Specifically, the threading main body 10 is configured by a linear member made of metal (for example, made of stainless steel).

The first component portion 20 includes a first component body portion 22 extending in the front-rear direction (X1-X2 direction) while gently curving, and a bending position (first bending position) located at the tip of the first component body portion 22. Position ) 26 is bent with respect to the first component main body 22, and has a first component distal end portion 24 that extends in the front-rear direction while gently curving, and the first component main body 22 is located on the rear side. From the (X1 side) toward the front side (X2 side), it curves to one side (Y1 side) in the left-right direction. It is curved so as to substantially match the front-rear direction toward the front side of the component distal end portion 24 . That is, the rear side (bending position 26 side) of the distal end portion 24 of the first component is inclined with respect to the front-rear direction so as to be the other side (Y2 side) in the left-right direction toward the front side. The front portion of the one-component distal end portion 24 extends substantially in the front-rear direction. Note that the front portion of the first component body portion 22 is inclined with respect to the front-rear direction so that the front side is closer to the Y1 side. The portion on the rear side of the first component tip portion 24 is bent at a bending position 26 .

On the other hand, the second component portion 30 includes a second component body portion 32 that extends in the front-rear direction (X1-X2 direction) while gently curving, and a bending position (second 2 bending position) 36 with respect to the second component main body 32, and has a second component distal end portion 34 extending in the front-rear direction while gently curving, and the second component main body 32 is It curves from the rear side (X1 side) toward the front side (X2 side) toward the other side (Y2 side) in the left-right direction, and the tip portion 34 of the second component portion is tilted with respect to the front-rear direction. It is curved so as to substantially match the front-rear direction toward the front side of the distal end portion 34 of the second component portion. In other words, the rear side (bending position 36 side) portion of the distal end portion 34 of the second component is inclined with respect to the front-rear direction so as to be on one side of the left-right direction (Y1 side) toward the front side. The front portion of the two-component distal end portion 34 extends substantially in the front-rear direction. In addition, the front portion of the second component body portion 32 is inclined with respect to the front-rear direction so as to be closer to the Y2 side toward the front side. The portion on the rear side of the two-component distal end portion 34 is bent at a bending position 36 . Between the bending positions 26 and 36 (that is, inside an insertion portion 38 (described later)), a gap 17 for threading is provided.

The front portion of the first component body portion 22 and the front portion of the second component body portion 32 intersect at a position G, and the portion 22a on the front side of the position G in the first component body portion 22 , the portion 32a on the front side of the position G in the second component body portion 32, the first component tip end portion 24, and the second component tip end portion 34 form a rectangular frame-shaped insertion portion 38. be done. A thread is inserted through the insertion portion 38 . The front portion of the first component body portion 22 and the front portion of the second component body portion 32 intersect at position G while being in contact with each other. and the front portion of the second component main body portion 32 may intersect at a distance (i.e., two front portions at a distance in a direction perpendicular to the X1-X2 direction and the Y1-Y2 direction). parts may intersect).

In addition, the portion 22b on the rear side of the position G of the first component body portion 22 and the portion 32b on the rear side of the position G of the second component body portion 32 are located behind the first component body portion 22.

Since the threading main body 10 is formed of a flexible linear member, the first component main body 22, the second component main body 32, the first component distal end 24, the second component main body 22, the second component main body 32, the first component tip 24, the second component main body Even if the front end portion 34 of the component is bent as described above and is deformed from a bent state (referred to as a basic state) through the bending positions 26 and 36, it is restored to the basic state by a restoring force.

For example, when the threading main body portion 10 is inserted into the cylindrical portion 208 of the bobbin holder 201, the threading main body portion 10 becomes thin within the cylindrical portion 208, and the first component portion 20 becomes linear as a whole. (that is, the curved state of the first component main body portion 22 and the first component distal end portion 24 becomes a nearly linear state, and the degree of bending at the bending position 26 is reduced), and the second configuration The portion 30 is almost linear as a whole (that is, the curved state of the second component main body portion 32 and the second component distal end portion 34 is nearly linear, and the degree of bending at the bending position 36 is becomes smaller), the insertion portion 38 at the tip of the threading main body portion 10 is also elongated, but by removing from the cylindrical portion 208, the portion removed from the cylindrical portion 208 is restored by the restoring force. Therefore, the elongated shape of the insertion portion 38 inside the cylindrical portion 208 is restored by being exposed from the cylindrical portion 208 . However, when the portion other than the insertion portion 38 is accommodated in the cylindrical portion 208, the portion 22b (the portion behind the position G of the first component main body portion 22) and the portion 32b (second component) The rear portion of the main body portion 32 from the position G) is inside the tubular portion 208 and is deformed, so that the insertion portion 38 is restored according to the degree of deformation of the portions 22b, 32b. Become.

Next, the fixing portion 40 is a metal (for example, brass or copper) tubular member having an insertion hole, and is located at the rear end portion of the first component body portion 22 (that is, from the position G).

Further, the length a1 of the tip portion 52 in the front-rear direction is approximately 1/10 of the length in the front-rear direction of the columnar portion 54 (length a2+length a3+length a4).

Here, the tip portion 52 has a substantially hexagonal columnar shape with a larger diameter than the columnar portion body portion 54-2, and the peripheral surface of the tip portion 52 is composed of six square-shaped (strictly trapezoidal) planes. The diameter of the tip portion 52 increases from the front side (X2 side) to the rear side (X1 side).

The reason why the diameter of the tip portion 52 is larger than that of the column body portion 54-2 is that the diameter of the hole portion 60 is larger toward the front side, so that the thickness between the outer surface of the grip portion 50 and the hole portion is increased. This is to ensure

In addition, the tip end portion 54-1 of the columnar portion has a hexagonal prism shape whose diameter decreases from the front side to the rear side. In addition, the six surfaces forming the tip end portion 54-1 of the columnar portion 54-1 are curved in a substantially arcuate shape.

A rear hole portion 63 is formed by the second hole portion 64 and the third hole portion 66 .

The first hole 62, the second hole 64, and the third hole 66 all have cross-sectional shapes (shapes taken along a cross section perpendicular to the X1-X2 direction) that are the same as those of the grip portion 50. It is circular (may be substantially circular) centering on an axis (virtual axis) U in the X1-X2 direction. That is, the axis (center line) of the first hole portion 62, the axis (center line) of the second hole portion 64, and the axis (center line) of the third hole portion 66 are located on the same straight line.

Here, the first hole (front hole) 62 includes a first hole end (front hole end) 62-1 provided on the front side of the grip portion 50 and a first hole end 62-. 1 and a first hole main body (front hole main body) 62-2 connected from the rear end of the first hole main body 62-2.

The inner diameter of the first hole end portion 62-1 is formed so as to decrease from the front side to the rear side, and the length in the front-rear direction (unit length (for example, a predetermined length such as N mm)) The amount of change in the size of the inner diameter becomes smaller from the front side to the rear side. That is, the curve 62-1N indicating the first hole end portion 62-1 in the vertical cross-sectional shape shown in FIG. It is inclined so that it becomes smaller toward the rear. Since the first hole end portion 62-1 opens wider toward the front side, the tubular portion 208 of the bobbin holder 201 can be easily inserted into the first hole portion 62. As shown in FIG.

In addition, the inner diameter of the first hole body portion 62-2 is formed so as to decrease from the front side to the rear side, and the length in the front-rear direction (unit length (for example, a predetermined length such as N mm) ) is the same from the front end to the rear end of the first hole body 62-2. That is, the straight line 62-2N indicating the first hole main body 62-2 in the vertical cross-sectional shape shown in FIG. In other words, the inner peripheral surface of the first hole body portion 62-2 exhibits the shape of a truncated cone peripheral surface, and the longitudinal cross-sectional shape of the first hole body portion 62-2 is the same as that of the first hole body portion 62. It can be said that it exhibits a tapered shape in which the width decreases toward the depth side of -2. The diameter R1 of the front end portion of the first hole main body portion 62-2 is larger than the rear diameter R2 of the first hole main body portion 62-2 (R1>R2). The diameter of the rear end portion of the first hole portion end portion 62-1 and the diameter of the front end portion of the first hole portion body portion 62-2 are the same as the diameter R1. Since the vertical cross-sectional shape of the first hole main body portion 62-2 is tapered, as will be described later, the cylindrical portion 208 of the bobbin holder 201 is aligned with the inner peripheral surface of the first hole main body portion 62-2. Easy to stick. Also, the amount of change in the inner diameter with respect to the length of the first hole main body 62-2 in the front-rear direction is the same from the front end to the rear end of the first hole main body 62-2. Therefore, it can be said that the cylindrical portion 208 can be easily inserted up to the wall portion 62W, which is the end portion on the far side of the first hole main portion 62-2.

As a result, an annular wall portion 62W is provided at the rear end portion of the first hole body portion 62-2.

The third hole portion (rear portion of the rear hole portion) 66 is formed to have the same diameter from the front end to the rear end, and the inner circumference of the third hole portion 66 presents a cylindrical peripheral surface. there is The diameter R4 of the third hole portion 66 is formed larger than the diameter R3 of the rear end portion of the second hole portion 64 (R4>R3). Thereby, an annular wall portion (second wall portion) 66W is provided at the front end portion of the third hole portion 66 .

The length of the first hole 62 in the front-rear direction (the sum of the length b1 in the front-rear direction of the first hole end 62-1 and the length b2 in the front-rear direction of the main body 62-2 of the first hole) ) is a length equal to or greater than half of the length of the hole portion 60 in the front-rear direction (the length obtained by adding the length b1 and the length b2 and the length b3 and the length b4 of the second hole portion 64 in the front-rear direction). The length b1 is 1/10 or less of the length of the first hole portion 62 in the front-rear direction (the sum of the length b1 and the length b2). Moreover, the length b3 is formed shorter than the length b4.

Since the hole portion 60 is configured as described above, when the tubular portion 208 of the bobbin holder 201 is inserted into the first hole portion 62, the tip of the tubular portion 208 is positioned in the first hole main portion 62-2. from the front end to the rear end of the first hole main body 62-2, and the tip of the tubular portion 208 inserted into the first hole main body 62-2 first contacts the far side Since the grip portion 50 is stretchable, the first hole main body portion 62-2 is expanded by the cylindrical portion 208, the inner diameter of the first hole main body portion 62-2 is increased, and the second The inner peripheral surface of the one-hole body portion 62-2 is in close contact with the outer peripheral surface of the cylindrical portion 208, and the tip of the cylindrical portion 208 is in contact with the wall portion 62W.

Note that the relationship between the longitudinal length L2 of the portions 22b and 32b of the threading main body 10 and the longitudinal length S of the tubular portion 208 is at least After insertion, the insertion portion 38 is exposed from the rear end side of the tubular portion 208 in a state in which the tip of the tubular portion 208 is in contact with the wall portion 62W.
