An embodiment of the display device according to the present invention will be described with reference to the sectional views shown in FIGS. The holding member is configured such that the screw portion 102 of the holder portion 1 is screwed with the screw portion 204 of the support portion 2,
It is mounted on the substrate 5 by the support portion 2 having a strong elastic force. The holder portion 1 screwed with the support portion 2 has a cylindrical elastic body portion 3 made of a flexible material such as a foamed resin at an integrally molded tip. Leg 2 of support 2 for screwing and supporting holder 1
02 and the snap portion 201 at the end thereof are inserted into the mounting holes 501 of the substrate 5, the base portion 203 abuts on the front surface of the substrate 5, the snap portion 201 engages on the back surface, and is elastically mounted.

The holder portion 1 screwed and supported by the support portion 2 which is elastically engaged with and fixed to the mounting hole 501 of the substrate 5 by the snap portion 201 of the support portion 2, emits light of the LED 4 on the cylindrical inner wall portion 101. The protruding dimension A from the front surface of the substrate 5 (the base 203 of the support portion 2) through the support portion 2 and the holder portion 1 to the distal end portion of the elastic portion 3 is accommodated in the boss 7 from the back surface of the panel 6. Larger than height B, A> B (1-2 mm
(Protruding state) so that the holder 1 or the elastic body 3
Is rotated to adjust the protrusion size by screwing.

When the substrate 5 is screwed into the mounting hole 701 of the boss 7 with the screw 8 via the mounting hole 503, the distal end of the elastic body 3 held integrally with the holder 1 is made thin. The inclined surface 301 flexibly and closely contacts the panel 6 (or around the optical path on the back surface of the display window), and the elastic body portion 3 covers around the optical path of the light emitting unit 401 to the display window 601, so that there is no light leakage. It is compressed and deformed in the state. Holder part 1
Light-emitting part 40 of LED 4 held near inner wall 101
Light from one and light from a plurality of other display windows 601 provided close to the panel 6 do not leak to the other display windows.

In this case, even if there is some variation in the dimensional difference between A and B due to the variation in the thickness of the substrate 5 or the like, the holder 1 screwed to the support 2 is rotated so that A> B. The elastic member 3 is elastically deformed and brought into contact with the inner wall surface of the panel 6 or the display window 601 by adjusting the amount of protrusion of the holding member by adjusting the screw engagement, and the inner wall surface of the panel 6 or the display window 60 is securely adjusted.
1 and the supporting part 2 and the holding part 1 with which the holding member is screwed even when receiving an external vibration.
There is no danger that the screw will rotate and loosen, causing light leakage to other display windows or the like.

A display window 60 of the panel 6 of an audio device or the like.
In a display device that emits light from a light source such as an LED 4 to a display unit 1, a support unit 2 made of a resin having high hardness and elasticity for screwing and supporting a holder unit 1 of a holding member, a holder unit 1 and an elastic body unit 3 are provided. Is made of a different kind of resin, and the holder 2 is formed by integral molding.
Of the panel 5 is snapped to the substrate 5 by the leg portion 202 and the snap portion 201. The elastic portion 3 is provided at one end around the optical path of the display window 601 of the panel 6 due to the elasticity of the elastic portion 3 made of a flexible resin. Since it is formed so as to be in close contact, it is possible to prevent light from leaking into the inside of the device from the light source such as an LED and the tip of the holding member, and when the substrate 5 is fixed to the boss 7 of the panel 6 with the screw 8 and assembled, Accidents such as deformation and breakage due to excessive stress on the panel 6 and the substrate 5 can be prevented.

Also, even if the height of the boss 7 for holding the substrate 5 and the holder 1 of the holding member is not made to be precise, the difference in the shrinkage limit due to the elasticity of the elastic body 3 of the holder 1 can be reduced. If A> B, light leakage, deformation and breakage can be prevented. Further, by preventing light leakage, each display window can prevent light leakage from other LEDs even when a large number of LEDs and light emitting holes are arranged in a concentrated manner on the panel.

[0020]

According to the present invention, snap fixing can be performed by the elastic force of the resin of the supporting portion for supporting the holder of the holding member, and the protrusion dimension can be adjusted by screwing and supporting the holder. Due to the flexibility of the elastic body at the tip of the holder, it comes close to the periphery of the display window, preventing light from leaking from the tip of the holding member to other parts. No stress is applied, and it is possible to prevent the panel from being deformed and the substrate from being damaged.
