When the second male screw portion 22 of the main body 2 is referred to as a “first engagement portion” and the female screw portion 44 is referred to as a “second engagement portion”, the second engagement portion engages with the first engagement portion. Thus, the cover member 4 is attached to the main body 2.

  FIG. 4 is a perspective view showing the protection member 5. As shown in FIGS. 3 and 4, the protection member 5 includes a bottom 51 and a side wall 52. The bottom 51 has a substantially annular plate shape having a substantially circular opening 53 into which the main body 2 is inserted. The diameter of the opening 53 is larger than the outer diameter of the first male screw portion 21 of the main body portion 2 and smaller than the outer diameter of the flange portion 23. The bottom 51 is sandwiched between the back surface of the flange portion 23 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 of the main body portion 2 through 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.

  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.

  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.

  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.

  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.

  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 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.

  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.

  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 that is a portion near 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

  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.

  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.

  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.

  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.

  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.

  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.

  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.

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.

  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.

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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  The configurations in the above-described embodiments and modifications may be combined as appropriate as long as they do not contradict each other.
