難であった。However, the above-mentioned conventional buckle requires further improvement in the following points due to its structure.
First, when this type of buckle is made of plastic (usually made of plastic from the viewpoint of required elastic deformation characteristics and molding cost), it is wound around a male tool and a female tool, respectively. When tension is applied to the belt, the male tool and the female tool are each pulled toward the winding side of the belt, so that the jaws 111a of the hooks 111 of the male tool are sufficiently formed on the edge 104 of the window hole 103 of the female tool. In a state in which the male member engages with the female member, and the engaging rod 102 of the male member protrudes the hook portion 111 outward from the window hole 103 of the female member and does not return elastically. The tool is locked, and as a result, the engaging rod 102 of the male tool is liable to undergo plastic deformation inward with time,
After the plastic deformation, the elasticity of the male tool directed to the outside of the engaging rod 102 is lost, so that it is difficult to create a locked state between the male tool and the female tool. Second, it is necessary to increase the thickness of the engaging rod 102 to increase the strength of the engaging rod 102 in order to make such plastic deformation less likely to occur, which makes this type of buckle thin. Was hindered.
Third, release of the locked state between the locked male tool and female tool,
An engaging rod 1 of a male tool that grips the cylindrical body 101 of the female tool with one hand and projects outward from the window 103 of the female tool with the other hand.
02 is pushed into the inside of the cylinder 101 so as to be picked up, and the jaw 111a of the hook 111 is released from the edge 104 of the window hole 103, so that when the hook 111 is pushed in, the finger is pushed. Hooked on the edge of window hole 103 of female tool, hook 1
It was difficult to slide the male tool outward from the female tool while pushing in 11. Therefore, in order to release the locked state between the male tool and the female tool, use a hand that pushes the hook of the male tool and another hand with the belt connected to either the male tool or the female tool. It is necessary to pull and apply tension so that the male tool and the female tool are separated from each other, and it is difficult to release the locked state with one hand.

る寸法に高精度で合わせることができる。The engagement / disengagement member 20 includes a plate 21 having a slit 22 through which a belt C or the like can be inserted, and a pair of members extending integrally from both sides of the plate 21 in the same direction. The elastic leg pieces 23, 23, and a projection 24 provided outside the elastic leg piece 23 from the plate portion 21 toward the extending direction of the elastic leg piece 23. This elastic leg piece 2
Reference numeral 3 denotes a base leg 26 extending from the plate 21 so as to protrude slightly outward from the lateral width of the plate 21, and a base leg 26 which is provided following the base leg 26 and is further closer to the base leg 26. And an assembling operation protruding piece 27 protruding toward
A step surface 28 is provided between the base leg 26 and the assembling operation projection 27.
Are formed. Further, following the assembling operation protruding piece 27, it is extended from the inside of the assembling operation protruding piece 27 so as to extend along the surface of the inner wall 12b of the cylindrical case 10 and the front end thereof is a round edge 25a. A hook-shaped locking portion 25 is provided on the inner wall 12b of the cylindrical case 10 so that the protruding end 25b is directed when the engaging / disengaging member 20 is housed in the cylindrical case 10. A locking jaw edge 25c is formed further inward. Note that the dimension between the distal ends of the assembling operation protruding pieces 27 of the pair of elastic leg pieces 23, 23 is larger than the dimension between the inner side walls of the cylindrical case 10, and therefore, the engagement and disengagement with the cylindrical case 10 is possible. When the member 20 is inserted, the assembling operation protrusion 27 can protrude outward from the operation window 13 of the cylindrical case 10. Further, from a substantially middle position between the pair of elastic leg pieces 23, 23, the engaging / disengaging member 20 is moved toward one of the openings of the cylindrical case 10 in the extending direction of the elastic leg pieces 23. 11, when inserted and housed and assembled, has a length dimension extending to the vicinity of the opening edge of the other opening 11, and has a thickness dimension of the inner upper surface or inner bottom surface of the cylindrical case 10. A straightening rod 29 that is substantially equal in size between them extends. The straightening rod 29 is used to keep the dimension between the inner surface of the top wall and the inner surface of the bottom wall of the cylindrical case 10 uniform, and to allow the locking piece 32 of the male tool B described later to be freely inserted and removed in the cylindrical case 10. It works. That is, as is well known, a box-shaped plastic molded product having a wide surface is likely to be deformed such as a sled. For this reason, depending on molding conditions, the inner surface of the top wall and the inner surface of the bottom wall of the cylindrical case 10 are warped toward the inside of the cylindrical case 10,
As a result, the dimension between the inner surface of the top wall and the inner surface of the bottom wall of the cylindrical case becomes smaller than the thickness of the locking piece 32 of the male tool B separately molded, and the male tool B is inserted into the cylindrical case 10. Male tool B once stored in the case 10
Disadvantageously, it is difficult to pull out of the case 10 from the inside. Here, the correction rod 29 is extended from a position approximately in the middle of the pair of elastic leg pieces 23 of the female tool A as described above, and the inner surface of the top wall and the inner surface of the bottom wall of the case 10 are 1
0, the dimension between the inner surface of the top wall and the inner surface of the bottom wall of the case 10 can be made close to the set dimension. Can be inserted and removed freely. Further, since the rod-shaped correction rod 29 is not easily deformed and its thickness dimension can be maintained with high accuracy, the dimension between the inner surface of the top wall or the inner surface of the bottom wall of the cylindrical case 10 is smaller than the required dimension. The dimensions of the case 10 can be corrected by inserting the correction rod 29 into the case 10 and adjusted to the required dimensions with high accuracy.

１０内に固定することができる。As shown in FIG. 1, the engaging / disengaging member 20 is moved from the elastic leg piece 23 side to the opening 11 of the cylindrical case 10.
Then, the two elastic leg pieces 23 are inserted into the cylindrical case 10 while being bent inward, and the assembling operation protrusion 27 of the engagement / disengagement member 20 faces outward from the operation window 13 of the cylindrical case 10. When the engaging / disengaging member 20 is moved within the cylindrical case 10 to the position, the two elastic leg pieces 23 that have been bent inward are moved to the operation window 13.
Since the assembly operation projecting piece 27 is made to protrude further to return, the assembly operation projecting piece 27 can be protruded outward from the operation window 13, and the stepped surface 2
8 can be hooked on the window edge of the operation window 13.
