Therefore, the diameter of the ring body 12c can be reduced by sandwiching the snap ring 12 so that both end portions 12a and 12b are brought close to each other. By reducing the diameter, the snap ring 12 can be inserted into the inner peripheral surface 22b of the second support portion 22. Further, on the inner peripheral surface 22b of the second support portion 22, a mounting groove 22c extending over the entire circumference in the circumferential direction is formed in the vicinity of the opening on the other end side. By fitting the outer edge portion of the ring body 12c elastically restored into the mounting groove 22c, the snap ring 12 is internally fitted into the second support portion 22.

Therefore, the flange 3d engages with the recess 12d, and the temperature sensor 3 is restricted from moving from one end to the other in the axial direction. Further, the flange 3d is adapted to enter the mounting groove 22c.
  • the flange 3d does not necessarily have to be formed on the entire circumference. That is, the flange 3d may be formed at least in a part in the circumferential direction.

Further, since the temperature sensor 3 is supported at two points, the distance from the other end of the temperature sensor 3 to the support point (that is, from the other end to the second supported portion 3c) is as compared with the case where the temperature sensor 3 is supported at one point. Distance) can be shortened. Therefore, the natural frequency of the temperature sensor 3 can be shifted to the high frequency side. As a result, it is possible to prevent the temperature sensor 3 from resonating when the temperature sensor 3 vibrates in a low frequency region during use.

Further, in the support structure 1, the snap ring 12 can be elastically deformed so as to reduce the diameter and inserted into the second support portion 22, so that the temperature sensor 3 can be easily supported. Further, by using the snap ring 12, it is possible to easily realize the two-point support of the temperature sensor 3.

That is, the opening 12f of the snap ring 12B is smaller than the diameter of the mounting groove 22e. Therefore, when the snap ring 12 is inserted into the mounting groove 22e through the opening 12f, the diameter of the snap ring 12 itself expands.

　タンク内の温度をより正確に測定するためには、タンク内の中心部分の温度を測定することが好ましく、例えばより長い温度センサが採用されることが好ましい。しかし、温度センサを長くすると、タンク等に搭載した際に生じる振動によって振れるので、温度センサが安定的に支持されることが好ましい。なお、温度センサ以外の棒状部材も同様の課題が生じる。また、棒状部材を支持する際には、棒状部材を簡単に支持できることが望ましい。 In order to measure the temperature inside the tank more accurately, it is preferable to measure the temperature of the central portion inside the tank, for example, it is preferable to adopt a longer temperature sensor. However, if the temperature sensor is lengthened, it will fluctuate due to vibration generated when it is mounted on a tank or the like, so it is preferable that the temperature sensor is stably supported. The same problem arises with rod-shaped members other than the temperature sensor. Further, when supporting the rod-shaped member, it is desirable that the rod-shaped member can be easily supported.
　そこで本発明は、棒状部材を長くしても安定的に支持することができる棒状部材の支持構造、及びタンクバルブを提供することを第１の目的としている。 Therefore, the first object of the present invention is to provide a support structure for a rod-shaped member that can be stably supported even if the rod-shaped member is lengthened, and a tank valve.
　また、本発明は、棒状部材を簡単に支持することができる棒状部材の支持構造、及びスナップリングを提供することを第２の目的としている。 A second object of the present invention is to provide a support structure for a rod-shaped member capable of easily supporting the rod-shaped member, and a snap ring.
　第１の発明である棒状部材の支持構造は、第１被支持部と、前記第１被支持部と異なる第２被支持部とを有する棒状部材の支持構造であって、前記第１被支持部を支持する第１支持部と、前記第２被支持部に沿わせて配置される第２支持部と、弾性変形させて前記第２支持部に取り付けられて前記第２被支持部を前記第２支持部に押し付けるリング状の支持補助部材とを備えるものである。 The support structure for a rod-shaped member according to the first invention is a support structure for a rod-shaped member having a first supported portion and a second supported portion different from the first supported portion, and the first supported portion. The first supported portion that supports the portion, the second supported portion that is arranged along the second supported portion, and the second supported portion that is elastically deformed and attached to the second supported portion are described. It is provided with a ring-shaped support auxiliary member that is pressed against the second support portion.
　第１の発明に従えば、棒状部材を２点で支持することによって、棒状部材を長くしてもそれを安定して支持することができる。また、支持補助部材を用いることによって、棒状部材を簡易な構造で２点支持することができる。 According to the first invention, by supporting the rod-shaped member at two points, the rod-shaped member can be stably supported even if the rod-shaped member is lengthened. Further, by using the support auxiliary member, the rod-shaped member can be supported at two points with a simple structure.
　第２の発明のタンクバルブは、タンク容器の口部に取り付けられ、第１支持部と前記第１支持部より前記タンク容器の内側に位置する第２支持部とを有するタンクバルブであって、前記第１支持部に支持される第１被支持部と、前記第２支持部に沿わせて配置される第２被支持部とを有する棒状部材と、前記第２被支持部を前記第２支持部に支持させる支持補助部材と、を備え、前記棒状部材は、前記第２支持部から突き出る先端を前記第２支持部より前記タンク容器の内側に位置させ、前記第２被支持部から前記棒状部材の先端までの長さが前記第１被支持部から前記第２被支持部までの長さより大きくなるように配置されているものである。 The tank valve of the second invention is a tank valve attached to the mouth of the tank container and having a first support portion and a second support portion located inside the tank container from the first support portion. A rod-shaped member having a first supported portion supported by the first supported portion, a second supported portion arranged along the second supported portion, and the second supported portion being the second supported portion. A support auxiliary member for supporting the support portion is provided, and the rod-shaped member has a tip protruding from the second support portion located inside the tank container from the second support portion, and the rod-shaped member is said to be from the second supported portion to the inside of the tank container. It is arranged so that the length to the tip of the rod-shaped member is larger than the length from the first supported portion to the second supported portion.
　第２の発明によれば、棒状部材の先端をタンク容器内においてより内側に配置しつつ、棒状部材を安定的に支持することができる。即ち、棒状部材を長くしつつ安定的に支持することができる。 According to the second invention, the rod-shaped member can be stably supported while the tip of the rod-shaped member is arranged inside the tank container. That is, the rod-shaped member can be stably supported while being lengthened.
　第３の発明のスナップリングは、基体に内嵌め又は外嵌めされるリング本体と、前記基体に沿わして配置される棒状部材を入れることができる凹部とを有し、前記凹部は、前記リング本体が前記基体に嵌め込まれた状態で前記棒状部材を前記基体に押し付けることができる。 The snap ring of the third invention has a ring body that is internally or externally fitted to the substrate, and a recess into which a rod-shaped member arranged along the substrate can be inserted, and the recess is the ring. The rod-shaped member can be pressed against the substrate with the main body fitted to the substrate.
　第３の発明によれば、凹部に棒状部材を入れて基体に嵌め込むことによって棒状部材を支持することができるので、簡単な構造の支持構造を構成することができる。 According to the third invention, since the rod-shaped member can be supported by inserting the rod-shaped member into the recess and fitting it into the substrate, a support structure having a simple structure can be constructed.
　第１の発明の棒状部材の支持構造及び第２の発明のタンクバルブによれば、棒状部材を長くしても安定的に支持することができる。 According to the support structure of the rod-shaped member of the first invention and the tank valve of the second invention, the rod-shaped member can be stably supported even if it is lengthened.
　また、第１の発明の棒状部材の支持構造及び第３の発明のスナップリングによれば、棒状部材を簡単に支持することができる。 Further, according to the support structure of the rod-shaped member of the first invention and the snap ring of the third invention, the rod-shaped member can be easily supported.

The concept of the direction used in the following description is used for convenience in the explanation, and does not limit the direction of the configuration of the invention to that direction. Further, the support structures 1, 1A to 1C and the tank valves 2, 2B described below are only one embodiment and one embodiment of the present invention. Therefore, the present invention is not limited to the following embodiments and examples, and can be added, deleted, or changed without departing from the spirit of the invention.
　［第１実施形態］
　図１に示す支持構造１は、例えばタンクバルブに備わっており、棒状部材を支持している。本実施形態において棒状部材は、例えば温度センサ３である。ただし、棒状部材は、温度センサ３の他、噴射管や配管等であってもよく、長尺の部材であればよい。ここで長尺とは、棒状部材の幅又は外径に対してその長さが１０倍以上であることを示す。そして、本実施形態において、支持構造１は、以下のように構成されている。即ち、支持構造１は、基体１１と、スナップリング１２とを備えている。基体１１は、温度センサ３を２点で支持する。基体１１は、第１支持部２１と第２支持部２２とを有している。第１支持部２１は、大略円柱状に形成されている。第１支持部２１の一端面には挿通孔２１ａが形成されている。挿通孔２１ａは、基体１１の軸線方向に沿って延在しており、そこには温度センサ３の一端側部分、即ち第１被支持部３ａが挿入されて支持されている。即ち、温度センサ３は、他端、即ち先端３ｅが自由端となる片持ち梁のように基体１１に支持されている。なお、温度センサ３の第１被支持部３ａは、必ずしも第１支持部２１に直接支持されている必要はなく、第１支持部２１に固定される別部材を介して第１支持部２１に間接的に支持されていてもよい。また、温度センサ３の残余部分３ｂは、挿通孔２１ａから突き出ており、それを支持すべく第２支持部２２が第１支持部２１に設けられている。 [First Embodiment]
The support structure 1 shown in FIG. 1 is provided in, for example, a tank valve and supports a rod-shaped member. In this embodiment, the rod-shaped member is, for example, a temperature sensor 3. However, the rod-shaped member may be an injection pipe, a pipe, or the like in addition to the temperature sensor 3, and may be a long member. Here, the term "long" means that the length of the rod-shaped member is 10 times or more the width or outer diameter of the rod-shaped member. Then, in the present embodiment, the support structure 1 is configured as follows. That is, the support structure 1 includes a substrate 11 and a snap ring 12. The substrate 11 supports the temperature sensor 3 at two points. The substrate 11 has a first support portion 21 and a second support portion 22. The first support portion 21 is formed in a substantially columnar shape. An insertion hole 21a is formed on one end surface of the first support portion 21. The insertion hole 21a extends along the axial direction of the substrate 11, and one end side portion of the temperature sensor 3, that is, the first supported portion 3a is inserted and supported therein. That is, the temperature sensor 3 is supported by the substrate 11 like a cantilever whose other end, that is, the tip 3e is a free end. The first supported portion 3a of the temperature sensor 3 does not necessarily have to be directly supported by the first supported portion 21, and is attached to the first supported portion 21 via another member fixed to the first supported portion 21. It may be indirectly supported. Further, the remaining portion 3b of the temperature sensor 3 protrudes from the insertion hole 21a, and a second support portion 22 is provided in the first support portion 21 to support the remaining portion 3b.
　第２支持部２２は、大略円筒状に形成されている。第２支持部２２は、一端側の開口部（図１の上側の開口部）に第１支持部２１を嵌め込んでいる。これにより、第２支持部２２は、第１支持部２１の一端部分に被せるように固定されている。このように配置される第１支持部２１において、挿通孔２１ａは、平面視で第２支持部２２の内周面２２ｂに内接するように配置されている。それ故、温度センサ３において挿通孔２１ａから突き出る部分、即ち温度センサ３の第１被支持部３ａを除いた残余部分３ｂが、第２支持部２２の内周面２２ｂに沿って配置されている。その状態で、残余部分３ｂは内孔２２ａを延在している。また、残余部分３ｂは、第２支持部２２から外方へと突き出ている。第２支持部２２には、残余部分３ｂを支持すべくスナップリング１２が取り付けられている。 The second support portion 22 is formed in a substantially cylindrical shape. The second support portion 22 fits the first support portion 21 into the opening on one end side (the upper opening in FIG. 1). As a result, the second support portion 22 is fixed so as to cover one end portion of the first support portion 21. In the first support portion 21 arranged in this way, the insertion hole 21a is arranged so as to be inscribed in the inner peripheral surface 22b of the second support portion 22 in a plan view. Therefore, the portion of the temperature sensor 3 protruding from the insertion hole 21a, that is, the remaining portion 3b excluding the first supported portion 3a of the temperature sensor 3 is arranged along the inner peripheral surface 22b of the second support portion 22. .. In that state, the residual portion 3b extends the inner hole 22a. Further, the remaining portion 3b protrudes outward from the second support portion 22. A snap ring 12 is attached to the second support portion 22 to support the remaining portion 3b.
　支持補助部材の一例であるスナップリング１２は、内嵌め型のスナップリングである。図２に示すように、スナップリング１２は、平面視でリング状（より詳しくは大略Ｃ形）のワッシャーで弾性変形可能に形成されている。それ故、スナップリング１２は、その両端部１２ａ，１２ｂを近づけるように挟むことでリング本体１２ｃを縮径させることができる。縮径することによって、スナップリング１２を第２支持部２２の内周面２２ｂに入れることができる。また、第２支持部２２の内周面２２ｂには、その他端側の開口部付近に周方向全周にわたって延びる取付溝２２ｃが形成されている。取付溝２２ｃに弾性復帰させたリング本体１２ｃの外縁部分を嵌め込むことで、第２支持部２２にスナップリング１２が内嵌めされる。 The snap ring 12 which is an example of the support auxiliary member is an inner fitting type snap ring. As shown in FIG. 2, the snap ring 12 is formed so as to be elastically deformable by a ring-shaped (more specifically, roughly C-shaped) washer in a plan view. Therefore, the diameter of the ring body 12c can be reduced by sandwiching the snap ring 12 so that both end portions 12a and 12b are brought close to each other. By reducing the diameter, the snap ring 12 can be inserted into the inner peripheral surface 22b of the second support portion 22. Further, on the inner peripheral surface 22b of the second support portion 22, a mounting groove 22c extending over the entire circumference in the circumferential direction is formed in the vicinity of the opening on the other end side. By fitting the outer edge portion of the ring body 12c elastically restored into the mounting groove 22c, the snap ring 12 is internally fitted into the second support portion 22.
　また、スナップリング１２では、一部分が径方向内側に凹んでおり、その部位が凹部１２ｄを形成している。本実施形態では、凹部１２ｄは、スナップリング１２の開口１２ｆから１８０度ずれた位置に形成されている。なお、開口１２ｆは、スナップリング１２の両端部１２ａ，１２ｂの間にある開いた口の部分である。また、凹部１２ｄが、例えばテーパ状に形成されており、径方向外側に向かうにつれて拡幅している。凹部１２ｄには、スナップリング１２が内嵌めされた状態で温度センサ３の残余部分３ｂ（より詳しくは第２被支持部３ｃ）が入る。そして、凹部１２ｄに入ることによって弾性復帰して拡径するリング本体１２ｃによって第２被支持部３ｃが内周面２２ｂに押し付けられている。即ち、第２被支持部３ｃは、凹部１２ｄと周方向において少なくとも２点又は面で接触して第２支持部２２に押し付けられて、少なくとも３点又は面で安定的に支持される。このようにして、温度センサ３が第１被支持部３ａ及び第１被支持部３ａと異なる第２被支持部３ｃの２点で支持される。即ち、温度センサ３は、第１被支持部３ａと少なくとも軸線方向に異なる位置にある、より詳しくは温度センサ３の中間部分にある第２被支持部３ｃの２点で支持される。 Further, in the snap ring 12, a part of the snap ring 12 is recessed inward in the radial direction, and the portion forms the recess 12d. In the present embodiment, the recess 12d is formed at a position displaced by 180 degrees from the opening 12f of the snap ring 12. The opening 12f is an open mouth portion between both end portions 12a and 12b of the snap ring 12. Further, the recess 12d is formed in a tapered shape, for example, and widens toward the outside in the radial direction. The remaining portion 3b (more specifically, the second supported portion 3c) of the temperature sensor 3 is inserted into the recess 12d with the snap ring 12 fitted inside. Then, the second supported portion 3c is pressed against the inner peripheral surface 22b by the ring body 12c that elastically returns and expands in diameter by entering the recess 12d. That is, the second supported portion 3c comes into contact with the recess 12d at at least two points or surfaces in the circumferential direction and is pressed against the second supporting portion 22, and is stably supported at at least three points or surfaces. In this way, the temperature sensor 3 is supported at two points, the first supported portion 3a and the second supported portion 3c, which is different from the first supported portion 3a. That is, the temperature sensor 3 is supported by two points of the second supported portion 3c located at least in the axial direction different from the first supported portion 3a, more specifically, in the intermediate portion of the temperature sensor 3.
　また、温度センサ３は、その中間部分、より詳しくは第２被支持部３ｃの一端側にフランジ３ｄが形成されている（図１の拡大図参照）。フランジ３ｄは、温度センサ３において半径方向外周に突出し、且つ温度センサ３の周方向全周にわたって形成されている。このような形状を有するフランジ３ｄの外縁形状は、凹部１２ｄの内縁形状より大きく形成されている。それ故、フランジ３ｄは、凹部１２ｄと係合し、温度センサ３が軸線方向において一端から他端に向かう方向の移動が規制される。また、フランジ３ｄは、取付溝２２ｃに入るようになっている。これにより、第２被支持部３ｃが内周面２２ｂに押し付けられる。これにより、温度センサ３が挿通孔２１ａから抜けることを防ぐことができる。なお、フランジ３ｄは、必ずしも全周に形成されている必要はない。即ち、フランジ３ｄは、周方向において少なくとも一部分に形成されていればよい。 Further, in the temperature sensor 3, a flange 3d is formed in the intermediate portion thereof, more specifically, on one end side of the second supported portion 3c (see the enlarged view of FIG. 1). The flange 3d protrudes to the outer periphery in the radial direction of the temperature sensor 3 and is formed over the entire circumference of the temperature sensor 3 in the circumferential direction. The outer edge shape of the flange 3d having such a shape is formed larger than the inner edge shape of the recess 12d. Therefore, the flange 3d engages with the recess 12d, and the temperature sensor 3 is restricted from moving from one end to the other in the axial direction. Further, the flange 3d is adapted to enter the mounting groove 22c. As a result, the second supported portion 3c is pressed against the inner peripheral surface 22b. This makes it possible to prevent the temperature sensor 3 from coming out of the insertion hole 21a. The flange 3d does not necessarily have to be formed on the entire circumference. That is, the flange 3d may be formed at least in a part in the circumferential direction.
　このように構成される支持構造１では、温度センサ３を２点で支持することによって、温度センサ３を長くしてもそれを安定して支持することができる。また、スナップリング１２を用いることによって、温度センサ３を簡易な構造で２点支持することができる。更に、温度センサ３が２点で支持されているので、一点で支持される場合に比べて温度センサ３の他端から支持点までの距離（即ち、他端から第２被支持部３ｃまでの距離）を短くすることができる。それ故、温度センサ３の固有振動数を高周波側へとシフトさせることができる。これにより、使用時において温度センサ３が低周波領域で振動した際、温度センサ３が共振することを抑制することができる。 In the support structure 1 configured in this way, by supporting the temperature sensor 3 at two points, it is possible to stably support the temperature sensor 3 even if the temperature sensor 3 is lengthened. Further, by using the snap ring 12, the temperature sensor 3 can be supported at two points with a simple structure. Further, since the temperature sensor 3 is supported at two points, the distance from the other end of the temperature sensor 3 to the support point (that is, from the other end to the second supported portion 3c) is as compared with the case where the temperature sensor 3 is supported at one point. Distance) can be shortened. Therefore, the natural frequency of the temperature sensor 3 can be shifted to the high frequency side. As a result, it is possible to prevent the temperature sensor 3 from resonating when the temperature sensor 3 vibrates in a low frequency region during use.
　このように構成される支持構造１では、第２被支持部３ｃが図１に示すように温度センサ３の中間部分に位置している。そして、スナップリング１２は、第２被支持部３ｃから温度センサ３の先端３ｅまでの長さが第１被支持部３ａと第２被支持部３ｃとの間の長さより大きくなるように配置されている。更に詳細に説明すると、第１被支持部３ａから第２被支持部３ｃまでの長さＬ１と、第２被支持部３ｃから温度センサ３の先端３ｅまでの長さＬ２との比が例えばＬ１：Ｌ２＝１：α（αは４以上１５以下）となっている。なお、長さＬ１と長さＬ２との比は、好ましくはＬ１：Ｌ２＝１：７である。このような比率にすることによって、温度センサ３の先端３ｅを第２被支持部３ｃからより離れた位置に配置しつつ温度センサ３を安定的に支持することができる。また、温度センサ３の固有振動数を高周波側へとシフトさせることができる。 In the support structure 1 configured in this way, the second supported portion 3c is located in the intermediate portion of the temperature sensor 3 as shown in FIG. The snap ring 12 is arranged so that the length from the second supported portion 3c to the tip 3e of the temperature sensor 3 is larger than the length between the first supported portion 3a and the second supported portion 3c. ing. More specifically, the ratio of the length L1 from the first supported portion 3a to the second supported portion 3c and the length L2 from the second supported portion 3c to the tip 3e of the temperature sensor 3 is, for example, L1. : L2 = 1: α (α is 4 or more and 15 or less). The ratio of the length L1 to the length L2 is preferably L1: L2 = 1: 7. With such a ratio, the temperature sensor 3 can be stably supported while the tip 3e of the temperature sensor 3 is arranged at a position further away from the second supported portion 3c. Further, the natural frequency of the temperature sensor 3 can be shifted to the high frequency side.
　また、支持構造１では、凹部１２ｄが第２被支持部３ｃの外周面に接触しているので、第２被支持部３ｃの径方向の動きを規制することができる。それ故、第２被支持部３ｃを更に安定的に支持することができる。これにより、第１被支持部３ａに作用する荷重を低減することができる。また、支持構造１では、スナップリング１２を縮径させるように弾性変形させて第２支持部２２に入れることによって内嵌めすることができるので、温度センサ３を簡単に支持することができる。また、スナップリング１２を用いることによって、温度センサ３の２点支持を簡単に実現することができる。 Further, in the support structure 1, since the recess 12d is in contact with the outer peripheral surface of the second supported portion 3c, the radial movement of the second supported portion 3c can be regulated. Therefore, the second supported portion 3c can be supported more stably. As a result, the load acting on the first supported portion 3a can be reduced. Further, in the support structure 1, the snap ring 12 can be elastically deformed so as to reduce the diameter and inserted into the second support portion 22, so that the temperature sensor 3 can be easily supported. Further, by using the snap ring 12, it is possible to easily realize the two-point support of the temperature sensor 3.
　［第２実施形態］
　第２実施形態の支持構造１Ａは、第１実施形態の支持構造１と構成が類似している。従って、第２実施形態の支持構造１Ａの構成については、主に第１実施形態の支持構造１と異なる点について説明し、同一の構成については同一の符号を付して説明を省略する。第３及び第４実施形態の支持構造１Ｂ，１Ｃについても同様である。 [Second Embodiment]
The support structure 1A of the second embodiment has a structure similar to that of the support structure 1 of the first embodiment. Therefore, the configuration of the support structure 1A of the second embodiment will be mainly described as being different from the support structure 1 of the first embodiment, and the same configuration will be designated by the same reference numerals and description thereof will be omitted. The same applies to the support structures 1B and 1C of the third and fourth embodiments.
　第２実施形態の支持構造１Ａは、図３に示すように基体１１と、スナップリング１２Ａとを備えている。スナップリング１２Ａは、内嵌め型のスナップリングである。本実施形態において、スナップリング１２Ａは、図４に示すように平面視で大略Ｃ形状に形成されている。更に詳細に説明すると、スナップリング１２Ａは、大略短冊状の板バネによって形成され、その両端部１２ａ，１２ｂを折り返し且つ中間部分を大略Ｃ形状に曲げることによって弾性変形可能に形成されている。即ち、スナップリング１２Ａは、第１実施形態のスナップリング１２と同様にその両端部１２ａ，１２ｂを近づけるように挟むことによって縮径させることができる。そして、スナップリング１２Ａは、縮径させることによって第２支持部２２の取付溝２２ｃに入れることができる。また、スナップリング１２Ａには、テーパ状の凹部１２ｄが形成されている。凹部１２ｄには、第２被支持部３ｃが入る。それ故、第２被支持部３ｃは、弾性復帰して拡径するスナップリング１２Ａによって内周面２２ｂに押し付けられる。これにより、温度センサ３が第１被支持部３ａ及び第２被支持部３ｃの２点で支持される。 The support structure 1A of the second embodiment includes a base 11 and a snap ring 12A as shown in FIG. The snap ring 12A is an inner fitting type snap ring. In the present embodiment, the snap ring 12A is formed in a substantially C shape in a plan view as shown in FIG. More specifically, the snap ring 12A is formed by a roughly strip-shaped leaf spring, and is formed so as to be elastically deformable by folding back both end portions 12a and 12b and bending the intermediate portion into a roughly C shape. That is, the diameter of the snap ring 12A can be reduced by sandwiching both end portions 12a and 12b so as to be close to each other, similarly to the snap ring 12 of the first embodiment. Then, the snap ring 12A can be inserted into the mounting groove 22c of the second support portion 22 by reducing the diameter. Further, the snap ring 12A is formed with a tapered recess 12d. The second supported portion 3c is inserted in the recess 12d. Therefore, the second supported portion 3c is pressed against the inner peripheral surface 22b by the snap ring 12A that elastically returns and expands in diameter. As a result, the temperature sensor 3 is supported at two points, the first supported portion 3a and the second supported portion 3c.
　このよう構成される支持構造１Ａは、板バネを曲げることによってスナップリング１２Ａを構成することができる。それ故、温度センサ３を容易に支持することができる。その他、第２実施形態の支持構造１Ａは、第１実施形態の支持構造１と同様の作用効果を奏する。 The support structure 1A configured in this way can form the snap ring 12A by bending the leaf spring. Therefore, the temperature sensor 3 can be easily supported. In addition, the support structure 1A of the second embodiment has the same effect as that of the support structure 1 of the first embodiment.
　［第３実施形態］
　第３実施形態の支持構造１Ｂは、図５に示すように基体１１Ｂと、スナップリング１２Ｂとを備えている。基体１１Ｂは、共に大略円柱状に形成される第１支持部２１及び第２支持部２２Ｂを有している。第２支持部２２Ｂは、第１支持部２１と一体的に形成されている。そして、第２支持部２２Ｂは、挿通孔２１ａに対応する位置に切欠き２２ｄを有している。即ち、切欠き２２ｄは、第２支持部２２Ｂの外周面に軸線方向に貫通するように形成されている。更に、切欠き２２ｄは、径方向外方に開口するように平面視でＵ字状に形成されている。切欠き２２ｄには、温度センサ３の残余部分３ｂが挿通されている。そして、残余部分３ｂは、切欠き２２ｄから径方向外方に表出している。また、第２支持部２２Ｂの外周面には、周方向全周にわたって取付溝２２ｅが形成され、そこにスナップリング１２Ｂが外嵌めされている。 [Third Embodiment]
The support structure 1B of the third embodiment includes a base 11B and a snap ring 12B as shown in FIG. The substrate 11B has a first support portion 21 and a second support portion 22B, both of which are formed in a substantially columnar shape. The second support portion 22B is integrally formed with the first support portion 21. The second support portion 22B has a notch 22d at a position corresponding to the insertion hole 21a. That is, the notch 22d is formed so as to penetrate the outer peripheral surface of the second support portion 22B in the axial direction. Further, the notch 22d is formed in a U shape in a plan view so as to open outward in the radial direction. The remaining portion 3b of the temperature sensor 3 is inserted through the notch 22d. The remaining portion 3b is exposed outward in the radial direction from the notch 22d. Further, a mounting groove 22e is formed on the outer peripheral surface of the second support portion 22B over the entire circumference in the circumferential direction, and the snap ring 12B is externally fitted therein.
　スナップリング１２Ｂは、いわゆる外嵌め型のスナップリングであり、図６に示すような大略Ｅ形のワッシャーで弾性変形可能に形成されている。即ち、スナップリング１２Ｂは、その開口１２ｆが取付溝２２ｅの径より小さい。それ故、スナップリング１２を開口１２ｆから取付溝２２ｅに差し込むと、スナップリング１２自身が拡径する。そして、スナップリング１２を押し込んでいくと、やがてスナップリング１２が縮径するように弾性復帰して第２支持部２２Ｂに外嵌めされる。また、スナップリング１２Ｂは、突起部１２ｅを有している。突起部１２ｅは、スナップリング１２Ｂの周方向中間部分において径方向内方に突出するように形成されている。また、突起部１２ｅの先端部分には、凹部１２ｄが形成されている。凹部１２ｄには、温度センサ３の第２被支持部３ｃが入れられる。即ち、第２被支持部３ｃが部分的に切欠き２２ｄからはみ出ており、その部分が凹部１２ｄに入っている。凹部１２ｄは、径方向外方に進むにつれて先細りの大略テーパ状に形成されている。それ故、弾性復帰して縮径したスナップリング１２Ｂは、第２支持部２２Ｂに外嵌めされている状態で凹部１２ｄによって第２被支持部３ｃを第２支持部２２Ｂの外周面に押し付ける。これにより、温度センサ３は、第１被支持部３ａ及び第２被支持部３ｃの２点で支持される。 The snap ring 12B is a so-called outer fitting type snap ring, and is formed so as to be elastically deformable with a roughly E-shaped washer as shown in FIG. That is, the opening 12f of the snap ring 12B is smaller than the diameter of the mounting groove 22e. Therefore, when the snap ring 12 is inserted into the mounting groove 22e through the opening 12f, the diameter of the snap ring 12 itself expands. Then, as the snap ring 12 is pushed in, the snap ring 12 is elastically restored so as to shrink in diameter and is externally fitted to the second support portion 22B. Further, the snap ring 12B has a protrusion 12e. The protrusion 12e is formed so as to project inward in the radial direction at the circumferential intermediate portion of the snap ring 12B. Further, a recess 12d is formed at the tip of the protrusion 12e. The second supported portion 3c of the temperature sensor 3 is inserted into the recess 12d. That is, the second supported portion 3c partially protrudes from the notch 22d, and that portion is contained in the recess 12d. The recess 12d is formed in a substantially tapered shape that tapers toward the outside in the radial direction. Therefore, the snap ring 12B elastically restored and reduced in diameter presses the second supported portion 3c against the outer peripheral surface of the second supporting portion 22B by the concave portion 12d in a state of being externally fitted to the second supporting portion 22B. As a result, the temperature sensor 3 is supported at two points, the first supported portion 3a and the second supported portion 3c.
　このように構成される支持構造１では、スナップリング１２Ｂの中に第２支持部２２Ｂを差し込んでスナップリング１２Ｂを外嵌めすることによって、温度センサ３を簡単に支持することができる。また、スナップリング１２Ｂを用いることによって、温度センサ３の２点支持を簡単に実現することができる。その他、第３実施形態の支持構造１Ｂは、第１実施形態の支持構造１と同様の作用効果を奏する。 In the support structure 1 configured in this way, the temperature sensor 3 can be easily supported by inserting the second support portion 22B into the snap ring 12B and fitting the snap ring 12B externally. Further, by using the snap ring 12B, the two-point support of the temperature sensor 3 can be easily realized. In addition, the support structure 1B of the third embodiment has the same effect as that of the support structure 1 of the first embodiment.
　［第４実施形態］
　第４実施形態の支持構造１Ｃは、図７に示すように基体１１Ｃと、スナップリング１２Ｃとを備えている。基体１１Ｃは、共に大略円柱状に形成される第１支持部２１及び第２支持部２２Ｃを有している。第２支持部２２Ｃもまた、第１支持部２１と一体的に形成されている。そして、第２支持部２２Ｃは、挿通孔２１ａに対応する位置に切欠き２２ｄを有している。切欠き２２ｄからは、残余部分３ｂの一部、本実施形態において大略半円部分がはみ出ている。また、スナップリング１２Ｃは、第２被支持部３ｃを第２支持部２２Ｃに押し付けるべく第２支持部２２Ｃに外嵌めされている。 [Fourth Embodiment]
The support structure 1C of the fourth embodiment includes a substrate 11C and a snap ring 12C as shown in FIG. The substrate 11C has a first support portion 21 and a second support portion 22C, both of which are formed in a substantially columnar shape. The second support portion 22C is also integrally formed with the first support portion 21. The second support portion 22C has a notch 22d at a position corresponding to the insertion hole 21a. A part of the remaining portion 3b and a substantially semicircular portion in the present embodiment protrude from the notch 22d. Further, the snap ring 12C is externally fitted to the second support portion 22C so as to press the second supported portion 3c against the second support portion 22C.
　スナップリング１２Ｃは、いわゆる外嵌め型のスナップリングである。本実施形態において、スナップリング１２Ｃは、図８に示すような大略半円形のワッシャーで弾性変形可能に形成されている。スナップリング１２Ｃは、その両端部１２ａ，１２ｂを離すように拡径させてその中に第２支持部２２Ｃを入れる。そして、スナップリング１２Ｃを押し進めていくと、やがてスナップリング１２Ｃが弾性復帰して縮径する。これにより、スナップリング１２Ｃが第２支持部２２Ｂに外嵌めされる。また、スナップリング１２Ｃは、その両端部１２ａ，１２ｂに爪部１２ｇ，１２ｈを有している。爪部１２ｇ，１２ｈは、径方向内方に突出している。更に、第２支持部２２Ｃの外周面には、爪部１２ｇ，１２ｈの各々に対応する位置に係合孔２２ｆ，２２ｇが形成されている。係合孔２２ｆ，２２ｇの各々には、対応する爪部１２ｇ，１２ｈが入れられて係合されている。これにより、スナップリング１２Ｃの脱落を防止することができる。 The snap ring 12C is a so-called outer fitting type snap ring. In the present embodiment, the snap ring 12C is formed so as to be elastically deformable by a washer having a substantially semicircular shape as shown in FIG. The diameter of the snap ring 12C is increased so that both end portions 12a and 12b are separated from each other, and the second support portion 22C is inserted therein. Then, as the snap ring 12C is pushed forward, the snap ring 12C elastically returns and the diameter is reduced. As a result, the snap ring 12C is externally fitted to the second support portion 22B. Further, the snap ring 12C has claw portions 12g and 12h at both end portions 12a and 12b thereof. The claw portions 12g and 12h project inward in the radial direction. Further, on the outer peripheral surface of the second support portion 22C, engagement holes 22f and 22g are formed at positions corresponding to the claw portions 12g and 12h, respectively. Corresponding claw portions 12g and 12h are inserted into and engaged with the engaging holes 22f and 22g, respectively. This makes it possible to prevent the snap ring 12C from falling off.
　また、スナップリング１２Ｃは、リング本体１２ｃの内周縁に複数の切欠きが形成されている。本実施形態においてリング本体１２ｃには、３つの凹部１２ｉ～１２ｋが形成されており、凹部１２ｉ～１２ｋによってリング本体１２ｃが弾性変形し易く（より詳しくは、拡径し易く）なっている。また、凹部１２ｉ～１２ｋのうちの１つ、本実施形態において真ん中の凹部１２ｊは、第２被支持部３ｃに対応させて形成され、且つ径方向外方に進むにつれて先細りの大略テーパ状に形成されている。それ故、スナップリング１２Ｂを第２支持部２２Ｂに外嵌めすると、凹部１２ｊの中に第２被支持部３ｃが入る。これにより、スナップリング１２Ｃが弾性復帰して縮径すると、第２被支持部３ｃが第２支持部２２Ｃの外周面に押し付けられる。これにより、温度センサ３は、第１被支持部３ａ及び第２被支持部３ｃの２点で支持される。 Further, the snap ring 12C has a plurality of notches formed on the inner peripheral edge of the ring body 12c. In the present embodiment, three recesses 12i to 12k are formed in the ring body 12c, and the ring body 12c is easily elastically deformed by the recesses 12i to 12k (more specifically, the diameter is easily expanded). Further, one of the recesses 12i to 12k, the recess 12j in the middle in the present embodiment, is formed so as to correspond to the second supported portion 3c, and is formed in a substantially tapered shape that tapers outward in the radial direction. Has been done. Therefore, when the snap ring 12B is externally fitted to the second support portion 22B, the second supported portion 3c is inserted into the recess 12j. As a result, when the snap ring 12C elastically returns and the diameter is reduced, the second supported portion 3c is pressed against the outer peripheral surface of the second supporting portion 22C. As a result, the temperature sensor 3 is supported at two points, the first supported portion 3a and the second supported portion 3c.
　このように構成される支持構造１Ｃでは、スナップリング１２Ｃのリング本体１２ｃが拡径されてその中に第２支持部２２Ｃが差し込まれる。そして、スナップリング１２Ｃを弾性復帰させることによって、スナップリング１２Ｃが外嵌めされる。それ故、スナップリング１２Ｃの取付けが容易であるので、温度センサ３を簡単に支持することができる。また、スナップリング１２Ｃを用いることによって、温度センサ３の２点支持を簡単に実現することができる。その他、第４実施形態の支持構造１Ｃは、第３実施形態の支持構造１Ｃと同様の作用効果を奏する。 In the support structure 1C configured in this way, the ring body 12c of the snap ring 12C is expanded in diameter, and the second support portion 22C is inserted therein. Then, by elastically returning the snap ring 12C, the snap ring 12C is externally fitted. Therefore, since the snap ring 12C can be easily attached, the temperature sensor 3 can be easily supported. Further, by using the snap ring 12C, the two-point support of the temperature sensor 3 can be easily realized. In addition, the support structure 1C of the fourth embodiment has the same effect as that of the support structure 1C of the third embodiment.
　＜第１実施例＞
　以下では、支持構造１が適用される実施形態の一例、即ち図９に示すようなタンクバルブ２について説明する。なお、タンクバルブ２の構成については、前述する支持構造１の構成については、前述する構成と同一の符号を付し、その詳しい説明は省略する。後述する第２実施例のタンクバルブ２Ｂについても同様である。 <First Example>
Hereinafter, an example of the embodiment to which the support structure 1 is applied, that is, the tank valve 2 as shown in FIG. 9 will be described. Regarding the configuration of the tank valve 2, the configuration of the support structure 1 described above is designated by the same reference numerals as the configuration described above, and detailed description thereof will be omitted. The same applies to the tank valve 2B of the second embodiment described later.
　第１実施例のタンクバルブ２は、圧力容器、例えば高圧タンク容器（以下、単に「タンク容器」という）４に設けられる。そして、タンクバルブ２は、タンク容器４の中に貯留されるガス、例えば水素及びＬＮＧ等のガスの排出等を制御する。タンクバルブ２は、バルブブロック２ａと複数の弁によって構成されている。タンクバルブ２の一部分がタンク容器４の口部４ａに差し込まれている。また、タンクバルブ２は、例えばインタンク型のバルブである。即ち、タンクバルブ２は、口部４ａに差し込まれている部分に電磁弁５が取り付けられている。また、電磁弁５は、第１実施形態の支持構造１を有している。そして、電磁弁５には、支持構造１によって棒状部材である温度センサ３が取り付けられている。 The tank valve 2 of the first embodiment is provided in a pressure vessel, for example, a high pressure tank container (hereinafter, simply referred to as “tank container”) 4. Then, the tank valve 2 controls the discharge of gas stored in the tank container 4, such as hydrogen and gas such as LNG. The tank valve 2 is composed of a valve block 2a and a plurality of valves. A part of the tank valve 2 is inserted into the mouth portion 4a of the tank container 4. Further, the tank valve 2 is, for example, an in-tank type valve. That is, the solenoid valve 5 is attached to the portion of the tank valve 2 that is inserted into the mouth portion 4a. Further, the solenoid valve 5 has the support structure 1 of the first embodiment. A temperature sensor 3 which is a rod-shaped member is attached to the solenoid valve 5 by a support structure 1.
　即ち、電磁弁５は、第１支持部２１に対応する固定磁極３１と第２支持部２２に対応する蓋体３２とを有している。本実施例では、固定磁極３１は、口部４ａの内部に配置されている。また、固定磁極３１は、バルブブロック２ａのうち、タンク容器４の内側（中心部）寄りに配置されている。詳細には、固定磁極３１は、タンクバルブ２のバルブブロック２ａの開口部２ｂに収容されている。また、蓋体３２は、固定磁極３１よりタンク容器４の内側に配置されている。蓋体３２は、開口部２ｂに固定されている。そして、蓋体３２は、バルブブロック２ａの内周面に形成される内向きフランジ２ｃに固定磁極３１を押し付けて挟持している。また、固定磁極３１には、挿通孔２１ａが形成されている。そして、挿通孔２１ａには、温度センサ３の一端側部分、即ち第１被支持部３ａが挿入されて支持されている。また、挿通孔２１ａは、平面視で蓋体３２の内周面２２ｂに内接するように形成されている。そして、挿通孔２１ａから延びる温度センサ３の残余部分３ｂは、蓋体３２の内周面２２ｂに沿うように延在している。また、蓋体３２の内周面２２ｂには、スナップリング１２が内嵌めされている。これにより、スナップリング１２と第２支持部２２とによって第２被支持部３ｃが支持されている。このようにして、タンクバルブ２では、支持構造１によって温度センサ３が２点で支持されている。 That is, the solenoid valve 5 has a fixed magnetic pole 31 corresponding to the first support portion 21 and a lid 32 corresponding to the second support portion 22. In this embodiment, the fixed magnetic pole 31 is arranged inside the mouth portion 4a. Further, the fixed magnetic pole 31 is arranged closer to the inside (center portion) of the tank container 4 in the valve block 2a. Specifically, the fixed magnetic pole 31 is housed in the opening 2b of the valve block 2a of the tank valve 2. Further, the lid 32 is arranged inside the tank container 4 from the fixed magnetic pole 31. The lid 32 is fixed to the opening 2b. The lid 32 presses the fixed magnetic pole 31 against the inward flange 2c formed on the inner peripheral surface of the valve block 2a and sandwiches the lid 32. Further, an insertion hole 21a is formed in the fixed magnetic pole 31. Then, one end side portion of the temperature sensor 3, that is, the first supported portion 3a is inserted and supported in the insertion hole 21a. Further, the insertion hole 21a is formed so as to be inscribed in the inner peripheral surface 22b of the lid 32 in a plan view. The remaining portion 3b of the temperature sensor 3 extending from the insertion hole 21a extends along the inner peripheral surface 22b of the lid 32. Further, a snap ring 12 is internally fitted on the inner peripheral surface 22b of the lid body 32. As a result, the second supported portion 3c is supported by the snap ring 12 and the second supporting portion 22. In this way, in the tank valve 2, the temperature sensor 3 is supported at two points by the support structure 1.
　このように構成されるタンクバルブ２は、第１実施形態の支持構造１と同様に構成されている。それ故、温度センサ３は、先端３ｅを固定磁極３１よりタンク容器４の内側へと位置させることができる。また、先端３ｅと第２被支持部３ｃとの間の長さが第１被支持部３ａと第２被支持部３ｃとの間の長さより大きくすることができる。それ故、温度センサ３の先端３ｅをタンク容器４内においてより内側に配置しつつ、温度センサ３を安定的に支持することができる。即ち、長くなった温度センサ３を安定的に支持することができる。また、温度センサ３を２点で支持することによって温度センサ３の固有振動数を高周波側へとシフトさせることができる。これにより、タンクバルブ２をタンク容器４に搭載した際に生じる低周波領域の振動に対して温度センサ３が共振することを抑制することができる。その他、タンクバルブ２は、支持構造１が奏する作用効果を奏する。 The tank valve 2 configured in this way is configured in the same manner as the support structure 1 of the first embodiment. Therefore, the temperature sensor 3 can position the tip 3e from the fixed magnetic pole 31 to the inside of the tank container 4. Further, the length between the tip 3e and the second supported portion 3c can be made larger than the length between the first supported portion 3a and the second supported portion 3c. Therefore, the temperature sensor 3 can be stably supported while the tip 3e of the temperature sensor 3 is arranged inside the tank container 4. That is, the lengthened temperature sensor 3 can be stably supported. Further, by supporting the temperature sensor 3 at two points, the natural frequency of the temperature sensor 3 can be shifted to the high frequency side. As a result, it is possible to suppress the temperature sensor 3 from resonating with respect to the vibration in the low frequency region that occurs when the tank valve 2 is mounted on the tank container 4. In addition, the tank valve 2 has the effect of the support structure 1.
　＜第２実施例＞
　第２実例のタンクバルブ２Ｂは、第１実施例のタンクバルブ２と構成が類似している。従って、第２実施例のタンクバルブ２Ｂの構成については、主に第１実施例のタンクバルブ２と異なる点について説明し、同一の構成については同一の符号を付して説明を省略する。 <Second Example>
The tank valve 2B of the second embodiment has a configuration similar to that of the tank valve 2 of the first embodiment. Therefore, the configuration of the tank valve 2B of the second embodiment will be mainly described as being different from the tank valve 2 of the first embodiment, and the same configuration will be designated by the same reference numerals and description thereof will be omitted.
　第２実施例のタンクバルブ２Ｂは、例えばオンタンク型のバルブである。即ち、電磁弁がタンク容器４の外側に配置されている。このように構成されるタンクバルブ２Ｂは、例えば基体１１Ｂ及び蓋体３２を有している。基体１１Ｂは、タンクバルブ２のバルブブロック２ａの開口部２ｂに収容されている。また、蓋体３２は、基体１１Ｂよりタンク容器４の内側に配置されて開口部２ｂに螺合され、基体１１Ｂをバルブブロック２ａの内周面に形成される内向きフランジ２ｃに押し付けて挟持している。基体１１Ｂは、第１支持部２１と第２支持部２２Ｂを有している。また、第１支持部２１には、温度センサ３の第１被支持部３ａが支持されている。そして、第２支持部２２Ｂの切欠き２２ｄに残余部が挿通されている。更に、第２支持部２２Ｂには、第２被支持部３ｃに対応する位置にてスナップリング１２Ｂが外嵌めされている。これにより、弾性復帰して縮径したスナップリング１２Ｂと第２支持部２２Ｂとによって第２被支持部３ｃが支持されている。このようにして、タンクバルブ２Ｂでは、支持構造１Ｂによって温度センサ３が２点で支持されている。 The tank valve 2B of the second embodiment is, for example, an on-tank type valve. That is, the solenoid valve is arranged on the outside of the tank container 4. The tank valve 2B configured in this way has, for example, a base 11B and a lid 32. The substrate 11B is housed in the opening 2b of the valve block 2a of the tank valve 2. Further, the lid 32 is arranged inside the tank container 4 from the base 11B and screwed into the opening 2b, and the base 11B is pressed against the inward flange 2c formed on the inner peripheral surface of the valve block 2a to be sandwiched. ing. The substrate 11B has a first support portion 21 and a second support portion 22B. Further, the first supported portion 3a of the temperature sensor 3 is supported by the first supported portion 21. Then, the remaining portion is inserted through the notch 22d of the second support portion 22B. Further, a snap ring 12B is externally fitted to the second support portion 22B at a position corresponding to the second supported portion 3c. As a result, the second supported portion 3c is supported by the snap ring 12B and the second supporting portion 22B that have been elastically restored and the diameter has been reduced. In this way, in the tank valve 2B, the temperature sensor 3 is supported at two points by the support structure 1B.
　このように構成されるタンクバルブ２は、第１実施例のタンクバルブ２と同様の作用効果を奏し、また支持構造１Ｂが奏する作用効果を奏する。 The tank valve 2 configured in this way has the same effect as that of the tank valve 2 of the first embodiment, and also has the effect of the support structure 1B.
