Further, when the fixed portion 20 is attached to the attachment portion 10, the first distance D1 is larger than the second distance D2, so that the fixed portion 20 is more difficult to come off from the attachment portion 10.

次に、図４を参照して固定部２０を取付け部１０に取り付ける手順を説明する。図４（ａ）に示すように、固定部２０の接続部２４に何も外力が加えられていない状態では、接続部２４は第一距離Ｄ１が第二距離Ｄ２よりも大きい状態を維持している。この状態から、図４（ｂ）に示すように、一対の挿入部２２を取付け穴部１４の開口１６の位置にあわせる。そして、図４（ｂ）の二点鎖線で示すように、接続部２４に外力を加えて、第一距離Ｄ１が第二距離Ｄ２よりも小さくなるように一対の挿入部２２を互いに近接させる。具体的には、接続部２４の第一連結部２８Ａおよび第二連結部２８Ｂが互いに近接するように押し狭める。これによって、第一挿入部２２Ａの第一端２２Ａａと第二挿入部２２Ｂの第一端２２Ｂａとが互いに近接する。この状態で、一対の挿入部２２を第一取付け穴部１４Ａの開口１６ｂと第二取付け穴部１４Ｂの開口１６ｃとの間に配置する。そして、接続部２４に加えられていた外力を取り除くことで、接続部２４の弾力によって一対の挿入部２２が互いに離間する。このとき、第一挿入部２２Ａの第一端２２Ａａを第一取付け穴部１４Ａの開口１６ｂに挿入し、第二挿入部２２Ｂの第一端２２Ｂａを第二取付け穴部１４Ｂの開口１６ｃに挿入する。これによって、図４（ｃ）に示すように、一対の挿入部２２が取付け穴部１４に嵌合して固定され、固定部２０が取付け部１０に取り付けられる。 Next, a procedure for attaching the fixing portion 20 to the attaching portion 10 will be described with reference to FIG. As shown in FIG. 4A, when no external force is applied to the connecting portion 24 of the fixing portion 20, the connecting portion 24 maintains a state in which the first distance D1 is larger than the second distance D2. There is. From this state, as shown in FIG. 4B, the pair of insertion portions 22 are aligned with the positions of the openings 16 of the mounting holes 14. Then, as shown by the alternate long and short dash line in FIG. 4B, an external force is applied to the connecting portion 24 to bring the pair of insertion portions 22 close to each other so that the first distance D1 is smaller than the second distance D2. Specifically, the first connecting portion 28A and the second connecting portion 28B of the connecting portion 24 are narrowed so as to be close to each other. As a result, the first end 22Aa of the first insertion portion 22A and the first end 22Ba of the second insertion portion 22B come close to each other. In this state, the pair of insertion portions 22 are arranged between the opening 16b of the first mounting hole portion 14A and the opening 16c of the second mounting hole portion 14B. Then, by removing the external force applied to the connecting portion 24, the pair of inserting portions 22 are separated from each other by the elasticity of the connecting portion 24. At this time, the first end 22Aa of the first insertion portion 22A is inserted into the opening 16b of the first mounting hole portion 14A, and the first end 22Ba of the second insertion portion 22B is inserted into the opening 16c of the second mounting hole portion 14B. .. As a result, as shown in FIG. 4C, the pair of insertion portions 22 are fitted and fixed in the mounting holes 14, and the fixing portions 20 are attached to the mounting portions 10.

本実施の形態によれば、消音部材４０を固定するために用いられる固定構造１は、複数の開口１６が設けられた取付け部１０と、互いに離間して設けられ、複数の開口１６のうちの異なる開口１６ｂ、１６ｃにそれぞれ挿入された一対の挿入部２２と、消音部材４０を保持可能であり、一対の挿入部２２を互いに近接離間可能に接続する接続部２４と、を有する固定部２０と、を備える。 According to the present embodiment, the fixing structure 1 used for fixing the sound deadening member 40 is provided at a distance from the mounting portion 10 provided with the plurality of openings 16, and is among the plurality of openings 16. A fixed portion 20 having a pair of insertion portions 22 inserted into different openings 16b and 16c, and a connection portion 24 capable of holding the sound deadening member 40 and connecting the pair of insertion portions 22 so as to be close to each other. , Equipped with.

上述した構成によれば、一対の挿入部２２を適宜近接離間させて開口１６に挿入することで、固定部２０を取付け部１０に取り付けることができる。このため、前述した従来の固定方法のように固定部をスライドさせるスリット部を設ける必要はないのでその分のスペースが不要であり、また比較的単純な構成の取付け部１０を設けるだけで固定部２０を取り付けられるので、固定部２０の取付け位置の自由度を高めることができる。加えて、従来の固定方法のように消音部材を固定部で押圧する必要はないので、固定部２０の押圧による消音部材４０のへたり等の消音部材４０の損傷も防止できる。さらに、開口１６は挿入部２２を挿入するために使用されるので、開口１６の寸法を挿入部２２が挿入可能な程度まで小さくすることができる。このため、開口１６による笛音などの異音の発生を抑制できる。 According to the above-described configuration, the fixing portion 20 can be attached to the mounting portion 10 by inserting the pair of inserting portions 22 into the opening 16 at appropriate distances from each other. Therefore, unlike the conventional fixing method described above, it is not necessary to provide a slit portion for sliding the fixing portion, so that a space for the slit portion is not required, and the fixing portion is provided only by providing the mounting portion 10 having a relatively simple structure. Since 20 can be attached, the degree of freedom in the attachment position of the fixing portion 20 can be increased. In addition, since it is not necessary to press the muffling member with the fixing portion as in the conventional fixing method, it is possible to prevent damage to the muffling member 40 such as sagging of the muffling member 40 due to the pressing of the fixing portion 20. Further, since the opening 16 is used for inserting the insertion portion 22, the size of the opening 16 can be reduced to such an extent that the insertion portion 22 can be inserted. Therefore, it is possible to suppress the generation of abnormal noise such as whistle due to the opening 16.

また、取付け部１０は、板状部材から形成されている。取付け部１０は、開口が設けられた取付け穴部１４を有している。取付け穴部１４は、板状部材の表面１２に対して突出して形成されている。開口１６は、表面１２に沿った方向に開口している。このように、開口１６は、表面１２に対して突出して形成された取付け穴部１４において表面１２に沿った方向に開口しているため、固定部２０を取付け部１０に取り付ける際に、一対の挿入部２２を表面１２に沿って移動させて開口１６に挿入することができる。したがって、一対の挿入部２２の開口１６への挿入がより容易になる。また、取付け穴部１４は、板状部材をランス曲げすることによって形成されている。これによって、容易に取付け穴部１４を形成することができる。さらに、取付け穴部１４の開口１６の開口面は半円形に形成されており、開口１６に挿入される挿入部２２は開口１６の周縁に囲まれている。よって、開口１６に挿入される挿入部２２はその周方向の広範囲の部分で開口１６に接触している。このため、消音部材４０から固定部２０を介して取付け部１０に加えられる荷重を支持する方向は、従来の固定方法のように消音部材の弾力を受ける方向に限定されず、例えば固定部２０の連結部２８に沿って保持部２６から挿入部２２に向かう方向やその逆に挿入部２２から保持部２６に向かう方向等、様々な方向からの荷重を支持することができる。したがって、固定部２０の取付け位置の自由度をさらに高めることができる。 Further, the mounting portion 10 is formed of a plate-shaped member. The mounting portion 10 has a mounting hole portion 14 provided with an opening. The mounting hole portion 14 is formed so as to project from the surface 12 of the plate-shaped member. The opening 16 opens in the direction along the surface 12. As described above, since the opening 16 is opened in the direction along the surface 12 in the mounting hole portion 14 formed so as to project from the surface 12, a pair of fixing portions 20 are attached to the mounting portion 10 when the fixing portion 20 is attached to the mounting portion 10. The insertion portion 22 can be moved along the surface 12 and inserted into the opening 16. Therefore, it becomes easier to insert the pair of insertion portions 22 into the opening 16. Further, the mounting hole portion 14 is formed by bending a plate-shaped member with a lance. Thereby, the mounting hole portion 14 can be easily formed. Further, the opening surface of the opening 16 of the mounting hole 14 is formed in a semicircular shape, and the insertion portion 22 inserted into the opening 16 is surrounded by the peripheral edge of the opening 16. Therefore, the insertion portion 22 inserted into the opening 16 is in contact with the opening 16 in a wide range in the circumferential direction thereof. Therefore, the direction of supporting the load applied from the sound deadening member 40 to the mounting portion 10 via the fixing portion 20 is not limited to the direction of receiving the elasticity of the sound deadening member as in the conventional fixing method, for example, the fixing portion 20. It is possible to support loads from various directions such as a direction from the holding portion 26 toward the inserting portion 22 along the connecting portion 28 and vice versa, such as a direction from the inserting portion 22 toward the holding portion 26. Therefore, the degree of freedom in the mounting position of the fixing portion 20 can be further increased.

また、固定部２０は、金属製の線材を曲げ成形することによって形成されているので、安価に製作でき、かつ形状の自由度を高めることができる。よって、消音部材４０の配置や形状に応じた形状に、固定部２０を容易に形成することができる。加えて、従来の固定方法で用いられる固定金具では保持部が面状に形成されていたが、固定部２０は線材から形成されているのでこのような面状の部分を有していない。このため、騒音が面状の部分に反射されて発生する反射音を防止できるので、消音部材４０の消音効果をより効率的に得ることができる。 Further, since the fixing portion 20 is formed by bending and molding a metal wire rod, it can be manufactured at low cost and the degree of freedom in shape can be increased. Therefore, the fixing portion 20 can be easily formed into a shape corresponding to the arrangement and shape of the sound deadening member 40. In addition, in the fixing bracket used in the conventional fixing method, the holding portion is formed in a planar shape, but since the fixing portion 20 is formed of a wire rod, it does not have such a planar portion. Therefore, since the reflected sound generated by the noise being reflected by the planar portion can be prevented, the muffling effect of the muffling member 40 can be obtained more efficiently.

また、接続部２４の保持部２６は、一つの平面Ｓに沿って形成されている。このため、平面部を有する消音部材４０を保持部２６によって安定的に保持することができる。 Further, the holding portion 26 of the connecting portion 24 is formed along one plane S. Therefore, the sound deadening member 40 having a flat surface portion can be stably held by the holding portion 26.

なお、本実施の形態では、固定部２０は金属製であるとしたが、これに限らず、樹脂製であってもよい。この場合は、例えば射出成形等で固定部２０を形成することができるので、固定部２０において一対の挿入部２２および連結部２８を線状に形成しつつ、保持部２６を面状に形成することができる。保持部２６を面状に形成すると上述のとおり反射音が増加するが、その一方で保持部２６による消音部材４０の保持の安定性を向上させることができる。また、固定部２０を形成する金属製の線材は円形断面であるとしたが、これに限らず、例えば楕円形断面や多角形断面等であってもよい。 In the present embodiment, the fixing portion 20 is made of metal, but the present invention is not limited to this, and the fixing portion 20 may be made of resin. In this case, since the fixed portion 20 can be formed by, for example, injection molding, the holding portion 26 is formed in a planar shape while the pair of inserting portions 22 and the connecting portion 28 are formed linearly in the fixed portion 20. be able to. When the holding portion 26 is formed in a planar shape, the reflected sound increases as described above, but on the other hand, the stability of holding the sound deadening member 40 by the holding portion 26 can be improved. Further, the metal wire rod forming the fixing portion 20 has a circular cross section, but the present invention is not limited to this, and may be, for example, an elliptical cross section or a polygonal cross section.

また、第一取付け穴部１４Ａと第二取付け穴部１４Ｂとが表面１２上に一列に配置され、第一挿入部２２Ａと第二挿入部２２Ｂとが同軸上に配置されていたが、これに限らない。一対の挿入部２２を取付け穴部１４に固定できる配置であれば、特に限定されない。また、開口１６が設けられた取付け穴部１４は、表面１２に対して突出して形成されていたが、これに限らない。例えば、板状部材から形成された取付け部１０に十分な厚さがある場合には、取付け穴部１４が表面１２から突出する構成を備えずに、表面１２から板状部材の厚さ方向に対して斜めに延びる穴を設けて、この穴を開口１６として用いてもよい。 Further, the first mounting hole portion 14A and the second mounting hole portion 14B were arranged in a row on the surface 12, and the first insertion portion 22A and the second insertion portion 22B were arranged coaxially. Not exclusively. The arrangement is not particularly limited as long as the pair of insertion portions 22 can be fixed to the mounting hole portions 14. Further, the mounting hole portion 14 provided with the opening 16 is formed so as to project from the surface 12, but the present invention is not limited to this. For example, when the mounting portion 10 formed of the plate-shaped member has a sufficient thickness, the mounting hole portion 14 does not have a configuration in which the mounting hole portion 14 protrudes from the surface 12, and the mounting portion 14 is formed in the thickness direction of the plate-shaped member from the surface 12. A hole extending diagonally with respect to the hole may be provided, and this hole may be used as the opening 16.

また、固定部２０の接続部２４の保持部２６は、平面Ｓ上で略Ｕ字状に形成されているとしたが、これに限らない。保持部２６は、消音部材４０をより保持しやすいように、平面Ｓ上で例えば略Ｗ字状に形成されていてもよい。 Further, the holding portion 26 of the connecting portion 24 of the fixing portion 20 is said to be formed in a substantially U shape on the plane S, but the present invention is not limited to this. The holding portion 26 may be formed in a substantially W shape on the plane S so as to more easily hold the sound deadening member 40.

また、一対の挿入部２２を互いに近接離間させる構成として、第一連結部２８Ａおよび第二連結部２８Ｂが互いに近接離間するように弾性変形する構成を利用していたが、これに限らない。例えば、ばね等を利用して一対の挿入部２２を互いに近接離間させるようにしてもよい。 Further, as a configuration in which the pair of insertion portions 22 are separated from each other in close proximity to each other, a configuration in which the first connecting portion 28A and the second connecting portion 28B are elastically deformed so as to be close to each other is used, but the present invention is not limited to this. For example, a spring or the like may be used to separate the pair of insertion portions 22 from each other.

次に、本実施の形態に係る固定部２０の変形例について、図５および図６を参照して説明する。図５は、固定部２０の変形例を示す斜視図である。図６は、固定部２０の他の変形例を示す斜視図である。図５および図６に示すように、固定部２０の保持部２６は、保持する消音部材４０の形状や保持方法等に応じて様々な形状を採用することができる。 Next, a modified example of the fixing portion 20 according to the present embodiment will be described with reference to FIGS. 5 and 6. FIG. 5 is a perspective view showing a modified example of the fixing portion 20. FIG. 6 is a perspective view showing another modified example of the fixing portion 20. As shown in FIGS. 5 and 6, the holding portion 26 of the fixing portion 20 can adopt various shapes depending on the shape of the sound deadening member 40 to be held, the holding method, and the like.

図５に示すように、固定部２０の変形例である固定部２０Ａの保持部２６Ａは、消音部材４０Ａの角部を保持できるように、Ｖ字状に形成された部分を有している。これによって、固定部２０Ａは、消音部材４０Ａをより安定して保持することができる。また、図６に示すように、固定部２０の他の変形例である固定部２０Ｂの保持部２６Ｂは、消音部材４０Ｂの曲面部を保持できるように、円弧状に形成された部分を有している。これによって、固定部２０Ｂは、消音部材４０Ｂをより安定して保持することができる。 As shown in FIG. 5, the holding portion 26A of the fixing portion 20A, which is a modification of the fixing portion 20, has a V-shaped portion so as to hold the corner portion of the sound deadening member 40A. As a result, the fixing portion 20A can hold the sound deadening member 40A more stably. Further, as shown in FIG. 6, the holding portion 26B of the fixing portion 20B, which is another modification of the fixing portion 20, has a portion formed in an arc shape so as to hold the curved surface portion of the sound deadening member 40B. ing. As a result, the fixing portion 20B can hold the sound deadening member 40B more stably.

このほか、例えば消音部材を第一連結部２８Ａと第二連結部２８Ｂとの間に配置し、略Ｕ字状の保持部２６で消音部材の外周を囲むようにして、消音部材を保持してもよい。 In addition, for example, the muffling member may be arranged between the first connecting portion 28A and the second connecting portion 28B, and the muffling member may be held by surrounding the outer periphery of the muffling member with a substantially U-shaped holding portion 26. ..

（実施の形態２）
次に、本発明の実施の形態２に係る固定構造２について、図７を参照して説明する。図７は、固定構造２を示す斜視図である。なお、上述した実施の形態１に係る固定構造１と同様の構成を有する部分については、同一の符号を付し、その詳細な説明を省略する。 (Embodiment 2)
Next, the fixed structure 2 according to the second embodiment of the present invention will be described with reference to FIG. 7. FIG. 7 is a perspective view showing the fixed structure 2. The parts having the same structure as the fixed structure 1 according to the first embodiment described above are designated by the same reference numerals, and detailed description thereof will be omitted.

本実施の形態に係る固定構造２は、一対の挿入部の構成に関して実施の形態１に係る固定構造１と異なっている。固定構造２の固定部１２０は、実施の形態１に係る固定部２０と同様に、一対の挿入部１２２と、接続部２４と、を有している。一対の挿入部１２２を構成する第一挿入部１２２Ａと第二挿入部１２２Ｂとは同軸上に配置されているが、実施の形態１に係る固定部２０とは異なり、第一挿入部１２２Ａの第一端１２２Ａａと第二挿入部１２２Ｂの第一端１２２Ｂａとが対向するように配置されている。また、第一挿入部１２２Ａの第二端１２２Ａｂは第一連結部２８Ａに対して垂直に連結され、第二挿入部１２２Ｂの第二端１２２Ｂｂは第二連結部２８Ｂに対して垂直に連結されている。よって、実施の形態１に係る固定部２０と同様に、第一連結部２８Ａおよび第二連結部２８Ｂが互いに近接離間するように弾性変形することによって、第一挿入部１２２Ａおよび第二挿入部１２２Ｂが互いに近接離間可能である。 The fixed structure 2 according to the present embodiment is different from the fixed structure 1 according to the first embodiment in terms of the configuration of the pair of insertion portions. The fixing portion 120 of the fixing structure 2 has a pair of insertion portions 122 and a connecting portion 24, similarly to the fixing portion 20 according to the first embodiment. The first insertion portion 122A and the second insertion portion 122B constituting the pair of insertion portions 122 are arranged coaxially, but unlike the fixing portion 20 according to the first embodiment, the first insertion portion 122A is the first. One end 122Aa and the first end 122Ba of the second insertion portion 122B are arranged so as to face each other. Further, the second end 122Ab of the first insertion portion 122A is vertically connected to the first connecting portion 28A, and the second end 122Bb of the second insertion portion 122B is vertically connected to the second connecting portion 28B. There is. Therefore, similarly to the fixing portion 20 according to the first embodiment, the first connecting portion 28A and the second connecting portion 28B are elastically deformed so as to be close to each other, so that the first inserting portion 122A and the second inserting portion 122B are separated from each other. Can be separated from each other.

図７に示すように、固定部１２０を取付け部１０に取り付けた状態では、第一取付け穴部１４Ａの開口１６ａに第一挿入部１２２Ａの第一端１２２Ａａが挿入され、第二取付け穴部１４Ｂの開口１６ｄに第二挿入部１２２Ｂの第一端１２２Ｂａが挿入されている。このとき、第一挿入部１２２Ａの第一端１２２Ａａと第二挿入部１２２Ｂの第一端１２２Ｂａとの間の距離である第一距離Ｄ１１は、第一挿入部１２２Ａの第一端１２２Ａａが挿入された第一取付け穴部１４Ａの開口１６ａと第二挿入部１２２Ｂの第一端１２２Ｂａが挿入された第二取付け穴部１４Ｂの開口１６ｄとの間の距離である第二距離Ｄ１２よりも小さい。これにより、固定部１２０は取付け部１０から外れにくくなっている。 As shown in FIG. 7, when the fixing portion 120 is attached to the mounting portion 10, the first end 122Aa of the first insertion portion 122A is inserted into the opening 16a of the first mounting hole portion 14A, and the second mounting hole portion 14B The first end 122Ba of the second insertion portion 122B is inserted into the opening 16d of the above. At this time, the first end 122Aa of the first insertion portion 122A is inserted into the first distance D11, which is the distance between the first end 122Aa of the first insertion portion 122A and the first end 122Ba of the second insertion portion 122B. It is smaller than the second distance D12, which is the distance between the opening 16a of the first mounting hole 14A and the opening 16d of the second mounting hole 14B into which the first end 122Ba of the second insertion hole 122B is inserted. As a result, the fixed portion 120 is less likely to come off from the mounting portion 10.

固定部１２０を取付け部１０に取り付ける場合は、まず、固定部１２０の接続部２４に何も外力が加えられていない状態では、接続部２４は第一距離Ｄ１が第二距離Ｄ２よりも小さい状態を維持している。この状態から、接続部２４に外力を加えて、第一距離Ｄ１が第二距離Ｄ２よりも大きくなるように一対の挿入部１２２を互いに離間させる。具体的には、接続部２４の第一連結部２８Ａおよび第二連結部２８Ｂが互いに離間するように広げられると、第一挿入部１２２Ａの第一端１２２Ａａと第二挿入部１２２Ｂの第一端１２２Ｂａとが互いに離間する。この状態で、一対の挿入部１２２の間に第一取付け穴部１４Ａの開口１６ａと第二取付け穴部１４Ｂの開口１６ｄとを配置する。そして、接続部２４に加えられていた外力を取り除くことで、接続部２４の弾力によって一対の挿入部１２２が互いに近接する。このとき、第一挿入部１２２Ａの第一端１２２Ａａを第一取付け穴部１４Ａの開口１６ａに挿入し、第二挿入部１２２Ｂの第一端１２２Ｂａを第二取付け穴部１４Ｂの開口１６ｄに挿入する。これによって、一対の挿入部１２２が取付け穴部１４に嵌合して固定され、固定部１２０が取付け部１０に取り付けられる。 When attaching the fixing portion 120 to the mounting portion 10, first, in a state where no external force is applied to the connecting portion 24 of the fixing portion 120, the connecting portion 24 has a first distance D1 smaller than a second distance D2. Is maintained. From this state, an external force is applied to the connecting portion 24 to separate the pair of insertion portions 122 from each other so that the first distance D1 is larger than the second distance D2. Specifically, when the first connecting portion 28A and the second connecting portion 28B of the connecting portion 24 are expanded so as to be separated from each other, the first end 122Aa of the first insertion portion 122A and the first end of the second insertion portion 122B are expanded. 122Ba and 122Ba are separated from each other. In this state, the opening 16a of the first mounting hole 14A and the opening 16d of the second mounting hole 14B are arranged between the pair of insertion portions 122. Then, by removing the external force applied to the connecting portion 24, the pair of inserting portions 122 come close to each other due to the elasticity of the connecting portion 24. At this time, the first end 122Aa of the first insertion portion 122A is inserted into the opening 16a of the first mounting hole portion 14A, and the first end 122Ba of the second insertion portion 122B is inserted into the opening 16d of the second mounting hole portion 14B. .. As a result, the pair of insertion portions 122 are fitted and fixed in the mounting holes 14, and the fixing portions 120 are attached to the mounting portions 10.

このように構成された固定構造２においても、実施の形態１に係る固定構造１と同様の効果を得ることができる。 Even in the fixed structure 2 configured in this way, the same effect as that of the fixed structure 1 according to the first embodiment can be obtained.

次に、本実施の形態に係る固定構造２の変形例について、図８を参照して説明する。図８は、固定構造２の変形例を示す斜視図である。図８に示すように、固定構造２の変形例である固定構造２Ａの取付け部１１０は、取付け穴部１１４を有している。取付け穴部１１４には、開口１６ｅおよび開口１６ｆの二つの開口１６が設けられている。取付け穴部１１４、開口１６ｅおよび開口１６ｆはそれぞれ、第一取付け穴部１４Ａ、開口１６ａおよび開口１６ｂと同様に構成されている。また、取付け穴部１１４の軸方向の外形寸法は、第一挿入部１２２Ａの軸方向の外形寸法と第二挿入部１２２Ｂの軸方向の外形寸法との和よりも大きく設定されている。 Next, a modified example of the fixed structure 2 according to the present embodiment will be described with reference to FIG. FIG. 8 is a perspective view showing a modified example of the fixed structure 2. As shown in FIG. 8, the mounting portion 110 of the fixed structure 2A, which is a modification of the fixed structure 2, has a mounting hole portion 114. The mounting hole 114 is provided with two openings 16 of an opening 16e and an opening 16f. The mounting hole 114, the opening 16e, and the opening 16f are configured in the same manner as the first mounting hole 14A, the opening 16a, and the opening 16b, respectively. Further, the axial outer dimension of the mounting hole 114 is set to be larger than the sum of the axial outer dimension of the first insertion portion 122A and the axial outer dimension of the second insertion portion 122B.

固定部１２０を取付け部１１０に取り付けた状態では、取付け穴部１１４の開口１６ｅに第一挿入部１２２Ａの第一端１２２Ａａが挿入され、取付け穴部１１４の開口１６ｆに第二挿入部１２２Ｂの第一端１２２Ｂａが挿入されている。このとき、第一挿入部１２２Ａの第一端１２２Ａａと第二挿入部１２２Ｂの第一端１２２Ｂａとの間の距離である第一距離Ｄ１１は、第一挿入部１２２Ａの第一端１２２Ａａが挿入された取付け穴部１１４の開口１６ｅと第二挿入部１２２Ｂの第一端１２２Ｂａが挿入された取付け穴部１１４の開口１６ｆとの間の距離である第二距離Ｄ１２Ａよりも小さい。 In the state where the fixing portion 120 is attached to the mounting portion 110, the first end 122Aa of the first insertion portion 122A is inserted into the opening 16e of the mounting hole portion 114, and the second insertion portion 122B is inserted into the opening 16f of the mounting hole portion 114. 122Ba is inserted at one end. At this time, the first end 122Aa of the first insertion portion 122A is inserted into the first distance D11, which is the distance between the first end 122Aa of the first insertion portion 122A and the first end 122Ba of the second insertion portion 122B. It is smaller than the second distance D12A, which is the distance between the opening 16e of the mounting hole 114 and the opening 16f of the mounting hole 114 into which the first end 122Ba of the second insertion portion 122B is inserted.

この固定構造２Ａのように、取付け部１１０に取付け穴部１１４が一つだけ設けられた構成であっても、上述した固定構造２と同様の効果を得ることができる。 Even if the mounting portion 110 is provided with only one mounting hole 114 as in the fixed structure 2A, the same effect as that of the fixed structure 2 described above can be obtained.

（実施の形態３）
次に、本発明の実施の形態３に係る固定構造３について、図９を参照して説明する。図９は、固定構造３を示す斜視図である。なお、上述した実施の形態１に係る固定構造１と同様の構成を有する部分については、同一の符号を付し、その詳細な説明を省略する。 (Embodiment 3)
Next, the fixed structure 3 according to the third embodiment of the present invention will be described with reference to FIG. FIG. 9 is a perspective view showing the fixed structure 3. The parts having the same structure as the fixed structure 1 according to the first embodiment described above are designated by the same reference numerals, and detailed description thereof will be omitted.

本実施の形態に係る固定構造３は、取付け部の構成に関して実施の形態１に係る固定構造１と異なっている。図９に示すように、固定構造３は、取付け部２１０と、固定部２２０と、を備える。取付け部２１０は、複数の開口１６として開口１６ｇおよび開口１６ｈが設けられている。本実施の形態では、取付け部２１０は、開口１６ｇおよび開口１６ｈが設けられた取付け穴部２１４を有している。取付け穴部２１４は、取付け部２１０の表面１２に対して窪んで形成されている。また、取付け穴部２１４は半円筒形状の外形を有しており、開口１６ｇおよび開口１６ｈはその半円筒形状の軸方向の両端に設けられている。取付け穴部２１４は、開口１６ｇから開口１６ｈまで軸方向に貫通されており、開口１６ｇと開口１６ｈとの間に窪み部２１４ａが形成されている。開口１６ｇの開口面および開口１６ｈの開口面はともに、表面１２に対して垂直であり、半円形状を有している。 The fixed structure 3 according to the present embodiment is different from the fixed structure 1 according to the first embodiment in terms of the configuration of the mounting portion. As shown in FIG. 9, the fixing structure 3 includes a mounting portion 210 and a fixing portion 220. The mounting portion 210 is provided with an opening 16g and an opening 16h as a plurality of openings 16. In the present embodiment, the mounting portion 210 has a mounting hole portion 214 provided with an opening 16g and an opening 16h. The mounting hole portion 214 is formed so as to be recessed with respect to the surface 12 of the mounting portion 210. Further, the mounting hole portion 214 has a semi-cylindrical outer shape, and openings 16 g and openings 16 h are provided at both ends of the semi-cylindrical shape in the axial direction. The mounting hole portion 214 is axially penetrated from the opening 16g to the opening 16h, and a recess portion 214a is formed between the opening 16g and the opening 16h. Both the opening surface of the opening 16g and the opening surface of the opening 16h are perpendicular to the surface 12 and have a semicircular shape.

固定部２２０は、一対の挿入部２２と、接続部２２４と、を有している。接続部２２４は、保持部２６に加えて、連結部２２８をさらに有している。連結部２２８は、第一挿入部２２Ａの第二端２２Ａｂと保持部２６の第一端２６ａとを連結する第一連結部２２８Ａと、第二挿入部２２Ｂの第二端２２Ｂｂと保持部２６の第二端２６ｂとを連結する第二連結部２２８Ｂと、を有している。第一連結部２２８Ａは、第一部分２２８Ａａと第二部分２２８Ａｂとから構成されるＬ字状に形成されている。第一部分２２８Ａａは、取付け穴部２１４の窪み部２１４ａに入り込む部分であり、第一挿入部２２Ａの第二端２２Ａｂと連結されている。第二部分２２８Ａｂは、取付け部２１０の表面１２に沿って配置される部分であり、保持部２６の第一端２６ａと連結されている。同様に、第二連結部２２８Ｂは、第一部分２２８Ｂａと第二部分２２８Ｂｂとから構成されるＬ字状に形成されている。第一部分２２８Ｂａは、取付け穴部２１４の窪み部２１４ａに入り込む部分であり、第二挿入部２２Ｂの第二端２２Ｂｂと連結されている。第二部分２２８Ｂｂは、取付け部２１０の表面１２に沿って配置される部分であり、保持部２６の第二端２６ｂと連結されている。第一連結部２２８Ａおよび第二連結部２２８Ｂが互いに近接離間するように弾性変形することによって、第一挿入部２２Ａおよび第二挿入部２２Ｂが互いに近接離間可能である。 The fixing portion 220 has a pair of inserting portions 22 and a connecting portion 224. The connecting portion 224 further includes a connecting portion 228 in addition to the holding portion 26. The connecting portion 228 is a first connecting portion 228A that connects the second end 22Ab of the first insertion portion 22A and the first end 26a of the holding portion 26, and the second end 22Bb and the holding portion 26 of the second inserting portion 22B. It has a second connecting portion 228B that connects the second end 26b. The first connecting portion 228A is formed in an L shape composed of a first portion 228Aa and a second portion 228Ab. The first portion 228Aa is a portion that enters the recessed portion 214a of the mounting hole portion 214, and is connected to the second end 22Ab of the first insertion portion 22A. The second portion 228Ab is a portion arranged along the surface 12 of the mounting portion 210 and is connected to the first end 26a of the holding portion 26. Similarly, the second connecting portion 228B is formed in an L shape composed of a first portion 228Ba and a second portion 228Bb. The first portion 228Ba is a portion that enters the recessed portion 214a of the mounting hole portion 214, and is connected to the second end 22Bb of the second insertion portion 22B. The second portion 228Bb is a portion arranged along the surface 12 of the mounting portion 210 and is connected to the second end 26b of the holding portion 26. By elastically deforming the first connecting portion 228A and the second connecting portion 228B so as to be close to each other, the first insertion portion 22A and the second insertion portion 22B can be closely separated from each other.

固定部２２０を取付け部２１０に取り付けた状態では、取付け穴部２１４の開口１６ｇに第一挿入部２２Ａの第一端２２Ａａが挿入され、取付け穴部２１４の開口１６ｈに第二挿入部２２Ｂの第一端２２Ｂａが挿入されている。このとき、第一挿入部２２Ａの第一端２２Ａａと第二挿入部２２Ｂの第一端２２Ｂａとの間の距離である第一距離Ｄ２１は、第一挿入部２２Ａの第一端２２Ａａが挿入された取付け穴部２１４の開口１６ｇと第二挿入部２２Ｂの第一端２２Ｂａが挿入された取付け穴部２１４の開口１６ｈとの間の距離である第二距離Ｄ２２よりも大きい。これにより、固定部２２０は取付け部２１０から外れにくくなっている。 In the state where the fixing portion 220 is attached to the mounting portion 210, the first end 22Aa of the first insertion portion 22A is inserted into the opening 16g of the mounting hole portion 214, and the second insertion portion 22B is inserted into the opening 16h of the mounting hole portion 214. 22Ba is inserted at one end. At this time, the first end 22Aa of the first insertion portion 22A is inserted into the first distance D21, which is the distance between the first end 22Aa of the first insertion portion 22A and the first end 22Ba of the second insertion portion 22B. It is larger than the second distance D22, which is the distance between the opening 16g of the mounting hole 214 and the opening 16h of the mounting hole 214 into which the first end 22Ba of the second insertion 22B is inserted. As a result, the fixed portion 220 is less likely to come off from the mounting portion 210.

固定部２２０を取付け部２１０に取り付ける場合は、まず、固定部２２０の接続部２２４に何も外力が加えられていない状態では、接続部２２４は第一距離Ｄ２１が第二距離Ｄ２２よりも大きい状態を維持している。この状態から、接続部２２４に外力を加えて、第一距離Ｄ２１が第二距離Ｄ２２よりも小さくなるように一対の挿入部２２を互いに近接させる。具体的には、接続部２２４の第一連結部２２８Ａおよび第二連結部２２８Ｂが互いに近接するように押し狭めると、第一挿入部２２Ａの第一端２２Ａａと第二挿入部２２Ｂの第一端２２Ｂａとが互いに近接する。この状態で、取付け穴部２１４の開口１６ｇと開口１６ｈとの間の窪み部２１４ａに一対の挿入部２２を配置する。そして、接続部２２４に加えられていた外力を取り除くことで、接続部２２４の弾力によって一対の挿入部２２が互いに離間する。このとき、第一挿入部２２Ａの第一端２２Ａａを取付け穴部２１４の開口１６ｇに挿入し、第二挿入部２２Ｂの第一端２２Ｂａを取付け穴部２１４の開口１６ｈに挿入する。これによって、一対の挿入部２２が取付け穴部２１４に嵌合して固定され、固定部２２０が取付け部２１０に取り付けられる。 When attaching the fixing portion 220 to the mounting portion 210, first, in a state where no external force is applied to the connecting portion 224 of the fixing portion 220, the connecting portion 224 has a state in which the first distance D21 is larger than the second distance D22. Is maintained. From this state, an external force is applied to the connecting portion 224 to bring the pair of insertion portions 22 close to each other so that the first distance D21 is smaller than the second distance D22. Specifically, when the first connecting portion 228A and the second connecting portion 228B of the connecting portion 224 are narrowed so as to be close to each other, the first end 22Aa of the first insertion portion 22A and the first end of the second insertion portion 22B are narrowed. 22Ba and 22Ba are close to each other. In this state, the pair of insertion portions 22 are arranged in the recessed portion 214a between the opening 16g and the opening 16h of the mounting hole portion 214. Then, by removing the external force applied to the connecting portion 224, the pair of inserting portions 22 are separated from each other by the elasticity of the connecting portion 224. At this time, the first end 22Aa of the first insertion portion 22A is inserted into the opening 16g of the mounting hole portion 214, and the first end 22Ba of the second insertion portion 22B is inserted into the opening 16h of the mounting hole portion 214. As a result, the pair of insertion portions 22 are fitted and fixed in the mounting holes 214, and the fixing portions 220 are attached to the mounting portions 210.

このように構成された固定構造３においても、実施の形態１に係る固定構造１と同様の効果を得ることができる。また、取付け穴部２１４は、表面１２に対して窪んで形成されているので、取付け穴部２１４の上に消音部材４０を配置した場合の表面１２と消音部材４０との隙間を小さくすることができ、開口１６による笛音などの異音の発生をより確実に抑制できる。 Even in the fixed structure 3 configured in this way, the same effect as that of the fixed structure 1 according to the first embodiment can be obtained. Further, since the mounting hole portion 214 is formed to be recessed with respect to the surface 12, the gap between the surface 12 and the sound deadening member 40 when the sound deadening member 40 is arranged on the mounting hole portion 214 can be reduced. It is possible to more reliably suppress the generation of abnormal noise such as whistle sound due to the opening 16.

取付け部３１０は、筐体６０に設けられている。本実施の形態では、取付け部３１０Ａおよび取付け部３１０Ｂの二つの取付け部３１０が筐体６０に設けられている。取付け部３１０Ａは、筐体６０において開口部６２と側部６６Ｃとの間の側部６６Ａに設けられ、取付け部３１０Ｂは、筐体６０の側部６６Ａに対向する側部６６Ｂに設けられている。取付け部３１０Ａおよび取付け部３１０Ｂはそれぞれ、実施の形態１に係る固定構造１の取付け部１０と同様に構成されており、取付け穴部１４を有する。取付け部３１０Ａの取付け穴部１４は、側部６６Ａの内面（表面）６６Ａｓに対して突出して形成されている。取付け部３１０Ｂの取付け穴部１４は、側部６６Ｂの内面（表面）６６Ｂｓに対して突出して形成されている。また、取付け部３１０Ａおよび取付け部３１０Ｂはそれぞれ、筐体６０内において消音部材１４０の開口部６２に向かう面１４０ｓよりも開口部６２に近い位置に配置されている。 The mounting portion 310 is provided in the housing 60. In the present embodiment, the housing 60 is provided with two mounting portions 310, a mounting portion 310A and a mounting portion 310B. The mounting portion 310A is provided on the side portion 66A between the opening 62 and the side portion 66C in the housing 60, and the mounting portion 310B is provided on the side portion 66B facing the side portion 66A of the housing 60. .. Each of the mounting portion 310A and the mounting portion 310B is configured in the same manner as the mounting portion 10 of the fixed structure 1 according to the first embodiment, and has a mounting hole portion 14. The mounting hole portion 14 of the mounting portion 310A is formed so as to project from the inner surface (surface) 66As of the side portion 66A. The mounting hole portion 14 of the mounting portion 310B is formed so as to project from the inner surface (surface) 66Bs of the side portion 66B. Further, the mounting portion 310A and the mounting portion 310B are respectively arranged in the housing 60 at positions closer to the opening 62 than the surface 140s of the sound deadening member 140 toward the opening 62.

固定部２０は、取付け部３１０Ａおよび取付け部３１０Ｂに対応して、二つ設けられている。すなわち、本実施の形態では、取付け部３１０および固定部２０は、二組設けられている。 Two fixing portions 20 are provided corresponding to the mounting portion 310A and the mounting portion 310B. That is, in the present embodiment, two sets of the mounting portion 310 and the fixing portion 20 are provided.

消音部材１４０を筐体６０内に取り付ける際には、消音部材１４０を筐体６０内の設置面６４に合わせて配置する。固定部２０の保持部２６を消音部材１４０に向けた状態で、上述した実施の形態１と同様にして、固定部２０を取付け部３１０Ａと取付け部３１０Ｂとの各々に取り付ける。これによって、二つの固定部２０の保持部２６が消音部材１４０の面１４０ｓにそれぞれ当接し、消音部材１４０が設置面６４と固定部２０との間に保持される。 When the sound deadening member 140 is mounted in the housing 60, the sound deadening member 140 is arranged so as to be aligned with the installation surface 64 in the housing 60. With the holding portion 26 of the fixing portion 20 facing the sound deadening member 140, the fixing portion 20 is attached to each of the mounting portion 310A and the mounting portion 310B in the same manner as in the first embodiment described above.

本実施の形態に係る消音装置５０においても、実施の形態１に係る固定構造１と同様の効果を得ることができる。加えて、固定部２０の取付け位置の自由度が高くできることから、要求される消音性能に応じて設定される様々な配置や形状の消音部材１４０にも対応することができるので、より効果的に消音することができる。また、取付け部３１０および固定部２０を二組設けることによって、より確実に消音部材１４０を保持することができる。 The sound deadening device 50 according to the present embodiment can also obtain the same effect as the fixed structure 1 according to the first embodiment. In addition, since the degree of freedom in the mounting position of the fixing portion 20 can be increased, it is possible to correspond to the muffling member 140 having various arrangements and shapes set according to the required muffling performance, which is more effective. Can be muted. Further, by providing two sets of the mounting portion 310 and the fixing portion 20, the sound deadening member 140 can be held more reliably.

なお、本実施の形態では、取付け部３１０および固定部２０は二組設けられているとしたが、これに限らない。取付け部３１０および固定部２０の組数は、一組でもよいし三組以上の複数組でもよく、固定部２０で保持する消音部材１４０の配置や形状、大きさ等に応じて、適宜設定することができる。 In the present embodiment, it is assumed that two sets of the mounting portion 310 and the fixing portion 20 are provided, but the present invention is not limited to this. The number of sets of the mounting portion 310 and the fixing portion 20 may be one set or a plurality of sets of three or more sets, and are appropriately set according to the arrangement, shape, size, etc. of the sound deadening member 140 held by the fixing portion 20. be able to.

また、消音部材１４０を設置面６４と固定部２０との間に保持していたが、これに限らず、複数の固定部２０の保持部２６の間に消音部材１４０を保持してもよい。例えば、消音部材１４０を筐体６０の側部６６Ｃから離間して配置する場合には、側部６６Ｃと消音部材１４０との間に取付け部３１０および固定部２０をさらに設けて、この固定部２０の保持部２６と、消音部材１４０の面１４０ｓと開口部６２との間に設けられた固定部２０の保持部２６との間に消音部材１４０を保持することができる。なお、この場合には、例えば側部６６Ａの内面６６Ａｓを設置面として消音部材１４０が配置される。 Further, the muffling member 140 is held between the installation surface 64 and the fixing portion 20, but the present invention is not limited to this, and the muffling member 140 may be held between the holding portions 26 of the plurality of fixing portions 20. For example, when the sound deadening member 140 is arranged apart from the side portion 66C of the housing 60, a mounting portion 310 and a fixing portion 20 are further provided between the side portion 66C and the sound deadening member 140, and the fixing portion 20 is provided. The muffling member 140 can be held between the holding portion 26 of the above and the holding portion 26 of the fixing portion 20 provided between the surface 140s of the muffling member 140 and the opening 62. In this case, for example, the sound deadening member 140 is arranged with the inner surface 66As of the side portion 66A as the installation surface.

また、開口部６２は、直方体形状の筐体６０において開放された一面に形成されていたが、これに限らない。開口部６２は、消音部材１４０で消音すべき音が筐体６０内に伝播するように開口していればよい。また、消音部材１４０で消音すべき音が筐体６０内で発生する場合には、開口部６２は設けられなくてもよい。 Further, the opening 62 is formed on one open surface in the rectangular parallelepiped housing 60, but the present invention is not limited to this. The opening 62 may be opened so that the sound to be muted by the muffling member 140 propagates into the housing 60. Further, when the sound to be muted by the muffling member 140 is generated in the housing 60, the opening 62 may not be provided.

次に、本実施の形態に係る消音装置５０の変形例について、図１１を参照して説明する。図１１は、消音装置５０の変形例を示す斜視図である。図１１に示すように、消音装置５０の変形例である消音装置５０Ａは、取付け部３１０の配置および固定部２０の向きが消音装置５０と異なっている。消音装置５０Ａでは、取付け部３１０は、筐体内６０において設置面６４と消音部材１４０の面１４０ｓとの間に配置されている。固定部２０は、消音装置５０の構成とは逆に、保持部２６において連結部２８が延びる側を消音部材１４０の面１４０ｓに向けた状態で、取付け部３１０に取り付けられている。これによって、取付け部３１０と固定部２０の保持部２６以外の部分とは、消音部材１４０によって覆われる。 Next, a modified example of the muffling device 50 according to the present embodiment will be described with reference to FIG. FIG. 11 is a perspective view showing a modified example of the muffling device 50. As shown in FIG. 11, in the muffling device 50A, which is a modification of the muffling device 50, the arrangement of the mounting portion 310 and the orientation of the fixing portion 20 are different from those of the muffling device 50. In the sound deadening device 50A, the mounting portion 310 is arranged between the installation surface 64 and the surface 140s of the sound deadening member 140 in the housing 60. Contrary to the configuration of the muffling device 50, the fixing portion 20 is attached to the mounting portion 310 with the side of the holding portion 26 extending from the connecting portion 28 facing the surface 140s of the muffling member 140. As a result, the mounting portion 310 and the portion of the fixing portion 20 other than the holding portion 26 are covered with the sound deadening member 140.

このような構成の消音装置５０Ａであっても、上述した消音装置５０と同様の効果を得ることができる。さらに、取付け部３１０の取付け穴部１４は消音部材１４０に覆われているので、取付け部３１０の取付け穴部１４に設けられた開口１６による異音の発生をより確実に抑制することができる。 Even with the muffling device 50A having such a configuration, the same effect as that of the muffling device 50 described above can be obtained. Further, since the mounting hole portion 14 of the mounting portion 310 is covered with the sound deadening member 140, it is possible to more reliably suppress the generation of abnormal noise due to the opening 16 provided in the mounting hole portion 14 of the mounting portion 310.
