Thus, in the inner space 10 of the main body 1, the string-shaped body W is made to bite the hole edge portion 21a ′ of the through hole 21a of the leg portion 21. (Figure 4)

That is, according to the fastener R according to this embodiment, (1) the leg portion of the lock body 2 in a state where the operation head 20 is pressed and operated to elastically deform the operation head 20. The string-like body W can be passed through the main body 1 through the through hole 21a of the body 21, and the fastener R can be moved along the string-like body W to a desired position of the string-like body W in this state. . (2) In addition, after moving the fastener R along the string-shaped body W to a desired position of the string-shaped body W in this way, the operation head 20 is completely released by pressing the operating head 20. However, the leg portion 21 of the lock body 2 is elastically returned and is moved in the direction of being pulled out from the communication hole 11 of the main body 1 by the elastic return. The hole edge portion 21a ′ of the through hole 21a of 21 can be bited, and the fastener R can be fastened to the string-shaped body W at this desired moving position. (3) Further, from the state where the fastener R is fastened to the desired position of the string-like body W in this manner, the operation head 20 is pressed again to elastically deform the operation head 20, It is possible to move the leg portion 21 of the lock body 2 to the inner side of the internal space 10 of the main body 1 to release the state in which the hole edge portion 21a ′ of the through hole 21a of the leg portion 21 is bitten by the string-like body W. Therefore, the fastening state of the fastener R to the string W can be released, and the fastener R can be moved to the desired position along the string W again. (4) Further, since it is not necessary to provide means for elastically ejecting the lock body 2 inside the main body 1, the size of the main body 1 in the direction orthogonal to the longitudinal direction of the string-like body W, and further, this direction The size of the fastener R can be made as small as possible without hindrance. In particular, the main body 1 can be configured to be long along the length direction of the string-like body W and have a shape as short as possible and inconspicuous in the direction orthogonal to the length direction of the string-like body W. Further, since the size of the fastener R in the pressing direction of the operating head 20 of the lock body 2 can be made as small as possible, the fastener R can be easily gripped during this pressing operation. (5) Further, it is reasonable that the operation head 20 of the lock body 2 is configured to be long along the length direction of the string-shaped body W so that the operation head 20 has a sufficient elastic return force. it can. Further, it is possible to secure an operation surface for pressing the lock body 2 as large as possible along the length direction of the string-shaped body W. Further, since the operating head 20 itself plays a role of a spring for biting the hole edge portion 21a ′ of the through hole 21a of the leg portion 21 in the string-shaped body W, it has a rational structure and To release this bite operation head 2
With the pressing operation of 0, all the pressing force can be applied to the operation head 20 without waste.

In this embodiment, the operating head 20 is composed of a pair of elastic pieces 20a, 20a which elastically deform on both sides sandwiching the protruding position of the leg portion 21 by the pressing operation. Therefore, both the movement of the leg portion 21 by the pressing operation and the movement of the leg portion 21 by the release of the pressing operation can be stably performed.

However, unlike this embodiment, the operating head 20 may be formed of one elastically deformable elastic piece 20a that projects laterally from the position where it is connected to the leg 21. .

Further, in this embodiment, the main body 1
A concave portion 15 that is recessed toward the internal space 10 side of the main body 1 is formed in a portion of the side portion 12 facing the operation head 20 of the lock body 2.

A groove-shaped concave portion 15 extending in the longitudinal direction of the main body 1 is formed therein. The recess 15 is formed so as to make the place where the communication hole 11 is formed the deepest, and the bottom surfaces 15a of the recesses 15 on both sides of the communication hole 11 from the end of the main body 1 respectively. Communication hole 11
The inclined surface 15b gradually lowers as it goes to.

In this embodiment, the operating head 20 of the lock body 2 has a width dimension that fits within the width of the recess 15, and the operating head 20 fits within the recess 15. In this state, the leg portion 21 is inserted into the internal space 10 of the main body 1 through the communication hole 11.

More specifically, when the operating head 20 is not pressed against the main body 1, the tip portions 20a 'of the pair of elastic pieces 20a, 20a constituting the operating head 20 are attached to the bottom surface 15a of the recess 15. While being in contact with each other, the inclined surface 15b allows the operation head 20 to move from the tip 20a '
The operating head 20 is housed in the concave portion 15 in such a state that the distance between the operating head 20 and the bottom surface 15a of the concave portion 15 becomes wider toward the connecting position of the leg portion 21 in. Then, the operation head 20 is directed toward the main body 1 side up to a position where the protruding side surface of the leg portion 21 of the operation head 20 is brought into close contact with the bottom surface 15a of the recess 15.
The pressing operation can be performed while 0 is elastically deformed.

As a result, in this embodiment, it is possible to further reduce the size of the fastener R in the direction orthogonal to the longitudinal direction of the string-shaped body W.

Further, in this embodiment, the main body 1
The distance between the facing hole edges 11c, 11c in the communicating hole 11 in the direction crossing the passing direction of the string-like body W is larger than the thickness dimension of the leg portion 21 of the lock body 2 in the passing direction. Is also made larger.

The communication hole 11 of the main body 1 includes (1) a central hole portion 11a that is slightly wider than the width dimension of the leg portion 21 of the lock body 2, and (2)
On both sides of the central hole portion 11a, side hole portions 11b each having a width slightly smaller than the width dimension of the leg portion 21 of the lock body 2 are provided. (3) Then, the central hole 11a and the side hole 11
Due to the dimensional difference of b, the first groove 11d for accommodating the side edge portion 21c in the protruding direction of the leg portion 21 is formed in both hole wall portions in the length direction of the main body 1 in the communication hole 11. .

The lock body 2 inserted into the communication hole 11 at the central hole portion 11a of the communication hole 11 in this manner.
Between the one surface 21b of the leg portion 21 and the hole edge portion 11c in the side hole portion 11b facing the one surface 21b in a direction intersecting with the passing direction of the string-like body W, and the lock body 2 The other surface 21b of the leg portion 21 and the other surface 2
Between the side edge portion 11b facing 1b and the hole edge portion 11c in the direction crossing the through direction of the string-shaped body W,
A part of the cord-like body W on the outside of the bending of the cord-like body W bent by the elastic return of the operating head 20 after the string-like body W is passed through the through hole 21a of the leg portion 21 of the lock body 2. Is the main body 1
It is designed to come in from inside. (Figure 4)

As a result, in this embodiment, when the fastener R is fastened to the string W, the string W is attached.
Can be bent as much as possible, and a part of the bent portion of the string-like body W bent in this way can be inserted into the communication hole 11 from the inside of the main body 1 and pushed to the hole edge portion 11c of the communication hole 11. You can guess it,
The fastening force to the string-shaped body W can be secured more strongly.

Since the bent portion of the string-like body W is inserted into the communication hole 11 from the inside of the main body 1, the leg 21 of the lock body 2 outside the main body 1 is fastened to the string-like body W. It is possible to secure a large movement dimension toward the front side, and thereby, the elastic deformation amount of the operating head 20 of the lock body 2 in this fastening state can be reduced. As a result, fatigue of the operating head 20 over time, that is, reduction of the elastic deformation force of the operating head 20 due to the operating head 20 remaining largely elastically deformed in the fastening state. It can be prevented as much as possible.
