請求項４に記載の車両用視認装置は、請求項１〜請求項３の何れか１項に記載の車両用視認装置において、前記接触部の突出先端部の表面を前記接触部の突出方向側へ凸状に湾曲させる。 The visual recognition device for a vehicle according to claim 4 is the visual identification device for a vehicle according to any one of claims 1 to 3 , wherein a surface of a protruding tip end portion of the contact portion is located on a protruding direction side of the contact portion. Bend in a convex shape.
請求項１に記載の車両用視認装置では、車体に突出体が回動可能に支持されると共に、突出体に視認手段が設けられており、視認手段が車両の乗員の視認を補助する。また、車体の車幅方向外側端が配置される車幅方向に垂直な外垂直面からの突出体の車幅方向外方への突出寸法が８７．５ｍｍ以下にされている。 In the vehicle visual recognition device according to the first aspect, the projecting body is rotatably supported on the vehicle body, and the projecting body is provided with the visual recognition means. The visual recognition means assists the visual recognition of an occupant of the vehicle. Further, the protruding dimension of the protruding body outward in the vehicle width direction from the outer vertical surface perpendicular to the vehicle width direction in which the vehicle width direction outer end of the vehicle body is arranged is set to 87.5 mm or less.
ここで、突出体の車両後側端と回動中心軸線とが配置される配置垂直面の車幅方向に対する角度が４５°未満にされている。 Here, the angle with respect to the vehicle width direction of the arrangement vertical surface on which the vehicle rear side end of the protrusion and the rotation center axis are arranged is less than 45 °.
このため、外垂直面に車幅方向外側において接する上下方向に垂直な径１７５ｍｍの接触円（子供の頭部の断面と想定するもの）が突出体の車両後側端と接触した状態で車体に対し外垂直面に沿って車両前側に移動される際に、接触円が突出体を車体側に押圧して突出体の接触円による回動が困難になることを抑制でき、接触円が突出体を容易に回動させることができる。これにより、接触円が想定する子供の頭部に突出体から作用される衝撃を効果的に低減でき、子供を効果的に保護できる。 For this reason, the contact circle (which is assumed to be the cross section of the child's head) perpendicular to the vertical direction that is in contact with the outer vertical surface on the outer side in the vehicle width direction and is in contact with the vehicle rear end of the projecting body is attached to the vehicle body. On the other hand, when the contact circle moves toward the vehicle front along the outer vertical surface, it is possible to prevent the contact circle from pressing the protrusion toward the vehicle body and making it difficult for the protrusion to rotate due to the contact circle. Can be easily rotated. As a result, the impact of the projected circle on the child's head, which is assumed by the contact circle, can be effectively reduced, and the child can be effectively protected.
請求項１に記載の車両用視認装置では、突出体の車両後側端部に接触部が設けられており、接触部は車両後側に突出されている。このため、接触円が突出体に接触部において接触する確率を高くでき、接触円が突出体の車両後側端と接触できる確率を高くできる。 In the vehicle visual recognition device according to the first aspect, the contact portion is provided at the vehicle rear end of the projecting body, and the contact portion projects toward the vehicle rear side. Therefore, it is possible to increase the probability that the contact circle contacts the protrusion at the contact portion, and increase the probability that the contact circle contacts the vehicle rear end of the protrusion.
請求項２に記載の車両用視認装置では、接触部が視認手段に比し車両後側に突出されている。このため、子供の頭部が視認手段より前に接触部と接触することで、視認手段が破損することを抑制できる。 In the vehicle visual recognition device according to the second aspect, the contact portion projects toward the vehicle rear side as compared with the visual recognition means. Therefore, it is possible to prevent the visual recognition means from being damaged by the head of the child coming into contact with the contact portion before the visual recognition means.
請求項３に記載の車両用視認装置では、車体に突出体が回動可能に支持されると共に、突出体に視認手段が設けられており、視認手段が車両の乗員の視認を補助する。また、車体の車幅方向外側端が配置される車幅方向に垂直な外垂直面からの突出体の車幅方向外方への突出寸法が８７．５ｍｍ以下にされている。 In the vehicle visual recognition device according to the third aspect , the projecting body is rotatably supported on the vehicle body, and the projecting body is provided with the visual recognition means, and the visual recognition means assists the visual recognition of an occupant of the vehicle. Further, the protruding dimension of the protruding body outward in the vehicle width direction from the outer vertical surface perpendicular to the vehicle width direction in which the vehicle width direction outer end of the vehicle body is arranged is set to 87.5 mm or less.
ここで、突出体の車両前側端と回動中心軸線とが配置される配置垂直面の車幅方向に対する角度が４５°未満にされている。 Here, the angle with respect to the vehicle width direction of the arrangement vertical plane on which the vehicle front end of the projecting body and the rotation center axis are arranged is less than 45 °.
このため、外垂直面に車幅方向外側において接する上下方向に垂直な径１７５ｍｍの接触円（子供の頭部の断面と想定するもの）が突出体の車両前側端と接触した状態で車体に対し外垂直面に沿って車両後側に移動される際に、接触円が突出体を車体側に押圧して突出体の接触円による回動が困難になることを抑制でき、接触円が突出体を容易に回動させることができる。これにより、接触円が想定する子供の頭部に突出体から作用される衝撃を効果的に低減でき、子供を効果的に保護できる。 For this reason, a contact circle having a diameter of 175 mm (which is assumed to be the cross section of the child's head) perpendicular to the vertical direction that is in contact with the outer vertical surface on the outer side in the vehicle width direction with respect to the vehicle body in a state of being in contact with the vehicle front end of the projecting body. When the contact circle moves to the vehicle rear side along the outer vertical surface, it is possible to prevent the contact circle from pressing the protrusion body toward the vehicle body and making it difficult for the contact circle to rotate due to the contact circle. Can be easily rotated. As a result, the impact of the projected circle on the child's head, which is assumed by the contact circle, can be effectively reduced, and the child can be effectively protected.
請求項３に記載の車両用視認装置では、突出体の車両前側端部に接触部が設けられており、接触部は車両前側に突出されている。このため、接触円が突出体に接触部において接触する確率を高くでき、接触円が突出体の車両前側端と接触できる確率を高くできる。 In the vehicle visual recognition device according to the third aspect , the contact portion is provided at the vehicle front end of the projecting body, and the contact portion projects toward the vehicle front side. Therefore, it is possible to increase the probability that the contact circle contacts the protrusion at the contact portion, and increase the probability that the contact circle can contact the vehicle front end of the protrusion.
請求項４に記載の車両用視認装置では、接触部の突出先端部の表面が接触部の突出方向側へ凸状に湾曲されている。このため、子供の頭部に接触部の突出先端部から作用される衝撃を効果的に低減でき、子供を一層効果的に保護できる。 In the vehicle visual recognition device according to the fourth aspect , the surface of the protruding tip end portion of the contact portion is curved in a convex shape toward the protruding direction side of the contact portion. Therefore, it is possible to effectively reduce the impact applied to the child's head from the protruding tip of the contact portion, and to protect the child more effectively.
なお、本発明の車両用視認装置は、車両の乗員の視認を補助する視認手段と、車体に支持されると共に、前記視認手段が設けられ、車体に対し車幅方向外側かつ車両前側に突出される突出体と、を備えてもよい。 The visual recognition device for a vehicle of the present invention is provided with the visual recognition means for assisting visual recognition of an occupant of the vehicle and the visual recognition means, and the visual recognition means is provided so as to project to the vehicle width direction outer side and the vehicle front side with respect to the vehicle body.

The visual recognition means assists the visual recognition of an occupant of the vehicle.
ここで、突出体が車体に対し車幅方向外側かつ車両前側に突出されている。このため、突出体が車体に対し車幅方向外側かつ車両後側に突出される場合と異なり、突出体の車体に対する突出方向を乗員の視線方向と平行に近づけることができて、乗員の視界が突出体によって減少されることを抑制できる。しかも、乗員の視界において車体のピラー（特にフロントピラー）に突出体が重複される場合には、乗員の視界が突出体によって減少されることを一層抑制できる。 Here, the projecting body projects toward the vehicle front in the vehicle width direction outside with respect to the vehicle body. For this reason, unlike the case where the projecting body is projected outward in the vehicle width direction and rearward of the vehicle with respect to the vehicle body, the projecting direction of the projecting body with respect to the vehicle body can be made close to parallel to the line-of-sight direction of the occupant, and the visual field of the occupant is reduced. It is possible to suppress reduction by the protrusion. Moreover, when the projecting body is overlapped with the pillars (particularly the front pillars) of the vehicle body in the field of view of the occupant, it is possible to further prevent the field of view of the occupant from being reduced by the projecting body.

また、上記ハウジング２２は、乗員の目位置に対し車幅方向にずれた位置における車両前側かつ下側に配置される。 The housing 22 is arranged on the front side and the lower side of the vehicle at a position displaced in the vehicle width direction with respect to the eye position of the occupant.
次に、本実施形態の作用を説明する。 Next, the operation of this embodiment will be described.
以上の構成の撮像装置１０では、車両１２の走行面に対するハウジング２２の上下方向中央の高さ（略１ｍ）が、車両１２の走行面上に起立した子供（特に６歳以上８歳以下）の頭部（特に目の位置）の平均的な高さであり、ハウジング２２と子供の頭部とが接触することが想定される。さらに、子供（特に６歳以上８歳以下）の頭部（特に目の位置）の上下方向に垂直な断面の平均的な前後方向寸法（最大前後方向寸法）は、略１７５ｍｍであり、例えば法規（ＵＮ／ＥＣＥのＲ４６）で定められているインパクタの球状の頭部の中心が配置される上下方向に垂直な断面である径１７５ｍｍの接触円２６は、子供の頭部の上下方向に垂直な断面であると想定できる。 In the image pickup apparatus 10 having the above-described configuration, the height (approximately 1 m) of the vertical center of the housing 22 with respect to the traveling surface of the vehicle 12 is the height of a child (especially 6 to 8 years old) standing upright on the traveling surface of the vehicle 12. It is the average height of the head (particularly the eye position), and it is assumed that the housing 22 and the child's head are in contact with each other. Furthermore, the average longitudinal dimension (maximum longitudinal dimension) of the vertical section of the head (especially the position of eyes) of a child (especially 6 to 8 years old) is about 175 mm. The contact circle 26 having a diameter of 175 mm, which is a cross section perpendicular to the vertical direction in which the center of the spherical head of the impactor defined in (UN / ECE R46) is arranged, is perpendicular to the vertical direction of the child's head. It can be assumed to be a cross section.
本実施形態では、外垂直面Ｓに対するハウジング２２の車幅方向外方への突出寸法Ｔが８７．５ｍｍ以下にされており、接触円２６が外垂直面Ｓに車幅方向外側において接する状態でハウジング２２の車両後側から車体１４に対し車両前方に相対移動されて、接触円２６とハウジング２２の車両後側端とが接触を開始することが想定される。 In the present embodiment, the outward protruding dimension T of the housing 22 with respect to the outer vertical surface S is set to 87.5 mm or less, and the contact circle 26 contacts the outer vertical surface S on the outer side in the vehicle width direction. It is assumed that the contact circle 26 and the vehicle rear end of the housing 22 start contact with each other by being relatively moved from the vehicle rear side of the housing 22 to the vehicle front side with respect to the vehicle body 14.
ここで、ハウジング２２の車両後側端（接触円２６と接触を開始する接触開始位置Ｐ）と回動中心軸線Ｏとが配置される配置垂直面Ｕの車幅方向に対する角度θが４５°未満にされている。 Here, the angle θ with respect to the vehicle width direction of the arrangement vertical plane U on which the vehicle rear end of the housing 22 (the contact start position P that starts contact with the contact circle 26) and the rotation center axis O are arranged is less than 45 °. Has been
このため、配置垂直面Ｕの車幅方向に対する角度θが４５°以上にされる場合とは異なり、接触円２６がハウジング２２と接触した状態で車体１４に対し車両前方に相対移動される際に、接触円２６がハウジング２２を車体１４側に押圧してハウジング２２の接触円２６による車両前側への回動が困難になることを抑制でき、接触円２６がハウジング２２を容易に車両前側に回動させることができる。これにより、接触円２６が想定する子供の頭部にハウジング２２から作用される衝撃を効果的に低減でき、子供を効果的に保護できる。 Therefore, unlike the case where the angle θ of the arrangement vertical plane U with respect to the vehicle width direction is set to 45 ° or more, when the contact circle 26 is moved relative to the vehicle body 14 relative to the vehicle body 14 while being in contact with the housing 22. It is possible to prevent the contact circle 26 from pressing the housing 22 toward the vehicle body 14 side and making it difficult for the contact circle 26 of the housing 22 to rotate to the vehicle front side, and the contact circle 26 easily rotates the housing 22 to the vehicle front side. Can be moved. As a result, it is possible to effectively reduce the impact of the contact circle 26 acting on the head of the child from the housing 22 and to protect the child effectively.
さらに、ハウジング２２の車両後側端部に接触部２２Ａが設けられており、接触部２２Ａが車両後側に突出されている。このため、接触円２６がハウジング２２に車両後側から接触部２２Ａにおいて接触を開始する確率を高くでき、接触円２６がハウジング２２の車両後側端と接触を開始できる確率を高くできて、接触円２６が想定する子供の頭部にハウジング２２から作用される衝撃を効果的に低減できる確率を高くできる。 Further, a contact portion 22A is provided at the vehicle rear side end portion of the housing 22, and the contact portion 22A is projected to the vehicle rear side. Therefore, it is possible to increase the probability that the contact circle 26 starts contacting the housing 22 from the vehicle rear side at the contact portion 22A, and increase the probability that the contact circle 26 can start contacting the vehicle rear side end of the housing 22. It is possible to increase the probability that the impact applied from the housing 22 to the head of the child envisioned by the circle 26 can be effectively reduced.
しかも、接触部２２Ａの突出先端側部分の表面が車両後側へ凸状に湾曲されている。このため、子供の頭部に接触部２２Ａの突出先端側部分から作用される衝撃を効果的に低減でき、子供を一層効果的に保護できる。 Moreover, the surface of the protruding tip side portion of the contact portion 22A is curved in a convex shape toward the vehicle rear side. Therefore, the impact applied to the child's head from the protruding tip side portion of the contact portion 22A can be effectively reduced, and the child can be protected more effectively.
また、接触部２２Ａがカメラモジュール２４のレンズ２４Ａに比し車両後側に突出されている。このため、子供の頭部がレンズ２４Ａより前に接触部２２Ａと接触することで、カメラモジュール２４が破損することを抑制できる。 Further, the contact portion 22A is projected rearward of the vehicle as compared with the lens 24A of the camera module 24. Therefore, it is possible to prevent the camera module 24 from being damaged by the head of the child coming into contact with the contact portion 22A before the lens 24A.

FIG. 4 is a plan view of a main part of a vehicle 12 provided with an imaging device 30 as a vehicle visual recognition device according to a second embodiment of the present invention, as viewed from above.
本実施形態における車両１２（撮像装置３０を含む）は、上記第１実施形態と、ほぼ同様の構成であるが、以下の点で異なる。 The vehicle 12 (including the imaging device 30) in the present embodiment has substantially the same configuration as that of the first embodiment, but differs in the following points.
図４に示す如く、本実施形態に係る撮像装置３０では、ハウジング２２が車体１４に対し車幅方向外方へ向かうに従い車両前方へ向かう方向に突出されている。このため、ハウジング２２の車両前側面の車両前側端と車両後側端とが配置される鉛直面、ハウジング２２の車両後側面の車両前側端と車両後側端とが配置される鉛直面、ハウジング２２の車幅方向内側端部の車両前後方向中央とハウジング２２の車幅方向外側端部の車両前後方向中央とが配置される鉛直面、ハウジング２２の回動中心軸線Ｏの車幅方向位置における車両前側端とハウジング２２の車幅方向外側端部の車両前側端とが配置される鉛直面、ハウジング２２の回動中心軸線Ｏの車幅方向位置における車両後側端とハウジング２２の車幅方向外側端部の車両後側端とが配置される鉛直面、ハウジング２２の回動中心軸線Ｏとハウジング２２の車幅方向外側端部の車両前後方向中央とが配置される鉛直面、ハウジング２２の回動中心軸線Ｏとハウジング２２の車幅方向外側端部の車両前側端とが配置される鉛直面、及び、ハウジング２２の回動中心軸線Ｏとハウジング２２の車幅方向外側端部の車両後側端とが配置される鉛直面の少なくとも１つが、車幅方向外方へ向かうに従い車両前方へ向かう方向に傾斜されている。 As shown in FIG. 4, in the imaging device 30 according to the present embodiment, the housing 22 is projected in the direction toward the front of the vehicle as it goes outward in the vehicle width direction with respect to the vehicle body 14. For this reason, a vertical plane in which the vehicle front side end and the vehicle rear side end of the vehicle front side surface of the housing 22 are arranged, a vertical plane in which the vehicle front side end and the vehicle rear side end of the vehicle rear side surface of the housing 22 are arranged, 22 is a vertical plane in which the vehicle front-rear center of the vehicle width direction inner end portion and the vehicle width direction outer end of the housing 22 are arranged in the vehicle width direction position of the rotation center axis O of the housing 22. A vertical plane in which a vehicle front end and a vehicle front end of an outer end portion of the housing 22 in the vehicle width direction are arranged, a vehicle rear end at a vehicle width direction position of a rotation center axis O of the housing 22, and a vehicle width direction of the housing 22. A vertical plane on which the vehicle rear side end of the outer end is arranged, a vertical plane on which the rotation center axis O of the housing 22 and the vehicle width direction outer end center of the housing 22 in the vehicle front-rear direction are arranged, Center of rotation A vertical plane in which the line O and the vehicle front end of the housing 22 in the vehicle width direction outer end are arranged, and the rotation center axis O of the housing 22 and the vehicle rear side end of the vehicle width direction outer end of the housing 22. At least one of the vertical planes in which is arranged is inclined in the direction toward the front of the vehicle as it extends outward in the vehicle width direction.
ハウジング２２の車両前側面の車幅方向外側端には、接触部２２Ａが一体に設けられており、接触部２２Ａは、ハウジング２２の車両前側面（ハウジング２２の車幅方向外側面の車幅方向内側かつ車両前側の面）に対し車両前側に突出されて、ハウジング２２の最も車両前側の車両前側端部に配置されている。接触部２２Ａは、上下方向に延伸されており、接触部２２Ａの突出先端側部分の表面は、接触部２２Ａの長手方向から見て車両前側へ凸状（断面円弧状）に湾曲されている。 A contact portion 22A is integrally provided at an outer end of the housing 22 on the vehicle front side in the vehicle width direction. The contact portion 22A is formed on the vehicle front side of the housing 22 (the vehicle width direction outer side surface of the housing 22 in the vehicle width direction). It is projected at the vehicle front side with respect to the inner side and the vehicle front side), and is arranged at the vehicle front side end portion of the housing 22 closest to the vehicle front side. The contact portion 22A extends in the vertical direction, and the surface of the protruding tip side portion of the contact portion 22A is curved in a convex shape (arc-shaped cross section) toward the vehicle front side when viewed from the longitudinal direction of the contact portion 22A.
本実施形態では、外垂直面Ｓに対するハウジング２２の車幅方向外方への突出寸法Ｔが８７．５ｍｍ以下にされており、接触円２６が外垂直面Ｓに車幅方向外側において接する状態でハウジング２２の車両前側から車体１４に対し車両後方に相対移動されて、接触円２６とハウジング２２の車両前側端とが接触を開始することが想定される。 In the present embodiment, the outward protruding dimension T of the housing 22 with respect to the outer vertical surface S is set to 87.5 mm or less, and the contact circle 26 contacts the outer vertical surface S on the outer side in the vehicle width direction. It is assumed that the front side of the housing 22 is moved relative to the vehicle body 14 toward the rear side of the vehicle so that the contact circle 26 and the front end of the housing 22 start contact with each other.
ここで、ハウジング２２の車両前側端（接触円２６と接触を開始する接触開始位置Ｐ）と回動中心軸線Ｏとが配置される配置垂直面Ｕの車幅方向に対する角度θが４５°未満にされている。 Here, the angle θ with respect to the vehicle width direction of the arrangement vertical plane U on which the vehicle front end (the contact start position P that starts contact with the contact circle 26) of the housing 22 and the rotation center axis O are arranged is less than 45 °. Has been done.
このため、配置垂直面Ｕの車幅方向に対する角度θが４５°以上にされる場合とは異なり、接触円２６がハウジング２２と接触した状態で車体１４に対し車両後方に相対移動される際に、接触円２６がハウジング２２を車体１４側に押圧してハウジング２２の接触円２６による車両後側への回動が困難になることを抑制でき、接触円２６がハウジング２２を容易に車両後側に回動させることができる。これにより、接触円２６が想定する子供の頭部にハウジング２２から作用される衝撃を効果的に低減でき、子供を効果的に保護できる。 Therefore, unlike when the angle θ of the arrangement vertical plane U with respect to the vehicle width direction is set to 45 ° or more, when the contact circle 26 is moved relative to the vehicle body 14 rearward with respect to the vehicle body 14 in a state of being in contact with the housing 22. It is possible to prevent the contact circle 26 from pressing the housing 22 toward the vehicle body 14 and making it difficult for the contact circle 26 of the housing 22 to rotate toward the vehicle rear side, and the contact circle 26 easily moves the housing 22 toward the vehicle rear side. Can be rotated. As a result, it is possible to effectively reduce the impact of the contact circle 26 acting on the head of the child from the housing 22 and to protect the child effectively.
さらに、ハウジング２２の車両前側端部に接触部２２Ａが設けられており、接触部２２Ａが車両前側に突出されている。このため、接触円２６がハウジング２２に車両前側から接触部２２Ａにおいて接触を開始する確率を高くでき、接触円２６がハウジング２２の車両前側端と接触を開始できる確率を高くできて、接触円２６が想定する子供の頭部にハウジング２２から作用される衝撃を効果的に低減できる確率を高くできる。 Further, a contact portion 22A is provided at a vehicle front end portion of the housing 22, and the contact portion 22A is projected to the vehicle front side. Therefore, it is possible to increase the probability that the contact circle 26 starts contacting the housing 22 from the vehicle front side at the contact portion 22A, and increase the probability that the contact circle 26 can start contacting the vehicle front side end of the housing 22. It is possible to increase the probability that the impact applied from the housing 22 to the child's head supposed to be effectively reduced can be effectively reduced.
しかも、接触部２２Ａの突出先端側部分の表面が車両前側へ凸状に湾曲されている。このため、子供の頭部に接触部２２Ａの突出先端側部分から作用される衝撃を効果的に低減でき、子供を一層効果的に保護できる。 Moreover, the surface of the protruding tip side portion of the contact portion 22A is curved in a convex shape toward the vehicle front side. Therefore, the impact applied to the child's head from the protruding tip side portion of the contact portion 22A can be effectively reduced, and the child can be protected more effectively.
また、ハウジング２２が車体１４に対し車幅方向外方へ向かうに従い車両前方へ向かう方向に突出されている。このため、ハウジング２２が車体１４に対し車幅方向外方へ向かうに従い車両後方へ向かう方向に突出される場合と異なり、ハウジング２２の車体１４に対する突出方向を乗員の視線方向と平行に近づけることができ、乗員の視界がハウジング２２によって減少されることを抑制できる。 Further, the housing 22 projects toward the front of the vehicle as it extends outward in the vehicle width direction with respect to the vehicle body 14. Therefore, unlike the case where the housing 22 projects toward the rear of the vehicle as it goes outward in the vehicle width direction with respect to the vehicle body 14, the projecting direction of the housing 22 with respect to the vehicle body 14 can be made close to parallel to the occupant's line-of-sight direction. Therefore, it is possible to prevent the visual field of the occupant from being reduced by the housing 22.
なお、本実施形態では、乗員の視界において車体１４のピラー１８にハウジング２２を重複させる配置にしてもよい。これにより、乗員の視界がハウジング２２によって減少されることを一層抑制できる。 In the present embodiment, the housing 22 may overlap the pillar 18 of the vehicle body 14 in the occupant's field of view. As a result, the visibility of the occupant can be further suppressed from being reduced by the housing 22.
さらに、上記第１実施形態及び第２実施形態では、ハウジング２２の回動中心軸線Ｏの車両前後方向位置における車体１４の車幅方向外側端が配置される車幅方向に垂直な面を外垂直面Ｓにした。しかしながら、ハウジング２２の回動中心軸線Ｏの車両前後方向近傍（例えばハウジング２２と接触を開始される接触円２６の車両前後方向範囲）における車体１４の車幅方向外側端が配置される車幅方向に垂直な面、又は、車体１４の車両前後方向全体のうちの車幅方向最外側端が配置される車幅方向に垂直な面を、外垂直面Ｓにしてもよい。 Furthermore, in the above-described first and second embodiments, the surface perpendicular to the vehicle width direction in which the vehicle width direction outer end of the vehicle body 14 at the vehicle front-rear direction position of the rotation center axis O of the housing 22 is arranged is the outer vertical direction. I made it to surface S. However, in the vehicle width direction in which the vehicle width direction outer end of the vehicle body 14 is arranged in the vicinity of the rotation center axis O of the housing 22 in the vehicle front-rear direction (for example, the vehicle front-rear direction range of the contact circle 26 that starts contact with the housing 22). The surface perpendicular to the vehicle vertical direction or the surface vertical to the vehicle width direction in which the outermost end in the vehicle width direction of the entire vehicle front-rear direction is arranged may be the outer vertical surface S.
また、上記第１実施形態及び第２実施形態では、ハウジング２２の車両後側面又は車両前側面の車幅方向外側端に接触部２２Ａを設けた。しかしながら、例えば図３に示す如く、ハウジング２２の車両後側面又は車両前側面の車幅方向外側端部の上部及び下部の少なくとも一方に接触部２２Ａを設けてもよい。 Further, in the first and second embodiments described above, the contact portion 22A is provided at the vehicle width direction outer end of the housing 22 on the vehicle rear side surface or the vehicle front side surface. However, as shown in FIG. 3, for example, the contact portion 22A may be provided on at least one of the upper side and the lower side of the vehicle width direction outer side end portion of the housing 22 on the vehicle rear side surface or the vehicle front side surface.
さらに、上記第１実施形態及び第２実施形態では、接触部２２Ａの表面を接触部２２Ａの長手方向から見て凸状に湾曲させた。しかしながら、接触部２２Ａの表面を接触部２２Ａの長手方向から見て凸状に屈曲させてもよい。 Furthermore, in the first and second embodiments described above, the surface of the contact portion 22A is curved in a convex shape when viewed from the longitudinal direction of the contact portion 22A. However, the surface of the contact portion 22A may be bent in a convex shape when viewed from the longitudinal direction of the contact portion 22A.
また、上記第１実施形態及び第２実施形態では、撮像装置１０、３０を車体１４のサイドドア１６に設置した。しかしながら、撮像装置１０、３０を車体１４のサイドドア１６以外の部分に設置してもよい。 In addition, in the first and second embodiments described above, the imaging devices 10 and 30 are installed on the side door 16 of the vehicle body 14. However, the imaging devices 10 and 30 may be installed in a portion of the vehicle body 14 other than the side door 16.
さらに、上記第１実施形態及び第２実施形態では、本発明の車両用視認装置を撮像装置１０、３０にした。しかしながら、本発明の車両用視認装置をミラー（光学ミラー）にして、ミラーが表示する像によって乗員の視認を補助してもよい。 Furthermore, in the first and second embodiments described above, the vehicle visual recognition device of the present invention is the imaging device 10 or 30. However, the vehicle visual recognition device of the present invention may be a mirror (optical mirror), and the visual confirmation of the occupant may be assisted by the image displayed by the mirror.
