In the figure, the reference numeral 1 designates a housing having an oval-shaped mounting hole 2 and forming a part of a camera case (not shown). A strap fitting 6 as a hanging fitting having a flange 4 in contact with the outer peripheral edge of the hole 2 and a screw hole 5 opening in the tip end face is provided on the flange end face 4a of the strap fitting 3 via the housing 1 and both ends. A reinforcing plate 8 having an insertion hole 7 opening on the surface is a screw inserted into the insertion hole 7 of the reinforcing plate 6 and screwed into the screw hole 5.

Next, the mounting structure of the hanging fitting shown in FIG. 6 will be described with reference to FIG.
The screw holes 1 open on the parting line surface
2 and a housing 14 having a positioning projection 13 projecting in the same direction as the opening direction of both screw holes 12 and forming a part of a camera case (not shown); A strap member 17 as a hanging member made of a sheet metal having a screw insertion hole 15 corresponding to the screw hole 12 and a positioning hole 16 facing the protrusion 13 is provided on the strap member 14 so as to be movable, and a strap belt (see FIG. (Not shown) is a screw which is inserted into the screw insertion hole 15 and screwed into the screw hole 12.

[0006]

By the way, in the former, as a measure for preventing the screws from being loosened, the strap fitting 3 is formed by an oval-shaped hanging fitting having an outer peripheral surface adapted to the inner peripheral surface of the mounting hole 2. In addition, since the screw 8 is formed of a screw with an anti-loosening agent, a part of the outer peripheral surface of the strap fitting 3 is D-cut and the screw 8 is formed.
In this case, it is necessary to apply a loosening preventive agent, and the production cost increases. Also, the fact that the D-cut processing is applied to the strap fitting 3 as a rotation preventing measure prevents the strap fitting 3 from moving in the direction in which the strap belt (not shown) is suspended, and the strap fitting 3 cannot be moved. There is also a problem that stress is apt to act on the surface. Further, since the mounting hole 2 is to be opened in the wall portion 1a of the housing 1, the fastening direction of the screw 8 is a direction perpendicular to the parting line surface (opening end surface) of the housing 1, so that the screw is fastened. Strap fitting 3 to secure space
There is a disadvantage that the mounting position is limited, and the design is restricted. Furthermore, since the mounting hole 2 has an oval shape, a sealing member such as an O-ring does not adhere to the inner peripheral surface of the mounting hole 2, and there is a disadvantage that the reliability of waterproofing and dustproofing is reduced.

On the other hand, in the latter case, the strap fitting 1
4 has a substantially rectangular shape, so that the whole becomes large and there is a problem that the design is restricted. In addition, since the strap metal 14 is partially exposed outside the camera case, there is also a problem that the strap metal 14 hits the user's hand when holding the housing 11 (camera case), which causes discomfort. Was. Further, in order to form a recess a in which the head 18a of the screw 18 faces the strap fitting 14, it is necessary to perform milling on the strap fitting 12,
There is a disadvantage that the production cost increases. Furthermore,
There is also an inconvenience that the gap formed between the strap fitting 14 and the housing 11 is large, and the reliability in waterproofing and dustproofing is reduced.

[0008] The present invention has been made in view of such circumstances, can reduce the manufacturing cost, can suppress the occurrence of stress on the hanging bracket at the time of use, and can be waterproof and dustproof. It is intended to provide a mounting structure of a hanging fitting and an electronic device which can enhance the reliability of the electronic device.

[0009]
