Further, since at least a part of the heads 37b, 38b of the screw 37 or the caulking rod 38 is accommodated in the space 48 of the sealing lid 44, access to the heads 37b, 38b can be made more difficult. A high fraud prevention effect is obtained.

  Further, the sealing lid 44 is bonded and fixed in the bottomed cylindrical portion 35 so that the tapered surfaces 46a and 47a of the elastic pieces 46 and 47 are in contact with the head surfaces of the screws 37 and the caulking rod 38. As a result, it is possible to prevent an unauthorized tool from entering the head side from between the elastic pieces 46 and 47 of the sealing lid 44 and the head portions 37b and 38b. In addition, the elastic pieces 46 and 47 that are pressed against the heads 37b and 38b and elastically deformed radially outwardly are in close contact with and in close contact with the heads 37b and 38b by their own elasticity. The effect of preventing the unauthorized tool from entering the head side from between the lid 44 and the heads 37b, 38b becomes higher, and a high anti-fraud effect is obtained.

  Further, in the display substrate case 27 of the embodiment, since the sealing lid 44 is bonded and fixed to the bottomed cylindrical portion 35, the time required to access the screw 37 and the crimping cage 38 from the outside can be gained. A higher fraud prevention effect can be obtained. As shown in FIGS. 6, 8, 10, and 12, the sealing lid 44 adhered and fixed to the bottomed cylindrical portion 35 is completely accommodated in the insertion hole 39 and does not protrude outward. It is possible to prevent an illegal act of gripping and removing the sealing lid 44 using the above tool. Moreover, it has a high crime prevention property against the act of inserting a tool such as a flat-blade screwdriver through the gap between the sealing lid 44 and the bottomed cylindrical portion 35 and removing the sealing lid 44. Even if the bonded state between the bottomed cylindrical portion 35 and the sealing lid 44 is released, the sealing lid 44 is not provided in the large diameter portion 39b of the bottomed cylindrical portion 35. Since the engagement step portion 50 and the engagement protrusion 42 are configured to restrict movement of the sealing lid 44 from the bottomed tubular portion 35 in a plurality of places, the bottomed tubular portion It is possible to reliably prevent the sealing lid 44 from being removed from 35. That is, the sealing lid 44 has a high defense against the act of illegally removing the sealing lid 44 mounted in the bottomed cylindrical portion 35.

  Further, in the display substrate case 27 of the embodiment, the screws 37 and the caulking rods 38 having different fixing forms are used as fixtures for connecting and fixing the connecting portion 34 and the bottomed cylindrical portion 35. Even if the heads 37b, 38b of the tools 37, 38 can be accessed, it is necessary to remove a plurality of types of fixtures 37, 38 in a form corresponding to the type of the fixtures 37, 38, which takes time. The anti-fraud effect can be improved.
