The open end of the first notch 723 at the second end 72d is formed such that the opening widens as it approaches the end surface of the second end 72d. The second notch part 724 is formed in the main body part 720 along the circumferential direction of the cylinder part 72. The second notch 724 is connected to the first notch 723 on the first end 72 c side of the main body 720 in the first notch 723. The width of the second notch portion 724 in the vertical direction is larger than the outer diameter of each shaft portion of the screws 64 and 65.

本体部７２０は、筒部７２の周方向において、第２切欠き部７２４の第１切欠き部７２３側に形成されている突部７５を更に有する。突部７５は、先端側ほど筒部７２の周方向の幅が狭くなるように、先細りした形状である。突部７５では、第１切欠き部７２３側の面とは反対側の面が筒部７２の軸方向に平行であり、この反対側の面と切欠き部７２３側の面とで決まる内角が鋭角である。突部７５は、第２切欠き部７２４の一部を塞ぐ。図７における右側の第１嵌合部材７１ａは、施工時に、第１嵌合部材７１ａの下方から見てポール１０の外面の回りで反時計回りに回転可能である。これにより、第１切欠き部７２３を通されていたねじ６４の軸部の一部を第２切欠き部７２４内に収容することができる。突部７５は、第２切欠き部７２４に軸部の一部が収容されたねじ６４が第２切欠き部７２４から出て第１切欠き部７２３に入るのを抑制する。ここにおいて、突部７５は、ねじ６４が突部７５に当たることで、第１嵌合部材７１ａの下方から見て時計回りに回転する第１嵌合部材７１ａの移動を規制する。   The main body 720 further includes a protrusion 75 formed on the first notch 723 side of the second notch 724 in the circumferential direction of the cylindrical portion 72. The protrusion 75 has a tapered shape so that the width in the circumferential direction of the cylindrical portion 72 becomes narrower toward the distal end side. In the protrusion 75, the surface opposite to the surface on the first notch 723 side is parallel to the axial direction of the cylindrical portion 72, and the inner angle determined by the surface on the opposite side and the surface on the notch 723 side is It is an acute angle. The protrusion 75 closes a part of the second notch 724. The first fitting member 71a on the right side in FIG. 7 can rotate counterclockwise around the outer surface of the pole 10 when viewed from below the first fitting member 71a during construction. Accordingly, a part of the shaft portion of the screw 64 that has been passed through the first cutout portion 723 can be accommodated in the second cutout portion 724. The protrusion 75 prevents the screw 64 having a part of the shaft portion accommodated in the second notch 724 from coming out of the second notch 724 and entering the first notch 723. Here, the protrusion 75 restricts the movement of the first fitting member 71a that rotates clockwise as viewed from below the first fitting member 71a when the screw 64 hits the protrusion 75.

また、図７における左側の第２嵌合部材７１ｂは、施工時に、第２嵌合部材７１ｂの下方から見てポール１０の外面の回りで反時計回りに回転可能である。これにより、第１切欠き部７２３を通されていたねじ６５の軸部を第２切欠き部７２４内に収容することができる。突部７５は、第２切欠き部７２４に軸部の一部が収容されたねじ６５が第２切欠き部７２４から出て第１切欠き部７２３に入るのを抑制する。ここにおいて、ねじ６５が突部７５に当たることで、第２嵌合部材７１ｂの下方から見て時計回りに回転する第２嵌合部材７１ｂの移動を規制する。   Further, the left second fitting member 71b in FIG. 7 can rotate counterclockwise around the outer surface of the pole 10 when viewed from below the second fitting member 71b during construction. Accordingly, the shaft portion of the screw 65 that has been passed through the first notch portion 723 can be accommodated in the second notch portion 724. The protrusion 75 prevents the screw 65 in which a part of the shaft portion is accommodated in the second notch 724 from coming out of the second notch 724 and entering the first notch 723. Here, when the screw 65 hits the protrusion 75, the movement of the second fitting member 71b that rotates clockwise as viewed from the lower side of the second fitting member 71b is restricted.

例えば、ねじ６４が第１切欠き部７２３から第２切欠き部７２４に移動する場合、突部７５の先端がねじ６４に接触しながら第２切欠き部７２４側に弾性変形する。突部７５がねじ６４から離れると、突部７５の先端は、弾性によって、元の位置に戻る。ねじ６４及びねじ６５の各々が第２切欠き部７２４の各々の軸部の一部が収容されている状態において、シール部材７は、取付部材５及びポール１０に保持される。また、ねじ６４及びねじ６５の各々が第２切欠き部７２４に挿入される状態において、シール部材７の脱落が防止される。   For example, when the screw 64 moves from the first notch 723 to the second notch 724, the tip of the protrusion 75 is elastically deformed toward the second notch 724 while contacting the screw 64. When the protrusion 75 is separated from the screw 64, the tip of the protrusion 75 returns to its original position due to elasticity. The seal member 7 is held by the attachment member 5 and the pole 10 in a state where each of the screw 64 and the screw 65 accommodates a part of the shaft portion of the second notch 724. Further, in a state where each of the screw 64 and the screw 65 is inserted into the second notch 724, the seal member 7 is prevented from falling off.

２つの弧状鍔部７３０の各々は、本体部７２０の第１端７２ｃの外周縁の全周に亘って、筒部７２の径方向外向きに突出する。図８Ａ及び図８Ｂに示すように、弧状鍔部７３０は、第１面７３ａと、第２面７３ｂと、第３面７３ｃとを有する。第１面７３ａは、本体部７２０の外面７２０ｂと繋がっている。第１面７３ａは、本体部７２０の外面７２０ｂから離れるにつれて下方に傾斜する。ここでは、２つの弧状鍔部７３０の各々の第１面７３ａは、小リブ部５３１の下端面５１６（図４及び図６参照）に沿った形状に形成されていることが好ましい。第２面７３ｂは、第１端７２ｃの端面に、第１端７２ｃの端面と平面状に繋がっている。第３面７３ｃは、第２筒部５２の下端の内周面に沿った形状である。第３面７３ｃの曲率半径は、第２筒部５２の下端の内周面の曲率半径と略同じである。２つの弧状鍔部７３０の各々の第２面７３ｂには、図８Ａに示すように、丸穴７３１が形成される。丸穴７３１は、嵌合部材７１をポール１０の外面に沿って移動させる際にドライバなどの先端を挿入させることが可能な大きさに形成されていることが好ましい。丸穴７３１は、筒部７２の軸方向と平行な方向において、第１切欠き部７２３と一直線上に形成されることが好ましい。これにより、施工者が、シール部材７を取付部材５とポール１０との隙間５０３に入れるときに第１切欠き部７２３とねじ６４又はねじ６５とを位置合わせするための目印として丸穴７３１を利用することができる。   Each of the two arcuate flange portions 730 protrudes outward in the radial direction of the cylindrical portion 72 over the entire outer periphery of the first end 72 c of the main body portion 720. As shown in FIGS. 8A and 8B, the arcuate collar 730 has a first surface 73a, a second surface 73b, and a third surface 73c. The first surface 73a is connected to the outer surface 720b of the main body 720. The first surface 73a is inclined downward as it is away from the outer surface 720b of the main body 720. Here, it is preferable that the first surface 73a of each of the two arc-shaped flange portions 730 is formed in a shape along the lower end surface 516 of the small rib portion 531 (see FIGS. 4 and 6). The second surface 73b is connected to the end surface of the first end 72c in a planar manner with the end surface of the first end 72c. The third surface 73 c has a shape along the inner peripheral surface at the lower end of the second cylindrical portion 52. The curvature radius of the third surface 73 c is substantially the same as the curvature radius of the inner peripheral surface at the lower end of the second cylindrical portion 52. As shown in FIG. 8A, a round hole 731 is formed in the second surface 73b of each of the two arcuate flanges 730. The round hole 731 is preferably formed in a size that allows a tip of a driver or the like to be inserted when the fitting member 71 is moved along the outer surface of the pole 10. The round hole 731 is preferably formed in a straight line with the first notch portion 723 in a direction parallel to the axial direction of the cylindrical portion 72. Thereby, when the installer puts the seal member 7 into the gap 503 between the mounting member 5 and the pole 10, the round hole 731 is used as a mark for aligning the first notch 723 and the screw 64 or the screw 65. Can be used.

図１０Ａ、図１０Ｂ、図１０Ｃ、図１０Ｄ、及び図１０Ｅを参照して、小ポール１０ｂに照明器具１を取り付ける方法について説明する。下記の取付方法は、一例であって、これに限定されない。   With reference to FIG. 10A, FIG. 10B, FIG. 10C, FIG. 10D, and FIG. 10E, the method to attach the lighting fixture 1 to the small pole 10b is demonstrated. The following attachment method is an example and is not limited to this.

施工者は、器具本体３における取付部材５に小ポール１０ｂの第２端１０２が挿入されるように、小ポール１０ｂの第２端１０２側から第１端１０１側に向かって器具本体３を移動させる。ここにおいて、施工者は、小ポール１０ｂの上端面１０３と取付部材５の各第２ボス５５ｂの下端面とが接触するまで、器具本体３を小ポール１０ｂの第１端１０１側に向かって移動させる。このとき、小ポール１０ｂの上端面１０３が第２ボス５５ｂの下端面に接触することで、小ポール１０ｂの第２端１０２の一部は、複数の大リブ部５３３の先端面に接触した状態で第２筒部５２に収納される。小ポール１０ｂの上端面１０３が複数の第２ボス５５ｂの下端面に接触することで、小ポール１０ｂの第１端１０１側に向かう方向への器具本体３の移動が規制される。   The installer moves the instrument body 3 from the second end 102 side of the small pole 10b toward the first end 101 side so that the second end 102 of the small pole 10b is inserted into the mounting member 5 in the instrument body 3. Let Here, the installer moves the instrument body 3 toward the first end 101 side of the small pole 10b until the upper end surface 103 of the small pole 10b comes into contact with the lower end surface of each second boss 55b of the mounting member 5. Let At this time, the upper end surface 103 of the small pole 10b is in contact with the lower end surface of the second boss 55b, so that a part of the second end 102 of the small pole 10b is in contact with the front end surfaces of the plurality of large rib portions 533. And is stored in the second cylindrical portion 52. When the upper end surface 103 of the small pole 10b contacts the lower end surfaces of the plurality of second bosses 55b, the movement of the instrument body 3 in the direction toward the first end 101 of the small pole 10b is restricted.

次に、施工者は、２つのねじ孔５１４のうち取付部材５の下端面５０１側のねじ孔５１４に保持されているねじ６４を、ねじ６４の先端が小ポール１０ｂの外面に接触するまで回す。施工者は、ねじ孔５１５に保持されているねじ６５を、ねじ６５の先端が小ポール１０ｂの外面に接触するまで回す。さらに、２つのねじ孔５１４のうち下端面５０１から離れたねじ孔５１４にねじ６４を、ねじ６４の先端が小ポール１０ｂの外面に接触するまで回す。２つのねじ６４及びねじ６５がそれぞれの軸部において、ねじ孔５１４，５１５に嵌め合わされている部位を適宜変えることで、小ポール１０ｂの軸方向と第２筒部５２の軸方向とが同じになるように、器具本体３が小ポール１０ｂに取り付けられる（図１０Ａ参照）。   Next, the installer turns the screw 64 held in the screw hole 514 on the lower end surface 501 side of the mounting member 5 out of the two screw holes 514 until the tip of the screw 64 contacts the outer surface of the small pole 10b. . The installer turns the screw 65 held in the screw hole 515 until the tip of the screw 65 contacts the outer surface of the small pole 10b. Further, the screw 64 is rotated in the screw hole 514 that is distant from the lower end surface 501 of the two screw holes 514 until the tip of the screw 64 contacts the outer surface of the small pole 10b. The axial direction of the small pole 10b and the axial direction of the second cylindrical portion 52 are made the same by appropriately changing the portion where the two screws 64 and 65 are fitted in the screw holes 514 and 515 in the respective shaft portions. Thus, the instrument body 3 is attached to the small pole 10b (see FIG. 10A).

次に、施工者は、２つの嵌合部材７１のうち一方の嵌合部材７１（以下、第１嵌合部材７１ａと呼ぶ）を、取付部材５の下方で小ポール１０ｂの外面に押さえつけて、本体部７２０の内面７２０ａを小ポール１０ｂの外面に接触させる。そして、施工者は、図１０Ｂに示すように、２つの嵌合部材７１のうち他方の嵌合部材７１（以下、第２嵌合部材７１ｂと呼ぶ）の本体部７２０の内面７２０ａを小ポール１０ｂの外面に沿わせながら、第２嵌合部材７１ｂの第１嵌合部７２１と第１嵌合部材７１ａの第２嵌合部７２２とを近づける。その後、施工者は、図１０Ｃに示すように、第１嵌合部材７１ａと第２嵌合部材７１ｂとを互いに嵌め合わせてシール部材７を形成し、このシール部材７を取付部材５の下方から取付部材５に近づける。   Next, the installer presses one of the two fitting members 71 (hereinafter referred to as the first fitting member 71a) against the outer surface of the small pole 10b below the attachment member 5, The inner surface 720a of the main body 720 is brought into contact with the outer surface of the small pole 10b. Then, as shown in FIG. 10B, the contractor sets the inner surface 720a of the body portion 720 of the other fitting member 71 (hereinafter referred to as the second fitting member 71b) of the two fitting members 71 to the small pole 10b. The first fitting portion 721 of the second fitting member 71b and the second fitting portion 722 of the first fitting member 71a are brought closer to each other along the outer surface of the first fitting member 71b. Thereafter, as shown in FIG. 10C, the contractor fits the first fitting member 71 a and the second fitting member 71 b together to form the seal member 7, and this seal member 7 is moved from below the attachment member 5. Approach the mounting member 5.

次に、施工者は、丸穴７３１とねじ６４とが筒部７２の軸方向と平行な方向において略一直線上に並ぶように位置合わせしてから、シール部材７を器具本体３の取付部材５と小ポール１０ｂとの間の隙間５０３に挿入する（図１０Ｄ参照）。このとき、施工者は、ねじ６４及びねじ６５の各々が第１切欠き部７２３に挿入されて、本体部７２０の第１端７２ｃ側における第１切欠き部７２３の縁部に接触するまで、シール部材７を上側に移動させる。その後、施工者は、小ポール１０ｂの第１端１０１側からシール部材７を見て、シール部材７を反時計回りに回転させる（図１０Ｅ参照）。このとき、施工者は、ドライバなどの先端を２つの丸穴７３１のうち少なくとも一方の丸穴７３１に挿入させて、シール部材７を小ポール１０ｂの回りで回転させる。そして、施工者は、ねじ６４及びねじ６５の各々の軸部が、筒部７２の周方向における第２切欠き部７２４の縁部に当たるまで第２切欠き部７２４に入れる（図７参照）。   Next, the installer positions the seal member 7 so that the round hole 731 and the screw 64 are aligned in a substantially straight line in a direction parallel to the axial direction of the cylindrical portion 72, and then attaches the seal member 7 to the attachment member 5 of the instrument body 3. And the small pole 10b are inserted into the gap 503 (see FIG. 10D). At this time, the contractor inserts each of the screw 64 and the screw 65 into the first cutout portion 723 until it contacts the edge portion of the first cutout portion 723 on the first end 72c side of the main body portion 720. The seal member 7 is moved upward. Thereafter, the installer looks at the seal member 7 from the first end 101 side of the small pole 10b and rotates the seal member 7 counterclockwise (see FIG. 10E). At this time, the installer inserts the tip of a driver or the like into at least one of the two round holes 731 and rotates the seal member 7 around the small pole 10b. Then, the installer puts each shaft portion of the screw 64 and the screw 65 into the second cutout portion 724 until the shaft portion hits the edge of the second cutout portion 724 in the circumferential direction of the cylindrical portion 72 (see FIG. 7).

本実施形態の照明器具１では、シール部材７を使用することで、すでに設置された小ポール１０ｂに、器具本体３が取り付けられた状態において器具本体３を小ポール１０ｂから取り外さずに、シール部材７で隙間５０３を塞ぐことができる。また、シール部材７は、互いに同じ形状の２つの嵌合部材７１で構成されているので、生産性の向上が期待できる。   In the lighting fixture 1 of this embodiment, by using the seal member 7, the seal member can be used without removing the fixture body 3 from the small pole 10b in a state where the fixture body 3 is attached to the already installed small pole 10b. 7 can close the gap 503. Further, since the seal member 7 is composed of two fitting members 71 having the same shape, an improvement in productivity can be expected.

以上説明したように、本実施形態のシール部材７は、複数の嵌合部材７１を備える。複数の嵌合部材７１は、長手方向の第１端１０１及び第２端１０２を有するポール１０（小ポール１０ｂ）における第２端１０２の外面とポール１０の第２端１０２を覆う照明器具１においてポール１０の第２端１０２の外面に対向する面（取付部材５における第２筒部５２の内周面）との間の隙間５０３に配置される。複数の嵌合部材７１は、互いに嵌合されることで、筒部７２と筒部７２の軸方向の一端（第１端）７２ｃにおいて筒部７２の周方向の全周に亘って筒部７２の外方に突出する鍔部７３とを有する形状となる。複数の嵌合部材７１は、同一形状である。複数の嵌合部材７１は、筒部７２の周方向に交差する２つの端面（第１端面７２ａ及び第２端面７２ｂ）を有する。これにより、シール部材７は、照明器具１の一部とポール１０の外面（第２端１０２の外面）との間の隙間５０３を塞ぐことが可能である。   As described above, the seal member 7 of this embodiment includes a plurality of fitting members 71. In the lighting fixture 1 that covers the outer surface of the second end 102 and the second end 102 of the pole 10 in the pole 10 (small pole 10b) having the first end 101 and the second end 102 in the longitudinal direction. It arrange | positions in the clearance gap 503 between the surfaces (inner peripheral surface of the 2nd cylinder part 52 in the attachment member 5) which opposes the outer surface of the 2nd end 102 of the pole 10. FIG. When the plurality of fitting members 71 are fitted to each other, the cylindrical portion 72 extends over the entire circumference in the circumferential direction of the cylindrical portion 72 at one end (first end) 72c of the cylindrical portion 72 and the cylindrical portion 72 in the axial direction. It becomes the shape which has the collar part 73 which protrudes outward. The plurality of fitting members 71 have the same shape. The plurality of fitting members 71 have two end surfaces (a first end surface 72 a and a second end surface 72 b) that intersect the circumferential direction of the cylindrical portion 72. Thereby, the seal member 7 can block the gap 503 between a part of the lighting fixture 1 and the outer surface of the pole 10 (the outer surface of the second end 102).

シール部材７では、複数の嵌合部材７１ａ，７１ｂの各々が、２つの端面のうち一方の端面である第１端面７２ａに形成されている第１嵌合部７２１を備えることが好ましい。また、複数の嵌合部材７１ａ，７１ｂの各々が、２つの端面のうち他方の端面である第２端面７２ｂに形成されている第２嵌合部７２２を備えることが好ましい。複数の嵌合部材７１ａ，７１ｂのうち筒部７２の周方向において隣り合う２つの嵌合部材７１ａ，７１ｂの一方の嵌合部材７１ａの第１嵌合部７２１と、他方の嵌合部材７１ｂの第２嵌合部７２２とが嵌合可能であることが好ましい。これにより、シール部材７では、筒部７２の周方向において隣り合う２つの嵌合部材７１ａ、７１ｂが、互いに容易に外れ難くなる。   In the seal member 7, each of the plurality of fitting members 71a and 71b preferably includes a first fitting portion 721 formed on a first end surface 72a that is one of the two end surfaces. In addition, each of the plurality of fitting members 71a and 71b preferably includes a second fitting portion 722 formed on the second end surface 72b which is the other end surface of the two end surfaces. Of the plurality of fitting members 71a, 71b, the first fitting portion 721 of one fitting member 71a of two fitting members 71a, 71b adjacent in the circumferential direction of the cylindrical portion 72 and the other fitting member 71b. It is preferable that the second fitting portion 722 can be fitted. Thereby, in the seal member 7, the two fitting members 71a and 71b adjacent in the circumferential direction of the cylindrical portion 72 are not easily detached from each other.

シール部材７では、第１嵌合部７２１が、第１端面７２ａから筒部７２の周方向に沿った方向に突出した凸部であり、第２嵌合部７２２が、第２端面７２ｂに形成された凹部であることが好ましい。これにより、シール部材７では、筒部７２の周方向いおいて隣り合う２つの嵌合部材７１ａ、７１ｂの上下方向における移動が規制される。   In the seal member 7, the first fitting portion 721 is a convex portion protruding from the first end surface 72a in the direction along the circumferential direction of the cylindrical portion 72, and the second fitting portion 722 is formed on the second end surface 72b. It is preferable that it is the recessed part made. Thereby, in the sealing member 7, the movement in the up-down direction of the two fitting members 71a and 71b adjacent in the circumferential direction of the cylindrical portion 72 is restricted.

照明器具１は、ポール１０に対してねじ６４，６５により取り付けられるように構成されていることが好ましい。シール部材７では、複数の嵌合部材７１ａ、７１ｂの各々は、筒部７２の軸方向に平行な方向に沿って形成されており鍔部７３とは反対側が開放された第１切欠き部７２３を備えることが好ましい。複数の嵌合部材７１ａ、７１ｂの各々は、嵌合部材７１ａ、７１ｂにおいて、周方向に沿って形成され第１切欠き部７２３と繋がっている第２切欠き部７２４を更に備えることが好ましい。第１切欠き部７２３及び第２切欠き部７２４の幅はねじ６４，６５の軸部の外径よりも大きいことが好ましい。これにより、シール部材７では、第２切欠き部７２４にねじ６４及びねじ６５が挿入されることにより、筒部７２の軸方向と平行する方向におけるシール部材７の移動が規制される。   It is preferable that the luminaire 1 is configured to be attached to the pole 10 with screws 64 and 65. In the seal member 7, each of the plurality of fitting members 71 a and 71 b is formed along a direction parallel to the axial direction of the cylindrical portion 72, and the first notch portion 723 opened on the side opposite to the flange portion 73. It is preferable to provide. Each of the plurality of fitting members 71a and 71b preferably further includes a second cutout portion 724 formed along the circumferential direction in the fitting members 71a and 71b and connected to the first cutout portion 723. The widths of the first notch 723 and the second notch 724 are preferably larger than the outer diameter of the shafts of the screws 64 and 65. Thereby, in the seal member 7, the screw 64 and the screw 65 are inserted into the second notch 724, whereby the movement of the seal member 7 in the direction parallel to the axial direction of the cylinder portion 72 is restricted.

シール部材７では、複数の嵌合部材７１ａ，７１ｂの各々は、弾性体であることが好ましい。複数の嵌合部材７１ａ，７１ｂの各々は、第２切欠き部７２４における第１切欠き部７２３側で、第２切欠き部７２４の縁部から軸方向に平行する方向に突出した、突部７５を更に備えることが好ましい。これにより、シール部材７では、突部７５の先端がねじ６４に接触しながら第２切欠き部７２４側に弾性変形するので、ねじ６４及びねじ６５が第２切欠き部７２４に挿入可能である。さらに、ねじ６４及びねじ６５が突部７５に当たって、ねじ６４及びねじ６５が第２切欠き部７２４から容易に第１切欠き部７２３に戻ることができないので、シール部材７の脱落を防止することが可能となる。   In the seal member 7, each of the plurality of fitting members 71a and 71b is preferably an elastic body. Each of the plurality of fitting members 71a and 71b protrudes in a direction parallel to the axial direction from the edge of the second notch 724 on the first notch 723 side of the second notch 724. 75 is preferably included. As a result, in the seal member 7, the tip of the protrusion 75 is elastically deformed toward the second notch 724 while contacting the screw 64, so that the screw 64 and the screw 65 can be inserted into the second notch 724. . Furthermore, since the screw 64 and the screw 65 hit the protrusion 75 and the screw 64 and the screw 65 cannot easily return from the second notch 724 to the first notch 723, the seal member 7 is prevented from falling off. Is possible.

照明器具１では、長手方向の第１端及び第２端１０２の外面に対向する面（取付部材５における第２筒部５２の内周面）を有する器具本体３を備える。照明器具１は、器具本体３において、ポール１０の第２端１０２の外面に対向する面と外面との隙間５０３に配置される上述のシール部材７を備える。これにより、照明器具１は、照明器具１の一部とポール１０の外面（第２端１０２の外面）との間の隙間５０３を塞ぐことが可能である。   The lighting fixture 1 includes a fixture main body 3 having a surface (the inner peripheral surface of the second cylindrical portion 52 in the mounting member 5) facing the outer surfaces of the first end and the second end 102 in the longitudinal direction. The luminaire 1 includes the above-described seal member 7 disposed in a gap 503 between a surface of the fixture body 3 that faces the outer surface of the second end 102 of the pole 10 and the outer surface. Thereby, the lighting fixture 1 can block the gap 503 between a part of the lighting fixture 1 and the outer surface of the pole 10 (the outer surface of the second end 102).

The size of the inner diameter of the seal member 7A of Modification 1 of the above embodiment is different from the size of the inner diameter of the seal member 7 of the above embodiment. Regarding the seal member 7A of the first modification, the same reference numerals are given to the same components as those of the above-described embodiment, and detailed description thereof is omitted.

図１１を参照して、中ポール１０ｃにシール部材７Ａを備える照明器具１を取り付ける方法について説明する。下記の取付方法は、一例である。   With reference to FIG. 11, the method to attach the lighting fixture 1 provided with the sealing member 7A to the inside pole 10c is demonstrated. The following attachment method is an example.

施工者は、器具本体３における、取付部材５に中ポール１０ｃの第２端１０２が挿入されるように、中ポール１０ｃの第２端１０２側から第１端１０１側に向かって器具本体３を移動させる。ここにおいて施工者は、中ポール１０ｃの上端面１０３と取付部材５の各大リブ部５３３の下端面とが接触するまで器具本体３を中ポール１０ｃの第１端１０１側に向かって移動させる。このとき、中ポール１０ｃの上端面１０３が大リブ部５３３の下端面に接触することで、中ポール１０ｃの第２端１０２の一部は、複数の大リブ部５３３の先端面に接触した状態で第２筒部５２に収納される。中ポール１０ｃの上端面１０３が複数の大リブ部５３３の下端面に接触することで、中ポール１０ｃの第１端１０１側に向かう方向への器具本体３の移動が規制される。   The installer moves the instrument body 3 from the second end 102 side of the middle pole 10c toward the first end 101 side so that the second end 102 of the middle pole 10c is inserted into the mounting member 5 in the instrument body 3. Move. Here, the installer moves the instrument body 3 toward the first end 101 side of the middle pole 10c until the upper end surface 103 of the middle pole 10c and the lower end surface of each large rib portion 533 of the attachment member 5 come into contact with each other. At this time, the upper end surface 103 of the middle pole 10c is in contact with the lower end surface of the large rib portion 533, so that a part of the second end 102 of the middle pole 10c is in contact with the front end surfaces of the plurality of large rib portions 533. And is stored in the second cylindrical portion 52. When the upper end surface 103 of the middle pole 10c contacts the lower end surfaces of the plurality of large rib portions 533, the movement of the instrument body 3 in the direction toward the first end 101 side of the middle pole 10c is restricted.

次に、施工者は、２つのねじ孔５１４のうち取付部材５の下端面５０１側のねじ孔５１４に保持されているねじ６４を、ねじ６４の先端が中ポール１０ｃの外面に接触するまで回す。施工者は、ねじ孔５１５に保持されているねじ６５を、ねじ６５の先端が中ポール１０ｃの外面に接触するまで回す。さらに、２つのねじ孔５１４のうち下端面５０１から離れたねじ孔５１４にねじ６４を、ねじ６４の先端が中ポール１０ｃの外面に接触するまで回す。２つのねじ６４及びねじ６５がそれぞれの軸部において、ねじ孔５１４，５１５に嵌め合わされている部位を適宜変えることで、中ポール１０ｃの軸方向と第２筒部５２の軸方向とが同じになるように、器具本体３が中ポール１０ｃに取り付けられる。   Next, the installer turns the screw 64 held in the screw hole 514 on the lower end surface 501 side of the mounting member 5 out of the two screw holes 514 until the tip of the screw 64 contacts the outer surface of the middle pole 10c. . The installer turns the screw 65 held in the screw hole 515 until the tip of the screw 65 contacts the outer surface of the middle pole 10c. Further, the screw 64 is rotated into the screw hole 514 that is apart from the lower end surface 501 of the two screw holes 514 until the tip of the screw 64 contacts the outer surface of the middle pole 10c. The axial direction of the middle pole 10c and the axial direction of the second cylindrical portion 52 are made the same by appropriately changing the portion where the two screws 64 and 65 are fitted in the screw holes 514 and 515 in the respective shaft portions. Thus, the instrument main body 3 is attached to the middle pole 10c.

次に、施工者は、第１嵌合部材７１ａを取付部材５の下方で中ポール１０ｃの外面に押さえつけて、本体部７２０の内面７２０ａを中ポール１０ｃの外面に接触させる。そして、施工者は、第２嵌合部材７１ｂの本体部７２０の内面７２０ａを中ポール１０ｃの外面に沿わせながら、第２嵌合部材７１ｂの第１嵌合部７２１と第１嵌合部材７１ａの第２嵌合部７２２とを近づける。その後、施工者は、第１嵌合部材７１ａと第２嵌合部材７１ｂとを互いに嵌め合わせてシール部材７Ａを形成し、このシール部材７Ａを取付部材５の下方から取付部材５に近づける。   Next, the builder presses the first fitting member 71a against the outer surface of the middle pole 10c below the attachment member 5 to bring the inner surface 720a of the main body 720 into contact with the outer surface of the middle pole 10c. Then, the installer places the first fitting portion 721 of the second fitting member 71b and the first fitting member 71a while keeping the inner surface 720a of the main body portion 720 of the second fitting member 71b along the outer surface of the middle pole 10c. The second fitting portion 722 is brought closer. Thereafter, the installer forms the seal member 7 </ b> A by fitting the first fitting member 71 a and the second fitting member 71 b together, and brings the seal member 7 </ b> A closer to the attachment member 5 from below the attachment member 5.
