ところで、ライフジャケットなどの救命胴衣や、リュックサックなどの背負袋の装着品は、身体の腰部に装着されるベルトと同じく、複数の帯体を備えている。これらの帯体もまた、装着品の位置や装着品のサイズを装着者の身体に合わせるために、余剰となる部分を備えている。そして、余剰となる帯体は、装着品を利用する利用者の安全性を高める観点から、他の帯体や装着品の本体などに束ねて固定することが求められる。一方、上記装着品が使用されるシーンのなかには、例えば、片手に釣り竿を持っているフィッシング時、片手にステッキを持っている登山時などが含まれる。それゆえに、上記固定具には、片手での固定の操作、片手での解除の操作などの新たな利用のシーンに適した操作性が望まれている。 By the way, life jackets such as life jackets and backpacks such as rucksacks are equipped with a plurality of belts, similar to a belt attached to the waist of the body. These belts also have extra portions to match the position of the wearable product and the size of the wearable product to the wearer's body. Then, from the viewpoint of improving the safety of the user who uses the attached product, it is required that the surplus belt is bundled and fixed to another belt or the main body of the attached product. On the other hand, scenes in which the above-mentioned wearing items are used include, for example, fishing with a fishing rod in one hand, climbing with a walking stick in one hand, and the like. Therefore, operability suitable for a new use scene such as a fixing operation with one hand and a releasing operation with one hand is desired for the fixing tool.

本発明の目的は、操作性の拡張を可能とした樹脂製固定具を提供することである。 An object of the present invention is to provide a resin fixture capable of extending operability.

上記課題を解決するための樹脂製固定具は、一方向に延びる板状の片である基体片と、一方向に延びる板状の片である係止片と、各片の基端を連結して両片を閉状態と開状態とに切り換えるヒンジ部とを備える樹脂製固定具である。各片の短手方向が幅方向であり、前記基体片は、先端で前記一方向に突き出る幅方向に連続した爪部と、両片が対向する状態で前記爪部から前記基体片の基端に向けて徐々に前記係止片に向けて変位する傾きを有した誘導斜面とを備え、前記係止片は、閉状態で前記爪部が引っ掛かる幅方向に連続した爪受け部を備える。そして、前記誘導斜面の幅方向での長さは、前記爪部の幅方向での長さよりも短く、前記誘導斜面は、両片が閉状態へ遷移するとき、前記引っ掛かる位置まで前記爪部を誘導するように、前記爪受け部に対する前記幅方向での部分的な押圧によって、前記樹脂製固定具を変形させる。 A resin fixture for solving the above-mentioned problems is that a base piece which is a plate-like piece extending in one direction, a locking piece which is a plate-like piece extending in one direction, and a base end of each piece are connected. And a hinge part for switching both pieces between a closed state and an open state. The short side direction of each piece is the width direction, and the base piece has a claw portion that continues in the width direction at the tip and protrudes in the one direction, and a base end of the base piece from the claw portion with both pieces facing each other. And a guide slope having an inclination that gradually displaces toward the locking piece, and the locking piece includes a claw receiving portion that is continuous in a width direction in which the claw portion is hooked in the closed state. And the length in the width direction of the guide slope is shorter than the length in the width direction of the claw portion, and the guide slope has the claw portion to the position where it is caught when both pieces transition to the closed state. The resin fixture is deformed by partial pressing in the width direction against the claw receiving portion so as to be guided.

上記構成によれば、基体片と係止片とによって対象が樹脂製固定具に固定されるとき、基体片と係止片とが相互に対向し、その後、爪部が爪受け部に引っ掛かるように、ヒンジ部がさらに折り曲げられる。この際、爪受け部の幅方向での一部分を誘導斜面が押圧し、爪部が爪受け部に引っ掛かるように、樹脂製固定具が変形する。 According to the above configuration, when the object is fixed to the resin fixture by the base piece and the locking piece, the base piece and the locking piece face each other so that the nail portion is hooked on the nail receiving portion. Further, the hinge part is further bent. At this time, the resin-made fixing tool is deformed so that the guiding slope presses a part of the claw receiving portion in the width direction and the claw portion is caught by the claw receiving portion.

ここで、誘導斜面を備えない構成での操作では、幅方向に連続した爪部と、幅方向に連続した爪受け部とを直接当接させて、爪部が爪受け部に引っ掛かるように、樹脂製固定具を変形させることが求められる。この際、爪受け部に加わるべき押圧は、爪部において幅方向に分散してしまう。また、爪部と爪受け部との直接的な当接は、爪部と爪受け部との幅方向でのほぼ全体にわたる摩擦も招く。 Here, in the operation with the configuration not including the guide slope, the claw portion continuous in the width direction and the claw receiving portion continuous in the width direction are brought into direct contact so that the claw portion is hooked on the claw receiving portion. It is required to deform the resin fixture. At this time, the pressure to be applied to the nail receiving portion is dispersed in the width direction at the nail portion. Further, the direct contact between the claw portion and the claw receiving portion causes friction over almost the entire width between the claw portion and the claw receiving portion.

この点、上述したように、誘導斜面が爪受け部を部分的に押圧するという構成であれば、爪受け部に加わるべき押圧が幅方向に分散されず、また、誘導斜面と摩擦が生じる部位も、爪受け部では、幅方向での一部分で足りる。結果として、爪受け部に爪部を引っ掛けるための負荷を軽減し、樹脂製固定具に対象を固定するための操作を円滑に進めることが可能となる。そして、樹脂製固定具の操作性を拡張させることが可能ともなる。 In this regard, as described above, if the guide slope is configured to partially press the claw receiving portion, the pressure to be applied to the claw receiving portion is not dispersed in the width direction, and the portion where friction occurs with the guide slope. However, a portion in the width direction is sufficient for the nail holder. As a result, it is possible to reduce the load for hooking the claw portion on the claw receiving portion, and to smoothly proceed with the operation for fixing the target to the resin fixture. And it becomes possible to extend the operativity of a resin fixture.

なお、樹脂製固定具の閉状態においては、幅方向に連続する爪受け部に、幅方向に連続する爪部が引っ掛かる。そのため、爪部を爪受け部に係止する力、ひいては、対象を樹脂製固定具に固定する力を十分に確保することが可能ともなる。 In the closed state of the resin fixture, the claw portion continuous in the width direction is caught by the claw receiving portion continuous in the width direction. Therefore, it is possible to sufficiently secure the force for locking the claw portion to the claw receiving portion, and hence the force for fixing the object to the resin fixture.

上記樹脂製固定具において、前記基体片と前記係止片とのいずれか一方は、前記一方向での一端および他端よりも厚みが薄い反り部を前記一方向での一端と他端との間に備えてもよい。この樹脂製固定具によれば、いずれか一方の片を、反り部を起点として、一方向で反らせることが可能となる。そして、爪部を爪受け部に引っ掛けるための樹脂製固定具の変形を、いずれか一方の片での反りによって、容易に実現することが可能ともなる。 In the resin fixture, any one of the base piece and the locking piece may have a warped portion having a thickness smaller than one end and the other end in the one direction and between one end and the other end in the one direction. You may prepare in between. According to this resin fixture, any one piece can be warped in one direction starting from the warped portion. Then, the deformation of the resin fixture for hooking the claw portion onto the claw receiving portion can be easily realized by warping of one of the pieces.

上記樹脂製固定具において、前記誘導斜面は、幅方向から見て円弧状を有してもよい。この樹脂製固定具によれば、誘導斜面による爪部の誘導、すなわち、爪受け部において引っ掛かる位置まで爪部を誘導することが円滑に進められる。 In the resin fixture, the guide slope may have an arc shape when viewed from the width direction. According to this resin fixture, the guidance of the claw portion by the guiding slope, that is, the guidance of the claw portion to the position where it is caught in the claw receiving portion is smoothly advanced.

上記樹脂製固定具において、前記誘導斜面は、前記爪部の先端に接続されてもよい。この樹脂製固定具によれば、爪部の先端に誘導斜面が接続されるため、閉状態への遷移に際しては、爪部が爪受け部に引っ掛かる直前まで、誘導斜面による爪部の誘導が行われる。そのため、爪受け部に爪部を引っ掛けるための負荷をさらに軽減し、樹脂製固定具に対象を固定するための操作をさらに円滑に進めることが可能ともなる。 In the resin fixture, the guide slope may be connected to a tip of the claw portion. According to this resin fixture, since the guide slope is connected to the tip of the claw part, the guide part is guided by the guide slope until just before the claw part is caught by the claw receiving part at the time of transition to the closed state. Is called. Therefore, it is possible to further reduce the load for hooking the claw portion on the claw receiving portion, and to further smoothly perform the operation for fixing the object to the resin fixture.

上記樹脂製固定具において、前記爪受け部の縁は、前記誘導斜面を受け入れ可能な窪みを備え、前記窪みは、両片が閉状態に遷移するときに前記誘導斜面で押圧される部位であってもよい。この樹脂製固定具によれば、誘導斜面が窪みに受け入れられた状態で、誘導斜面が爪受け部の縁を押圧する。結果として、爪受け部の縁を誘導斜面が押圧するときに、爪受け部の縁と、誘導斜面との相対的な位置のずれが抑えられる。そのため、誘導斜面の押圧、ひいては、閉状態への遷移が円滑に行われる。 In the resin fixture, an edge of the claw receiving portion includes a recess that can receive the guide slope, and the recess is a portion that is pressed by the guide slope when both pieces transition to the closed state. May be. According to this resin fixture, the guide slope presses the edge of the claw receiving portion while the guide slope is received in the recess. As a result, when the guiding slope presses the edge of the nail receiving portion, a relative positional shift between the edge of the nail receiving portion and the guiding slope is suppressed. Therefore, the guide slope is smoothly pressed, and thus the transition to the closed state is smoothly performed.

上記樹脂製固定具において、前記係止片は、一方向に延びる係止本体部を備え、閉状態での前記樹脂製固定具の外側が、各片の外側であり、閉状態での前記樹脂製固定具の内側が、各片の内側であり、前記一方向において、前記基体片の長さは前記係止本体部の長さとほぼ等しく、前記誘導斜面は、前記爪部の内側に位置し、前記爪部の先端から前記爪部の基端に向けて徐々に内側に変位する傾きを有し、前記爪受け部は、前記係止本体部の端を内側で覆う半ドーム状を有し、前記爪受け部の縁と前記係止本体部の縁とが、前記係止片の基端に向く開口部を構成し、開状態から閉状態への遷移の際に、前記爪受け部の縁と前記誘導斜面とが対向し、前記爪受け部の縁に対する前記誘導斜面の押圧によって前記爪部が前記開口部内に誘導されてもよい。 In the resin fixture, the locking piece includes a locking main body extending in one direction, and the outside of the resin fixing tool in the closed state is the outside of each piece, and the resin in the closed state The inner side of the fixing fixture is the inner side of each piece. In one direction, the length of the base piece is substantially equal to the length of the locking main body portion, and the guide slope is located inside the claw portion. The claw receiving portion has a semi-dome shape that covers the end of the locking body portion on the inner side, and has an inclination that gradually displaces inward from the tip of the claw portion toward the base end of the claw portion. The edge of the claw receiving portion and the edge of the locking main body portion constitute an opening facing the proximal end of the locking piece, and when the transition from the open state to the closed state occurs, The edge and the guide slope face each other, and the claw part is guided into the opening by pressing the guide slope against the edge of the claw receiving part. Good.

上記樹脂製固定具によれば、樹脂製固定具が閉状態に遷移するとき、誘導斜面が爪受け部の縁を通過して、爪部が開口部内に入る。この際、反るように曲がっていた係止片や、誘導斜面に押圧されていた爪受け部の縁が、元の形状に戻り、形状が戻る際の振動によって音が発生する。結果として、閉状態への遷移の完了時に音が発生するため、閉状態への遷移の完了を利用者は音によって認識できる。それゆえに、暗所での利用のシーンや、片手での利用のシーンに適した操作性を樹脂製固定具に付与することが可能となる。 According to the resin fixture, when the resin fixture transitions to the closed state, the guide slope passes through the edge of the claw receiving portion, and the claw portion enters the opening. At this time, the locking piece bent so as to be warped and the edge of the claw receiving portion pressed against the guide slope return to the original shape, and sound is generated by vibration when the shape returns. As a result, since a sound is generated when the transition to the closed state is completed, the user can recognize the completion of the transition to the closed state by sound. Therefore, it is possible to impart operability suitable for a scene of use in a dark place or a scene of use with one hand to a resin fixture.

本発明によれば、樹脂製固定具の操作性を拡張することが可能となる。 According to the present invention, it is possible to extend the operability of the resin fixture.

The resin fixture is a resin product in which the base piece 10, the locking piece 20, and the hinge portion 30 are integrally formed. The hinge portion 30 connects a base end E1B that is one end of the base piece 10 and a base end E2B that is one end of the locking piece 20. The base piece 10 and the locking piece 20 have a plate shape extending in one common direction.

以下では、基体片１０および係止片２０の延びる方向が長手方向であり、長手方向と直交する方向が幅方向である。基体片１０と係止片２０とが長手方向に並ぶ状態は、樹脂製固定具の開状態であり、基体片１０と係止片２０とが相互に結合した状態は、樹脂製固定具の閉状態である。閉状態での樹脂製固定具の外表面に対する外側が、基体片１０および係止片２０の外側であり、閉状態での樹脂製固定具の外表面に対する内側が、基体片１０および係止片２０の内側である。 Hereinafter, the extending direction of the base piece 10 and the locking piece 20 is the longitudinal direction, and the direction orthogonal to the longitudinal direction is the width direction. The state in which the base piece 10 and the locking piece 20 are arranged in the longitudinal direction is an open state of the resin fixture, and the state in which the base piece 10 and the locking piece 20 are coupled to each other is the closed state of the resin fixture. State. The outer side with respect to the outer surface of the resin fixture in the closed state is the outer side of the base piece 10 and the locking piece 20, and the inner side with respect to the outer surface of the resin fixture in the closed state is the base piece 10 and the locking piece. 20 inside.

基体片１０は、基体本体部１０Ｂと係止歯１１とを備える。基体本体部１０Ｂは、長手方向に延びる板状であり、かつ、基体本体部１０Ｂの周縁を基体本体部１０Ｂの中央よりも反り上げる曲板状を有する。基体本体部１０Ｂは、閉状態での係止片２０と対向する凹曲面として基体内面１０Ｓを備える。 The base piece 10 includes a base body portion 10 B and locking teeth 11. The base body portion 10B has a plate shape extending in the longitudinal direction, and has a curved plate shape in which the periphery of the base body portion 10B is warped from the center of the base body portion 10B. The base body portion 10B includes a base inner surface 10S as a concave curved surface facing the locking piece 20 in the closed state.

係止歯１１は、基体内面１０Ｓから内側（図１の上側）に向けて立設されている。係止歯１１は、長手方向において、基体本体部１０Ｂのほぼ全体に延びる板状を有する。係止歯１１の内側端面（図１の上端面）は、長手方向に延びる波状を有している。係止歯１１の各歯先は、各歯において、係止歯１１の長手方向のほぼ中央に偏っている。 The locking teeth 11 are erected from the inner surface 10S of the base toward the inside (upper side in FIG. 1). The locking teeth 11 have a plate shape extending in substantially the entire base body portion 10B in the longitudinal direction. The inner end surface (upper end surface in FIG. 1) of the locking tooth 11 has a wave shape extending in the longitudinal direction. Each tooth tip of the locking tooth 11 is biased to substantially the center in the longitudinal direction of the locking tooth 11 in each tooth.

基体片１０の他端部である先端Ｅ１Ｔは、長手方向に突き出る爪部１３と、爪部１３から基体内面１０Ｓにわたり立設された爪誘導部１２とを備える。爪部１３は、基体片１０の先端Ｅ１Ｔから外側（図１の下側）に湾曲するフック状の断面を幅方向に連続させている。爪部１３は、閉状態において係止片２０に引っ掛かる。 The tip E1T which is the other end portion of the base piece 10 includes a claw portion 13 protruding in the longitudinal direction and a claw guide portion 12 erected from the claw portion 13 to the base inner surface 10S. The claw portion 13 has a hook-shaped cross section that curves outward (lower side in FIG. 1) from the tip E1T of the base piece 10 and continues in the width direction. The claw portion 13 is hooked on the locking piece 20 in the closed state.

爪誘導部１２は、係止歯１１よりも先端Ｅ１Ｔの側に位置し、かつ、爪部１３の内側（図１の上側）に位置する。爪誘導部１２は、係止歯１１と連なるように、係止歯１１から先端Ｅ１Ｔまで長手方向に延びる。爪誘導部１２の内側端面（図１の上端面）は、誘導斜面１２Ｓ（図２参照）である。誘導斜面１２Ｓは、緩やかな曲面であり、先端Ｅ１Ｔから基端Ｅ１Ｂに向けて徐々に内側（図１の上側）に変位する傾きを有する。 The nail guide part 12 is located on the tip E1T side of the locking tooth 11 and is located on the inner side of the claw part 13 (upper side in FIG. 1). The claw guide portion 12 extends in the longitudinal direction from the locking tooth 11 to the tip E1T so as to be continuous with the locking tooth 11. An inner end face (upper end face in FIG. 1) of the nail guide portion 12 is a guide slope 12S (see FIG. 2). The guide slope 12S is a gentle curved surface and has an inclination that gradually displaces inward (upper side in FIG. 1) from the distal end E1T toward the proximal end E1B.

係止片２０は、係止本体部２０Ｂと爪受け部２４とを備える。係止本体部２０Ｂは、長手方向に延びる板状であり、かつ、基体本体部１０Ｂと同じく、係止本体部２０Ｂの周縁が係止本体部２０Ｂの中央よりも反り上がる曲板状を有する。係止本体部２０Ｂは、閉状態での基体片１０と対向する凹曲面として係止内面２０Ｓを備える。 The locking piece 20 includes a locking main body portion 20 B and a claw receiving portion 24. The locking main body portion 20B has a plate shape extending in the longitudinal direction, and has a curved plate shape in which the peripheral edge of the locking main body portion 20B warps from the center of the locking main body portion 20B, like the base body main body portion 10B. The locking main body portion 20B includes a locking inner surface 20S as a concave curved surface facing the base piece 10 in the closed state.

係止本体部２０Ｂは、長手方向のほぼ中央に反り部２１を備える。反り部２１の幅方向の長さは、係止本体部２０Ｂのなかで、反り部２１以外の他の部位よりも小さい。係止片２０は、反り部２１を起点として反りやすい形状を有する。また、係止片２０は、長手方向のほぼ中央に、長手方向に延びる貫通孔２２を備える。貫通孔２２は、幅方向における反り部２１の厚みを、係止片２０の基端Ｅ２Ｂや先端Ｅ２Ｔよりも薄くし、それによって、反り部２１を起点として係止片２０をさらに反りやすくする。なお、反り部２１の位置する範囲は、係止片２０の長手方向の長さを１００％としたとき、係止片２０の長手方向の中央から長手方向の両方向にそれぞれ２０％以内であることが好ましい。 The locking main body portion 20B includes a warped portion 21 at substantially the center in the longitudinal direction. The length of the warped portion 21 in the width direction is smaller than other portions other than the warped portion 21 in the locking main body portion 20B. The locking piece 20 has a shape that tends to warp starting from the warped portion 21. The locking piece 20 includes a through-hole 22 extending in the longitudinal direction substantially at the center in the longitudinal direction. The through hole 22 makes the thickness of the warped portion 21 in the width direction thinner than the base end E2B and the distal end E2T of the locking piece 20, thereby making the locking piece 20 more easily warped starting from the warped portion 21. The range in which the warped portion 21 is located is within 20% in each of the longitudinal direction from the center in the longitudinal direction of the locking piece 20 when the length in the longitudinal direction of the locking piece 20 is 100%. Is preferred.

係止本体部２０Ｂは、係止内面２０Ｓの先端Ｅ２Ｔの側に、係止本体部２０Ｂの内側から外側まで（図１の上側から下側まで）を貫通する発音孔２３を備える。発音孔２３は、幅方向において、係止本体部２０Ｂのほぼ全体にわたり、爪受け部２４によって覆われている。 The locking main body portion 20B includes a sound generation hole 23 penetrating from the inner side to the outer side (from the upper side to the lower side in FIG. 1) of the locking main body portion 20B on the distal end E2T side of the locking inner surface 20S. The sound generation hole 23 is covered with the claw receiving portion 24 over substantially the entire locking main body portion 20B in the width direction.

爪受け部２４は、係止本体部２０Ｂの周縁のなかで、係止本体部２０Ｂの一端における縁と連結した半ドーム状を有する。係止内面２０Ｓと対向する方向から見て、爪受け部２４は、発音孔２３の一部を覆う。爪受け部２４における基端Ｅ２Ｂ側の縁２４Ｅと、係止内面２０Ｓにおける先端Ｅ２Ｔ側の縁とは、係止片２０の基端Ｅ２Ｂに向く開口部を構成する。幅方向において、爪受け部２４の縁２４Ｅの有する長さは、爪部１３の有する長さとほぼ等しい。爪受け部２４の縁２４Ｅは、閉状態への遷移において、爪部１３が開口部に入ること、および、爪部１３の先端が爪受け部２４の縁２４Ｅに引っ掛かることを可能としている。 The claw receiving portion 24 has a semi-dome shape connected to an edge at one end of the locking main body portion 20B in the periphery of the locking main body portion 20B. When viewed from the direction facing the locking inner surface 20 S, the claw receiving portion 24 covers a part of the sound generation hole 23. The edge 24E on the base end E2B side of the claw receiving portion 24 and the edge on the front end E2T side of the locking inner surface 20S constitute an opening facing the base end E2B of the locking piece 20. In the width direction, the length of the edge 24E of the claw receiving portion 24 is substantially equal to the length of the claw portion 13. The edge 24E of the claw receiving portion 24 enables the claw portion 13 to enter the opening and the tip of the claw portion 13 to be caught on the edge 24E of the claw receiving portion 24 in the transition to the closed state.

爪受け部２４の内側面（図１の上面）は、複数の突起２５を備える。各突起２５は、段差部の一例であり、樹脂製固定具を利用する利用者が各突起２５の存在を触覚で認識可能な段差を有する。複数の突起２５は、係止片２０のなかの爪受け部２４の位置を触覚によって利用者に認識させる。 The inner side surface (upper surface in FIG. 1) of the claw receiving portion 24 includes a plurality of protrusions 25. Each protrusion 25 is an example of a stepped portion, and has a step that allows a user who uses a resin fixture to recognize the presence of each protrusion 25 by touch. The plurality of protrusions 25 allows the user to recognize the position of the claw receiving portion 24 in the locking piece 20 by touch.

爪受け部２４の縁２４Ｅは、爪誘導部１２の誘導斜面１２Ｓを受け入れ可能な窪み２６を備える。窪み２６の深さは、爪受け部２４の縁２４Ｅから先端Ｅ２Ｔに向けて徐々に浅くなる。閉状態への遷移において、窪み２６は、窪み２６への爪誘導部１２の進入を促し、爪誘導部１２の誘導斜面１２Ｓと、爪受け部２４の縁２４Ｅとの相対的な位置のずれを抑える。 The edge 24 E of the claw receiving portion 24 includes a recess 26 that can receive the guiding slope 12 S of the claw guiding portion 12. The depth of the recess 26 gradually decreases from the edge 24E of the claw receiving portion 24 toward the tip E2T. In the transition to the closed state, the recess 26 urges the nail guide portion 12 to enter the recess 26, and shifts the relative position between the guide slope 12 S of the nail guide portion 12 and the edge 24 E of the nail receiving portion 24. suppress.

図２が示すように、爪誘導部１２は、爪部１３の幅方向でのほぼ中央に位置する。爪誘導部１２は、幅方向から見て扇板状を有し、誘導斜面１２Ｓは、幅方向から見て円弧状を有する。爪部１３の長手方向での先端もまた、幅方向から見て円弧状を有する。誘導斜面１２Ｓは、爪部１３の長手方向での先端に接続される。爪部１３に対する誘導斜面１２Ｓの高さの変化は、爪部１３の長手方向での先端に近い部位ほど急峻である。誘導斜面１２Ｓにおいて最も内側に位置する部位は、内側端１２Ｐであり、内側端１２Ｐは、爪部１３よりも基体片１０の基端Ｅ１Ｂ側に位置する。 As shown in FIG. 2, the nail guide portion 12 is located substantially at the center of the claw portion 13 in the width direction. The claw guide portion 12 has a fan shape when viewed from the width direction, and the guide slope 12S has an arc shape when viewed from the width direction. The front end of the claw portion 13 in the longitudinal direction also has an arc shape when viewed from the width direction. The guide slope 12S is connected to the tip of the claw portion 13 in the longitudinal direction. The change in the height of the guide slope 12S with respect to the claw portion 13 is steeper as the portion is closer to the tip in the longitudinal direction of the claw portion 13. The innermost portion of the guiding slope 12S is the inner end 12P, and the inner end 12P is located closer to the base end E1B of the base piece 10 than the claw portion 13 is.

爪誘導部１２は、爪部１３と一体であり、係止歯１１の幅方向での長さＷ１１は、誘導斜面１２Ｓの幅方向での長さＷ１２とほぼ等しく、爪部１３の幅方向での長さよりも短い。誘導斜面１２Ｓは、樹脂製固定具の閉状態への遷移に際して、爪受け部２４を押圧する部分である。爪誘導部１２と爪部１３とが一体となる構成であれば、爪部１３の幅方向の長さよりも長さＷ１２が短いとは言え、爪受け部２４を押圧するに足る強度を爪誘導部１２で確保することが容易ともなる。 The claw guide portion 12 is integral with the claw portion 13, and the length W11 in the width direction of the locking teeth 11 is substantially equal to the length W12 in the width direction of the guide slope 12S, and in the width direction of the claw portion 13. Shorter than the length of. The guide slope 12S is a portion that presses the claw receiving portion 24 when the resin fixture is shifted to the closed state. If the nail guide portion 12 and the nail portion 13 are integrated, the nail guide has sufficient strength to press the nail receiving portion 24 although the length W12 is shorter than the length in the width direction of the nail portion 13. It becomes easy to secure by the part 12.

図３が示すように、基体片１０の先端Ｅ１Ｔにおける外面（図３の下面）は、複数の突起１４を備える。複数の突起１４は、段差部の一例であり、突起２５と同じく、樹脂製固定具を利用する利用者が突起２５の存在を触覚で認識可能な段差を有する。複数の突起１４は、基体片１０のなかの先端Ｅ１Ｔの位置、特に、基体片１０のなかの爪部１３の位置を触覚によって利用者に認識させる。また、複数の突起１４は、閉状態への遷移において、利用者の指などの基体片１０の外面での滑りを抑える。 As shown in FIG. 3, the outer surface (the lower surface in FIG. 3) at the tip E 1 T of the base piece 10 includes a plurality of protrusions 14. The plurality of protrusions 14 is an example of a stepped portion, and, like the protrusion 25, has a step that allows a user using a resin fixture to recognize the presence of the protrusion 25 by touch. The plurality of protrusions 14 allows the user to recognize the position of the tip E1T in the base piece 10, in particular, the position of the claw portion 13 in the base piece 10 by touch. Further, the plurality of protrusions 14 suppress slipping on the outer surface of the base piece 10 such as a user's finger in the transition to the closed state.

係止本体部２０Ｂの外面（図３の下面）は、貫通孔２２よりも基端Ｅ２Ｂの側に、表示部２７を備える。表示部２７は、樹脂製固定具の製品名や、樹脂製固定具の製品番号などの表示に用いられる。なお、反り部２１の位置する範囲、すなわち、貫通孔２２の位置する範囲が、上述した好ましい範囲内であれば、表示部２７の大きさを係止本体部２０Ｂの外面で十分に確保することが可能ともなる。 The outer surface (the lower surface in FIG. 3) of the locking main body 20 B includes a display unit 27 on the proximal end E 2 B side with respect to the through hole 22. The display unit 27 is used to display the product name of the resin fixture, the product number of the resin fixture, and the like. In addition, if the range in which the warped portion 21 is located, that is, the range in which the through hole 22 is located is within the above-described preferable range, the size of the display portion 27 should be sufficiently secured on the outer surface of the locking main body portion 20B. Is also possible.

係止本体部２０Ｂの外面は、貫通孔２２よりも先端Ｅ２Ｔ側に、複数の突起２８を備える。複数の突起２８は、段差部の一例であり、突起１４，２５と同じく、樹脂製固定具を利用する利用者が突起２８の存在を触覚で認識可能な段差を有する。複数の突起２８は、係止本体部２０Ｂの先端Ｅ２Ｔの位置、特に、閉状態において突起１４と対向する位置を触覚によって利用者に認識させる。複数の突起２８は、閉状態への遷移において、利用者の指などの係止片２０の外面での滑りを抑える。 The outer surface of the locking main body 20B includes a plurality of protrusions 28 on the tip E2T side of the through hole 22. The plurality of protrusions 28 are an example of stepped portions, and, like the protrusions 14 and 25, have a step that allows a user using a resin fixture to recognize the presence of the protrusions 28 by touch. The plurality of protrusions 28 allows the user to recognize the position of the tip E2T of the locking main body 20B, in particular, the position facing the protrusion 14 in the closed state, by tactile sense. The plurality of protrusions 28 suppress slipping on the outer surface of the locking piece 20 such as a user's finger in the transition to the closed state.

発音孔２３の内部には、爪受け部２４から外側（図３の下側）に向けて区画壁２９が立設されている。幅方向において、区画壁２９は、発音孔２３の全体にわたり位置する。区画壁２９は、１つの発音孔２３を、基端Ｅ２Ｂの側の空間Ｓ１と、先端Ｅ２Ｔの側の空間Ｓ２とに区画する。空間Ｓ１は、閉状態において爪部１３を入れるための空間であり、閉状態での爪部１３を長手方向で位置決めするための空間でもある。空間Ｓ２は、発音孔２３のなかの空間Ｓ１以外の空間であり、例えば、可聴域の音を発音孔２３で増幅させるため機能を備えてもよい。すなわち、長手方向における区画壁２９の位置は、可聴域の音を発音孔２３にて共鳴させる位置であることが好ましい。 A partition wall 29 is erected in the sound generation hole 23 from the claw receiving portion 24 toward the outside (the lower side in FIG. 3). In the width direction, the partition wall 29 is located over the entire sound generation hole 23. The partition wall 29 partitions one sound generation hole 23 into a space S1 on the proximal end E2B side and a space S2 on the distal end E2T side. The space S1 is a space for inserting the claw portion 13 in the closed state, and is also a space for positioning the claw portion 13 in the closed state in the longitudinal direction. The space S 2 is a space other than the space S 1 in the sound generation hole 23. For example, the space S 2 may have a function for amplifying sound in the audible range through the sound generation hole 23. That is, the position of the partition wall 29 in the longitudinal direction is preferably a position where the sound in the audible range is resonated by the sound generation hole 23.

図４が示すように、長手方向において、ヒンジ部３０と爪部１３との距離は、被係止距離Ｌ１１である。長手方向において、爪誘導部１２の内側端１２Ｐ（図４の上端）とヒンジ部３０との距離は、誘導距離Ｌ１２である。長手方向において、爪受け部２４の縁２４Ｅとヒンジ部３０との距離は、係止距離Ｌ２１である。 As shown in FIG. 4, in the longitudinal direction, the distance between the hinge part 30 and the claw part 13 is a locked distance L11. In the longitudinal direction, the distance between the inner end 12P (upper end in FIG. 4) of the nail guide portion 12 and the hinge portion 30 is a guide distance L12. In the longitudinal direction, the distance between the edge 24E of the claw receiving portion 24 and the hinge portion 30 is a locking distance L21.

被係止距離Ｌ１１は、係止距離Ｌ２１よりも長く、それによって、閉状態では、爪部１３が爪受け部２４に引っ掛かることが可能となる。誘導距離Ｌ１２は、被係止距離Ｌ１１よりも短く、かつ、係止距離Ｌ２１よりも長い。それによって、閉状態への遷移では、爪誘導部１２の誘導斜面１２Ｓが、爪受け部２４の縁２４Ｅを押圧し、かつ、誘導斜面１２Ｓの傾斜に追従して爪誘導部１２が爪受け部２４の縁２４Ｅを滑るように、爪部１３が開口部内に近づくことが可能となる。 The locked distance L11 is longer than the locking distance L21, so that the claw portion 13 can be hooked on the claw receiving portion 24 in the closed state. The guiding distance L12 is shorter than the locked distance L11 and longer than the locking distance L21. Thereby, in the transition to the closed state, the guide slope 12S of the nail guide 12 presses the edge 24E of the nail receiver 24, and the nail guide 12 follows the slope of the guide slope 12S. Thus, the claw portion 13 can approach the opening so as to slide along the 24 edge 24E.

図５が示すように、ヒンジ部３０は、折り曲げ部３１と連結部３２とから構成される。折り曲げ部３１の厚みＷＴは、連結部３２の厚みよりも薄い。長手方向において、折り曲げ部３１の長さＷＨは、ヒンジ部３０の長さＷＬから長さＷＨを差し引いた長さ、すなわち、連結部３２の長さよりも短い。 As shown in FIG. 5, the hinge part 30 includes a bent part 31 and a connecting part 32. The thickness WT of the bent portion 31 is thinner than the thickness of the connecting portion 32. In the longitudinal direction, the length WH of the bent portion 31 is shorter than the length WL of the hinge portion 30 minus the length WH, that is, the length of the connecting portion 32.

ヒンジ部３０は、ヒンジ部３０のなかで長手方向の長さが短い折り曲げ部３１を別途備えるため、閉状態への遷移において、折れ曲がる部位が長手方向でばらつくことを抑える。折れ曲がる部位の長手方向のばらつきは、被係止距離Ｌ１１、誘導距離Ｌ１２、および、係止距離Ｌ２１のばらつきを招く。この点、ヒンジ部３０が別途折り曲げ部３１を備える構成であれば、これらの距離のばらつきを抑えること、ひいては、爪誘導部１２と爪受け部２４の縁２４Ｅとの相関による爪部１３の誘導の再現性を高めることが可能ともなる。また、ヒンジ部３０の曲げによる変性が、厚みの薄い折り曲げ部３１で生じるため、折り曲げ部３１の厚みが厚い構成と比べて、ヒンジ部３０における色味の変化を抑えることが可能ともなる。 Since the hinge part 30 is additionally provided with a bent part 31 having a short length in the longitudinal direction in the hinge part 30, it is possible to prevent the bent part from varying in the longitudinal direction during the transition to the closed state. Variations in the longitudinal direction of the bent portions cause variations in the locked distance L11, the guiding distance L12, and the locking distance L21. In this regard, if the hinge portion 30 includes a separate bent portion 31, it is possible to suppress variations in these distances, and thus to guide the nail portion 13 by the correlation between the nail guiding portion 12 and the edge 24E of the nail receiving portion 24. It becomes possible to improve the reproducibility of. Moreover, since the modification | denaturation by bending of the hinge part 30 arises in the bending part 31 with thin thickness, compared with the structure where the thickness of the bending part 31 is thick, it also becomes possible to suppress the color change in the hinge part 30.

［作用］
図６が示すように、樹脂製固定具が対象を固定する場合、まず、開状態の樹脂製固定具において、基体片１０の突起１４が親指で押さえられ、係止片２０の突起２８が人差し指で押さえられ、それによって、ヒンジ部３０が開状態から閉状態に向けて遷移しはじめる。この間に、基体片１０と係止片２０との間には、対象が配置される。そして、基体片１０と係止片２０とによる対象の挟み込みが進むと、爪誘導部１２の誘導斜面１２Ｓが爪受け部２４の窪み２６に入り込み、爪誘導部１２の誘導斜面１２Ｓが爪受け部２４の縁２４Ｅにおける一部分を押圧しはじめる。 [Action]
As shown in FIG. 6, when the resin fixture fixes the object, first, in the opened resin fixture, the projection 14 of the base piece 10 is pressed by the thumb, and the projection 28 of the locking piece 20 is the index finger. As a result, the hinge part 30 starts to transition from the open state to the closed state. During this time, the object is disposed between the base piece 10 and the locking piece 20. Then, when the object piece is sandwiched between the base piece 10 and the locking piece 20, the guide slope 12S of the nail guide 12 enters the recess 26 of the nail receiver 24, and the guide slope 12S of the nail guide 12 is the nail holder. It begins to press a part of the 24 edge 24E.

この際、爪受け部２４の縁２４Ｅにおいて、窪み２６は窪み２６への爪誘導部１２の進入を促し、かつ、爪誘導部１２の誘導斜面１２Ｓと爪受け部２４の縁２４Ｅとの相対的な位置のずれを抑える。また、爪誘導部１２の誘導斜面１２Ｓによって押圧される爪受け部２４は、図中上側に向けて反るように変形し、また、押圧の反力を受ける係止片２０は、反り部２１を起点として図中上側に向けて反るように変形する。そして、爪誘導部１２の誘導斜面１２Ｓが備える傾斜に従って、係止内面２０Ｓに向けた爪誘導部１２の接近が円滑に進む。 At this time, at the edge 24E of the nail receiving portion 24, the recess 26 prompts the nail guiding portion 12 to enter the recess 26, and the guide slope 12S of the nail guiding portion 12 and the edge 24E of the nail receiving portion 24 are relative to each other. To prevent misalignment. Further, the claw receiving portion 24 pressed by the guide slope 12S of the claw guiding portion 12 is deformed so as to warp upward in the figure, and the locking piece 20 receiving the reaction force of the pressing is the warped portion 21. It is deformed so as to warp upward in the figure starting from. And the approach of the nail | claw guide | induction part 12 toward the latching inner surface 20S advances smoothly according to the inclination with which the guidance | inclination slope 12S of the nail | claw guidance | induction part 12 is equipped.

ここで、爪誘導部１２を備えない構成での閉状態への遷移では、幅方向に連続した爪部１３と、幅方向に連続した爪受け部２４とを直接当接させて、爪部１３が爪受け部２４に引っ掛かるように、樹脂製固定具を変形させることが求められる。この際、爪受け部２４に加わるべき押圧は、爪部１３において幅方向に分散してしまう。また、爪部１３と爪受け部２４との直接的な当接は、爪部１３と爪受け部２４との幅方向でのほぼ全体にわたる摩擦も招く。 Here, in the transition to the closed state in the configuration without the nail guide portion 12, the claw portion 13 that is continuous in the width direction and the claw receiving portion 24 that is continuous in the width direction are brought into direct contact with each other, thereby It is required to deform the resin fixture so that the hook is caught by the claw receiving portion 24. At this time, the pressure to be applied to the claw receiving portion 24 is dispersed in the width direction in the claw portion 13. Further, the direct contact between the claw portion 13 and the claw receiving portion 24 causes friction over almost the entire width of the claw portion 13 and the claw receiving portion 24.

この点、上述した誘導斜面１２Ｓが、爪受け部２４の縁２４Ｅを部分的に押圧する構成であれば、爪受け部２４に加わるべき押圧が幅方向に分散されず、また、誘導斜面１２Ｓと摩擦が生じる部位も、爪受け部２４では、幅方向での一部分である窪み２６で足りる。結果として、爪受け部２４に爪部１３を引っ掛けるための負荷を軽減し、樹脂製固定具に対象を固定するための操作を円滑に進めることが可能となる。 In this regard, if the above-described guiding slope 12S is configured to partially press the edge 24E of the claw receiving portion 24, the pressure to be applied to the claw receiving portion 24 is not dispersed in the width direction, and the guiding slope 12S and In the claw receiving portion 24, the recess 26 which is a part in the width direction is sufficient for the portion where the friction occurs. As a result, it is possible to reduce the load for hooking the claw portion 13 on the claw receiving portion 24 and smoothly advance the operation for fixing the object to the resin fixture.

図７が示すように、爪受け部２４の縁２４Ｅと、係止内面２０Ｓの先端Ｅ２Ｔ側の縁とによって開口部が構成され、爪誘導部１２の誘導斜面１２Ｓがその開口部を通過すると、基体内面１０Ｓと係止内面２０Ｓとが結合する閉状態に遷移する。そして、爪部１３は開口部内に進入して空間Ｓ１に収容され、爪部１３の爪端１３Ｅが、爪受け部２４の縁２４Ｅに引っ掛かる。そして、樹脂製固定具の閉状態においては、幅方向に連続する爪受け部２４に、幅方向に連続する爪部１３が引っ掛かるため、爪部１３を爪受け部２４に係止する力、ひいては、対象を樹脂製固定具に固定するための力を十分に確保することが可能ともなる。 As shown in FIG. 7, an opening is constituted by the edge 24E of the claw receiving portion 24 and the edge on the tip E2T side of the locking inner surface 20S, and when the guiding slope 12S of the claw guiding portion 12 passes through the opening, A transition is made to the closed state in which the base inner surface 10S and the locking inner surface 20S are coupled. And the nail | claw part 13 approachs in an opening part, and is accommodated in space S1, and the nail | claw end 13E of the nail | claw part 13 is hooked on the edge 24E of the nail | claw receiving part 24. FIG. In the closed state of the resin fixture, the claw portion 13 that is continuous in the width direction is hooked on the claw receiving portion 24 that is continuous in the width direction. In addition, it is possible to sufficiently secure a force for fixing the object to the resin fixture.

この際、反るように曲がっていた係止片２０や、誘導斜面１２Ｓに押圧されていた爪受け部２４の縁２４Ｅが、元の形状に戻り、形状が戻る際の振動によって発音孔２３で音が発生する。この間、複数の突起１４，２８は、閉状態への遷移において、基体片１０の外面や係止片２０の外面で利用者の指が滑ることを抑える。 At this time, the locking piece 20 bent so as to warp and the edge 24E of the claw receiving portion 24 pressed against the guide slope 12S return to the original shape, and the sound generation hole 23 is caused by vibration when the shape returns. Sound is generated. During this time, the plurality of protrusions 14 and 28 prevent the user's finger from slipping on the outer surface of the base piece 10 and the outer surface of the locking piece 20 in the transition to the closed state.

なお、閉状態から開状態への遷移に際しては、まず、閉状態の樹脂製固定具において、係止片２０の突起２８が人差し指で押さえられ、係止片２０の突起２５が親指で押さえられる。そして、爪受け部２４を係止本体部２０Ｂに向けて反らせる外力が爪受け部２４に作用し、それによって、爪部１３の爪端１３Ｅによる引っ掛かりが解除され、樹脂製固定具が開状態に遷移する。 In the transition from the closed state to the open state, first, in the resin fixture in the closed state, the protrusion 28 of the locking piece 20 is pressed with the index finger, and the protrusion 25 of the locking piece 20 is pressed with the thumb. Then, an external force that warps the claw receiving portion 24 toward the locking main body portion 20B acts on the claw receiving portion 24, thereby releasing the catch by the claw end 13E of the claw portion 13 and opening the resin fixture. Transition.

以上、上記実施形態によれば、以下の効果が得られる。
（１）閉状態への遷移に際して、爪受け部２４に加わるべき押圧は、幅方向に分散されず、また、誘導斜面１２Ｓと摩擦が生じる部位も、爪受け部２４では、幅方向での一部分である窪み２６で足りる。結果として、爪受け部２４に爪部１３を引っ掛けるための負荷を軽減し、樹脂製固定具に対象を固定するための操作を円滑に進めることが可能となる。そして、樹脂製固定具の操作性を拡張させることが可能ともなる。 As mentioned above, according to the said embodiment, the following effects are acquired.
(1) During the transition to the closed state, the pressure to be applied to the claw receiving portion 24 is not dispersed in the width direction, and a portion where friction occurs with the guide slope 12S is also a part of the claw receiving portion 24 in the width direction. The recess 26 is sufficient. As a result, it is possible to reduce the load for hooking the claw portion 13 on the claw receiving portion 24 and smoothly advance the operation for fixing the object to the resin fixture. And it becomes possible to extend the operativity of a resin fixture.

（２）幅方向に連続する爪部１３が、幅方向に連続する爪受け部２４に引っ掛かるため、対象を樹脂製固定具に固定するための力を十分に確保することが可能ともなる。
（３）係止片２０が反り部２１を備えるため、閉状態への遷移に際しては、係止片２０が反り部２１を起点として反りやすい。それゆえに、爪部１３を爪受け部２４に引っ掛けるための樹脂製固定具の変形を、係止片２０での反りによって、容易に実現することが可能ともなる。 (2) Since the claw portion 13 that is continuous in the width direction is caught by the claw receiving portion 24 that is continuous in the width direction, it is possible to sufficiently secure a force for fixing the object to the resin fixture.
(3) Since the locking piece 20 includes the warped portion 21, the locking piece 20 tends to warp starting from the warped portion 21 during the transition to the closed state. Therefore, the deformation of the resin fixture for hooking the claw portion 13 on the claw receiving portion 24 can be easily realized by warping at the locking piece 20.

（４）誘導斜面１２Ｓが幅方向から見て円弧状を有するため、誘導斜面１２Ｓによる爪部１３の誘導、すなわち、爪受け部２４において引っ掛かる位置まで爪部１３を誘導することが円滑に進められる。 (4) Since the guide slope 12S has an arc shape when viewed from the width direction, the guide claw 13 is guided by the guide slope 12S, that is, the claw part 13 is smoothly guided to the position where it is caught in the nail receiving part 24. .

（５）爪部１３の先端に誘導斜面１２Ｓが接続されるため、閉状態への遷移に際しては、爪部１３が爪受け部２４に引っ掛かる直前まで、誘導斜面１２Ｓによる爪部１３の誘導が行われる。そのため、爪受け部２４に爪部１３を引っ掛けるための負荷をさらに軽減し、樹脂製固定具に対象を固定するための操作をさらに円滑に進めることが可能ともなる。 (5) Since the guiding inclined surface 12S is connected to the tip of the claw portion 13, the guiding inclined surface 12S guides the claw portion 13 until the claw portion 13 is hooked on the claw receiving portion 24 at the time of transition to the closed state. Is called. Therefore, it is possible to further reduce the load for hooking the claw portion 13 on the claw receiving portion 24 and further smoothly perform the operation for fixing the object to the resin fixture.

（６）爪部１３に対する誘導斜面１２Ｓの高さの変化は、爪部１３の長手方向での先端に近い部位ほど急峻である。そのため、閉状態への遷移に際しては、爪部１３の先端と爪受け部２４の縁２４Ｅとの距離が短くなるほど、これらの近付く速度が高まる。結果として、閉状態への遷移の完了時に発生する音をより高めることが可能となる。 (6) The change in the height of the guide slope 12S with respect to the claw portion 13 is steeper as the portion is closer to the tip in the longitudinal direction of the claw portion 13. Therefore, at the time of transition to the closed state, the approaching speed increases as the distance between the tip of the claw part 13 and the edge 24E of the claw receiving part 24 becomes shorter. As a result, it is possible to further increase the sound generated when the transition to the closed state is completed.

（７）爪受け部２４の縁２４Ｅを誘導斜面１２Ｓが押圧するときに、爪受け部２４の縁２４Ｅと、誘導斜面１２Ｓとの相対的な位置のずれを、誘導斜面１２Ｓを受け入れる窪み２６が抑える。そのため、誘導斜面１２Ｓの押圧による樹脂製固定具の変形、ひいては、開状態から閉状態への遷移が円滑に行われる。 (7) When the guide slope 12S presses the edge 24E of the claw receiving portion 24, the recess 26 that receives the guide slope 12S is displaced relative to the edge 24E of the claw support portion 24 and the guide slope 12S. suppress. Therefore, the deformation of the resin fixture due to the pressing of the guide slope 12S, and the transition from the open state to the closed state is smoothly performed.

（８）閉状態への遷移の完了時に音が発生するため、閉状態への遷移の完了を利用者は音によって認識できる。それゆえに、暗所での利用のシーンや、片手での利用のシーンに適した操作性を樹脂製固定具に付与することが可能となる。 (8) Since a sound is generated when the transition to the closed state is completed, the user can recognize the completion of the transition to the closed state by sound. Therefore, it is possible to impart operability suitable for a scene of use in a dark place or a scene of use with one hand to a resin fixture.

（９）係止本体部２０Ｂの発音孔２３を半ドーム状の爪受け部２４が覆うため、閉状態への遷移の完了時に発生する音が共鳴によって増幅される。結果として、それゆえに、暗所での利用のシーンにさらに適した操作性を樹脂製固定具に付与することが可能となる。 (9) Since the half-dome-shaped claw receiving portion 24 covers the sound generation hole 23 of the locking main body portion 20B, the sound generated when the transition to the closed state is completed is amplified by resonance. As a result, therefore, it becomes possible to impart operability more suitable for a scene of use in a dark place to the resin fixture.

（１０）基体片１０の内面と外面との差異、および、係止片２０の内面と外面との差異、さらには、基体片１０の先端Ｅ１Ｔや係止片２０の先端Ｅ２Ｔの位置を、突起１４，２５，２８に触れる利用者は、触覚で認識することが可能ともなる。そのため、視界が良好ではないシーンでの対象の固定操作や固定の解除操作が円滑に行われる。 (10) The difference between the inner surface and the outer surface of the base piece 10, the difference between the inner surface and the outer face of the locking piece 20, and the position of the tip E1T of the base piece 10 and the tip E2T of the locking piece 20 are projected. The user who touches 14, 25, 28 can also recognize by touch. For this reason, the target fixing operation and the fixing release operation are smoothly performed in a scene with poor visibility.

なお、上記実施形態は以下のように変更して実施することも可能である。
［樹脂製固定具］
・樹脂製固定具を構成する樹脂は、例えば、ポリプロピレン、ポリプロピレンとポリエチレンとの混合物、ポリプロピレンとエラストマーとの混合物である。ポリプロピレンとポリエチレンとの混合物は、例えば、混合物の重量に対するポリプロピレンの重量の比が５０％以上であることが好ましい。 In addition, the said embodiment can also be changed and implemented as follows.
[Resin fixture]
The resin constituting the resin fixture is, for example, polypropylene, a mixture of polypropylene and polyethylene, or a mixture of polypropylene and elastomer. In the mixture of polypropylene and polyethylene, for example, the ratio of the weight of polypropylene to the weight of the mixture is preferably 50% or more.
