発光装置1では、上述の固定部3が締められて、底部51がフランジ部23と取付パネル9とに挟まれることにより、保護部材5が、本体部2および取付パネル9に対して固定される。保護部材5の底部51の背面は、フランジ部23により取付パネル9の前面91に向けて押圧される。底部51の前面は、取付パネル9により、ワッシャ61を介してフランジ部23の背面に向けて押圧される。これにより、保護部材5が、本体部2に対して相対的に周方向に回転することを防止(または、抑制)することができる。   In the light emitting device 1, the above-described fixing portion 3 is tightened and the bottom portion 51 is sandwiched between the flange portion 23 and the mounting panel 9, whereby the protective member 5 is fixed to the main body portion 2 and the mounting panel 9. . The back surface of the bottom portion 51 of the protection member 5 is pressed toward the front surface 91 of the mounting panel 9 by the flange portion 23. The front surface of the bottom portion 51 is pressed by the mounting panel 9 toward the back surface of the flange portion 23 via the washer 61. Thereby, it is possible to prevent (or suppress) the protection member 5 from rotating in the circumferential direction relative to the main body 2.

図4に示すように、底部51の内側面には、径方向内側に突出する2つの凸部54(図4では、一方の凸部54のみを図示する。)が設けられる。2つの凸部54は、周方向において180°ずれた位置に配置される。凸部54の周方向の幅は、本体部2の溝部24(図1参照)の周方向の幅よりも僅かに小さく、凸部54の前後方向の厚さは、本体部2の第1雄ねじ部21におけるねじ山のピッチよりも大きい。2つの凸部54が2つの溝部24内に位置することにより、保護部材5が、本体部2に対して相対的に周方向に回転することを、より一層防止(または、抑制)することができる。   As shown in FIG. 4, two convex portions 54 (only one convex portion 54 is illustrated in FIG. 4) are provided on the inner surface of the bottom portion 51 so as to project radially inward. The two convex portions 54 are arranged at positions shifted by 180 ° in the circumferential direction. The circumferential width of the convex portion 54 is slightly smaller than the circumferential width of the groove portion 24 (see FIG. 1) of the main body 2, and the thickness of the convex portion 54 in the front-rear direction is the first male screw of the main body 2. It is larger than the pitch of the thread in the part 21. By positioning the two convex portions 54 in the two groove portions 24, the protective member 5 can be further prevented (or suppressed) from rotating in the circumferential direction relative to the main body portion 2. it can.

図3に示すように、保護部材5の側壁部52は、底部51の外縁部から、カバー部材4の取付部43の外側面45に沿って前方に広がる。側壁部52の内側面57は、略円筒面状であり、内側に雌ねじ部44が位置する取付部43の外側面45に接する。側壁部52の外側面55は、底部51に近づくに従って外径が漸次増大する傾斜面である。本実施の形態では、側壁部52の外側面55は、円錐台の外側面である。側壁部52の前端は、取付部43の前端と前後方向に関しておよそ同じ位置に位置する。取付部43の外側面45は、全周に亘って保護部材5の側壁部52により覆われる。取付部43は、上述のように、本体部2の前端部と径方向に重なっているため、光源25からの光は取付部43から外部にほとんど出射されない。したがって、カバー部材4からの光の導出は、保護部材5により実質的に妨げられない。   As shown in FIG. 3, the side wall portion 52 of the protection member 5 extends forward from the outer edge portion of the bottom portion 51 along the outer surface 45 of the attachment portion 43 of the cover member 4. The inner side surface 57 of the side wall portion 52 has a substantially cylindrical surface shape, and comes into contact with the outer side surface 45 of the attachment portion 43 where the female screw portion 44 is located inside. The outer surface 55 of the side wall 52 is an inclined surface whose outer diameter gradually increases as it approaches the bottom 51. In the present embodiment, the outer surface 55 of the side wall 52 is the outer surface of the truncated cone. The front end of the side wall portion 52 is located at approximately the same position as the front end of the attachment portion 43 in the front-rear direction. The outer surface 45 of the attachment portion 43 is covered with the side wall portion 52 of the protection member 5 over the entire circumference. As described above, since the attachment portion 43 overlaps the front end portion of the main body portion 2 in the radial direction, light from the light source 25 is hardly emitted from the attachment portion 43 to the outside. Therefore, the lead-out of light from the cover member 4 is not substantially hindered by the protective member 5.

図5は、取付パネル9への取り付け途上の発光装置1の一部を拡大して示す断面図である。図5では、カバー部材4が取り付けられた本体部2が、保護部材5の底部51の開口53に前側から挿入され、さらに、取付パネル9のパネル貫通孔93に前側から挿入された状態を示す。図5に示す状態では、固定部3は本体部2に取り付けられていない。   FIG. 5 is an enlarged cross-sectional view showing a part of the light emitting device 1 in the process of being attached to the attachment panel 9. In FIG. 5, the main body 2 to which the cover member 4 is attached is inserted into the opening 53 of the bottom 51 of the protection member 5 from the front side, and further inserted into the panel through hole 93 of the attachment panel 9 from the front side. . In the state shown in FIG. 5, the fixing portion 3 is not attached to the main body portion 2.

図5に示すように、保護部材5の底部51の背面56は、内周部561と、外周部562とを有する。内周部561は、底部51の内周縁から側壁部52の内側面57の径方向の位置まで、中心軸J1(図3参照)に垂直に広がる略円環面である。外周部562は、内周部561の外周縁から径方向外側に広がり、背面56の外周縁に至る略円環面である。外周部562は、径方向外側に向かうに従って漸次後側に向かう傾斜面である。中心軸J1に垂直な平面に対する外周部562の傾斜はごく僅かである。図5に示す状態では、内周部561は、僅かな間隙を介して取付パネル9の前面91と前後方向にて対向する。また、外周部562は、径方向外側に向かうに従って取付パネル9の前面91に漸次近づき、外周部562の外縁部のみが取付パネル9の前面91に接する。   As shown in FIG. 5, the back surface 56 of the bottom 51 of the protection member 5 has an inner peripheral part 561 and an outer peripheral part 562. The inner peripheral portion 561 is a substantially annular surface that extends perpendicularly to the central axis J <b> 1 (see FIG. 3) from the inner peripheral edge of the bottom portion 51 to the radial position of the inner side surface 57 of the side wall portion 52. The outer peripheral portion 562 is a substantially annular surface that extends radially outward from the outer peripheral edge of the inner peripheral portion 561 and reaches the outer peripheral edge of the back surface 56. The outer peripheral portion 562 is an inclined surface that gradually goes to the rear side as it goes radially outward. The inclination of the outer peripheral portion 562 with respect to the plane perpendicular to the central axis J1 is very slight. In the state shown in FIG. 5, the inner peripheral portion 561 faces the front surface 91 of the mounting panel 9 in the front-rear direction with a slight gap. Further, the outer peripheral portion 562 gradually approaches the front surface 91 of the mounting panel 9 as it goes radially outward, and only the outer edge portion of the outer peripheral portion 562 contacts the front surface 91 of the mounting panel 9.

図5に示す状態では、保護部材5の側壁部52の内側面57は、底部51から離れるに従って漸次径方向外側に向かう傾斜面である。中心軸J1を中心とする円筒面に対する内側面57の傾斜はごく僅かである。側壁部52の内側面57は、僅かな間隙を介してカバー部材4の取付部43の外側面45と径方向にて対向する。   In the state shown in FIG. 5, the inner side surface 57 of the side wall portion 52 of the protection member 5 is an inclined surface that gradually goes outward in the radial direction as the distance from the bottom portion 51 increases. The inclination of the inner surface 57 with respect to the cylindrical surface around the central axis J1 is very slight. The inner side surface 57 of the side wall portion 52 faces the outer side surface 45 of the attachment portion 43 of the cover member 4 in the radial direction with a slight gap therebetween.

発光装置1では、図3に示すように、固定部3が本体部2の第1雄ねじ部21に螺合して取付パネル9の背面92を押圧するまで締められることにより、図5に示す保護部材5の底部51の内縁部(すなわち、内周部561のうち開口53近傍の部位)が、本体部2のフランジ部23により、取付パネル9の前面91に向けて押圧される。底部51の内縁部は、図6に示すように、外周部562の外周縁近傍の部位である外縁部を支点として取付パネル9に向かって撓み、保護部材5の側壁部52は、径方向内側へと撓む(すなわち、弾性変形する。)。換言すれば、底部51の外縁部が、内縁部を支点として前側に撓むことにより、側壁部52が径方向内側へと撓む。これにより、側壁部52の内側面57が、カバー部材4の取付部43の外側面45に接し、取付部43の外側面45が、保護部材5の側壁部52により径方向内側へと押圧される。   In the light emitting device 1, as shown in FIG. 3, the fixing portion 3 is tightened until the fixing portion 3 is screwed into the first male screw portion 21 of the main body portion 2 and presses the back surface 92 of the mounting panel 9. The inner edge portion of the bottom portion 51 of the member 5 (that is, the portion in the vicinity of the opening 53 in the inner peripheral portion 561) is pressed toward the front surface 91 of the mounting panel 9 by the flange portion 23 of the main body portion 2. As shown in FIG. 6, the inner edge portion of the bottom portion 51 is bent toward the mounting panel 9 with the outer edge portion being a portion in the vicinity of the outer peripheral edge of the outer peripheral portion 562 as a fulcrum, and the side wall portion 52 of the protection member 5 is radially inward. (Ie, elastically deformed). In other words, when the outer edge portion of the bottom portion 51 is bent forward with the inner edge portion as a fulcrum, the side wall portion 52 is bent radially inward. As a result, the inner side surface 57 of the side wall portion 52 is in contact with the outer side surface 45 of the mounting portion 43 of the cover member 4, and the outer side surface 45 of the mounting portion 43 is pressed radially inward by the side wall portion 52 of the protection member 5. The

このため、カバー部材4が本体部2から外れる方向にカバー部材4を回転させようとすると、取付部43の外側面45と側壁部52の内側面57との間に摩擦力(すなわち、抵抗)が生じ、カバー部材4の回転が防止される。換言すれば、保護部材5の側壁部52が、カバー部材4の取付部43の外側面45に接し、外側面45を径方向内側へと押圧することにより、第2雄ねじ部22と雌ねじ部44との係合が解除される方向(すなわち、前方)へのカバー部材4の移動が妨げられる。その結果、カバー部材4の意図に反した取り外し(例えば、いたずらによる取り外し)を防止することができる。   For this reason, when the cover member 4 is rotated in a direction in which the cover member 4 is detached from the main body portion 2, a frictional force (that is, resistance) is generated between the outer surface 45 of the attachment portion 43 and the inner surface 57 of the side wall portion 52. And the rotation of the cover member 4 is prevented. In other words, the side wall portion 52 of the protection member 5 is in contact with the outer surface 45 of the mounting portion 43 of the cover member 4 and presses the outer surface 45 radially inward, whereby the second male screw portion 22 and the female screw portion 44. The cover member 4 is prevented from moving in the direction in which the engagement is released (ie, forward). As a result, removal (for example, removal by mischief) contrary to the intention of the cover member 4 can be prevented.

また、発光装置1では、カバー部材4を保護部材5と共に回転させようとしても、保護部材5の底部51が、本体部2のフランジ部23により取付パネル9の前面91に向けて押圧されているため、保護部材5の回転も防止される。その結果、カバー部材4の取り外しをより一層防止することができる。   In the light emitting device 1, even if the cover member 4 is rotated together with the protection member 5, the bottom portion 51 of the protection member 5 is pressed toward the front surface 91 of the mounting panel 9 by the flange portion 23 of the main body portion 2. Therefore, rotation of the protection member 5 is also prevented. As a result, it is possible to further prevent the cover member 4 from being removed.

上述のように、保護部材5の底部51に設けられた2つの凸部54(図4参照)は、本体部2の2つの溝部24内に配置される。これにより、保護部材5が本体部2に対して相対的に回転することが、より一層防止される。その結果、カバー部材4の取り外しをさらに防止することができる。   As described above, the two convex portions 54 (see FIG. 4) provided on the bottom portion 51 of the protection member 5 are disposed in the two groove portions 24 of the main body portion 2. This further prevents the protective member 5 from rotating relative to the main body 2. As a result, it is possible to further prevent the cover member 4 from being removed.

カバー部材4では、取付部43の外側面45のおよそ全体が、保護部材5の側壁部52により覆われている。このため、カバー部材4を把持しようとしても、指先は透光部41の略球面状の滑らかな外側面にて滑り、カバー部材4を強く把持することは難しい。その結果、カバー部材4の取り外しをより一層防止することができる。また、保護部材5の側壁部52の外側面55が、円錐台の滑らかな外側面であるため、保護部材5を強く把持することも困難である。このため、カバー部材4を保護部材5と共に把持し、カバー部材4を回転させるための力を加えることも容易ではない。その結果、カバー部材4の取り外しをさらに防止することができる。   In the cover member 4, substantially the entire outer surface 45 of the attachment portion 43 is covered with the side wall portion 52 of the protection member 5. For this reason, even if it is going to hold | grip the cover member 4, a fingertip will slide on the substantially spherical-shaped smooth outer surface of the translucent part 41, and it is difficult to hold | grip the cover member 4 strongly. As a result, it is possible to further prevent the cover member 4 from being removed. Moreover, since the outer side surface 55 of the side wall part 52 of the protection member 5 is a smooth outer side surface of a truncated cone, it is difficult to firmly hold the protection member 5. For this reason, it is not easy to grip the cover member 4 together with the protection member 5 and apply a force for rotating the cover member 4. As a result, it is possible to further prevent the cover member 4 from being removed.

上述のように、発光装置1が取付パネル9に取り付けられる際には、保護部材5の底部51が取付パネル9の前面91に向かって押圧されて撓み、保護部材5の側壁部52が径方向内側へと撓んで取付部43の外側面45に接する。このため、撓む前の側壁部52の内側面57を、カバー部材4の取付部43の外側面45から離間させておくことが可能となる。これにより、保護部材5の側壁部52の内側に、カバー部材4の取付部43を容易に挿入することができる。なお、保護部材5の側壁部52の内側面57は、底部51が撓む前の状態でカバー部材4の取付部43の外側面45に接していてもよい。この場合、底部51を上述のように撓ませることにより、側壁部52が取付部43を径方向内側に押圧する力を増大させることができる。   As described above, when the light emitting device 1 is attached to the attachment panel 9, the bottom portion 51 of the protection member 5 is pressed and bent toward the front surface 91 of the attachment panel 9, and the side wall portion 52 of the protection member 5 is in the radial direction. It bends inward and contacts the outer surface 45 of the mounting portion 43. For this reason, the inner side surface 57 of the side wall portion 52 before bending can be separated from the outer side surface 45 of the attachment portion 43 of the cover member 4. Thereby, the attachment part 43 of the cover member 4 can be easily inserted inside the side wall part 52 of the protection member 5. The inner side surface 57 of the side wall portion 52 of the protection member 5 may be in contact with the outer side surface 45 of the attachment portion 43 of the cover member 4 before the bottom portion 51 is bent. In this case, by bending the bottom portion 51 as described above, it is possible to increase the force with which the side wall portion 52 presses the attachment portion 43 radially inward.

発光装置1は、鉄道の駅のプラットホーム等のように不特定多数の人が触れることができる場所以外の場所に設置されることもある。例えば、発光装置1は、工場内に設置される装置の側壁等に取り付けられてもよい。この場合、いたずら等によるカバー部材4の取り外しを考慮する必要はなく、発光装置1のメンテナンス性の向上等のために、カバー部材4を取付パネル9の前側から容易に着脱できることが好ましい。   The light emitting device 1 may be installed in a place other than a place where an unspecified number of people can touch, such as a platform of a railway station. For example, the light emitting device 1 may be attached to a side wall or the like of a device installed in a factory. In this case, it is not necessary to consider the removal of the cover member 4 due to mischief or the like, and it is preferable that the cover member 4 can be easily detached from the front side of the mounting panel 9 in order to improve the maintainability of the light emitting device 1.

このように、カバー部材4の容易な着脱が求められる場合には、図7に示すように、本体部2のフランジ部23と取付パネル9との間に保護部材5を挟むことなく、本体部2が取付パネル9に取り付けられる。保護部材5が省略されることにより、カバー部材4の取付部43が径方向内側に向かって押圧されることがないため、カバー部材4を容易に回転させて本体部2から取り外すことができる。   Thus, when the easy attachment / detachment of the cover member 4 is required, as shown in FIG. 7, the main body portion is not sandwiched between the flange portion 23 of the main body portion 2 and the mounting panel 9. 2 is attached to the attachment panel 9. Since the protective member 5 is omitted, the attachment portion 43 of the cover member 4 is not pressed radially inward, so that the cover member 4 can be easily rotated and removed from the main body portion 2.

図8は、第2の実施の形態に係る発光装置1aの一部を拡大して示す断面図である。発光装置1aでは、保護部材5が、穴581および外接部材582を備える。その他の構成は、図1ないし図6に示す発光装置1と同様であり、以下の説明では、対応する構成に同符号を付す。   FIG. 8 is an enlarged sectional view showing a part of the light emitting device 1a according to the second embodiment. In the light emitting device 1a, the protection member 5 includes a hole 581 and a circumscribed member 582. Other configurations are the same as those of the light-emitting device 1 shown in FIGS. 1 to 6, and the same reference numerals are given to the corresponding configurations in the following description.

図8に示す発光装置1aでは、穴581は、保護部材5の底部51の背面56から前側に延びて側壁部52の内側面57に至る。穴581は、側壁部52の前端までは貫通しない。本実施の形態では、4つの穴581が周方向に等角度間隔にて配置される。なお、穴581の周方向における配置は適宜変更されてよい。また、穴581の個数は適宜変更されてよい。   In the light emitting device 1 a shown in FIG. 8, the hole 581 extends from the back surface 56 of the bottom portion 51 of the protective member 5 to the front side and reaches the inner side surface 57 of the side wall portion 52. The hole 581 does not penetrate to the front end of the side wall portion 52. In the present embodiment, four holes 581 are arranged at equiangular intervals in the circumferential direction. The arrangement of the holes 581 in the circumferential direction may be changed as appropriate. Further, the number of holes 581 may be changed as appropriate.

複数の穴581にはそれぞれ、複数の外接部材582が挿入される。外接部材582としては、例えば、後端部(すなわち、取付パネル9に近い方の端部)に六角穴が設けられたねじや、穴581に圧入される略円柱状のピンが利用される。本実施の形態では、外接部材582として、穴581に係合する上述のねじが利用される。外接部材582は、カバー部材4の取付部43が保護部材5の側壁部52の内側に挿入された状態、かつ、本体部2が取付パネル9に取り付けられる前に、穴581に挿入される。外接部材582の一部は、側壁部52の内側面57から露出し、取付部43の外側面45に接する。外接部材582の当該一部(以下、「露出部」という。)は、外接部材582の穴581内における回転に伴って取付部43の外側面45を削り、外側面45に溝を形成する。当該溝と外接部材582の露出部のねじ山とが嵌合することにより、外接部材582がカバー部材4と機械的に係合するとともに、取付部43の外側面45を径方向内側へと押圧する。   A plurality of circumscribed members 582 are inserted into the plurality of holes 581, respectively. As the circumscribed member 582, for example, a screw having a hexagonal hole provided at the rear end portion (that is, an end portion closer to the mounting panel 9) or a substantially cylindrical pin press-fitted into the hole 581 is used. In the present embodiment, the above-described screw that engages with the hole 581 is used as the circumscribed member 582. The circumscribed member 582 is inserted into the hole 581 in a state where the attachment portion 43 of the cover member 4 is inserted inside the side wall portion 52 of the protection member 5 and before the main body portion 2 is attached to the attachment panel 9. A part of the circumscribed member 582 is exposed from the inner side surface 57 of the side wall portion 52 and is in contact with the outer side surface 45 of the attachment portion 43. The part of the circumscribed member 582 (hereinafter referred to as “exposed portion”) scrapes the outer surface 45 of the mounting portion 43 as the circumscribed member 582 rotates in the hole 581 to form a groove in the outer surface 45. By fitting the groove and the thread of the exposed portion of the circumscribed member 582, the circumscribed member 582 is mechanically engaged with the cover member 4, and the outer surface 45 of the mounting portion 43 is pressed radially inward. To do.

発光装置1aでは、図1に示す発光装置1と同様に、保護部材5の側壁部52が、カバー部材4の取付部43の外側面45を径方向内側へと押圧することにより、第2雄ねじ部22と雌ねじ部44との係合が解除される方向へのカバー部材4の移動が妨げられる。その結果、カバー部材4の取り外しを防止することができる。   In the light emitting device 1 a, as in the light emitting device 1 shown in FIG. 1, the side wall portion 52 of the protection member 5 presses the outer surface 45 of the mounting portion 43 of the cover member 4 radially inward, whereby the second male screw The movement of the cover member 4 in the direction in which the engagement between the portion 22 and the female screw portion 44 is released is prevented. As a result, removal of the cover member 4 can be prevented.

発光装置1aでは、特に、カバー部材4の外側面45に接して機械的に係合する外接部材582により、カバー部材4の雌ねじ部44と本体部2の第2雄ねじ部22との係合が解除される方向へのカバー部材4の移動がさらに妨げられる。その結果、カバー部材4の取り外しをより一層防止することができる。   In the light emitting device 1a, in particular, the engagement between the female screw portion 44 of the cover member 4 and the second male screw portion 22 of the main body 2 is performed by the circumscribed member 582 that mechanically engages with the outer surface 45 of the cover member 4. The movement of the cover member 4 in the released direction is further prevented. As a result, it is possible to further prevent the cover member 4 from being removed.

図9は、第3の実施の形態に係る発光装置1bの一部を拡大して示す断面図である。発光装置1bでは、本体部2の第2雄ねじ部22近傍の部位の形状、および、カバー部材4の取付部43の形状が、図1ないし図6に示す発光装置1と異なる。また、発光装置1bでは、本体部2にフランジ部23(図3参照)が設けられない。その他の構成は、図1ないし図6に示す発光装置1と同様であり、以下の説明では、対応する構成に同符号を付す。   FIG. 9 is an enlarged cross-sectional view showing a part of the light emitting device 1b according to the third embodiment. The light emitting device 1b is different from the light emitting device 1 shown in FIGS. 1 to 6 in the shape of the portion in the vicinity of the second male screw portion 22 of the main body 2 and the shape of the mounting portion 43 of the cover member 4. In the light emitting device 1b, the main body 2 is not provided with the flange 23 (see FIG. 3). Other configurations are the same as those of the light-emitting device 1 shown in FIGS. 1 to 6, and the same reference numerals are given to the corresponding configurations in the following description.

図9に示す発光装置1bでは、カバー部材4の取付部43の後端部46(すなわち、図9中の下側の端部)が、ワッシャ61を介して、保護部材5の底部51の前面に間接的に接する。保護部材5の底部51は、カバー部材4の後端部46と取付パネル9の前面91との間に挟まれる。発光装置1bでは、固定部3が締められて、底部51がカバー部材4と取付パネル9とに挟まれることにより、保護部材5が、本体部2および取付パネル9に対して固定される。これにより、保護部材5が、本体部2に対して相対的に周方向に回転することを防止(または、抑制)することができる。   In the light emitting device 1 b shown in FIG. 9, the rear end portion 46 (that is, the lower end portion in FIG. 9) of the attachment portion 43 of the cover member 4 is connected to the front surface of the bottom portion 51 of the protection member 5 via the washer 61. Contact indirectly. The bottom 51 of the protection member 5 is sandwiched between the rear end portion 46 of the cover member 4 and the front surface 91 of the mounting panel 9. In the light emitting device 1 b, the fixing member 3 is tightened and the bottom 51 is sandwiched between the cover member 4 and the mounting panel 9, whereby the protection member 5 is fixed to the main body 2 and the mounting panel 9. Thereby, it is possible to prevent (or suppress) the protection member 5 from rotating in the circumferential direction relative to the main body 2.

発光装置1bでは、図1に示す発光装置1と同様に、保護部材5の側壁部52が、カバー部材4の取付部43の外側面45を径方向内側へと押圧することにより、第2雄ねじ部22と雌ねじ部44との係合が解除される方向へのカバー部材4の移動が妨げられる。その結果、カバー部材4の取り外しを防止することができる。また、カバー部材4を保護部材5と共に回転させようとしても、保護部材5の底部51が、カバー部材4により取付パネル9の前面91に向けて押圧されているため、保護部材5の回転も防止される。その結果、カバー部材4の取り外しをより一層防止することができる。   In the light emitting device 1 b, as in the light emitting device 1 shown in FIG. 1, the side wall portion 52 of the protection member 5 presses the outer surface 45 of the mounting portion 43 of the cover member 4 inward in the radial direction. The movement of the cover member 4 in the direction in which the engagement between the portion 22 and the female screw portion 44 is released is prevented. As a result, removal of the cover member 4 can be prevented. Even when the cover member 4 is rotated together with the protection member 5, the bottom 51 of the protection member 5 is pressed toward the front surface 91 of the mounting panel 9 by the cover member 4, and thus the rotation of the protection member 5 is prevented. Is done. As a result, it is possible to further prevent the cover member 4 from being removed.

図10は、本発明の第4の実施の形態に係る発光装置1cの正面図であり、図11は、発光装置1cを図10のB−Bの位置にて切断した断面図である。発光装置1cは、略四角柱状の本体部2aと、略矩形環状の固定部3aと、正面視において略矩形のカバー部材4aと、正面視において略矩形の保護部材5aとを備える。図11に示すように、本体部2aは、取付パネル9の略矩形のパネル貫通孔93aに挿入される。取付パネル9の後側において、固定部3aが本体部2aに締まり嵌めにて嵌合されることにより、本体部2aが取付パネル9に固定される。本体部2aの内部には、第1の実施の形態と同様に、LED素子やLED電球等の光源が設けられる。   FIG. 10 is a front view of a light emitting device 1c according to the fourth embodiment of the present invention, and FIG. 11 is a cross-sectional view of the light emitting device 1c cut at a position BB in FIG. The light emitting device 1c includes a substantially quadrangular columnar main body 2a, a substantially rectangular annular fixing portion 3a, a substantially rectangular cover member 4a in a front view, and a substantially rectangular protective member 5a in a front view. As shown in FIG. 11, the main body 2 a is inserted into a substantially rectangular panel through hole 93 a of the mounting panel 9. On the rear side of the mounting panel 9, the main body 2 a is fixed to the mounting panel 9 by fitting the fixing portion 3 a to the main body 2 a by an interference fit. As in the first embodiment, a light source such as an LED element or an LED bulb is provided inside the main body 2a.

本体部2aの前部201は、取付パネル9の前側にて、パネル貫通孔93aよりも外側に広がる略矩形環板状のフランジ部23と、フランジ部23の外縁部から前方に広がる略矩形筒状の筒部26とを備える。以下の説明では、筒部26の図10中における左右両側の一対の部位(すなわち、正面視における左右両側の一対の辺に対応する部位)を「第1側壁部261」と呼び、図10中における上下の一対の部位を「第2側壁部262」という。図11では、筒部26の第1側壁部261が図示されている。第1側壁部261の前端部には、第1側壁部261の全長(図10中における上下方向の全長)に亘って内側に突出する係合爪である第1係合部22aが設けられる。第2側壁部262には、係合爪は設けられない。   The front part 201 of the main body part 2a is a substantially rectangular annular plate-shaped flange part 23 that spreads outside the panel through-hole 93a on the front side of the mounting panel 9, and a substantially rectangular cylinder that spreads forward from the outer edge part of the flange part 23. A cylindrical portion 26 is provided. In the following description, a pair of portions on the left and right sides in FIG. 10 of the cylindrical portion 26 (that is, portions corresponding to a pair of sides on the left and right sides in the front view) are referred to as “first side wall portions 261”. The pair of upper and lower parts in FIG. In FIG. 11, the first side wall portion 261 of the cylindrical portion 26 is illustrated. The front end portion of the first side wall portion 261 is provided with a first engaging portion 22a that is an engaging claw that protrudes inward over the entire length of the first side wall portion 261 (the total length in the vertical direction in FIG. 10). The second side wall portion 262 is not provided with an engaging claw.

カバー部材4aは、略矩形板状の透光部41と、透光部41の外縁部から後方へと広がる略矩形筒状の取付部43とを備える。取付部43は、本体部2aの筒部26の内側に挿入される。以下の説明では、取付部43の4つの側壁部のうち、筒部26の第1側壁部261に対向する側壁部を「第1側壁部431」と呼び、筒部26の第2側壁部262に対向する側壁部を「第2側壁部」と呼ぶ。図11では、取付部43の第1側壁部431が図示されている。取付部43の第1側壁部431の後端部には、第1側壁部431の全長(図10中における上下方向の全長)に亘って外側に突出する係合爪である第2係合部44aが設けられる。取付部43の第2側壁部には、係合爪は設けられない。   The cover member 4a includes a substantially rectangular plate-shaped light transmitting portion 41 and a substantially rectangular cylindrical mounting portion 43 that extends rearward from the outer edge portion of the light transmitting portion 41. The attachment part 43 is inserted inside the cylinder part 26 of the main body part 2a. In the following description, of the four side wall portions of the attachment portion 43, the side wall portion facing the first side wall portion 261 of the cylinder portion 26 is referred to as “first side wall portion 431” and the second side wall portion 262 of the cylinder portion 26. The side wall portion that faces is called the “second side wall portion”. In FIG. 11, the first side wall portion 431 of the attachment portion 43 is illustrated. At the rear end portion of the first side wall portion 431 of the mounting portion 43, a second engaging portion is an engaging claw that protrudes outward over the entire length of the first side wall portion 431 (the total length in the vertical direction in FIG. 10). 44a is provided. An engagement claw is not provided on the second side wall portion of the attachment portion 43.

カバー部材4aが本体部2aに取り付けられる際には、第1側壁部431を内側に撓ませつつ、取付部43が筒部26の内側に挿入される。そして、第1側壁部431の撓みが解消されて元の形状に戻ることにより、カバー部材4aの第2係合部44aが、本体部2aの第1係合部22aの下方に位置する。第1係合部22aと第2係合部44aとが係合することにより、カバー部材4aが本体部2aに着脱可能に取り付けられる。カバー部材4aは、いわゆるパッチン止め(スナップフィット)にて本体部2aに取り付けられ、本体部2aの内部を前側から覆う。   When the cover member 4a is attached to the main body portion 2a, the attachment portion 43 is inserted inside the cylindrical portion 26 while the first side wall portion 431 is bent inward. And the 2nd engaging part 44a of the cover member 4a is located under the 1st engaging part 22a of the main-body part 2a by canceling the bending of the 1st side wall part 431, and returning to an original shape. When the first engaging portion 22a and the second engaging portion 44a are engaged, the cover member 4a is detachably attached to the main body portion 2a. The cover member 4a is attached to the main body 2a by so-called patching (snap fit), and covers the inside of the main body 2a from the front side.

図12は、保護部材5aを示す斜視図である。図11および図12に示すように、保護部材5aは、底部51と、側壁部52とを備える。底部51は、本体部2aが挿入される略矩形の開口53を有する略矩形環板状である。図11に示すように、底部51は、本体部2aのフランジ部23の背面と取付パネル9の前面91との間に挟まれる。底部51の前面および背面は、取付パネル9の前面91に略平行である。底部51の前面は、ワッシャ61を介して、フランジ部23の背面に間接的に接する。底部51の背面は、取付パネル9の前面91に直接的に接する。   FIG. 12 is a perspective view showing the protection member 5a. As shown in FIGS. 11 and 12, the protection member 5 a includes a bottom 51 and a side wall 52. The bottom 51 has a substantially rectangular annular plate shape having a substantially rectangular opening 53 into which the main body 2a is inserted. As shown in FIG. 11, the bottom 51 is sandwiched between the back surface of the flange portion 23 of the main body portion 2 a and the front surface 91 of the mounting panel 9. The front surface and the back surface of the bottom portion 51 are substantially parallel to the front surface 91 of the mounting panel 9. The front surface of the bottom portion 51 indirectly contacts the back surface of the flange portion 23 via the washer 61. The back surface of the bottom portion 51 is in direct contact with the front surface 91 of the mounting panel 9.

発光装置1cでは、底部51がフランジ部23と取付パネル9とに挟まれることにより、保護部材5aが取付パネル9に固定される。保護部材5aの底部51の背面は、フランジ部23により取付パネル9の前面91に向けて押圧される。底部51の前面は、取付パネル9により、ワッシャ61を介してフランジ部23の背面に向けて押圧される。   In the light emitting device 1 c, the protection member 5 a is fixed to the mounting panel 9 by sandwiching the bottom 51 between the flange portion 23 and the mounting panel 9. The back surface of the bottom portion 51 of the protection member 5 a is pressed toward the front surface 91 of the mounting panel 9 by the flange portion 23. The front surface of the bottom portion 51 is pressed by the mounting panel 9 toward the back surface of the flange portion 23 via the washer 61.

保護部材5aの側壁部52は、略矩形の底部51の外縁部のうち、本体部2aの筒部26の第1側壁部261およびカバー部材4aの第1側壁部431に対応する一対の辺から、筒部26の第1側壁部261に沿って前方に広がる。側壁部52の内側面は、第1側壁部261の外側面から離間している。側壁部52の外側面55は、底部51に近づくに従って第1側壁部261から漸次離れる傾斜面である。側壁部52の前端は、第1側壁部261の前端よりも前側に位置する。側壁部52の前端部521は、第1側壁部261の前端よりも前方において、カバー部材4aの第1側壁部431に向かって内側へと湾曲する。側壁部52の前端部521の内側面522は、カバー部材4aの第1側壁部431の外側面433に接する。   The side wall part 52 of the protection member 5a is formed from a pair of sides corresponding to the first side wall part 261 of the cylindrical part 26 of the main body part 2a and the first side wall part 431 of the cover member 4a among the outer edge part of the substantially rectangular bottom part 51. Further, it spreads forward along the first side wall portion 261 of the cylindrical portion 26. The inner surface of the side wall 52 is separated from the outer surface of the first side wall 261. The outer side surface 55 of the side wall portion 52 is an inclined surface that gradually separates from the first side wall portion 261 as it approaches the bottom portion 51. The front end of the side wall portion 52 is located on the front side of the front end of the first side wall portion 261. The front end 521 of the side wall 52 is curved inward toward the first side wall 431 of the cover member 4a in front of the front end of the first side wall 261. The inner surface 522 of the front end 521 of the side wall 52 is in contact with the outer surface 433 of the first side wall 431 of the cover member 4a.

図13は、取付パネル9への取り付け途上の発光装置1cの一部を拡大して示す断面図である。図13では、カバー部材4aが取り付けられた本体部2aが、保護部材5aの底部51の開口53に前側から挿入され、さらに、取付パネル9のパネル貫通孔93aに前側から挿入された状態を示す。図13に示す状態では、固定部3aは本体部2aに取り付けられていない。   FIG. 13 is an enlarged cross-sectional view of a part of the light emitting device 1 c that is being attached to the attachment panel 9. In FIG. 13, the main body 2a to which the cover member 4a is attached is inserted from the front side into the opening 53 of the bottom 51 of the protection member 5a, and further inserted into the panel through hole 93a of the attachment panel 9 from the front side. . In the state shown in FIG. 13, the fixing portion 3a is not attached to the main body portion 2a.

図13に示すように、保護部材5aの底部51の背面56は、内側部563と、外側部564とを有する。内側部563は、開口53から取付パネル9の前面91に略平行に広がり、外側部564は、内側部563の外縁から開口53から離れる方向に広がる。外側部564は、開口53から離れるに従って漸次後側に向かう傾斜面である。取付パネル9の前面91に対する外側部564の傾斜はごく僅かである。図13に示す状態では、内側部563は、僅かな間隙を介して取付パネル9の前面91と前後方向にて対向する。また、外側部564は、開口53から離れるに従って取付パネル9の前面91に漸次近づき、外側部564の外縁部のみが取付パネル9の前面91に接する。   As shown in FIG. 13, the back surface 56 of the bottom 51 of the protection member 5 a has an inner part 563 and an outer part 564. The inner portion 563 extends from the opening 53 substantially parallel to the front surface 91 of the mounting panel 9, and the outer portion 564 extends from the outer edge of the inner portion 563 in a direction away from the opening 53. The outer portion 564 is an inclined surface that gradually goes to the rear side as the distance from the opening 53 increases. The inclination of the outer portion 564 with respect to the front surface 91 of the mounting panel 9 is very slight. In the state shown in FIG. 13, the inner portion 563 faces the front surface 91 of the mounting panel 9 in the front-rear direction with a slight gap. Further, the outer portion 564 gradually approaches the front surface 91 of the mounting panel 9 as the distance from the opening 53 increases, and only the outer edge portion of the outer portion 564 contacts the front surface 91 of the mounting panel 9.

保護部材5aの前端部521の内側面522は、前方に向かうに従って開口53から漸次離れる傾斜面である。内側面522の傾斜はごく僅かである。図13に示す状態では、前端部521の内側面522は、僅かな間隙を介してカバー部材4aの第1側壁部431の外側面433と径方向にて対向する。   The inner side surface 522 of the front end 521 of the protection member 5a is an inclined surface that gradually separates from the opening 53 as it goes forward. The inclination of the inner surface 522 is negligible. In the state shown in FIG. 13, the inner side surface 522 of the front end portion 521 is opposed to the outer side surface 433 of the first side wall portion 431 of the cover member 4a through a slight gap in the radial direction.

発光装置1cでは、固定部3a(図11参照)が本体部2aに嵌合して取付パネル9の背面92を押圧することにより、図13に示す保護部材5aの底部51の内縁部(すなわち、内側部563のうち開口53近傍の部位)が、本体部2aのフランジ部23により、取付パネル9の前面91に向けて押圧される。底部51の内縁部は、図11に示すように、外側部564の外縁近傍の部位である外縁部を支点として取付パネル9に向かって撓み、保護部材5aの側壁部52は、本体部2aの第1側壁部261およびカバー部材4aの第1側壁部431に向かって撓む(すなわち、弾性変形する。)。換言すれば、底部51の外縁部が、内縁部を支点として前側に撓むことにより、側壁部52が本体部2aおよびカバー部材4aに向かって撓む。これにより、一対の側壁部52の前端部521の内側面522が、カバー部材4aの一対の第1側壁部431の外側面433に接し、各第1側壁部431の外側面433が、保護部材5aの側壁部52により内側へと(すなわち、他方の第1側壁部431に向かって)押圧される。側壁部52の内側面522の一部は、透光部41の側方にて第1側壁部431の外側面433に接し、内側面522の他の一部は、透光部41よりも後側にて第1側壁部431の外側面433に接する。   In the light emitting device 1c, the fixing portion 3a (see FIG. 11) is fitted to the main body portion 2a and presses the back surface 92 of the mounting panel 9, whereby the inner edge portion of the bottom portion 51 of the protection member 5a shown in FIG. A portion of the inner portion 563 near the opening 53) is pressed toward the front face 91 of the mounting panel 9 by the flange portion 23 of the main body portion 2a. As shown in FIG. 11, the inner edge portion of the bottom portion 51 bends toward the mounting panel 9 with the outer edge portion that is a portion in the vicinity of the outer edge of the outer portion 564 as a fulcrum, and the side wall portion 52 of the protection member 5a The first side wall portion 261 and the first side wall portion 431 of the cover member 4a are bent (that is, elastically deformed). In other words, the outer edge of the bottom 51 is bent forward with the inner edge as a fulcrum, so that the side wall 52 is bent toward the main body 2a and the cover member 4a. Accordingly, the inner side surfaces 522 of the front end portions 521 of the pair of side wall portions 52 are in contact with the outer side surfaces 433 of the pair of first side wall portions 431 of the cover member 4a, and the outer side surfaces 433 of the respective first side wall portions 431 are protected members. 5a is pressed inwardly (that is, toward the other first side wall 431). A part of the inner side surface 522 of the side wall part 52 is in contact with the outer side surface 433 of the first side wall part 431 on the side of the light transmitting part 41, and another part of the inner side surface 522 is behind the light transmitting part 41. It contacts the outer surface 433 of the first side wall portion 431 on the side.

発光装置1cでは、保護部材5aの側壁部52がカバー部材4aの外側面433を内側へと押圧することにより、カバー部材4aを前方に移動させようとすると、側壁部52の内側面522と第1側壁部431の外側面433との間に摩擦力が生じる。これにより、本体部2aの第1係合部22aとカバー部材4aの第2係合部44aとの係合が解除される方向(すなわち、前方)へのカバー部材4aの移動が妨げられる。その結果、カバー部材4aの取り外しを防止することができる。   In the light emitting device 1c, when the side wall portion 52 of the protection member 5a presses the outer surface 433 of the cover member 4a inward to move the cover member 4a forward, the inner surface 522 of the side wall portion 52 and the A frictional force is generated between the outer side surface 433 of the one side wall portion 431. Accordingly, the movement of the cover member 4a in the direction in which the engagement between the first engagement portion 22a of the main body 2a and the second engagement portion 44a of the cover member 4a is released (ie, forward) is prevented. As a result, it is possible to prevent the cover member 4a from being removed.

上述のように、発光装置1cが取付パネル9に取り付けられる際には、保護部材5aの底部51が取付パネル9の前面91に向かって押圧されて撓み、保護部材5aの側壁部52が内側へと撓んで取付部43の第1側壁部431の外側面433に接する。このため、撓む前の一対の側壁部52の前端部521間の距離を大きくすることができる。これにより、一対の側壁部52の間に、本体部2aの筒部26およびカバー部材4aの取付部43を容易に挿入することができる。なお、側壁部52の前端部521の内側面522は、底部51が撓む前の状態でカバー部材4aの第1側壁部431の外側面433に接していてもよい。この場合、底部51を上述のように撓ませることにより、側壁部52が第1側壁部431を内側に押圧する力を増大させることができる。   As described above, when the light emitting device 1c is attached to the attachment panel 9, the bottom 51 of the protection member 5a is pressed and bent toward the front surface 91 of the attachment panel 9, and the side wall 52 of the protection member 5a is inward. And is in contact with the outer side surface 433 of the first side wall portion 431 of the mounting portion 43. For this reason, the distance between the front-end parts 521 of a pair of side wall part 52 before bending can be enlarged. Thereby, the cylindrical part 26 of the main-body part 2a and the attachment part 43 of the cover member 4a can be easily inserted between the pair of side wall parts 52. The inner surface 522 of the front end 521 of the side wall 52 may be in contact with the outer surface 433 of the first side wall 431 of the cover member 4a before the bottom 51 is bent. In this case, by bending the bottom portion 51 as described above, the force with which the side wall portion 52 presses the first side wall portion 431 inward can be increased.

発光装置1cでは、図14に示すように、カバー部材4aの第1側壁部431の外側面433に凹部434が設けられ、保護部材5aの側壁部52において、前端部521の内側面522に、凹部434と嵌合する凸部523が設けられてもよい。凸部523が凹部434に嵌合することにより、本体部2aの第1係合部22aとカバー部材4aの第2係合部44aとの係合が解除される方向へのカバー部材4aの移動がさらに妨げられる。その結果、カバー部材4aの取り外しをより一層防止することができる。なお、保護部材5aの前端部521の内側面522に凹部が設けられ、カバー部材4aの第1側壁部431の外側面433に当該凹部と嵌合する凸部が設けられてもよい。   In the light emitting device 1c, as shown in FIG. 14, a concave portion 434 is provided on the outer side surface 433 of the first side wall portion 431 of the cover member 4a, and on the inner side surface 522 of the front end portion 521 in the side wall portion 52 of the protection member 5a, A convex portion 523 that fits into the concave portion 434 may be provided. By fitting the convex portion 523 into the concave portion 434, the cover member 4a moves in a direction in which the engagement between the first engaging portion 22a of the main body portion 2a and the second engaging portion 44a of the cover member 4a is released. Is further hindered. As a result, it is possible to further prevent the cover member 4a from being removed. In addition, a recessed part may be provided in the inner surface 522 of the front-end part 521 of the protection member 5a, and the convex part fitted to the said recessed part may be provided in the outer surface 433 of the 1st side wall part 431 of the cover member 4a.

図15は、本発明の第5の実施の形態に係る発光装置1dの断面図である。発光装置1dは、中心軸J1を中心とする略円柱状の本体部2bと、正面視において略円形のカバー部材4bと、正面視において略円環状の保護部材5bとを備える。本体部2bの前部201は、取付パネル9の後側から略円形のパネル貫通孔93に挿入される。   FIG. 15 is a sectional view of a light emitting device 1d according to the fifth embodiment of the present invention. The light emitting device 1d includes a substantially cylindrical main body 2b centered on the central axis J1, a cover member 4b having a substantially circular shape when viewed from the front, and a substantially annular protective member 5b when viewed from the front. The front part 201 of the main body 2b is inserted into the substantially circular panel through-hole 93 from the rear side of the mounting panel 9.

本体部2bの前部201の外側面には、第1雄ねじ部21が設けられる。第1雄ねじ部21は、取付パネル9よりも前側から後側まで連続して設けられる。取付パネル9の後側では、略円環状の調整部62が第1雄ねじ部21に螺合する。調整部62の前面には略円環板状のパッキン63が固定されており、パッキン63は取付パネル9の背面92に接する。調整部62の本体部2bに対する前後方向の相対位置を変更することにより、取付パネル9の厚さが変更された場合であっても、本体部2bの取付パネル9から前方への突出長を所望の値に維持することができる。   A first male screw portion 21 is provided on the outer surface of the front portion 201 of the main body portion 2b. The first male screw portion 21 is provided continuously from the front side to the rear side of the mounting panel 9. On the rear side of the mounting panel 9, a substantially annular adjustment portion 62 is screwed into the first male screw portion 21. A substantially annular plate-shaped packing 63 is fixed to the front surface of the adjustment portion 62, and the packing 63 contacts the back surface 92 of the mounting panel 9. Even if the thickness of the attachment panel 9 is changed by changing the relative position of the adjustment portion 62 in the front-rear direction with respect to the main body portion 2b, the projection length of the main body portion 2b forward from the attachment panel 9 is desired. Value can be maintained.

本体部2bの前部201の外側面には、第1雄ねじ部21よりも前方に位置する第2雄ねじ部22が設けられる。第2雄ねじ部22は、第1雄ねじ部21よりも径方向内側に位置する。本体部2bの内部には、LED素子やLED電球等の光源25が設けられる。   A second male screw portion 22 positioned in front of the first male screw portion 21 is provided on the outer surface of the front portion 201 of the main body portion 2b. The second male screw portion 22 is located on the radially inner side than the first male screw portion 21. A light source 25 such as an LED element or an LED bulb is provided inside the main body 2b.

カバー部材4bは、略円板状の透光部41と、透光部41の外縁部から後側へと(すなわち、取付パネル9に向かって)広がる略円筒状の取付部43とを備える。取付部43の内側面には雌ねじ部44が設けられる。第1係合部である本体部2bの第2雄ねじ部22と、第2係合部であるカバー部材4bの雌ねじ部44とが係合(すなわち、螺合)することにより、カバー部材4bが、取付パネル9の前側にて本体部2bの前部201に取り付けられ、本体部2bの内部を前側から覆う。取付部43の外径は、本体部2bの第1雄ねじ部21が設けられる部位の外径よりも僅かに小さい。   The cover member 4 b includes a substantially disc-shaped light transmitting portion 41 and a substantially cylindrical mounting portion 43 that spreads from the outer edge portion of the light transmitting portion 41 to the rear side (that is, toward the mounting panel 9). A female screw portion 44 is provided on the inner side surface of the attachment portion 43. When the second male screw portion 22 of the main body portion 2b as the first engaging portion and the female screw portion 44 of the cover member 4b as the second engaging portion are engaged (that is, screwed), the cover member 4b is It is attached to the front part 201 of the main body part 2b on the front side of the mounting panel 9, and covers the inside of the main body part 2b from the front side. The outer diameter of the attachment portion 43 is slightly smaller than the outer diameter of the portion where the first male screw portion 21 of the main body portion 2b is provided.

図16は、保護部材5bを示す斜視図である。図15および図16に示すように、保護部材5bは、円錐台の中央から当該円錐台の上面よりも小さい直径を有する円柱を除去した形状である。保護部材5bの略円環面状の背面は、取付パネル9の前面91に直接的に接する。保護部材5bの内側面57は、略円筒面状であり、保護部材5bの外側面55は、取付パネル9に近づくに従って外径が漸次増大する傾斜面である。   FIG. 16 is a perspective view showing the protection member 5b. As shown in FIGS. 15 and 16, the protection member 5 b has a shape in which a column having a smaller diameter than the upper surface of the truncated cone is removed from the center of the truncated cone. The substantially ring-shaped back surface of the protection member 5 b is in direct contact with the front surface 91 of the mounting panel 9. The inner surface 57 of the protection member 5b is substantially cylindrical, and the outer surface 55 of the protection member 5b is an inclined surface whose outer diameter gradually increases as it approaches the mounting panel 9.

保護部材5bの内側面57の後部(すなわち、取付パネル9に近い部位)には、雌ねじ部59が設けられる。保護部材5bの雌ねじ部59が、取付パネル9の前側にて本体部2bの第1雄ねじ部21に螺合することにより、保護部材5bが本体部2bに取り付けられる。そして、保護部材5bが、調整部62との間で取付パネル9を挟み、取付パネル9の前面91に接するまで締められることにより、本体部2bが取付パネル9に固定される。   A female screw part 59 is provided at the rear part of the inner side surface 57 of the protective member 5b (that is, the part close to the mounting panel 9). The protective member 5b is attached to the main body portion 2b by the female screw portion 59 of the protective member 5b being screwed into the first male screw portion 21 of the main body portion 2b on the front side of the mounting panel 9. The main body 2b is fixed to the mounting panel 9 by tightening the protective member 5b until the mounting panel 9 is sandwiched between the protective member 5b and the front surface 91 of the mounting panel 9.

保護部材5bの内側面57の前部は、内側に雌ねじ部44が位置する取付部43の外側面45に接する。取付部43の外側面45は、全周に亘って保護部材5bにより覆われる。取付部43は、本体部2の前端部と径方向に重なっているため、光源25からの光は取付部43から外部にほとんど出射されない。したがって、カバー部材4bからの光の導出は、保護部材5bにより実質的に妨げられない。   The front portion of the inner side surface 57 of the protection member 5b is in contact with the outer side surface 45 of the attachment portion 43 where the female screw portion 44 is located inside. The outer surface 45 of the mounting portion 43 is covered with the protective member 5b over the entire circumference. Since the attachment portion 43 overlaps the front end portion of the main body portion 2 in the radial direction, almost no light from the light source 25 is emitted from the attachment portion 43 to the outside. Therefore, the derivation of light from the cover member 4b is not substantially hindered by the protective member 5b.

図17は、取付パネル9への取り付け途上の発光装置1dの一部を拡大して示す断面図である。図17では、カバー部材4bが取り付けられた本体部2bが、取付パネル9のパネル貫通孔93および保護部材5bに後側から挿入され、保護部材5bの雌ねじ部59が本体部2bの第1雄ねじ部21に途中まで螺合した状態を示す。   FIG. 17 is an enlarged cross-sectional view showing a part of the light emitting device 1 d that is being attached to the attachment panel 9. In FIG. 17, the main body 2b to which the cover member 4b is attached is inserted into the panel through-hole 93 and the protective member 5b of the attachment panel 9 from the rear side, and the female screw portion 59 of the protective member 5b is the first male screw of the main body 2b. The state which screwed in part 21 partway is shown.

図17に示すように、保護部材5bの背面56は、内周部561と、外周部562とを有する。内周部561は、背面56の内周縁から中心軸J1に垂直に径方向外側に広がる略円環面である。外周部562は、内周部561の外周縁から径方向外側に広がり、背面56の外周縁に至る略円環面である。外周部562は、径方向外側に向かうに従って漸次後側に向かう傾斜面である。中心軸J1(図15参照)に垂直な平面に対する外周部562の傾斜はごく僅かである。図17に示す状態では、内周部561は、僅かな間隙を介して取付パネル9の前面91と前後方向にて対向する。また、外周部562は、径方向外側に向かうに従って取付パネル9の前面91に漸次近づき、外周部562の外縁部のみが取付パネル9の前面91に接する。   As shown in FIG. 17, the back surface 56 of the protection member 5 b has an inner peripheral portion 561 and an outer peripheral portion 562. The inner peripheral portion 561 is a substantially annular surface that extends radially outward from the inner peripheral edge of the back surface 56 perpendicular to the central axis J1. The outer peripheral portion 562 is a substantially annular surface that extends radially outward from the outer peripheral edge of the inner peripheral portion 561 and reaches the outer peripheral edge of the back surface 56. The outer peripheral portion 562 is an inclined surface that gradually goes to the rear side as it goes radially outward. The inclination of the outer peripheral portion 562 with respect to a plane perpendicular to the central axis J1 (see FIG. 15) is very slight. In the state shown in FIG. 17, the inner peripheral portion 561 faces the front surface 91 of the mounting panel 9 in the front-rear direction with a slight gap. Further, the outer peripheral portion 562 gradually approaches the front surface 91 of the mounting panel 9 as it goes radially outward, and only the outer edge portion of the outer peripheral portion 562 contacts the front surface 91 of the mounting panel 9.

図17に示す状態では、保護部材5bの内側面57は、背面56から離れるに従って漸次径方向外側に向かう傾斜面である。中心軸J1を中心とする円筒面に対する内側面57の傾斜はごく僅かである。保護部材5bの内側面57は、僅かな間隙を介してカバー部材4bの取付部43の外側面45と径方向にて対向する。   In the state shown in FIG. 17, the inner side surface 57 of the protection member 5 b is an inclined surface that gradually goes outward in the radial direction as the distance from the back surface 56 increases. The inclination of the inner surface 57 with respect to the cylindrical surface around the central axis J1 is very slight. The inner surface 57 of the protection member 5b faces the outer surface 45 of the attachment portion 43 of the cover member 4b in a radial direction with a slight gap.

発光装置1dでは、保護部材5bの背面56が、図15に示すように、およそ全面に亘って取付パネル9の前面91に接するまで保護部材5bが締められる。これにより、図17に示す保護部材5bの背面56の外縁部が、取付パネル9の前面91により前方に押圧されて前側に撓む(すなわち、弾性変形する。)。その結果、図15に示すように、保護部材5bの内側面57が、径方向内側へと撓んでカバー部材4bの取付部43の外側面45に接し、取付部43の外側面45が保護部材5bにより径方向内側へと押圧される。   In the light emitting device 1d, the protection member 5b is tightened until the back surface 56 of the protection member 5b is in contact with the front surface 91 of the mounting panel 9 over the entire surface as shown in FIG. Accordingly, the outer edge portion of the back surface 56 of the protection member 5b shown in FIG. 17 is pressed forward by the front surface 91 of the mounting panel 9 and bent forward (that is, elastically deformed). As a result, as shown in FIG. 15, the inner side surface 57 of the protection member 5b bends inward in the radial direction and contacts the outer side surface 45 of the attachment portion 43 of the cover member 4b, and the outer side surface 45 of the attachment portion 43 is the protection member. It is pressed radially inward by 5b.

このため、カバー部材4bが本体部2bから外れる方向にカバー部材4bを回転させようとすると、取付部43の外側面45と保護部材5bの内側面57との間に摩擦力が生じ、カバー部材4bの回転が防止される。換言すれば、保護部材5bが、カバー部材4bの取付部43の外側面45に接し、外側面45を径方向内側へと押圧することにより、第2雄ねじ部22と雌ねじ部44との係合が解除される方向(すなわち、前方)へのカバー部材4bの移動が妨げられる。その結果、カバー部材4bの取り外しを防止することができる。   Therefore, when the cover member 4b is rotated in a direction in which the cover member 4b is detached from the main body portion 2b, a frictional force is generated between the outer side surface 45 of the attachment portion 43 and the inner side surface 57 of the protection member 5b, and the cover member The rotation of 4b is prevented. In other words, the protective member 5b is in contact with the outer surface 45 of the mounting portion 43 of the cover member 4b and presses the outer surface 45 inward in the radial direction, thereby engaging the second male screw portion 22 and the female screw portion 44. The movement of the cover member 4b in the direction in which the is released (that is, the front) is prevented. As a result, it is possible to prevent the cover member 4b from being removed.

上述のように、発光装置1dが取付パネル9に取り付けられる際には、保護部材5bが取付パネル9の前面91に向かって押圧されて撓み、保護部材5bの内側面57が径方向内側へと撓んで取付部43の外側面45に接する。このため、撓む前の保護部材5bの内側面57を、カバー部材4bの取付部43の外側面45から離間させておくことが可能となる。これにより、保護部材5bの内側に、カバー部材4bの取付部43を容易に挿入することができる。なお、保護部材5bの内側面57は、保護部材5bが撓む前の状態でカバー部材4bの取付部43の外側面45に接していてもよい。この場合、保護部材5bを上述のように撓ませることにより、保護部材5bが取付部43を径方向内側に押圧する力を増大させることができる。   As described above, when the light emitting device 1d is attached to the attachment panel 9, the protection member 5b is pressed and bent toward the front surface 91 of the attachment panel 9, and the inner side surface 57 of the protection member 5b is radially inward. It bends and contacts the outer surface 45 of the mounting portion 43. For this reason, the inner surface 57 of the protection member 5b before bending can be separated from the outer surface 45 of the attachment portion 43 of the cover member 4b. Thereby, the attachment part 43 of the cover member 4b can be easily inserted inside the protection member 5b. In addition, the inner surface 57 of the protection member 5b may be in contact with the outer surface 45 of the attachment portion 43 of the cover member 4b in a state before the protection member 5b is bent. In this case, by bending the protection member 5b as described above, the force with which the protection member 5b presses the attachment portion 43 radially inward can be increased.

以上、本発明の実施の形態について説明してきたが、本発明は上記実施の形態に限定されるものではなく、様々な変更が可能である。   As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment, A various change is possible.

例えば、保護部材5(図4ないし図6参照)では、底部51が撓むことにより側壁部52が径方向内側へと撓むのであれば、底部51の背面56の形状は様々に変更されてよい。例えば、底部51の背面56が中心軸J1に略垂直な円環面であり、背面56の外縁部に後方へと向かって突出する環状の凸部が設けられてもよい。保護部材5a(図11ないし図14参照)においても同様に、底部51の背面56の形状は様々に変更されてよく、例えば、底部51の背面56が取付パネル9の前面91に略平行な矩形環面であり、背面56の外側部564の外縁部に後方へと向かって突出する直線状の凸部が設けられてもよい。保護部材5b(図15ないし図17参照)においても同様に、保護部材5bの背面56の形状は様々に変更されてよく、例えば、中心軸J1に垂直な背面56の外縁部に後方へと向かって突出する環状の凸部が設けられてもよい。   For example, in the protection member 5 (see FIGS. 4 to 6), if the side wall portion 52 is bent radially inward by the bottom portion 51 being bent, the shape of the back surface 56 of the bottom portion 51 is variously changed. Good. For example, the back surface 56 of the bottom 51 may be an annular surface that is substantially perpendicular to the central axis J <b> 1, and an annular protrusion that protrudes rearward may be provided on the outer edge of the back surface 56. Similarly, in the protection member 5a (see FIGS. 11 to 14), the shape of the back surface 56 of the bottom portion 51 may be variously changed. For example, the back surface 56 of the bottom portion 51 is a rectangle that is substantially parallel to the front surface 91 of the mounting panel 9. A linear convex portion that protrudes toward the rear may be provided on the outer edge portion of the outer side portion 564 of the rear surface 56. Similarly, in the protection member 5b (see FIGS. 15 to 17), the shape of the back surface 56 of the protection member 5b may be variously changed. For example, the shape of the back surface 56 perpendicular to the central axis J1 is directed rearward. An annular convex portion that protrudes in the direction may be provided.

保護部材5,5a,5bは、本体部2,2a,2bの取付パネル9への取り付けの際に、必ずしも撓んで変形する必要はない。例えば、保護部材5の側壁部52の内径が、カバー部材4の取付部43の外径よりも僅かに小さく、カバー部材4の取付部43が保護部材5の側壁部52の内側に圧入されてもよい。これにより、カバー部材4の取付部43の外側面45が、保護部材5の側壁部52により径方向内側へと押圧され、取付部43の外側面45と側壁部52の内側面57との間に摩擦力が生じる。その結果、カバー部材4の取り外しを防止することができる。保護部材5bにおいても同様であり、保護部材5bの内側にカバー部材4bの取付部43が圧入されることにより、カバー部材4bの取付部43の外側面45が、保護部材5bにより径方向内側へと押圧されてもよい。   The protection members 5, 5 a, 5 b do not necessarily have to be bent and deformed when the main body portions 2, 2 a, 2 b are attached to the attachment panel 9. For example, the inner diameter of the side wall portion 52 of the protection member 5 is slightly smaller than the outer diameter of the attachment portion 43 of the cover member 4, and the attachment portion 43 of the cover member 4 is press-fitted inside the side wall portion 52 of the protection member 5. Also good. As a result, the outer surface 45 of the attachment portion 43 of the cover member 4 is pressed radially inward by the side wall portion 52 of the protection member 5, and between the outer surface 45 of the attachment portion 43 and the inner surface 57 of the side wall portion 52. Frictional force is generated. As a result, removal of the cover member 4 can be prevented. The same applies to the protective member 5b. When the mounting portion 43 of the cover member 4b is press-fitted inside the protective member 5b, the outer surface 45 of the mounting portion 43 of the cover member 4b is moved radially inward by the protective member 5b. May be pressed.

カバー部材4の取付部43の外側面45は、必ずしも全周に亘って保護部材5により覆われる必要はない。例えば、正面視において円環の一部が切れた略円弧状(略C字状)の保護部材により、取付部43の外側面45の一部が覆われてもよい。すなわち、カバー部材4の外側面45は、保護部材5により少なくとも一部が覆われていればよい。保護部材5bにおいても同様である。   The outer surface 45 of the attachment portion 43 of the cover member 4 does not necessarily need to be covered by the protective member 5 over the entire circumference. For example, a part of the outer surface 45 of the attachment portion 43 may be covered with a substantially arcuate (substantially C-shaped) protective member in which a part of the ring is cut in a front view. That is, the outer surface 45 of the cover member 4 only needs to be at least partially covered by the protection member 5. The same applies to the protective member 5b.

図15に示す発光装置1dでは、図11に示す発光装置1cと同様に、カバー部材の取付部が本体部の内側に挿入され、パッチン止め(スナップフィット)により、カバー部材が本体部に取り付けられてもよい。   In the light emitting device 1d shown in FIG. 15, as in the light emitting device 1c shown in FIG. 11, the cover member mounting portion is inserted inside the main body portion, and the cover member is attached to the main body portion by patching (snap fit). May be.

上述の実施の形態では、保護部材によりカバー部材の外側面が内側に押圧されるが、図18に示すように、保護部材5がカバー部材4の外側面45を径方向内側に押圧することなく、外側面45に接することにより、カバー部材4の前方への移動、すなわち、本体部2の第2雄ねじ部22とカバー部材4の雌ねじ部44との係合が解除される方向へのカバー部材4の移動が妨げられてもよい。   In the above-described embodiment, the outer surface of the cover member is pressed inward by the protective member, but the protective member 5 does not press the outer surface 45 of the cover member 4 radially inward as shown in FIG. The cover member 4 moves forward by contacting the outer surface 45, that is, in a direction in which the engagement between the second male screw portion 22 of the main body 2 and the female screw portion 44 of the cover member 4 is released. The movement of 4 may be prevented.

図18に示す保護部材5は、側壁部52の前端部に、径方向内側に向かって突出する略円環状の側壁凸部524を備える。また、カバー部材4の外側面45には、取付部43の前側にて中心軸に垂直に広がる略円環状の段差面451が設けられる。保護部材5の側壁凸部524が、カバー部材4の段差面451の前側に位置し、段差面451に接することにより、カバー部材4の前方への移動が妨げられる。なお、側壁凸部524は段差面451との間に僅かな隙間を設けて段差面451の前方に配置されてもよい。この場合であっても、カバー部材4を取り外すために僅かに回転させた時点で、カバー部材4の段差面451が側壁凸部524に接する。図18に示す保護部材5の構造は、上記実施の形態に係る発光装置1,1a〜1dのいずれにも適用可能である。   The protective member 5 shown in FIG. 18 includes a substantially annular side wall convex portion 524 that protrudes radially inward at the front end portion of the side wall portion 52. The outer surface 45 of the cover member 4 is provided with a substantially annular step surface 451 that spreads perpendicularly to the central axis on the front side of the mounting portion 43. The side wall convex portion 524 of the protection member 5 is located on the front side of the step surface 451 of the cover member 4 and is in contact with the step surface 451, thereby preventing the cover member 4 from moving forward. The side wall convex portion 524 may be disposed in front of the step surface 451 with a slight gap between the side wall convex portion 524 and the step surface 451. Even in this case, when the cover member 4 is slightly rotated to remove it, the step surface 451 of the cover member 4 contacts the side wall convex portion 524. The structure of the protective member 5 shown in FIG. 18 is applicable to any of the light emitting devices 1 and 1a to 1d according to the above-described embodiment.

本体部の第1係合部とカバー部材の第2係合部との係合は、必ずしも螺合やパッチン止め(スナップフィット)による係合には限定されず、様々な構造により実現されてよい。固定部3,3aおよび保護部材5bによる本体部の取付パネル9への固定も、様々な方法により行われてよい。本体部の形状は、略円柱状や略四角柱状には限定されず、様々に変更されてよい。取付パネル9のパネル貫通孔93の形状、並びに、固定部および保護部材の開口形状も、本体部の形状に合わせて様々に変更されてよい。   The engagement between the first engagement portion of the main body portion and the second engagement portion of the cover member is not necessarily limited to the engagement by screwing or patching (snap fit), and may be realized by various structures. . The fixing of the main body portion to the mounting panel 9 by the fixing portions 3 and 3a and the protective member 5b may also be performed by various methods. The shape of the main body is not limited to a substantially cylindrical shape or a substantially quadrangular prism shape, and may be variously changed. The shape of the panel through hole 93 of the mounting panel 9 and the opening shape of the fixing portion and the protection member may be variously changed according to the shape of the main body portion.

本体部は、複数の部材が互いに着脱可能に取り付けられることにより形成されてもよい。例えば、本体部の後部202の一部が取り外されることにより、本体部内部の電球等の交換が容易とされてもよい。また、光源25として、LED素子やLED電球以外の様々なものが利用されてよい。   The main body may be formed by attaching a plurality of members to each other in a detachable manner. For example, a part of the rear part 202 of the main body part may be removed to facilitate replacement of a light bulb or the like inside the main body part. Various light sources other than LED elements and LED bulbs may be used as the light source 25.

上述の発光装置は、表示灯以外の様々な用途(例えば、照明灯)に利用されてよい。また、上述の発光装置の構造は、内部に光源を有しない様々なパネル取付用機器に利用されてもよい。この場合も、パネル取付用機器において、本体部内の構造を露出させないためのカバー部材の取り外しを防止することができる。   The above-described light emitting device may be used for various purposes (for example, an illumination lamp) other than the indicator lamp. In addition, the structure of the light emitting device described above may be used for various panel mounting devices that do not have a light source therein. Also in this case, in the panel mounting device, it is possible to prevent the cover member from being removed so as not to expose the structure in the main body.

上記実施の形態および各変形例における構成は、相互に矛盾しない限り適宜組み合わされてよい。   The configurations in the above-described embodiments and modifications may be combined as appropriate as long as they do not contradict each other.
