Description
本発明は車両用ルーフマウントアンテナ装置し、特に、車両ルーフに設置する際に車両ルーフに仮止めされる車両用ルーフマウントアンテナ装置に関する。 The present invention relates to a vehicle roof mount antenna device, and more particularly to a vehicle roof mount antenna device that is temporarily fixed to a vehicle roof when installed on the vehicle roof.
一般に、車両用ルーフマウントアンテナ装置は、その設置の際に、アンテナベースから車両ルーフ側に伸びた脚部の先端に設けられる仮止爪で車両ルーフに仮止めされた後に、車両室内側からねじ止めにより固定される。 In general, a roof mount antenna device for a vehicle is screwed from the vehicle interior side after being temporarily fixed to the vehicle roof by a temporary pawl provided at the tip of a leg extending from the antenna base to the vehicle roof side. It is fixed by a stop.
例えば、本願出願人と同一出願人による特許文献１には、アンテナベース側を支点に撓み可能に構成された複数の突出爪が設けられている仮止め構造が開示されている。特許文献１に開示の技術は、アンテナ装置を車両ルーフに設置の際に、車両ルーフの設置孔に突出爪を挿入し、突出爪がアンテナベース側を支点に、先端側が設置孔の内側に撓み、設置孔通過後に突出爪が元の形状に戻り、車両ルーフに係止されることでアンテナベースが仮止めされるものである。 For example, Patent Document 1 by the same applicant as the present applicant discloses a temporary fixing structure provided with a plurality of protruding claws configured to be able to bend with an antenna base side as a fulcrum. In the technique disclosed in Patent Document 1, when the antenna device is installed on the vehicle roof, a protruding claw is inserted into the installation hole of the vehicle roof, the protruding claw is bent on the antenna base side, and the tip side is bent inside the installation hole. The projecting claw returns to its original shape after passing through the installation hole, and the antenna base is temporarily fixed by being locked to the vehicle roof.
また、このような仮止爪により、車両ルーフにアンテナベースが仮止めされる車両用ルーフマウントアンテナ装置の他の例としては、例えば特許文献２がある。特許文献２には、アンテナベースから突出する筒状体に、アンテナベース側を支点に撓み可能に構成された係止爪が設けられている仮止め構造が開示されている。この例でも、アンテナ装置を車両ルーフに設置の際に、車両ルーフの設置孔に筒状体を挿入し、設置孔を貫通する際に係止爪がアンテナベース側を支点に、先端側が設置孔の内側に撓み、設置孔通過後に係止爪が元の形状に戻り、車両ルーフに係止されることでアンテナベースが仮止めされるものである。 Another example of the vehicle roof mount antenna device in which the antenna base is temporarily fixed to the vehicle roof by such temporary fixing claws is disclosed in Patent Document 2, for example. Patent Document 2 discloses a temporary fixing structure in which a latching claw configured to be able to bend with an antenna base side as a fulcrum is provided on a cylindrical body protruding from an antenna base. Also in this example, when the antenna device is installed on the vehicle roof, a cylindrical body is inserted into the installation hole of the vehicle roof, and when passing through the installation hole, the locking claw is the antenna base side as a fulcrum and the tip side is the installation hole. The locking claw returns to its original shape after passing through the installation hole, and the antenna base is temporarily fixed by being locked to the vehicle roof.
しかしながら、上述のような従来技術は、何れもアンテナベース側を支点に撓み可能に構成されているものである。このような構成の場合、係止部の長さ、即ち、アンテナベース側から延在し車両ルーフの設置孔を貫通して車両室内側に延びる先端部までの長さが、車両ルーフの厚み等に応じて長くなり、係止部の強度が弱くなるため仮止め時のアンテナベースのガタつきが大きくなる場合があった。また、車両ルーフの設置孔を貫通する際に、係止部が内側に撓んだまま曲がり癖が付いてしまい、固定力が低下し、ねじ止めを行う際にアンテナベースが脱落してしまう場合もあった。そして、このような変形が生じると、固定用のねじが接触してしまい、アンテナ装置の車両ルーフへの固定がスムーズに行かない場合もあった。さらに、アンテナ装置を一旦取り外した上で再度取り付ける必要が生じた場合、取り外す際に係止部が折れてしまう恐れもあった。また、車内の設置スペースが限られているため、アンテナベースから突出する仮止め部の長さを短くしたいという要望もあった。 However, all of the conventional techniques as described above are configured to be able to bend with the antenna base side as a fulcrum. In such a configuration, the length of the locking portion, that is, the length from the antenna base side to the front end portion extending through the installation hole of the vehicle roof and extending to the vehicle interior side is the thickness of the vehicle roof. In some cases, the length of the antenna base becomes unstable and the strength of the locking portion becomes weak, so that the backlash of the antenna base at the time of temporary fixing may increase. Also, when passing through the installation hole of the vehicle roof, when the locking part is bent inward, the bend crease is attached, the fixing force is reduced, and the antenna base falls off when screwing There was also. And when such a deformation | transformation arises, the screw for fixing will contact and the antenna apparatus may not be fixed to the vehicle roof smoothly. Furthermore, when the antenna device needs to be removed and then attached again, the locking portion may be broken when the antenna device is removed. Further, since the installation space in the vehicle is limited, there has been a demand for shortening the length of the temporary fixing portion protruding from the antenna base.
本発明は、斯かる実情に鑑み、車両ルーフに確実に仮固定され、仮止め部の設計自由度も高い車両用ルーフマウントアンテナ装置を提供しようとするものである。 In view of such circumstances, the present invention intends to provide a roof mount antenna device for a vehicle that is securely fixed to a vehicle roof and has a high degree of freedom in designing a temporary fixing portion.
上述した本発明の目的を達成するために、車両用ルーフマウントアンテナ装置は、板状のアンテナベースと、アンテナベースの車両ルーフ側の面から突出する管状脚部と、管状脚部の先端近傍からアンテナベース側に延在して設けられる仮止め部であって、管状脚部の先端近傍を支点に撓み可能に構成されると共に車両ルーフに設けられる設置孔に係止する係止爪を仮止め部の先端側に有し、管状脚部が設置孔を貫通する際に管状脚部内側方向に撓み、貫通後に元の位置に戻り設置孔に係止する仮止め部と、を具備するものである。 In order to achieve the above-described object of the present invention, a vehicle roof mount antenna device includes a plate-shaped antenna base, a tubular leg protruding from the surface of the antenna base on the vehicle roof side, and from the vicinity of the tip of the tubular leg. Temporary fixing part that extends to the antenna base side, and is configured to be able to bend around the end of the tubular leg part as a fulcrum, and to temporarily fix the locking claw that locks in the installation hole provided in the vehicle roof And a temporary fixing portion that is bent toward the inner side of the tubular leg when the tubular leg penetrates the installation hole, returns to the original position after the penetration, and is locked to the installation hole. is there.
さらに、車両室内から車両用ルーフマウントアンテナ装置にケーブルを接続するための、管状脚部が設置孔を貫通後に車両室内側から嵌合されるケーブル接続部を具備し、ケーブル接続部は、そのアンテナベース側の面から突出し管状脚部の内側に嵌合する管状突出部を有するものであっても良い。 Further, the tubular leg portion for connecting the cable from the vehicle interior to the vehicle roof mount antenna device includes a cable connection portion that is fitted from the vehicle interior side after passing through the installation hole, and the cable connection portion includes the antenna. It may have a tubular protrusion that protrudes from the surface on the base side and fits inside the tubular leg.
また、管状突出部は、管状脚部が設置孔を貫通後に、仮止め部が管状脚部内側方向に撓まないように、仮止め部を管状脚部内側から支えるものであっても良い。 Further, the tubular protruding portion may support the temporary fixing portion from the inner side of the tubular leg portion so that the temporary fixing portion does not bend in the inner direction of the tubular leg portion after the tubular leg portion penetrates the installation hole.
また、管状脚部の内周形状及び管状突出部の外周形状は、管状突出部を管状脚部に挿入する角度が所定方向に固定されるように、挿入方向を軸とする回転方向で回転制限を受ける形状であっても良い。 In addition, the inner peripheral shape of the tubular leg and the outer peripheral shape of the tubular protrusion are limited in rotation in the rotation direction about the insertion direction so that the angle at which the tubular protrusion is inserted into the tubular leg is fixed in a predetermined direction. The shape to receive may be sufficient.
また、管状突出部は、その外周先端が面カットされても良い。 Moreover, as for a tubular protrusion part, the outer periphery front-end | tip may be surface-cut.
そして、アンテナベースは、その車両ルーフ側の面から突出し、係止部を有する回転防止突出部を具備しても良く、ケーブル接続部は、回転防止突出部の係止部と係止する係止部を具備するものであっても良い。 The antenna base may be provided with an anti-rotation protrusion that protrudes from the surface on the vehicle roof side and has an engaging portion, and the cable connection portion is an engaging portion that engages with the engaging portion of the anti-rotation protruding portion. May be provided.
本発明の車両用ルーフマウントアンテナ装置には、車両ルーフに確実に仮固定され、仮止め部の設計自由度も高いという利点がある。 The roof mount antenna device for a vehicle according to the present invention has an advantage that it is surely temporarily fixed to the vehicle roof and has a high degree of freedom in designing the temporary fixing portion.
以下、本発明を実施するための形態を図示例と共に説明する。図１は、本発明の車両用ルーフマウントアンテナ装置を説明するための斜視図であり、図２はその断面図、図３はその底面図である。図中、同一の符号を付した部分は同一物を表わしている。図示の通り、本発明の車両用ルーフマウントアンテナ装置は、アンテナベース１０と、管状脚部２０と、仮止め部３０とから主に構成されている。車両用ルーフマウントアンテナ装置は、車両ルーフＲの設置孔Ｈに仮固定される。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described together with illustrated examples. FIG. 1 is a perspective view for explaining a vehicle roof mount antenna device of the present invention, FIG. 2 is a sectional view thereof, and FIG. 3 is a bottom view thereof. In the figure, the same reference numerals denote the same parts. As shown in the figure, the vehicle roof mount antenna device of the present invention is mainly composed of an antenna base 10, a tubular leg portion 20, and a temporary fixing portion 30. The vehicle roof mount antenna device is temporarily fixed to the installation hole H of the vehicle roof R.
アンテナベース１０は、板状のものである。そして、アンテナベース１０を覆うように、アンテナカバー（図示せず）が設けられる。図示例では、具体的には、アンテナロッドへの導通を確保するための導電板１１が樹脂にインサート成型されたものを示した。そして、ねじ１２がアンテナベースを貫通するように配置されている。このねじ１２は、車両ルーフＲを挟むように後にナットにより車両室内側から締結されるものである。なお、図示例ではねじ１２のねじ頭をアンテナベース１０側に設ける例を示したが、本発明はこれに限定されず、アンテナベース１０側にナットやねじ穴を設け、後にねじにより車両室内側から締結される構成であっても良い。また、ねじやナットは、インサート成型により樹脂と一体的に設けられていても良い。さらに、アンテナベース１０は、例えばアンテナ回路基板等のグラウンドとなるように導電性のもので形成されても良い。アンテナ回路基板等がアンテナベース１０に載置される場合には、ねじ１２は中空のねじボス状のもので構成されれば良い。 The antenna base 10 is plate-shaped. An antenna cover (not shown) is provided so as to cover the antenna base 10. In the illustrated example, specifically, the conductive plate 11 for ensuring conduction to the antenna rod is insert-molded in resin. The screw 12 is arranged so as to penetrate the antenna base. This screw 12 is tightened later from the vehicle interior side with a nut so as to sandwich the vehicle roof R. In the illustrated example, the screw head of the screw 12 is provided on the antenna base 10 side. However, the present invention is not limited to this, and a nut or screw hole is provided on the antenna base 10 side. The structure fastened from may be sufficient. Moreover, the screw and nut may be provided integrally with the resin by insert molding. Furthermore, the antenna base 10 may be formed of a conductive material such as an antenna circuit board. When an antenna circuit board or the like is placed on the antenna base 10, the screw 12 may be formed of a hollow screw boss shape.
管状脚部２０は、アンテナベース１０の車両ルーフＲ側の面から突出するものである。図示例では、管状脚部２０は、円筒状の外周形状を有している例を示した。しかしながら、管状脚部２０の外周形状は、車両ルーフＲに設けられる設置孔Ｈの形状に対応して決定されれば良く、例えば設置孔Ｈが４角形状であれば、それに合わせて管状脚部２０の外周形状も４角柱状の外周形状を有するように構成されれば良い。管状脚部２０は、アンテナベース１０に設けられるねじ１２の外周を囲むように、所定の間隔を開けて設けられている。この所定の間隔は、後述のケーブル接続部の管状突出部の肉厚に合わせて決定されれば良い。管状脚部２０は管状であるため、車両ルーフＲの設置孔Ｈに挿入時に変形しづらい。また、管状脚部２０は、その外周先端が面カットされても良い。これにより、設置孔Ｈへ挿入しやすくなっている。 The tubular leg portion 20 projects from the surface of the antenna base 10 on the vehicle roof R side. In the example of illustration, the tubular leg part 20 showed the example which has a cylindrical outer periphery shape. However, the outer peripheral shape of the tubular leg portion 20 may be determined in accordance with the shape of the installation hole H provided in the vehicle roof R. For example, if the installation hole H is a quadrangular shape, the tubular leg portion is adjusted accordingly. The outer peripheral shape of 20 should just be comprised so that it may have a quadrangular prism-shaped outer peripheral shape. The tubular legs 20 are provided with a predetermined interval so as to surround the outer periphery of the screw 12 provided on the antenna base 10. The predetermined interval may be determined in accordance with the thickness of a tubular projecting portion of a cable connecting portion described later. Since the tubular leg 20 is tubular, it is difficult to be deformed when inserted into the installation hole H of the vehicle roof R. Further, the tubular leg portion 20 may have a surface cut at the outer periphery tip. This facilitates insertion into the installation hole H.
そして、本発明の車両用ルーフマウントアンテナ装置の最も特徴的な部分である仮止め部３０は、管状脚部２０の先端近傍からアンテナベース１０側に延在している。また、仮止め部３０は、管状脚部２０の先端近傍を支点に撓み可能に構成されている。即ち、仮止め部３０は、管状脚部２０の先端近傍側が固定されると共に、アンテナベース１０側が管状脚部２０の内側方向に移動可能に構成されている。図示例では、仮止め部３０を２箇所に設けた例を示したが、本発明はこれに限定されず、仮固定可能な個数あれば良く、最低１か所でも良いし、より多く設けても良い。そして、仮止め部３０は、車両ルーフＲに設けられる設置孔Ｈに係止するための係止爪３１を仮止め部の先端側に有している。仮止め部３０は、管状脚部２０が設置孔Ｈを貫通する際に管状脚部２０内側方向に撓み、貫通後に元の位置に戻り設置孔Ｈに係止する。この際、仮に製造誤差等により、仮止め部３０が外側に撓んでいたとしても、管状脚部２０の先端近傍に仮止め部３０は固定されており、常にフラットな状態であるため、挿入時に仮止め部３０が折れ曲がる等のおそれはない。また、このような構成により、仮止め部３０の長さは、車両ルーフＲの厚み等には影響を受けず、仮止め部３０の撓む距離や剛性等を基に仮止め部３０の長さを決定することが可能となる。 And the temporary fix | stop part 30 which is the most characteristic part of the roof mount antenna apparatus for vehicles of this invention is extended to the antenna base 10 side from the front-end | tip vicinity of the tubular leg part 20. As shown in FIG. Further, the temporary fixing portion 30 is configured to be able to bend with the vicinity of the tip of the tubular leg portion 20 as a fulcrum. That is, the temporary fixing portion 30 is configured such that the vicinity of the distal end of the tubular leg portion 20 is fixed and the antenna base 10 side is movable inward of the tubular leg portion 20. In the illustrated example, an example in which the temporary fixing portions 30 are provided in two places has been shown. However, the present invention is not limited to this, and any number that can be temporarily fixed may be used, and at least one place may be provided. Also good. And the temporary fix part 30 has the latching claw 31 for latching to the installation hole H provided in the vehicle roof R in the front end side of a temporary fix part. The temporary fixing portion 30 bends toward the inside of the tubular leg portion 20 when the tubular leg portion 20 penetrates the installation hole H, returns to the original position after the penetration, and is locked to the installation hole H. At this time, even if the temporary fixing portion 30 is bent outward due to a manufacturing error or the like, the temporary fixing portion 30 is fixed near the tip of the tubular leg portion 20 and is always flat. There is no fear that the temporary fixing portion 30 is bent. Further, with such a configuration, the length of the temporary fixing portion 30 is not affected by the thickness of the vehicle roof R, and the length of the temporary fixing portion 30 is based on the bending distance or rigidity of the temporary fixing portion 30. It is possible to determine the length.
このような構成の本発明の車両用ルーフマウントアンテナ装置を車両ルーフに設置する際には、車両ルーフＲの設置孔Ｈに、アンテナベース１０から突出する管状脚部２０を挿通する。このとき、管状脚部２０に設けられた仮止め部３０が、管状脚部２０の先端近傍を支点に管状脚部２０の内側方向に撓み、貫通後に元の位置に戻り係止爪３１が設置孔Ｈに係止する。これにより車両用ルーフマウントアンテナ装置は車両ルーフＲに仮止めされる。そして、車両室内側からねじ１２に対応するナット等によりねじ締めし、完全に固定される。 When the vehicle roof mount antenna device of the present invention having such a configuration is installed on the vehicle roof, the tubular leg portion 20 protruding from the antenna base 10 is inserted into the installation hole H of the vehicle roof R. At this time, the temporary fixing portion 30 provided in the tubular leg portion 20 bends in the inner direction of the tubular leg portion 20 with the vicinity of the distal end of the tubular leg portion 20 as a fulcrum, returns to the original position after the penetration, and the locking claw 31 is installed. Lock in hole H. Thus, the vehicle roof mount antenna device is temporarily fixed to the vehicle roof R. Then, it is screwed from the vehicle interior side with a nut or the like corresponding to the screw 12 and is completely fixed.
このように、本発明の車両用ルーフマウントアンテナ装置は、仮止め部が管状脚部の先端側からアンテナベース側に延在し、管状脚部の先端近傍を支点に撓み可能に構成されることで、その長さの設計自由度が高くなった。したがって、所望の剛性を有する仮止め部を容易に設計することが可能となり、また、省スペース化も可能となる。そして、剛性を高くすることが可能となるため、仮止め部が内側に撓んだまま曲がり癖が付いてしまうようなことも防止可能であり、確実に車両ルーフに仮固定されることになる。 As described above, the vehicle roof mount antenna device of the present invention is configured such that the temporary fixing portion extends from the distal end side of the tubular leg portion to the antenna base side and can be bent around the distal end of the tubular leg portion as a fulcrum. And the design freedom of the length became high. Therefore, it is possible to easily design a temporary fixing portion having a desired rigidity, and it is possible to save space. And since it becomes possible to make rigidity high, it can also prevent that a temporary fixing | fixed part is bent inside, and it will be able to prevent a bend and it will be temporarily fixed to a vehicle roof reliably. .
次に、車両内部から車両用ルーフマウントアンテナ装置にケーブルを接続するためのケーブル接続部を有する例について、図４乃至図６を用いて説明する。図４は、本発明の車両用ルーフマウントアンテナ装置のケーブル接続部を説明するための斜視図であり、図５及び図６は管状脚部とケーブル接続部が嵌合する状態を説明するための断面図である。図中、図１等と同一の符号を付した部分は同一物を表わしている。図示例では、本発明の車両用ルーフマウントアンテナ装置は、車両室内から車両用ルーフマウントアンテナ装置にケーブルを接続するためのケーブル接続部５０を具備している。ケーブル接続部５０は、管状脚部２０が設置孔Ｈを貫通後に車両室内側から嵌合されるものである。そして、ケーブル接続部５０は、アンテナベース１０側の面から突出し管状脚部２０の内側に嵌合する管状突出部５１を有している。また、ケーブル接続部５０には、例えばケーブルのグラウンド線に接続される、アース爪５２が設けられており、ナット６０によりねじ締めされると、アース爪５２が車両ルーフＲに食い込み、車両ルーフＲに電気的に接地されることになる。 Next, an example having a cable connecting portion for connecting a cable from the inside of the vehicle to the vehicle roof mount antenna device will be described with reference to FIGS. FIG. 4 is a perspective view for explaining a cable connecting portion of the vehicle roof mount antenna device of the present invention, and FIGS. 5 and 6 are for explaining a state in which the tubular leg portion and the cable connecting portion are fitted together. It is sectional drawing. In the figure, the same reference numerals as those in FIG. In the illustrated example, the vehicle roof mount antenna device of the present invention includes a cable connecting portion 50 for connecting a cable from the vehicle interior to the vehicle roof mount antenna device. The cable connection portion 50 is fitted from the vehicle interior side after the tubular leg portion 20 has penetrated the installation hole H. The cable connecting portion 50 has a tubular projecting portion 51 that projects from the surface on the antenna base 10 side and fits inside the tubular leg portion 20. The cable connection portion 50 is provided with a ground claw 52 that is connected to, for example, a cable ground line. When the nut 60 is screwed, the ground claw 52 bites into the vehicle roof R, and the vehicle roof R Is electrically grounded.
図４に示される通り、ケーブル接続部５０の管状突出部５１は、図３に示されるような管状脚部２０の内周形状に対応させて、その外周形状が形成されれば良い。例えば、管状突出部５１を管状脚部２０に挿入する角度が所定方向に固定されるように構成する場合には、管状脚部２０の内周形状及び管状突出部５１の外周形状は、挿入方向を軸とする回転方向で回転制限を受ける形状とすれば良い。より具体的には、図３に示されるように、管状脚部２０の内周形状は、例えば８角形状に形成されている。そして、図４に示されるように、管状突出部５１の外周形状は、これに対応させて８角形状に形成されている。なお、本発明において、ケーブル接続部５０を所定方向に固定されるように構成する場合には、図示例のような多角形状には限定されず、回転制限を受ける形状であれば良い。このように構成すると、管状脚部２０とケーブル接続部５０との接続角度が確実に特定の方向に決定されるため、正しい位置に嵌合可能となる。なお、ケーブル接続部が所定方向に固定されない構成とする場合には、管状脚部２０とケーブル接続部５０の形状は、円形状とすれば良い。 As shown in FIG. 4, the tubular projecting portion 51 of the cable connecting portion 50 may have an outer peripheral shape corresponding to the inner peripheral shape of the tubular leg portion 20 as shown in FIG. 3. For example, when the tubular protrusion 51 is configured such that the angle at which the tubular protrusion 51 is inserted into the tubular leg 20 is fixed in a predetermined direction, the inner peripheral shape of the tubular leg 20 and the outer peripheral shape of the tubular protrusion 51 are the insertion direction. What is necessary is just to make it the shape which receives a rotation restriction | limiting in the rotation direction centering on. More specifically, as shown in FIG. 3, the inner peripheral shape of the tubular leg portion 20 is formed in an octagonal shape, for example. And as FIG. 4 shows, the outer peripheral shape of the tubular protrusion part 51 is formed in the octagon shape corresponding to this. In the present invention, when the cable connection portion 50 is configured to be fixed in a predetermined direction, the shape is not limited to the polygonal shape as shown in the illustrated example, and may be a shape subject to rotation restriction. If comprised in this way, since the connection angle of the tubular leg part 20 and the cable connection part 50 is decided in a specific direction reliably, it becomes possible to fit in the correct position. In addition, when it is set as the structure which a cable connection part is not fixed to a predetermined direction, the shape of the tubular leg part 20 and the cable connection part 50 should just be circular shape.
また、管状突出部５１の外周先端は、面カットされていても良い。面カットされることにより、管状脚部２０への挿入が容易となると共に、面カットの部分から８角形状の部分にかけてスムーズに特定の方向に回転しながらケーブル接続部５０が管状脚部２０に嵌合されることになる。 Moreover, the outer periphery front-end | tip of the tubular protrusion part 51 may be surface-cut. By cutting the surface, the insertion into the tubular leg portion 20 is facilitated, and the cable connecting portion 50 is connected to the tubular leg portion 20 while smoothly rotating in a specific direction from the surface cut portion to the octagonal portion. Will be fitted.
図５に示される通り、管状脚部２０が設置孔Ｈを貫通後、仮止め部３０が元の位置に戻り設置孔Ｈに係止した状態で、管状突出部５１が、管状脚部２０の内側、より具体的には、管状脚部２０とねじ１２の間の所定の間隔のところに嵌合していく。即ち、管状突出部５１の肉厚は、この所定の間隔に合わせたものとなっている。その後、図６に示されるように、管状突出部５１が完全に管状脚部２０に嵌合する。図示の通り、管状突出部５１は、仮止め部３０が管状脚部２０の内側方向に撓まないように、仮止め部３０を管状脚部２０の内側から支えるように構成されている。これにより、仮に管状脚部２０の設置孔Ｈへの挿入が甘く、仮止め部３０が撓んだまま元の形状に戻っていない場合であっても、管状突出部５１を挿入することにより、管状突出部５１が仮止め部３０の支点側から仮止め部３０を元の形状に戻すように押し広げていくことになるため、確実に仮止め部３０を正しい位置に持っていくことが可能となる。 As shown in FIG. 5, after the tubular leg 20 has penetrated the installation hole H, the tubular protrusion 51 is formed on the tubular leg 20 in a state where the temporary fixing part 30 returns to the original position and is locked to the installation hole H. It fits inside, more specifically, at a predetermined distance between the tubular leg 20 and the screw 12. That is, the wall thickness of the tubular projecting portion 51 is adjusted to this predetermined interval. Thereafter, as shown in FIG. 6, the tubular protrusion 51 is completely fitted to the tubular leg 20. As illustrated, the tubular protruding portion 51 is configured to support the temporary fixing portion 30 from the inside of the tubular leg portion 20 so that the temporary fixing portion 30 does not bend in the inner direction of the tubular leg portion 20. Thereby, even if it is a case where insertion into the installation hole H of the tubular leg portion 20 is sweet and the temporary fixing portion 30 is not bent and returned to the original shape, by inserting the tubular protrusion 51, Since the tubular projecting portion 51 is pushed out from the fulcrum side of the temporary fixing portion 30 so as to return the temporary fixing portion 30 to its original shape, the temporary fixing portion 30 can be surely brought to the correct position. It becomes.
このように、本発明の車両用ルーフマウントアンテナ装置は、仮止め部３０を管状脚部２０の先端近傍を支点に撓み可能に構成したことにより、仮止め部３０が撓んだまま元の形状に仮に戻っていなかったとしても、ケーブル接続部５０の管状突出部５１が管状脚部の先端側から嵌合され、仮止め部３０の支点側から元の形状に押し戻されることで、確実に固定されることになる。 As described above, the roof mounting antenna device for a vehicle according to the present invention is configured such that the temporary fixing portion 30 can be bent with the vicinity of the distal end of the tubular leg portion 20 as a fulcrum, so that the temporary fixing portion 30 remains bent. Even if it has not been temporarily returned, the tubular projecting portion 51 of the cable connecting portion 50 is fitted from the distal end side of the tubular leg portion, and is pushed back to the original shape from the fulcrum side of the temporary fastening portion 30 to be securely fixed. Will be.
