　（作用）
　以上のように構成される本実施形態のドアミラー装置１０によれば以下の作用効果を奏する。 (Action)
According to the door mirror device 10 of the present embodiment configured as described above, the following operational effects are exhibited.
　本実施形態のドアミラー装置１０は、ミラー体４０を支持するベース２０の本体部２２にサイドドア１４の周囲を照射する発光部５０が備えられている。この発光部５０は本体部２２の外壁部３２Ａに設けられた設置部３４に設置されている。一方、外壁部３２Ａにおける設置部３４が設けられている面の裏面側には複数のリブ３６が形成されている。 The door mirror device 10 of the present embodiment is provided with a light emitting unit 50 that illuminates the periphery of the side door 14 on the main body 22 of the base 20 that supports the mirror body 40. The light emitting unit 50 is installed on the installation unit 34 provided on the outer wall 32A of the main body 22. On the other hand, a plurality of ribs 36 are formed on the back surface side of the surface of the outer wall portion 32A on which the installation portion 34 is provided.
　本実施形態では、ＬＥＤ５２の発光によりＬＥＤ５２や制御基板５４が発熱した場合、この熱は外壁部３２Ａを経由してリブ３６から放熱される。したがって、本実施形態のドアミラー装置１０によれば、発光時の熱によるＬＥＤ５２及び制御基板５４の故障が抑制される。ＬＥＤ照明は出力を上げることで発熱量が増加するが、本実施形態によれば、ＬＥＤ５２の出力を上げることができ、照度を上げることができる。 In the present embodiment, when the LED 52 and the control board 54 generate heat due to the light emission of the LED 52, this heat is radiated from the rib 36 via the outer wall portion 32A. Therefore, according to the door mirror device 10 of the present embodiment, failure of the LED 52 and the control board 54 due to heat at the time of light emission is suppressed. Although the amount of heat generated by the LED lighting increases by increasing the output, according to the present embodiment, the output of the LED 52 can be increased and the illuminance can be increased.
　また、本実施形態のドアミラー装置１０では、ダイカスト製の本体部２２に設けられたリブ３６は、金型の抜き方向（図２の矢印Ｎ方向）に沿って形成されている。このため、金型の分割数を増やすことなく本体部２２を製造することができる。これにより、本体部２２を含むドアミラー装置１０の製造工数を軽減でき、製造コストが抑制される。 In addition, in the door mirror device 10 of the present embodiment, the ribs 36 provided on the die-cast main body 22 are formed along the die removing direction (the arrow N direction in FIG. 2). Therefore, the main body portion 22 can be manufactured without increasing the number of divided molds. Thereby, the number of manufacturing steps of the door mirror device 10 including the main body 22 can be reduced, and the manufacturing cost can be suppressed.
　また、本実施形態のリブ３６は、ミラー体４０が張出す車幅方向外側に配置されている。したがって、本実施形態によれば、車幅方向外側に配置された複数のリブ３６が、車両下方側に倒れる方向（図１の矢印Ｆ）に働く荷重に対して、ベース２０を補強する機能を果たす。 Further, the rib 36 of the present embodiment is arranged outside the vehicle width direction where the mirror body 40 extends. Therefore, according to the present embodiment, the plurality of ribs 36 arranged on the outer side in the vehicle width direction have the function of reinforcing the base 20 against the load acting in the direction of falling to the vehicle lower side (arrow F in FIG. 1). Fulfill
　さらに、本実施形態のドアミラー装置１０では、格納機構及び鏡面調整機構に延びる配線４６が挿通される挿通孔３０Ａを囲むようにリブ３６が設けられている（図３参照）。そのため、本実施形態によれば、本体部２２において挿通孔３０Ａの周囲を補強することができる。 Further, in the door mirror device 10 of the present embodiment, the rib 36 is provided so as to surround the insertion hole 30A into which the wiring 46 extending to the storage mechanism and the mirror surface adjustment mechanism is inserted (see FIG. 3). Therefore, according to the present embodiment, the periphery of the insertion hole 30A in the main body portion 22 can be reinforced.
　以上、本実施形態のドアミラー装置１０によれば、発光部５０を配置したベース２０の本体部２２において、発光部５０と反対側にリブ３６を設けることで、発光部５０の放熱性能を向上させると共に、本体部２２の剛性を向上させることができる。 As described above, according to the door mirror device 10 of the present embodiment, in the main body portion 22 of the base 20 in which the light emitting portion 50 is arranged, the rib 36 is provided on the side opposite to the light emitting portion 50, thereby improving the heat dissipation performance of the light emitting portion 50. At the same time, the rigidity of the main body portion 22 can be improved.

　本実施形態では、発光部５０を覆うレンズがベースカバーと一体で形成されている。すなわち、本実施形態のベースカバー１２６は、発光部５０と対向する部分がレンズ１２８として形成されている。また、レンズ１２８は、意匠面Ｓの一部を形成する透過部１２８Ａと、透過部１２８Ａの周囲から外壁部３２Ａに向けて延びる角筒状のカバー部１２８Ｂが設けられている。このカバー部１２８Ｂの先端がシール材を介して外壁部３２Ａと接触することで、レンズ１２８の内部は気密が保持されている。 In this embodiment, the lens that covers the light emitting unit 50 is formed integrally with the base cover. That is, in the base cover 126 of this embodiment, the portion facing the light emitting unit 50 is formed as the lens 128. Further, the lens 128 is provided with a transmissive portion 128A forming a part of the design surface S and a rectangular tubular cover portion 128B extending from the periphery of the transmissive portion 128A toward the outer wall portion 32A. The inside of the lens 128 is kept airtight by the tip of the cover portion 128B coming into contact with the outer wall portion 32A via the sealing material.
　本実施形態のベースカバー１２６は、樹脂製であって、バイザ４４と同じ色、すなわち、サイドドア１４を含む車両１２のボデーと同じ色に配色されている。つまり、本実施形態のレンズ１２８はボデーと同じ色に配色されている。本実施形態のレンズ１２８は透明ではなく可視光を透過しないが、赤外光を透過可能に形成されている。 The base cover 126 of the present embodiment is made of resin and has the same color as the visor 44, that is, the same color as the body of the vehicle 12 including the side door 14. That is, the lens 128 of this embodiment is colored in the same color as the body. The lens 128 of the present embodiment is not transparent and does not transmit visible light, but is formed to be able to transmit infrared light.
　以上のように構成される本実施形態のドアミラー装置１００によれば、第１の実施形態の効果に加えて、次の効果を奏する。すなわち、本実施形態によれば、発光部５０の照射光を透過するレンズ１２８（透過部１２８Ａ）がベースカバー１２６と一体化されている。そのため、ベースカバー１２６の意匠性を向上させることができる。 According to the door mirror device 100 of the present embodiment configured as described above, in addition to the effects of the first embodiment, the following effects are exhibited. That is, according to the present embodiment, the lens 128 (transmissive portion 128A) that transmits the irradiation light of the light emitting unit 50 is integrated with the base cover 126. Therefore, the design of the base cover 126 can be improved.
　また、本実施形態によれば、赤外光を照射するＬＥＤ５２において、出力を上げることができ、照度を上げることができる。このため、ＬＥＤ５２を不透明のレンズ１２８で覆うことができる。 Further, according to this embodiment, the output can be increased and the illuminance can be increased in the LED 52 that irradiates infrared light. Therefore, the LED 52 can be covered with the opaque lens 128.
〔リブの配置の変形例〕
　上記の各実施形態では、挿通孔３０Ａに対して放射状となるように４本のリブ３６を配置したが、配置の方法についてはこの限りではない。以下に変形例を示す。 [Modification of rib arrangement]
In each of the above-described embodiments, the four ribs 36 are arranged radially with respect to the insertion hole 30A, but the arrangement method is not limited to this. A modified example is shown below.
　（変形例１）
　図５に示されるように、変形例１は外壁部３２Ａの内周面から挿通孔３０Ａ側に向けて略垂直に立設するように８本のリブ３６を配置した例である。詳しくは、外壁部３２Ａの車幅方向外側の内周面には、４本のリブ３６が底面視において平行となるように配置されている。また、外壁部３２Ａの車両前方側の内周面には、２本のリブ３６が底面視において平行となるように配置され、外壁部３２Ａの車両後方側の内周面には、２本のリブ３６が底面視において平行となるように配置されている。 (Modification 1)
As shown in FIG. 5, the first modification is an example in which eight ribs 36 are arranged so as to stand substantially vertically from the inner peripheral surface of the outer wall portion 32A toward the insertion hole 30A side. Specifically, four ribs 36 are arranged on the inner peripheral surface of the outer wall portion 32A on the outer side in the vehicle width direction so as to be parallel to each other in a bottom view. Further, two ribs 36 are arranged on the inner peripheral surface of the outer wall portion 32A on the vehicle front side so as to be parallel to each other in a bottom view, and two ribs 36 are formed on the inner peripheral surface of the outer wall portion 32A on the vehicle rear side. The ribs 36 are arranged so as to be parallel to each other in a bottom view.
　変形例１によれば、外壁部３２Ａにおいてリブ３６が立設する方向の強度を向上させることができる。 According to the first modification, the strength of the outer wall portion 32A in the direction in which the rib 36 stands can be improved.
　（変形例２）
　図６に示されるように、変形例２は外壁部３２Ａの車幅方向外側の内周面から挿通孔３０Ａ側に向けて略垂直に立設し、かつ長さが不均一の４本のリブ３６を配置した例である。補足すると、外壁部３２Ａの車幅方向外側の内周面には、４本のリブ３６が底面視において平行となるように配置されている。そして、車両前後方向外側の２本のリブ３６は、車両前後方向内側の２本のリブ３６よりも車幅方向の長さが短くなるように形成されている。つまり、設置部３４（詳しくは、ＬＥＤ５２）の中心から車両前後方向外側に離れるにつれて長さが短くなるように形成されている。 (Modification 2)
As shown in FIG. 6, in the second modification, four ribs are erected substantially vertically from the inner peripheral surface on the outer side in the vehicle width direction of the outer wall portion 32A toward the insertion hole 30A side and have an uneven length. This is an example in which 36 is arranged. Supplementally, four ribs 36 are arranged on the inner peripheral surface of the outer wall portion 32A on the outer side in the vehicle width direction so as to be parallel to each other in a bottom view. The two ribs 36 on the outer side in the vehicle front-rear direction are formed to have a shorter length in the vehicle width direction than the two ribs 36 on the inner side in the vehicle front-rear direction. That is, the length of the installation portion 34 (specifically, the LED 52) is formed so as to become shorter as the distance from the center of the installation portion 34 to the outside in the vehicle front-rear direction increases.
　変形例２によれば、外壁部３２Ａにおいてリブ３６が立設する方向の強度を向上させることができる他に次の効果を奏する。すなわち、ＬＥＤ５２の熱は光源の中心から離れるにつれて減少するため、ＬＥＤ５２の中心部からの距離に応じてリブ３６の長さを調整することにより、均一の長さのリブ３６を発光部５０の裏面に設けるよりも効率的に熱を放射することができる。さらには、ベース２０（本体部２２）の内部における空間の確保、及びベース２０の重量を低減することができる。 According to the second modification, the strength in the direction in which the ribs 36 are erected on the outer wall portion 32A can be improved, and the following effects are exhibited. That is, the heat of the LED 52 decreases as the distance from the center of the light source increases. Therefore, by adjusting the length of the rib 36 according to the distance from the center of the LED 52, the rib 36 having a uniform length can be formed on the back surface of the light emitting unit 50. The heat can be radiated more efficiently than that provided in the. Further, it is possible to secure a space inside the base 20 (main body portion 22) and reduce the weight of the base 20.
〔備考〕
　上記の各実施形態及び変形例２では、本体部２２に対して４本のリブ３６を、変形例１では８本のリブ３６をそれぞれ設けたが、リブ３６の数はこの限りではない。リブ３６の数は発光部５０の放熱性能や本体部２２の剛性を加味して設定することができる。また、各実施形態及び各変形例のリブ３６は断面が矩形状であるが、この限りではなく、金型の抜き方向に沿って形成されている限り、三角状の断面でも波型の断面であってもよい。また、各リブ３６は、基部である外壁部３２Ａの内周面から挿通孔３０Ａ側の先端部まで、一定の厚さでなくてもよい。 [Remarks]
Although the four ribs 36 are provided on the main body portion 22 and the eight ribs 36 are provided on the main body portion 22 in each of the above-described embodiments and the modified example 2, the number of the ribs 36 is not limited to this. The number of ribs 36 can be set in consideration of the heat dissipation performance of the light emitting unit 50 and the rigidity of the main body unit 22. Further, the rib 36 of each embodiment and each modification has a rectangular cross section, but the rib 36 is not limited to this and may have a triangular cross section or a corrugated cross section as long as the rib 36 is formed along the drawing direction of the mold. It may be. Further, each rib 36 does not have to have a constant thickness from the inner peripheral surface of the outer wall portion 32A, which is the base portion, to the distal end portion on the insertion hole 30A side.
　また、各実施形態及び各変形例において、各リブ３６の長さ、及び隣接するリブ３６同士の間隔は均一でなくてもよい。さらに、各リブ３６は、図５の変形例２に示されるように、設置部３４が設けられている面の裏面側以外に形成してもよい。 Further, in each embodiment and each modification, the length of each rib 36 and the interval between the adjacent ribs 36 may not be uniform. Further, each rib 36 may be formed on a surface other than the back surface side where the installation portion 34 is provided, as shown in the second modification of FIG.
　なお、各実施形態及び各変形例では、光源として１つのＬＥＤ５２（発光部５０）を設けたが、ＬＥＤ５２は複数設けてもよい。 In each embodiment and each modification, one LED 52 (light emitting unit 50) is provided as a light source, but a plurality of LEDs 52 may be provided.
　また、第２の実施形態のベースカバー１２６は、透過部１２８Ａのみを透明の樹脂により形成してもよい。また、ベースカバー１２６全体を無着色で透明の樹脂により形成し、透過部１２８Ａ以外の部分を着色してもよい。これらの場合、発光部５０は可視光を照射するＬＥＤ照明とすることができる。 Further, in the base cover 126 of the second embodiment, only the transparent portion 128A may be formed of transparent resin. Alternatively, the entire base cover 126 may be formed of a colorless transparent resin, and the portion other than the transmissive portion 128A may be colored. In these cases, the light emitting unit 50 can be an LED illumination that emits visible light.
　各実施形態は、本開示の車両用視認装置をドアミラー装置に対して適用したものである。しかしながら、本開示の車両用視認装置はカメラを備えた撮像装置にも適用することができる。この場合、発光部５０をカメラ用の照明として使用することができる。その他、本開示は他の車両用アウタミラー装置（例えば、フェンダミラー装置）に適用してもよい。
　２０１８年１１月１２日に出願された日本国特許出願２０１８－２１２５５８号の開示は、その全体が参照により本明細書に取込まれる。 Each embodiment applies the vehicle visual recognition device of the present disclosure to a door mirror device. However, the vehicle visual recognition device of the present disclosure can also be applied to an imaging device including a camera. In this case, the light emitting unit 50 can be used as illumination for the camera. In addition, the present disclosure may be applied to other vehicle outer mirror devices (for example, fender mirror devices).
