Description

本発明は、電子部品用ケースおよび前記電子部品用ケースを用いたセンサ装置に関し、特に、取り付けられる対象物との当接箇所の変形量を抑えた電子部品用ケースおよび前記電子部品用ケースを用いたセンサ装置に関するものである。   The present invention relates to an electronic component case and a sensor device using the electronic component case, and in particular, uses the electronic component case and the electronic component case in which the amount of deformation at a contact point with an object to be attached is suppressed. The present invention relates to a sensor device.

昨今、自動車や２輪車では車両を電子制御するために様々な箇所の位置検出や角度検出などを行なうセンサ類が自動車内や２輪車には配置されている。   In recent years, in automobiles and two-wheeled vehicles, sensors for detecting the position and angle of various locations in order to electronically control the vehicle are arranged in the automobile and two-wheeled vehicles.

特にバルブの開閉角度を検知するセンサとして用いられる場合、バルブの回転軸に直接取り付けられることもある。仮に、バルブとセンサ装置の取り付け部からバルブ内を流れる流体が漏れると、実際にバルブ内を流れている流体の流量とセンサの検知結果から割り出した流量との間に大きな誤差が生じ、正しい制御ができなくなる。したがって、バルブとセンサ装置の取り付け部はできるだけ平面度が高く、取り付けた際に取り付け部と車体との間の気密性のよい電子部品用ケースを有したセンサ装置が求められている。   In particular, when used as a sensor for detecting the opening / closing angle of a valve, it may be directly attached to the rotating shaft of the valve. If the fluid flowing in the valve leaks from the valve and sensor mounting part, a large error will occur between the flow rate of the fluid actually flowing in the valve and the flow rate calculated from the detection result of the sensor. Can not be. Therefore, a sensor device having a highly airtight case for electronic parts between the mounting portion and the vehicle body when the mounting portion of the valve and the sensor device is as flat as possible.

また、昨今はセンサ装置の小型化の要望が高まっている。   Recently, there is an increasing demand for downsizing of the sensor device.

このような小型で気密性のある電子部品用ケースを有したセンサ装置としては、下記の特許文献１に記載のセンサ装置が知られている。   As a sensor device having such a small and airtight case for electronic parts, a sensor device described in Patent Document 1 below is known.

以下、図５および図６を用いて、特許文献１に記載のセンサ装置について説明する。図５は特許文献１に記載のセンサ装置ＳＥを２輪車車体ＭＣに取り付けた状態を示す図であり、図６はケースＣＡの反りの傾向を示す図である。   Hereinafter, the sensor device described in Patent Document 1 will be described with reference to FIGS. 5 and 6. FIG. 5 is a view showing a state where the sensor device SE described in Patent Document 1 is attached to the two-wheeled vehicle body MC, and FIG. 6 is a view showing a tendency of warping of the case CA.

特許文献１に記載のセンサ装置ＳＥは、図５に示すように、２輪車の動作部ＭＭの動きを検知可能なセンサユニットＳＵと、センサユニットＳＵを内部に収納し２輪車車体ＭＣと当接しセンサ装置ＳＥを２輪車車体ＭＣに保持するケースＣＡと、を備えている。   As shown in FIG. 5, the sensor device SE described in Patent Document 1 includes a sensor unit SU that can detect the movement of the operation unit MM of a two-wheeled vehicle, a sensor unit SU that is housed therein, and a two-wheeled vehicle body MC. A case CA that abuts and holds the sensor device SE on the two-wheeled vehicle body MC.

特開２００２−１８８４８３号公報JP 2002-188383 A

特許文献１に記載のセンサ装置ＳＥは、従来の用途において機械的な性能や電気的な性能において特に課題はない。しかしながら、箱状に形成された合成樹脂材でできた成形部品は内部方向に凸になるように反りやすい傾向があるため、センサ装置ＳＥのケースＣＡの２輪車車体に当接する面がケースＣＡの内部方向に凸になるように反りやすい傾向がある。また、センサ装置ＳＥの小型化に対応するためにケースＣＡを低背化し固定箇所削減などをしたことで、図６に示すように、ケースＣＡの２輪車車体に当接する面はさらにケースＣＡの内部方向に凸になるように反りやすい傾向がある。仮に前記のような反りが発生した場合には２輪車車体ＭＣに当接する面と２輪車車体ＭＣとの間に隙間ＣＬができてしまい気密性が低下し、検知対象によっては内部を流れる流体の漏れが発生する可能性がある。   The sensor device SE described in Patent Document 1 has no particular problem in mechanical performance and electrical performance in conventional applications. However, since a molded part made of a synthetic resin material formed in a box shape tends to warp so as to protrude in the inner direction, the surface of the sensor device SE that contacts the two-wheeled vehicle body of the case CA is the case CA. There is a tendency to warp so as to be convex in the inner direction. Further, as shown in FIG. 6, the surface of the case CA that contacts the two-wheeled vehicle body is further reduced to the case CA by reducing the height of the case CA and reducing the number of fixing points in order to cope with the downsizing of the sensor device SE. There is a tendency to warp so as to be convex in the inner direction. If the warp as described above occurs, a gap CL is formed between the surface contacting the two-wheeled vehicle body MC and the two-wheeled vehicle body MC, and the airtightness is lowered. Fluid leakage may occur.

本発明は、上述した課題を解決して、小型でありながらも２輪車車体に当接する面の平面度が高く、２輪車車体に当接する面と２輪車車体との間の気密性がより安定したセンサ装置を提供するものである。   The present invention solves the above-described problems, and the flatness of the surface that contacts the two-wheeled vehicle body is high while being small, and the airtightness between the surface that contacts the two-wheeled vehicle body and the two-wheeled vehicle body is high. Provides a more stable sensor device.

［第１実施形態］
以下に第１実施形態における電子部品用ケース１１（以下、ケース１１と記す）について、図１および図２を用いて説明する。図１はケース１１を示す図であり、図１（ａ）はケース１１を上面側から示した図であり、図１（ｂ）はケース１１を底面側から示した図である。図２はリブ１１ｅを示す図である。 [First Embodiment]
Hereinafter, an electronic component case 11 (hereinafter referred to as case 11) in the first embodiment will be described with reference to FIGS. FIG. 1 is a view showing the case 11, FIG. 1 (a) is a view showing the case 11 from the upper surface side, and FIG. 1 (b) is a view showing the case 11 from the bottom surface side. FIG. 2 is a view showing the rib 11e.

ケース１１は、図１（ａ）、図１(ｂ)および図２に示すように、合成樹脂材により略直方体状に形成されており、ケース１１の底面であり被検知体ＴＶ（図４参照）の所定の面に当接する当接面１１ａと、当接面１１ａの外周を囲うように当接面１１ａの裏面方向に突出して形成された側壁１１ｂと、内部に別の部品を配置可能な貫通孔１１ｃと、ねじＳＣ（図４参照）を挿通可能なねじ止め部１１ｄと、を有している。   As shown in FIG. 1A, FIG. 1B, and FIG. 2, the case 11 is formed in a substantially rectangular parallelepiped shape from a synthetic resin material, and is the bottom surface of the case 11 and is the object to be detected TV (see FIG. 4). ), A side wall 11b formed so as to protrude from the back surface of the contact surface 11a so as to surround the outer periphery of the contact surface 11a, and another component can be disposed inside. It has a through hole 11c and a screwing portion 11d through which a screw SC (see FIG. 4) can be inserted.

貫通孔１１ｃは当接面１１ａから当接面１１ａの裏面まで貫通して円筒状に設けられている。なお、本実施形態においては貫通孔１１ｃは円筒形状としているが、その限りではない。   The through-hole 11c penetrates from the contact surface 11a to the back surface of the contact surface 11a and is provided in a cylindrical shape. In addition, in this embodiment, although the through-hole 11c is made into the cylindrical shape, it is not the limitation.

ねじ止め部１１ｄは、貫通孔１１ｃの中心点を対称中心として点対称となる一対の位置に設けられ、ねじＳＣを挿通可能な大きさに形成されている。   The screwing portions 11d are provided at a pair of positions that are point-symmetric with respect to the center point of the through-hole 11c, and have a size that allows the screw SC to be inserted therethrough.

また、当接面１１ａには、挿通孔１１ｃの中心とねじ止め部１１ｄの中心を結ぶ仮想直線ＩＬ１上と、仮想直線ＩＬ１を対称軸として線対称となる一対の仮想直線ＩＬ２および仮想直線ＩＬ３とに沿ってそれぞれリブ１１ｅを形成されている。   Further, on the contact surface 11a, a virtual straight line IL1 connecting the center of the insertion hole 11c and the center of the screwing portion 11d, and a pair of virtual straight lines IL2 and IL3 that are symmetric with respect to the virtual straight line IL1 as an axis of symmetry, A rib 11e is formed along each.

なお、本実施形態においては、仮想直線ＩＬ１を対称軸として線対称となる一対の仮想直線ＩＬ２および仮想直線ＩＬ３は、挿通孔１１ｃの円周とねじ止め部１１ｄの円周との両方に接する直線である。   In the present embodiment, the pair of virtual straight lines IL2 and IL3 that are line symmetric with respect to the virtual straight line IL1 are the straight lines that are in contact with both the circumference of the insertion hole 11c and the circumference of the screwing portion 11d. It is.

以下、本実施形態としたことによる効果について説明する。   Hereinafter, the effect by having set it as this embodiment is demonstrated.

本実施形態の電子部品用樹脂ケースでは、対象物へ固定可能に形成された電子部品用樹脂ケースにおいて、別部品を挿通可能な挿通孔１１ｃと取り付け用のねじ止め部１１ｄとを備え、対象物と当接する当接面１１ａを底面とし、ねじ止め部１１ｄは挿通孔１１ｃの中心点に対して点対称の位置に一対設け、底面において、挿通孔１１ｃの中心とねじ止め部１１ｄの中心を結ぶ仮想直線ＩＬ１上と、仮想直線ＩＬ１を対称軸として線対称となる一対の仮想直線ＩＬ２上と仮想直線ＩＬ３上とにそれぞれリブ１１ｅを形成する構造とした。   In the resin case for electronic parts of the present embodiment, the resin case for electronic parts formed so as to be fixed to the object includes an insertion hole 11c through which another part can be inserted and a screwing part 11d for attachment. A pair of screwing portions 11d are provided at point-symmetrical positions with respect to the center point of the insertion hole 11c, and the bottom surface connects the center of the insertion hole 11c and the center of the screwing portion 11d. The ribs 11e are formed on the imaginary straight line IL1, and on a pair of imaginary straight lines IL2 and imaginary straight line IL3 that are symmetric with respect to the imaginary straight line IL1.

これにより、挿通孔１１ｃの中心とねじ止め部１１ｄの中心を結ぶ仮想直線ＩＬ１上と、仮想直線ＩＬ１を対称軸として線対称となる一対の仮想直線ＩＬ２上と仮想直線ＩＬ３上とにそれぞれリブ１１ｅを形成した。射出成形にて合成樹脂材をリブ状に形成した部分は、突出している方向に凸になる方向へ反りやすい傾向がある。   Thus, the ribs 11e are respectively provided on the virtual straight line IL1 connecting the center of the insertion hole 11c and the center of the screwing portion 11d, and on the pair of virtual straight lines IL2 and IL3 that are symmetric with respect to the virtual straight line IL1. Formed. A portion in which a synthetic resin material is formed in a rib shape by injection molding tends to warp in a protruding direction in a protruding direction.

したがって、仮想直線ＩＬ１、仮想直線ＩＬ２および仮想直線ＩＬ３に沿ってリブ１１ｅを設けることで、当接面１１ａ前面がケース１１の外方に凸になる方向へ反りやすくなり、元々当接面１１ｅが持つ、ケース１１の内側方向に凸になる方向に反りやすい、という傾向を相殺することができるため、小型・低背化しても当接面１１ａの反りが抑えられた電子部品用樹脂ケースを提供することができる、という効果を奏する。   Therefore, by providing the rib 11e along the virtual straight line IL1, the virtual straight line IL2, and the virtual straight line IL3, the front surface of the contact surface 11a is likely to be warped in a direction protruding outward from the case 11, and the contact surface 11e is originally formed from the contact surface 11e. The resin case for electronic parts in which the warpage of the contact surface 11a can be suppressed even if it is reduced in size and height can be compensated because the tendency to warp in the direction that protrudes toward the inside of the case 11 can be offset. There is an effect that can be done.

また、本実施形態の電子部品用樹脂ケース１１では、当接面１１ａ内に挿通孔１１ｃが設けられている。   Moreover, in the resin case 11 for electronic components of this embodiment, the insertion hole 11c is provided in the contact surface 11a.

前述の通り、箱状に形成された合成樹脂材でできた成形部品は内部方向に凸になるように反りやすい傾向があるが、一般的に貫通孔が設けられると反りは小さくなる傾向がある。したがって、当接面１１ａ内に挿通孔１１ｃを設けることで、当接面１１ａの反りを緩和することができる、という効果を奏する。   As described above, a molded part made of a synthetic resin material formed in a box shape tends to warp so as to be convex in the inner direction, but generally, when a through hole is provided, the warpage tends to be small. . Therefore, by providing the insertion hole 11c in the contact surface 11a, there is an effect that warpage of the contact surface 11a can be reduced.

また、本実施形態の電子部品用樹脂ケース１１では、挿通孔１１ｃの中心とねじ止め部１１ｄの中心を結ぶ仮想直線上ＩＬ１を対称軸として線対称となる一対の仮想直線ＩＬ２と仮想直線ＩＬ３は、挿通孔１１ｃの円周とねじ止め部１１ｄの円周との両方に接する直線とした。   Moreover, in the resin case 11 for electronic parts of this embodiment, a pair of virtual straight line IL2 and virtual straight line IL3 which are line-symmetrical about the virtual straight line IL1 connecting the center of the insertion hole 11c and the center of the screwing portion 11d are The straight line is in contact with both the circumference of the insertion hole 11c and the circumference of the screwing portion 11d.

これにより、最小限の本数のリブ１１ｅで効率的に当接面１１ａの反りが抑えられた電子部品用樹脂ケースを提供することができる、という効果を奏する。   Thereby, there is an effect that it is possible to provide a resin case for electronic parts in which the warpage of the contact surface 11a is efficiently suppressed with the minimum number of ribs 11e.

［第２実施形態］
以下に第１実施形態の電子部品用樹脂ケースであるケース１１を用いたセンサ装置１について図２、図３および図４を用いて説明する。図３はセンサ装置１の外観を示す図であり、図４はセンサ装置１が検知対象である被検知体ＴＶに取り付けられた状態を示す図である。 [Second Embodiment]
Hereinafter, a sensor device 1 using a case 11 that is a resin case for an electronic component according to a first embodiment will be described with reference to FIGS. 2, 3, and 4. FIG. 3 is a diagram illustrating an appearance of the sensor device 1, and FIG. 4 is a diagram illustrating a state in which the sensor device 1 is attached to a detection target TV that is a detection target.

センサ装置１は、図３および図４に示すように、ケース１１の挿通孔１１ｃに検知対象の動作を検知するセンサユニット１２が配置されたものである。なお、ケース１１についての説明は実施形態１でされている為、本実施形態の説明においては割愛するとともに、各箇所の符号については第１実施形態と同じ符号を用いて説明する。   As shown in FIGS. 3 and 4, the sensor device 1 includes a sensor unit 12 that detects an operation of a detection target in an insertion hole 11 c of the case 11. Since the description of the case 11 is made in the first embodiment, it will be omitted in the description of the present embodiment, and the same reference numerals as those in the first embodiment will be used for the reference numerals of the respective portions.

ケース１１は、図２に示すように、当接面１１ａに挿通孔１１ｃの中心とねじ止め部１１ｄの中心を結ぶ仮想直線ＩＬ１上と、仮想直線ＩＬ１を対称軸として線対称となる一対の仮想直線ＩＬ２および仮想直線ＩＬ３とに沿ってそれぞれリブ１１ｅを形成されている。   As shown in FIG. 2, the case 11 has a pair of virtual lines that are symmetric with respect to a virtual straight line IL1 that connects the center of the insertion hole 11c and the center of the screwing portion 11d to the contact surface 11a, and the virtual straight line IL1 as an axis of symmetry. Ribs 11e are formed along the straight line IL2 and the virtual straight line IL3, respectively.

なお、仮想直線ＩＬ３と仮想直線ＩＬ３とは、挿通孔１１ｃの円周とねじ止め部１１ｄの円周との両方に接する直線である。   The virtual straight line IL3 and the virtual straight line IL3 are straight lines that are in contact with both the circumference of the insertion hole 11c and the circumference of the screwing portion 11d.

センサユニット１２は、図４に示すように、検知対象である被検知体ＴＶの動作部ＭＰに係合し動作部ＭＰの動きに連動して回動可能に配置されたセンサ軸部１２ａを有し、センサ軸部１２ａの回転角度に比例して出力電圧を可変可能な位置検出センサである。   As shown in FIG. 4, the sensor unit 12 includes a sensor shaft portion 12 a that is engaged with the operation portion MP of the detection target TV that is a detection target and is rotatably arranged in conjunction with the movement of the operation portion MP. The position detection sensor can vary the output voltage in proportion to the rotation angle of the sensor shaft portion 12a.

センサユニット１２はセンサ軸部１２ａが当接面１１ａ側に露出するように貫通孔１１ｃの内部に係止され、センサ装置１となる。   The sensor unit 12 is locked inside the through hole 11 c so that the sensor shaft portion 12 a is exposed to the contact surface 11 a side, and becomes the sensor device 1.

次にセンサ装置１の動作について図３を用いて説明する。図３はセンサ装置１の取り付け状態を示す模式図である。   Next, operation | movement of the sensor apparatus 1 is demonstrated using FIG. FIG. 3 is a schematic view showing a mounting state of the sensor device 1.

センサ装置１は、図３に示すように、動作部ＭＰをセンサ軸部１２ａに係止して被検知体ＴＶに固定される。このとき、センサ装置１が保持される被検知体ＴＶの所定の面と当接面１１ａとは気密に保持された状態である。   As shown in FIG. 3, the sensor device 1 is fixed to the detection target TV by engaging the operation unit MP with the sensor shaft 12 a. At this time, the predetermined surface of the detection target TV on which the sensor device 1 is held and the contact surface 11a are in an airtight state.

したがって、動作部ＭＰが回転すると、動作部ＭＰを係止しているセンサ軸部１２ａが動作部ＭＰの回転動作に連動して回転し、センサ装置１はセンサ軸部１２ａの回転角度にあった出力電圧を出力する。これにより、出力電圧を見ることで、例えば、動作部ＭＰがスロットルバルブの回転軸であれば、スロットルバルブの開閉角度を検出することが可能となる。   Therefore, when the operation part MP rotates, the sensor shaft part 12a that locks the operation part MP rotates in conjunction with the rotation operation of the operation part MP, and the sensor device 1 is at the rotation angle of the sensor shaft part 12a. Output the output voltage. Thus, by looking at the output voltage, for example, if the operating unit MP is the rotary shaft of the throttle valve, it is possible to detect the opening / closing angle of the throttle valve.

上記にて例示したように、本実施形態のセンサ装置１は各種バルブの開閉角度検出に用いられることがある。仮に、各種バルブ内を流れる流体が被検知体ＴＶの所定の面と当接面１１ａとの間から漏れた場合、センサ装置１が検出した回転角度から算出した流体の流量と、実際にバルブ内を流れる流体の流量に大きな誤差が生じ、正しい制御ができなくなる。   As exemplified above, the sensor device 1 of the present embodiment may be used for detecting the opening / closing angles of various valves. If the fluid flowing in the various valves leaks from between the predetermined surface of the detection target TV and the contact surface 11a, the flow rate of the fluid calculated from the rotation angle detected by the sensor device 1 and the actual inside of the valve A large error occurs in the flow rate of the fluid flowing through the flow, and correct control cannot be performed.

したがって、センサ装置１が保持される被検知体ＴＶの所定の面と当接面１１ａとの気密性を保持し、流体の漏れを確実に防ぐ必要がある。   Therefore, it is necessary to maintain the airtightness between the predetermined surface of the detection target TV on which the sensor device 1 is held and the contact surface 11a, and to reliably prevent fluid leakage.

以下、本実施形態としたことによる効果について説明する。   Hereinafter, the effect by having set it as this embodiment is demonstrated.

本実施形態のセンサ装置１では、被検知体ＴＶの所定の面とセンサ装置１の当接面１１ａとが気密に保持された状態で被検知体ＴＶに固定されるセンサ装置において、センサ装置１の外形を形成するケース１１は、動作部ＭＰの移動または回転を検知可能なセンサユニット１２を挿通可能な挿通孔１１ｃと取り付け用のねじ止め部１１ｄとを備え、所定の面と当接する当接面１１ａを底面とし、ねじ止め部１１ｄは挿通孔１１ｃの中心点に対して点対称の位置に一対設け、前記底面において、挿通孔１１ｃの中心とねじ止め部１１ｄの中心を結ぶ仮想直線ＩＬ１上と、仮想直線ＩＬ１を対称軸として線対称となる一対の他の仮想直線ＩＬ２上と仮想直線ＩＬ３上とにそれぞれリブ１１ｅを形成した構造とした。   In the sensor device 1 of the present embodiment, the sensor device 1 is a sensor device that is fixed to the detected object TV in a state where the predetermined surface of the detected object TV and the contact surface 11a of the sensor device 1 are airtightly held. The case 11 that forms the outer shape of the case is provided with an insertion hole 11c through which the sensor unit 12 capable of detecting the movement or rotation of the operating portion MP can be inserted, and a screwing portion 11d for attachment, and is in contact with a predetermined surface. The surface 11a is a bottom surface, and a pair of screwing portions 11d are provided at point-symmetrical positions with respect to the center point of the insertion hole 11c. On the bottom surface, on the virtual straight line IL1 connecting the center of the insertion hole 11c and the center of the screwing portion 11d. The rib 11e is formed on each of a pair of other virtual straight lines IL2 and imaginary straight lines IL3 that are symmetric with respect to the virtual straight line IL1.

これにより、挿通孔１１ｃの中心とねじ止め部１１ｄの中心を結ぶ仮想直線ＩＬ１上と、仮想直線ＩＬ１を対称軸として線対称となる一対の仮想直線ＩＬ２上と仮想直線ＩＬ３上とにそれぞれリブ１１ｅを形成した。射出成形にて合成樹脂材をリブ状に形成した部分は、突出している方向に凸になる方向へ反りやすい傾向がある。   Thus, the ribs 11e are respectively provided on the virtual straight line IL1 connecting the center of the insertion hole 11c and the center of the screwing portion 11d, and on the pair of virtual straight lines IL2 and IL3 that are symmetric with respect to the virtual straight line IL1. Formed. A portion in which a synthetic resin material is formed in a rib shape by injection molding tends to warp in a protruding direction in a protruding direction.

したがって、仮想直線ＩＬ１、仮想直線ＩＬ２および仮想直線ＩＬ３に沿ってリブ１１ｅを設けることで、当接面１１ａ前面がケース１１の外方に凸になる方向へ反りやすくなり、元々当接面１１ｅが持つ、ケース１１の内側方向に凸になる方向に反りやすい、という傾向を相殺することができるため、小型・低背化しても当接面１１ａの反りが抑えられているため、被検知体ＴＶとセンサ装置１との当接箇所に隙間ができにくくなり、被検知体ＴＶとセンサ装置１との当接箇所の気密性を保持した状態で固定できるセンサ装置を提供することができる、という効果を奏する。   Therefore, by providing the rib 11e along the virtual straight line IL1, the virtual straight line IL2, and the virtual straight line IL3, the front surface of the contact surface 11a is likely to be warped in a direction protruding outward from the case 11, and the contact surface 11e is originally formed from the contact surface 11e. Since the tendency to warp in a direction that protrudes toward the inner side of the case 11 can be offset, the warping of the contact surface 11a is suppressed even if the size and height are reduced, so that the object TV is detected. The sensor device can be fixed in a state where the contact portion between the sensor device 1 and the sensor device 1 is less likely to have a gap and the airtightness of the contact portion between the detected object TV and the sensor device 1 is maintained. Play.

また、本実施形態のセンサ装置１では、仮想直線ＩＬ２と仮想直線ＩＬ３とは、挿通孔１１ｃの円周とねじ止め部１１ｄの円周との両方に接する直線である、とした。   In the sensor device 1 of the present embodiment, the virtual straight line IL2 and the virtual straight line IL3 are straight lines that are in contact with both the circumference of the insertion hole 11c and the circumference of the screwing portion 11d.

これにより、最小限の本数のリブ１１ｅで当接面１１ａの反りを効率的に抑えることで、被検知体ＴＶとセンサ装置１との当接箇所に隙間ができにくくなり、被検知体ＴＶとセンサ装置１との当接箇所の気密性を保持した状態で固定できるセンサ装置を提供することができる、という効果を奏する。   As a result, by efficiently suppressing the warp of the contact surface 11a with the minimum number of ribs 11e, it becomes difficult to form a gap at the contact portion between the detected object TV and the sensor device 1, and the detected object TV and There is an effect that it is possible to provide a sensor device that can be fixed in a state where the airtightness of the contact portion with the sensor device 1 is maintained.
