using the string adjuster 1 will be explained with further reference to FIGS. 6 to 8. The cross section of the string adjuster 1 shown in FIG. 6 corresponds to the cross section taken along the line VI-VI in FIG. 1, and the cross section of the string adjuster 1 shown in FIG. 8 corresponds to the cross section taken along the line VIII-VIII in FIG. Corresponds to the visual section.

It is assumed that the string S forms a ring for enclosing the wearer's waist while passing through a string insertion passage 92 formed in a waist portion 91 of clothing such as pants. First, the user pulls out the string S from the string insertion opening 93, which is the opening of the string insertion passage 92, folds the pulled-out portion of the string S in half, and grasps the string. Hereinafter, the drawn-out portion of the string S in the folded state will be referred to as a string drawn-out portion SP. Here, the user determines the amount of the string S to be pulled out from the string insertion opening 93, that is, the length of the string pull-out part SP, until the length of the ring of the string S in the waist part 91 becomes an appropriate length. shall be adjusted.

Next, the user prepares the string adjuster 1, and as shown in FIG. Insert it. In the present embodiment, the insertion direction of the string pull-out part SP into the gap G may be the +Z direction or the -Z direction.

Next, as shown in FIG. 7, the user elastically deforms the base end portion 22 of the arm body portion 21 and inserts the engaging portion 30 into the engaging hole H2. At this time, the user operates the engagement part 30 while twisting the arm part 20 so that the claw part 32 and the pillar part 31 of the engagement part 30 are inserted through the engagement hole H2 in order. Thereby, the arm side edge 26 and the arm convex line part 27 of the arm part 20 sandwich the string pull-out part SP between the base side edge part 131 and the base convex line part 15 of the base part 10.
Then, the user inserts the tip of the string drawer SP into the string insertion hole H1 of the string adjuster 1. Thereby, the string pull-out part SP comes to be arranged along the surface of the string adjuster 1.

Thereafter, as shown in FIG. 8, the user may accommodate the string adjustment tool 1 and the string pull-out part SP in the string insertion passage 92 via the string insertion opening 93. With the above steps, the adjustment of the length of the ring of the string S by the string adjuster 1 is completed.

[Effects of this embodiment]
(1) As described above, the string adjuster 1 of the present embodiment includes a plate-shaped base portion 10, an arm portion 20 extending from the base portion 10, and a tip portion 23 of the arm portion 20 protruding in the +Z direction. An engaging portion 30 is provided. The base part 10 has a base side edge 131 facing in the -X direction and an engagement hole H2 passing through the base part 10 in the Z direction. It has arm side edges 26 facing each other in the Y direction. When the engaging portion 30 passes through the engaging hole H2, the arm portion 20 is elastic so that the arm side edge portion 26 approaches the base side edge portion 131 in the -X direction and is displaced in the -Z direction. The base side edge 131 and the arm side edge 26 are deformed so that the string S can be held between them.

In such a configuration, the arm portion 20 is maintained in an elastically deformed state by the engagement portion 30 passing through the engagement hole H2, and the string is inserted between the arm side edge 26 and the base side edge 131. S is pinched.
Further, when the arm portion 20 is elastically deformed, the arm side edge portion 26 approaches the base side edge portion 131 in the X direction, and the arm side edge portion 26 is displaced from the base side edge portion 131 in the −Z direction. As a result, the arm section 20 has an elastic force that presses the engagement section 30 against the inner wall of the engagement hole H2 in the base section 10 in the +X direction, and a region of the arm section 20 around the engagement section 30 that engages. Elastic forces act against the parts of the base portion 10 around the matching hole H2 in the +Z direction. For this reason, even when a soft material having flexibility that does not cause discomfort to the wearer of the clothing is used as the material for the string adjuster 1, the engaging portion 30 may not engage with the base portion 10. The condition can be maintained, and the string S can be securely fastened.
Furthermore, when the engaging part 30 is pulled out from the engaging hole H2, the engaging part 30 and the base part 10 communicate with the gap G between the arm side edge part 26 and the base side edge part 131. An opening A can be formed. Thereby, the string S can be taken in and out of the gap G between the arm side edge 26 and the base side edge 131 through the opening A.
Therefore, according to the present embodiment, a string adjuster 1 that can be retrofitted to the string S and suitably used for clothing is provided.

(2) In the present embodiment, the arm portion 20 includes an arm body portion 21 having an arm side edge portion 26, and an arm convex strip portion 27 that protrudes from the arm body portion 21 in the +Z direction along the arm side edge portion 26. , is provided. The base portion 10 also includes a base body portion 11 having a base side edge portion 131 and an engagement hole H2, and a base convex portion 15 that protrudes from the base body portion 11 in the −Z direction along the base side edge portion 131. , is provided.
In such a configuration, as the arm side edge 26 is displaced from the base side edge 131 in the -Z direction, the base protrusion 15 faces the arm side edge 26, and the arm protrusion 27 moves toward the base side. It faces the edge 131. Thereby, the string S can be held between the arm part 20 and the base part 10 more reliably.

(3) In the present embodiment, when the engagement portion 30 is inserted through the engagement hole H2, the arm side edge portion 26 becomes closer to the base side edge portion 131 from the base end portion 22 of the arm portion 20 toward the distal end portion 23. It is arranged so as to be close to in the X direction.
According to such a configuration, the string S can be held between the arm portion 20 and the base portion 10 more reliably.

(4) In the present embodiment, the engaging portion 30 includes a column portion 31 that is erected from the tip portion 23 of the arm portion 20, and a claw portion 32 that protrudes from the column portion 31 in one direction perpendicular to the Z direction. When the engaging part 30 is inserted through the engaging hole H2, the column part 31 is arranged in the engaging hole H2, and the claw part 32 is arranged so as to overlap with the base part 10 in the Z direction.
In such a configuration, when the column part 31 is inserted into the engagement hole H2, the claw part 32 can abut against the base part 10 in the -Z direction, so that the column part 31 is inserted into the engagement hole H2. You can prevent it from falling out. Thereby, the string adjuster 1 can grip the string S more reliably.

(5) In the present embodiment, the base portion 10 (specifically, the base body portion 11) is arranged on the first plate portion 13 having the base side edge portion 131 and on the −Y direction side with respect to the base side edge portion 131. , and a second plate part 14 protruding from the first plate part 13 in the -X direction.
In such a configuration, in a state where the engaging portion 30 is inserted through the engaging hole H2, the elastic force of the arm portion 20 causes the portion of the arm portion 20 around the engaging portion 30 to connect to the base portion around the engaging hole H2. It can be pressed against 10 parts over a wider range. Thereby, the state in which the engaging portion 30 is engaged with the base portion 10 is maintained more suitably.

(6) In addition, in this embodiment, each cross-sectional shape of the base protruding strip 15 and the arm protruding strip 27 has a semicircular shape protruding in the Z direction. can reduce the discomfort caused by
