ここで、雄部材Aを構成する各部材のうち、ベルト取付部10、ガイド片21および操作片31は、金属によって形成されている。金属としては、アルミニウム、ステンレス、マグネシウム、チタン、鉄、銅、亜鉛、あるいは、これらの合金などの金属を挙げることができる。中でも、アルミニウム、マグネシウム、チタンなどの軽金属やこれらの合金で形成するのが好ましい。   Here, among the members constituting the male member A, the belt mounting portion 10, the guide piece 21, and the operation piece 31 are made of metal. Examples of the metal include metals such as aluminum, stainless steel, magnesium, titanium, iron, copper, zinc, and alloys thereof. Especially, it is preferable to form with light metals, such as aluminum, magnesium, titanium, and these alloys.

実際に、これらベルト取付部10、ガイド片21および操作片31を製造するには、図4の配置状態において、金型内に、ベルト取付部形成用キャビティ、ガイド片形成用キャビティおよび操作片形成用キャビティを形成するとともに、これらをT字状のランナで連結し、このランナを通して各キャビティ内に溶融金属を充填する。すると、ベルト取付部10、ガイド片21および操作片31がランナで連結されたダイキャスト製品が得られる。この状態において、ベルト取付部10、ガイド片21および操作片31からランナを切り取れば、ベルト取付部10、ガイド片21および操作片31を得ることができる。   Actually, in order to manufacture the belt attachment portion 10, the guide piece 21, and the operation piece 31, in the arrangement state of FIG. 4, the belt attachment portion formation cavity, the guide piece formation cavity, and the operation piece formation are formed in the mold. These cavities are formed and connected with a T-shaped runner, and molten metal is filled into each cavity through the runner. Then, a die-cast product in which the belt attaching portion 10, the guide piece 21, and the operation piece 31 are connected by the runner is obtained. In this state, if the runner is cut off from the belt attachment portion 10, the guide piece 21 and the operation piece 31, the belt attachment portion 10, the guide piece 21 and the operation piece 31 can be obtained.

And is accommodated in the female member B. Specifically, it is formed by a strip shape in which the thickness dimension is slightly thinner than the thickness of the belt mounting portion 10 and the width direction dimension is thinner (about 1/2 or less) than the thickness dimension. Therefore, since the dimension in the width direction is extremely thin compared to the thickness dimension, the operation piece 31 can be greatly elastically deformed in the inner and outer directions.

弾性腕片41には、図5に示すように、弾性腕片41を形成する樹脂によって、ベルト取付部結合部42、ガイド片覆部43、操作片結合部44がそれぞれ連続的にかつ一体的に形成されている。
ベルト取付部結合部42は、一対の弾性腕片41を連結するとともに、連結部16の外表面(表裏面および端面)を覆う。
ガイド片覆部43は、ガイド片21の表裏面を覆うとともに、表裏面外周縁に沿って突出する矩形枠状の突条43Aを備えている。そのため、ガイド片覆部43は雌部材Bの内面と摺接されている。
操作片結合部44は、操作片31の連結部36の表裏面を覆い、かつ、操作片31の先端を覆う先端覆部45を備えるとともに、操作片結合部44の厚みは操作片31の厚みとほぼ等しく形成されている。つまり、弾性腕片41を形成する樹脂材が、各操作片31の対向面側に、これらの厚みと略同じ厚みで連続して形成されている。
As shown in FIG. 5, the belt attachment portion coupling portion 42, the guide piece cover portion 43, and the operation piece coupling portion 44 are continuously and integrally formed on the elastic arm piece 41 by the resin forming the elastic arm piece 41. Is formed.
The belt attachment portion coupling portion 42 couples the pair of elastic arm pieces 41 and covers the outer surface (front and back surfaces and end surfaces) of the coupling portion 16.
The guide piece covering portion 43 includes a rectangular frame-shaped protrusion 43A that covers the front and back surfaces of the guide piece 21 and protrudes along the outer periphery of the front and back surfaces. Therefore, the guide piece cover 43 is in sliding contact with the inner surface of the female member B.
The operation piece coupling portion 44 includes a front end cover portion 45 that covers the front and back surfaces of the connection portion 36 of the operation piece 31 and covers the distal end of the operation piece 31. The thickness of the operation piece coupling portion 44 is the thickness of the operation piece 31. Are formed almost equally. That is, the resin material forming the elastic arm piece 41 is continuously formed on the facing surface side of each operation piece 31 with a thickness substantially the same as these thicknesses.

以上の構成部材、つまり、ベルト取付部10、ガイド片21、操作片31および弾性腕片41を一体的に形成して雄部材Aを製造するには、樹脂のインサート成形により製造することができる。
まず、金型に、ガイド片21を有するベルト取付部10と操作片31とを図4に示す位置関係に配置するスペースを形成しておくとともに、これらの間に図5に示す樹脂充填空間(キャビティ)を形成しておく。
In order to manufacture the male member A by integrally forming the above constituent members, that is, the belt attaching portion 10, the guide piece 21, the operation piece 31, and the elastic arm piece 41, it can be manufactured by resin insert molding. .
First, a space for arranging the belt mounting portion 10 having the guide piece 21 and the operation piece 31 in the positional relationship shown in FIG. 4 is formed in the mold, and a resin filling space (shown in FIG. Cavity) is formed.

この状態において、溶融樹脂を樹脂充填空間(キャビティ)に射出充填したのち、冷却固化する。溶融樹脂は、弾性腕片41、ベルト取付部結合部42、ガイド片覆部43、操作片結合部44を構成する空間を充填する。
同時に、図6に示すように、ベルト取付部10、ガイド片21および操作片31の表裏に貫通して設けられた貫通孔18,24,38に溶融樹脂が充填されることによって、弾性腕片41とベルト取付部10、ガイド片21および操作片31とが結合される。ここで、弾性腕片41の長手方向(差込方向)に沿った略中心軸の延長線上に、ベルト取付部10との結合用の貫通孔18と、操作片31の結合用の貫通孔38が位置されている。このようにしたことにより、一対の弾性腕片41が弾性変形した際にも、ベルト取付部10や操作片31の結合が維持できる構造になっている。なお、貫通孔38に代えて、突起としてもよい。
また、図2に示すように、操作片31のガイド片21側(幅方向中央側)には、操作片結合部44を備えているが、操作片31と操作片結合部44との境界は、上記開口部58の縁部より内側に形成される。
In this state, the molten resin is injected and filled into the resin filling space (cavity) and then cooled and solidified. The molten resin fills the space constituting the elastic arm piece 41, the belt attachment portion coupling portion 42, the guide piece cover portion 43, and the operation piece coupling portion 44.
At the same time, as shown in FIG. 6, the molten arm is filled with the molten resin in the through holes 18, 24, 38 provided through the front and back of the belt attaching portion 10, the guide piece 21, and the operation piece 31, so 41 and the belt attaching part 10, the guide piece 21, and the operation piece 31 are couple | bonded. Here, on the extension line of the substantially central axis along the longitudinal direction (insertion direction) of the elastic arm piece 41, the through hole 18 for coupling to the belt mounting portion 10 and the through hole 38 for coupling the operation piece 31. Is located. By doing in this way, even if a pair of elastic arm piece 41 elastically deforms, it has a structure which can maintain the coupling | bonding of the belt attaching part 10 and the operation piece 31. FIG. Instead of the through hole 38, a protrusion may be used.
As shown in FIG. 2, the operation piece 31 is provided with an operation piece coupling portion 44 on the guide piece 21 side (width direction center side), but the boundary between the operation piece 31 and the operation piece coupling portion 44 is , Formed on the inner side of the edge of the opening 58.

雌部材Bは、図1〜図3に示すように、全体が金属のダイキャスト成形によって、表面壁51、裏面壁52、両側の側壁53を有する扁平四角形状の筒体54に形成されている。なお、ここで用いる金属は、雄部材Aのベルト取付部10や操作片31を形成した金属と同じであるが、同じでなくてもよい。筒体54には、一端に差込口55が形成されているとともに、内部に雄部材Aの差込部20が挿入される収納空間56が形成されている。
表面壁51は、差込口55側縁が裏面壁52および側壁53よりも長く形成され、雌部材Bに雄部材Aが挿入、係合された状態において、雄部材Aの表面側(ベルト取付部10の表面側)を覆う大きさに形成されている。
裏面壁52は、先端側(差込口55とは反対側)が表面壁51よりも長く延長して形成されているとともに、その延長部分にベルト取付部としてのベルト取付孔57が形成されている。
側壁53には、収納空間56の中間位置より僅か差込方向奥側に、操作片31を雌部材Bの外部に露出させる開口部58が形成されているとともに、これより奥側に、雄部材Aの係合部35が係合される被係合部59が表面壁51および裏面壁52に設けられている。
被係合部59は、側壁53から筒体54の内部に向かってかつ差込口55に向かって斜めに突出され、その突出端が略三角形状に形成されている。
As shown in FIGS. 1 to 3, the female member B is formed into a flat quadrangular cylinder 54 having a front wall 51, a back wall 52, and side walls 53 on both sides by metal die casting. . In addition, although the metal used here is the same as the metal which formed the belt attachment part 10 and the operation piece 31 of the male member A, it does not need to be the same. The cylindrical body 54 is formed with an insertion port 55 at one end and a storage space 56 into which the insertion portion 20 of the male member A is inserted.
The front wall 51 is formed so that the side edge of the insertion port 55 is longer than the back wall 52 and the side wall 53, and the male member A is inserted into and engaged with the female member B. It is formed in a size that covers the surface side of the portion 10.
The back wall 52 is formed such that the front end side (the side opposite to the insertion port 55) extends longer than the front wall 51, and a belt mounting hole 57 as a belt mounting portion is formed in the extended portion. Yes.
The side wall 53 is formed with an opening 58 that exposes the operation piece 31 to the outside of the female member B slightly on the back side in the insertion direction from the intermediate position of the storage space 56. An engaged portion 59 to which the A engaging portion 35 is engaged is provided on the front wall 51 and the back wall 52.
The engaged portion 59 protrudes obliquely from the side wall 53 toward the inside of the cylindrical body 54 and toward the insertion port 55, and the protruding end is formed in a substantially triangular shape.

表面壁51および裏面壁52は、差込方向のほぼ中間で、両側壁53を互いに近づけるように切り欠かれており、表面からみてくびれた形状を呈している。このくびれは、差込口55側から先端側に向かうに従って、その幅方向の寸法が次第に狭くなった後、広がるように形成されており、連続する曲面形状に形成されるのが好ましい。このくびれた部分に対応する側壁53に開口部58が形成される。なお、この切り欠きは、操作片31を押圧して係合部35を被係合部59から外す変形量を確保できるように形成される。   The front wall 51 and the back wall 52 are notched so as to bring the side walls 53 closer to each other at approximately the middle in the insertion direction, and have a constricted shape when viewed from the front surface. The constriction is formed so as to expand after the dimension in the width direction gradually narrows from the insertion port 55 side toward the distal end side, and is preferably formed in a continuous curved surface shape. An opening 58 is formed in the side wall 53 corresponding to the constricted portion. The notch is formed so as to secure a deformation amount that presses the operation piece 31 and removes the engaging portion 35 from the engaged portion 59.

<実施形態の作用・効果>
このような構成において、雄部材Aを雌部材Bに係合させるには、雄部材Aの差込部20を雌部材Bの差込口55から収納空間56に差し込む。すると、差込部20が収納空間56内に差し込まれていくと、差込部20のガイド片21の表裏面(突条43A)が雌部材Bの内面と摺接されながら挿入されていき、差込部20の一対の操作片31の先端部が雌部材Bの被係合部59に当接される。
この際、ガイド片21の表裏面は樹脂材からなるガイド片覆部43で覆われているから、金属製の雌部材Bとの摺接、つまり、金属同士の摺接を回避できる。また、一対の操作片31の先端部が樹脂製の先端覆部45で覆われているから、差込部20の一対の操作片31の先端部が雌部材Bの被係合部59に当接した際の金属同士の摺接を回避できる。
<Operation / Effect of Embodiment>
In such a configuration, in order to engage the male member A with the female member B, the insertion portion 20 of the male member A is inserted into the storage space 56 from the insertion port 55 of the female member B. Then, as the insertion portion 20 is inserted into the storage space 56, the front and back surfaces (projections 43A) of the guide piece 21 of the insertion portion 20 are inserted while being in sliding contact with the inner surface of the female member B. The distal ends of the pair of operation pieces 31 of the insertion portion 20 are brought into contact with the engaged portion 59 of the female member B.
At this time, since the front and back surfaces of the guide piece 21 are covered with the guide piece cover portion 43 made of a resin material, sliding contact with the metal female member B, that is, sliding contact between the metals can be avoided. Further, since the distal end portions of the pair of operation pieces 31 are covered with the resin distal end cover portion 45, the distal end portions of the pair of operation pieces 31 of the insertion portion 20 contact the engaged portion 59 of the female member B. Sliding contact between metals when in contact can be avoided.

ちなみに、摺接する部材が金属同士の場合、金属が欠けたり、あるいは、メッキや表面処理材などが剥がれたりするが、本実施形態のようにすれば、これらの問題を防止できる。特に、本実施形態では、一対の弾性腕片41を形成する樹脂材と、ガイド片21の表裏面に形成された樹脂材からなるガイド片覆部43とは、ベルト取付部結合部42を介して連続して一体的に成形されているから、これらを一体成形できるとともに、全体の強度も高めることができる。   Incidentally, when the members that are in sliding contact with each other are metals, the metal is chipped or the plating or the surface treatment material is peeled off. However, according to the present embodiment, these problems can be prevented. In particular, in the present embodiment, the resin material forming the pair of elastic arm pieces 41 and the guide piece cover portion 43 made of the resin material formed on the front and back surfaces of the guide piece 21 are connected via the belt attachment portion coupling portion 42. Since these are continuously and integrally molded, they can be integrally molded and the overall strength can be increased.

差込部20の一対の操作片31の先端部が雌部材Bの被係合部59に当接した状態から、更に、差込部20を差し込んでいくと、一対の弾性腕片41が差込方向に対して略直交しかつ各操作片31が互いに近づく方向(内側)へ弾性変形されながら差し込まれていく。
やがて、操作片31の係合部35が雌部材Bの被係合部59に対応する位置まで雄部材Aが差し込まれると、内側に弾性変形されていた弾性腕片41が元の状態に弾性復帰するため(外側へ復帰するため)、操作片31の係合部35が雌部材Bの被係合部59に係合される。これにより、雄部材Aが雌部材Bに係合される。
When the insertion portion 20 is further inserted from the state in which the distal end portions of the pair of operation pieces 31 of the insertion portion 20 are in contact with the engaged portion 59 of the female member B, the pair of elastic arm pieces 41 are changed. The operation pieces 31 are inserted while being elastically deformed in a direction (inside) that is substantially orthogonal to the insertion direction and approaches each other.
Eventually, when the male member A is inserted to a position where the engaging portion 35 of the operation piece 31 corresponds to the engaged portion 59 of the female member B, the elastic arm piece 41 elastically deformed inwardly returns to its original state. In order to return (to return to the outside), the engaging portion 35 of the operation piece 31 is engaged with the engaged portion 59 of the female member B. Thereby, the male member A is engaged with the female member B.

雄部材Aが雌部材Bに係合された状態では、ベルト取付部10が雌部材Bの筒体54から突出し、かつ、操作片31が雌部材Bの開口部58から外部に露出されるとともに、弾性腕片41は雌部材Bの内部に収容される。雄部材Aのうちベルト取付部10および操作片31は、金属によって形成されているから、外部からの見た目が金属製のバックルにできる。つまり、雌部材Bを含めて、外部からの見た目の全てを金属製にできる。   In a state where the male member A is engaged with the female member B, the belt mounting portion 10 protrudes from the cylindrical body 54 of the female member B, and the operation piece 31 is exposed to the outside from the opening 58 of the female member B. The elastic arm piece 41 is accommodated in the female member B. Since the belt attachment portion 10 and the operation piece 31 of the male member A are made of metal, the external appearance can be a metal buckle. That is, all of the external appearance including the female member B can be made of metal.

雄部材Aを雌部材Bから外すには、雌部材Bの開口部58から外部の露出している操作片31を内側へ押圧する。すると、雄部材Aの弾性腕片41が内側に弾性変形される。つまり、雄部材Aのうち弾性腕片41は、弾性を有する樹脂材で形成されているから、十分な弾性変形量を確保できる。すると、雄部材Aの係合部35が雌部材Bの被係合部59から外れるから、この状態において、雄部材Aを雌部材Bから引き抜くと、雄部材Aを雌部材Bから外すことができる。
このように、弾性腕片41の弾性変形量で係合、解除操作が可能な構成である。
In order to remove the male member A from the female member B, the exposed operation piece 31 is pressed inward from the opening 58 of the female member B. Then, the elastic arm piece 41 of the male member A is elastically deformed inward. That is, since the elastic arm piece 41 of the male member A is formed of a resin material having elasticity, a sufficient amount of elastic deformation can be ensured. Then, the engaging portion 35 of the male member A is disengaged from the engaged portion 59 of the female member B. In this state, when the male member A is pulled out from the female member B, the male member A can be removed from the female member B. it can.
As described above, the engaging and releasing operations can be performed with the elastic deformation amount of the elastic arm piece 41.

また、本実施形態の雄部材Aは、樹脂のインサート成形によって一体成形できるとともに、弾性腕片41とベルト取付部10、ガイド片21および操作片31との結合が、ベルト取付部、ガイド片21および操作片31の表裏に貫通して設けられた貫通孔18,24,38に、弾性腕片41を構成する樹脂材が充填されることによって、結合されているから、これらの結合力を高めることができる。
とくに、バックルの場合、雄部材Aの差込方向および引抜方向に力を受けるが、これらの力の方向に対して略直交する方向に貫通する貫通孔18,24,38と、これに充填される樹脂材とから結合されているから、雄部材Aの差込方向および引抜方向からの力に対して十分な強度を確保できる。
In addition, the male member A of the present embodiment can be integrally formed by resin insert molding, and the coupling between the elastic arm piece 41 and the belt mounting portion 10, the guide piece 21 and the operation piece 31 is performed by the belt mounting portion and the guide piece 21. Since the through holes 18, 24 and 38 provided through the front and back of the operation piece 31 are filled with the resin material constituting the elastic arm piece 41, the bonding force is increased. be able to.
In particular, in the case of a buckle, a force is received in the insertion direction and the withdrawal direction of the male member A, but the through holes 18, 24, and 38 that pass through in a direction substantially orthogonal to the direction of these forces are filled therein. Therefore, sufficient strength can be secured against the force from the insertion direction and the drawing direction of the male member A.

<変形例>
なお、本発明は、上記実施形態で説明した構造のバックルに限定されるものでなく、次のような変形例も含む。
上記実施形態では、ベルト取付部10の両端から一対の弾性腕片41を突出させ、この各弾性腕片41の先端に操作片31を設けた構成としたが、弾性腕片41や操作片31は必ずしも一対である必要はない。ベルト取付部10から1本の弾性腕片41を突出させ、この弾性腕片41の先端に操作片31を設けるような構成でもよい。
<Modification>
In addition, this invention is not limited to the buckle of the structure demonstrated by the said embodiment, The following modifications are also included.
In the above-described embodiment, the pair of elastic arm pieces 41 protrude from both ends of the belt mounting portion 10 and the operation pieces 31 are provided at the tips of the elastic arm pieces 41. However, the elastic arm pieces 41 and the operation pieces 31 are provided. Need not necessarily be a pair. A configuration in which one elastic arm piece 41 protrudes from the belt mounting portion 10 and the operation piece 31 is provided at the tip of the elastic arm piece 41 may be adopted.

例えば、図7および図8に示す構成のバックルでもよい。図7は分解状態を示す正面図、図8は係合状態を示す正面図である。
雄部材Aは、雌部材Bに挿入される差込部20を備えている。差込部20は、ベルト取付部10から差込方向へ向かって突出する矩形片60を備える。矩形片60の内部には、操作片31を備えている。
For example, the buckle shown in FIGS. 7 and 8 may be used. 7 is a front view showing an exploded state, and FIG. 8 is a front view showing an engaged state.
The male member A includes an insertion portion 20 that is inserted into the female member B. The insertion portion 20 includes a rectangular piece 60 that protrudes from the belt attachment portion 10 in the insertion direction. An operation piece 31 is provided inside the rectangular piece 60.

操作片31と矩形片60の外周縁との間、ここでは、矩形片60の先端側縁を除く3つの外周縁と操作片31との間にはスリット61がコ字状に形成されているとともに、操作片31と矩形片60の先端側縁との間が弾性腕片41として形成れている。これにより、弾性腕片41が弾性変形することにより、操作片31が上下方向(表裏方向)へ揺動可能になっている。また、操作片31の幅方向両側部分には、雌部材Bの被係合部59と係合する係合部35が設けられている。なお、図示していないが、操作片31は、水平面に対して傾斜しており、ベルト取付部10側が先端側よりも浮き上がった状態となっている。   A slit 61 is formed in a U-shape between the operation piece 31 and the outer peripheral edge of the rectangular piece 60, here, between the three outer peripheral edges excluding the front end side edge of the rectangular piece 60 and the operation piece 31. At the same time, an elastic arm piece 41 is formed between the operation piece 31 and the front edge of the rectangular piece 60. Thereby, the elastic arm piece 41 is elastically deformed, so that the operation piece 31 can swing in the vertical direction (front and back direction). Further, engaging portions 35 that engage with the engaged portions 59 of the female member B are provided on both sides in the width direction of the operation piece 31. Although not shown, the operation piece 31 is inclined with respect to the horizontal plane, and the belt attachment portion 10 side is in a state of being lifted from the front end side.

ベルト取付部10と操作片31とは、前記実施形態と同様な金属によって形成され、これらを連結しかつ弾性腕片41を有する矩形片60の部分は、前記実施形態と同様な樹脂材で形成されている。
矩形片60の部分を構成する樹脂材は、ベルト取付部10から一体的に突出する連結部16の外面(表裏面)を覆うとともに、連結部16に表裏面に貫通形成された貫通孔18に充填される。また、樹脂材は、操作片31から一体的に突出する連結部36の外面(表裏面)を覆うとともに、連結部36に表裏面に貫通形成された貫通孔38に充填される。弾性腕片41は、連結部36から先端方向へ延びて、差込部20の外縁である矩形片60に連続して形成される。
The belt mounting portion 10 and the operation piece 31 are formed of the same metal as in the above-described embodiment, and a portion of the rectangular piece 60 that connects them and has the elastic arm piece 41 is formed of the same resin material as in the above-described embodiment. Has been.
The resin material constituting the portion of the rectangular piece 60 covers the outer surface (front and back surfaces) of the connecting portion 16 that integrally protrudes from the belt mounting portion 10, and in the through-hole 18 that is formed through the connecting portion 16 on the front and back surfaces. Filled. The resin material covers the outer surface (front and back surfaces) of the connecting portion 36 that integrally protrudes from the operation piece 31 and is filled in a through hole 38 that is formed through the connecting portion 36 on the front and back surfaces. The elastic arm piece 41 extends from the connecting portion 36 toward the distal end and is formed continuously with the rectangular piece 60 that is the outer edge of the insertion portion 20.

雌部材Bは、表面側に開口部58を有し、開口部58は差込口55と連続している。開口部58の差込口55側には被係合部59が形成されている。   The female member B has an opening 58 on the surface side, and the opening 58 is continuous with the insertion port 55. An engaged portion 59 is formed on the insertion port 55 side of the opening 58.

雄部材Aを雌部材Bに係合させるには、雄部材Aの差込部20を雌部材Bの差込口55から差し込む。このとき、差込口55の厚み寸法は、操作片31が浮き上がった状態の厚みよりも薄いため、弾性腕片41が撓むことで操作片31が差込口55を通ることができる。その後、開口部58の位置で元の状態に復帰して、係合部35が雌部材Bの被係合部59に係合する。   In order to engage the male member A with the female member B, the insertion part 20 of the male member A is inserted from the insertion port 55 of the female member B. At this time, since the thickness dimension of the insertion port 55 is thinner than the thickness in a state where the operation piece 31 is lifted, the operation piece 31 can pass through the insertion port 55 when the elastic arm piece 41 is bent. Thereafter, the state returns to the original state at the position of the opening 58, and the engaging portion 35 engages with the engaged portion 59 of the female member B.

この変形例においても、前述した実施形態と同様に、雄部材Aが雌部材Bに係合した状態では、樹脂材で形成した弾性腕片41が雌部材Bの内部に収容され、外部に露出することがないため、見た目が金属製のバックルにできる。   Also in this modified example, in the state where the male member A is engaged with the female member B, the elastic arm piece 41 formed of a resin material is accommodated inside the female member B and exposed to the outside as in the above-described embodiment. So it looks like a metal buckle.

For example, you may form with the resin material which mixed the metal powder same as the material etc. which formed the belt attachment part 10 of the male member A, and the operation piece 31, etc., or a different kind of metal powder.

上記実施形態では、金属製のガイド片21を、樹脂製のガイド片覆部43で覆ってガイド片としていたが、樹脂材のみでガイド片21を構成してもよい。つまり、無垢の樹脂材によってガイド片21を構成してもよい。   In the above-described embodiment, the metal guide piece 21 is covered with the resin guide piece covering portion 43 to form the guide piece. However, the guide piece 21 may be formed of only a resin material. That is, you may comprise the guide piece 21 with a solid resin material.

上記実施形態では、雄部材Aの係合部35が、雌部材Bの収納空間56の奥部に設けた被係合部59に係合する構造であったが、これに限らず、他の構成であってもよい。例えば、雌部材Bの開口部58に係合するように、雄部材Aの操作片31の外側に係合部を設けて、雄部材Aが雌部材Bに係合される構造であってもよい。   In the above-described embodiment, the engaging portion 35 of the male member A is configured to engage with the engaged portion 59 provided in the inner portion of the storage space 56 of the female member B. It may be a configuration. For example, even if the engaging member is provided on the outer side of the operation piece 31 of the male member A so as to engage with the opening 58 of the female member B, the male member A is engaged with the female member B. Good.

上記実施形態では、雄部材Aおよび雌部材Bにそれぞれベルト取付部としてのベルト取付孔12,57を形成したが、雌部材Bについては、ベルト取付孔がなくてもよい。つまり、雌部材Bを直接他の部材に固定するようにしてもよい。
