It is formed more convex than the other regions with respect to the circular region as shown in FIGS. 7 and 8. As a result, when the second component 3 rotates with respect to the first component 2, the sliding surface between the first component 2 and the second component 3 is limited to the convex portions 311a and 312a, and thus is convex. It is possible to prevent the portions other than the shaped portions 311a and 312a from being scratched.

The long side edge portions 311b and 312b are formed in the same plane as the pressing surface 30a, and are arranged on the side opposite to the side edge portion 310b of the second support wall 310. The long side edge portions 311b and 312b are formed so as to be separated from the second support wall surface 310a toward the operation portion 313 side from the pressing surface 30a side. The short side edge portions 311c and 312c are erected from the operation unit 313 (second contact surface 313b) and are connected to the long side edge portions 311b and 312b so as to form a convex curved surface.

Therefore, each of the pair of second side walls 311 and 312 extends closer to the operating portion 313 than the tip of the second arm portion 42 in the axial direction of the second arm portion 42. Each of the pair of second side walls 311 and 312 is from the holding portion 30 side to the operating portion 313 side, except for the convex curved connecting portion between the long side edge portions 311b and 312b and the short side edge portions 311c and 312c. The height from the second support wall surface 310a to the long side edge portions 311b and 312b increases toward the short edge portions 311c and 312c. As a result, as illustrated in the front view of FIG. 3, the long edge portions 311b and 312b are arranged along the first support wall 210, and the short edge portions 311c and 312c are the outer surfaces of the support base portion 213. It is arranged along the 213c. Therefore, since the connecting portion of the first component 2 and the second component 3 has a smooth outer shape with less unevenness, it is possible to prevent the fabric from being caught in the connecting portion and prevent the fabric from being damaged.

The operation unit 313 has a second end surface 313a and a second contact surface 313b as surfaces arranged on the side of the first component 2 and the torsion spring 4. The operation unit 313 has an operation surface 313c as a surface opposite to the second contact surface 313b.

The second end surface 313a is integrated with the second support wall 310 and the pair of second side walls 311 and 312 to form the second recess 32.

Arranged as a contactable surface. As a result, the second contact surface 313b functions as a stopper when operated in the opening direction by the user, so that the operability of the necktie stopper 1 can be improved and the necktie stopper 1 can be prevented from being damaged.

The thickness of the operation unit 313 is set to be larger than the thickness of the second support wall 310 by providing a step by the second end surface 313a. As a result, it is possible to improve the strength of the operation unit 313 to which a load is applied when the user operates the operation unit in the opening direction.

The operation surface 313c is a surface that is pressed when the user operates the necktie stopper 1 in the opening direction.

(Manufacturing method of tie stopper 1)
Next, a method for manufacturing the necktie stopper 1 having the above configuration will be described.

First, in the parts manufacturing process, the first part 2 and the second part 3 are manufactured, respectively. The first component 2 and the second component 3 are manufactured using various metal materials (including various alloys) such as gold, silver, platinum, brass, copper, steel, tin, and iron. The first part 2 and the second part 3 are manufactured by appropriately combining various metal processing methods such as casting, metal casting, forging, forging, pressing, bending, cutting, engraving, engraving, polishing, and plating.

At that time, each of the first part 2 and the second part 3 may be manufactured as an integral part by casting, for example. Further, each of the first component 2 and the second component 3 may be manufactured by separately manufacturing a plurality of parts and fixing the plurality of parts by a fixing means such as welding or an adhesive. As a plurality of parts, the first part 2 is manufactured from a part constituting the decorative portion 20 and a component constituting the support portion 21, and the second component 3 includes a component constituting the holding portion 30. It may be manufactured from the parts constituting the supported portion 31. The configuration of the plurality of parts is not limited to the above example.

Further, the first component 2 and the second component 3 may be manufactured of the same material or may be manufactured of different materials. The first part 2 and the second part 3 may be manufactured by the same manufacturing method or may be manufactured by different manufacturing methods.

Next, in the assembly process, the torsion spring 4 is arranged between the first support wall 210 of the first component 2 and the second support wall 310 of the second component 3. Then, the shaft body 50 is inserted in a state where the first through hole 52, the second through hole 53, and the coil portion 40 are arranged coaxially, and both ends thereof are fixed with rivets 51 to form the first component 2. The second component 3 is rotatably connected to the second component 3. In this way, the tie stopper 1 is manufactured.

As a result, the torsion spring 4 does not come into direct contact with the fabric even when the fabric of the necktie and the garment is inserted to the support base 213 side when the necktie 1 is attached, used, and detached. Therefore, it is possible to prevent the fabric from being damaged by the torsion spring 4. Further, since the adhesion of foreign matter (fabric fibers, dust, etc.) to the torsion spring 4 is reduced, the rotational operation of the first component 2 and the second component 3 can be maintained in a smooth state.

Further, the first support wall surface 210a receives the urging force of the torsion spring 4 by coming into contact with the first arm portion 41, and the pair of first side walls 211 and 212 are connected to the second component 3 via the shaft support mechanism 5. Receives a load from the shaft support mechanism 5 by supporting the shaft. At this time, since the reinforcing structure is realized by having the pair of first side walls 211 and 212 erected from both side edge portions 210b of the first support wall 210, respectively, the first support wall 210 and the pair of first side walls The strength of 211 and 212 can be improved.

Further, in the supported portion 31 of the second component 3, the second support wall 310 is arranged on the side opposite to the first support wall 210 with respect to the torsion spring 4, and at least the second arm is on the torsion spring 4 side. It has a second support wall surface 310a with which the portion 42 abuts. Further, a pair of second side walls 311 and 312 are erected from both side edge portions 310b of the second support wall 310 on the torsion spring 4 side, respectively, and are arranged facing each of the pair of first side walls 211 and 211. Then, it is pivotally supported by each of the pair of first side walls 211 and 211 via the shaft support mechanism 5.

Therefore, the second support wall 310 and the pair of second side walls 311 and 312, together with the first support wall 210 and the pair of first side walls 211 and 212, serve as a cover for incorporating the coil portion 40 and the first arm portion 41. Function. As a result, the torsion spring 4 does not come into direct contact with the fabric when the necktie stopper 1 is attached, used, or detached, so that the fabric can be prevented from being damaged by the torsion spring 4. Further, since the adhesion of foreign matter to the torsion spring 4 is reduced, the rotational operation of the first component 2 and the second component 3 can be maintained in a smooth state.

Further, the second support wall surface 310a receives the urging force of the torsion spring 4 by coming into contact with the second arm portion 42, and the pair of second side walls 311 and 312 are paired with the first one via the shaft support mechanism 5. By being pivotally supported by the side walls 211 and 211, the load from the shaft support mechanism 5 is received. At this time, since the reinforcing structure is realized by having the pair of second side walls 311 and 312 erected from both side edge portions 310b of the second support wall 310, respectively, the second support wall 310 and the pair of second side walls The strength of 311 and 312 can be improved.

(Second embodiment)
FIG. 9 is an exploded perspective view showing an example of the necktie stopper 1 according to the second embodiment.

The necktie stopper 1 according to the present embodiment is a modification of the configuration of the shaft support mechanism 5 as compared with the first embodiment. Since other configurations are the same as those of the first embodiment, the shaft support mechanism 5 according to the present embodiment will be mainly described below.

The shaft support mechanism 5 has a protrusion-like shape formed in each of the insertion holes 55 formed in each of the pair of first side walls 211 and 212 and the pair of second side walls 311 and 312 and inserted into the insertion holes 55. It is composed of a shaft body 54. The shaft body 54 is rotatably connected to the first component 2 and the second component 3 by being inserted into the insertion holes 55 arranged coaxially.

In the assembly process in the method for manufacturing the necktie stopper 1 having the above configuration, for example, a jig is used to expand the pair of second side walls 311 and 312 so that the distance between the pair of second side walls 311 and 312 becomes large. In the state, the first component 2 is arranged inside the state. Then, the protruding shaft body 54 formed on the second side wall 311 and 312 is positioned so as to be inserted into the insertion holes 55 formed on the facing first side walls 211 and 212, and the jig is removed by removing the jig. The first component 2 and the second component 3 are rotatably connected.

The insertion hole 55 is formed in one of a pair of first side walls 211, 212 and a pair of second side walls 311 and 312, and the protruding shaft body 54 is a pair of first side walls 211, 212 and a pair. It suffices if it is formed on the other side of the second side wall 311 and 312. Therefore, instead of the case illustrated in FIG. 6, the insertion hole 55 is formed in the pair of second side walls 311 and 312, and the protruding shaft body 54 is formed in the pair of first side walls 211 and 212. You may do so.
