This is because, at the bottom of the groove G, the protective cover 2 that is about to fall off the bezel 3 by gravity is fastened.
  • the hook provided in the facing portion 3a of the bezel 3 is also protruded.
  • a part of the fat frame 39 may be used to prevent the protective cover 2 from falling off (this part is referred to as a drop-off preventing piece R).
  • the fall-off prevention piece (drop-off prevention portion) R avoids and moves (in the direction of the arrow X) so as not to obstruct the attachment.
  • the fall-off preventing piece R is locked and moved (in the arrow Y direction) so as to suppress the movement of the protective cover 2.
  • the fall-off prevention piece R can be moved in an avoidance manner.
  • the drop-off preventing piece R is engaged with the protective cover 2 and stops moving the protective cover 2. For this reason, the fall-off prevention piece R does not cause any obstacle when the protective cover 2 is attached / detached, but effectively stops the movement of the protective cover 2 after the protective cover 2 is attached.
  • avoidance movement and the locking movement described above are movements in the in-plane direction on the surface 3aa of the facing portion 3a.
  • the movement of the drop-off prevention piece R is not limited to this.
  • avoidance movement and locking movement in a direction perpendicular to the in-plane direction to be applied may be used.
  • the drop-off prevention piece R may be positioned on the facing portion 3a constituting the short side where the attachment portion 5 in FIG. 6 is not provided. This is because, when the protective cover 2 is attached to or detached from the bezel 3, the fall-off prevention piece R moves while avoiding being embedded in the bezel 3 so as not to obstruct the attachment. This is because, after the protective cover 2 is mounted, it moves so as to protrude from the surface 3aa of the facing portion 3a so as to suppress the movement of the protective cover 2.
  • the fall-off prevention piece R is separated from the protective cover 2 when the protective cover 2 is attached to the bezel 3 and when the protective cover 2 of the bezel is released. After attaching the protective cover 2 to the bezel 3, it is sufficient that the protective cover 2 is in contact with the protective cover 2.
  • the protective cover 2 is provided with a protrusion that fits into the hole, and the protrusion and the hole fit together to protect the bezel 3 from falling off.
  • the cover 2 may be allowed to stay (in such a case, the hole can be said to be a drop-off prevention part R).
  • the shape and material of the drop-off prevention piece R are not particularly limited. For example, metal or oil Another member such as a drop-off prevention piece R may be used.
  • the material of the attachment portion 5 is not particularly limited, and various materials may be used.
  • the mounting portion 5 described above is formed by making a cut in the facing portion 3a of the bezel 3, and bending the cut portion so as to protrude toward the surface 3aa.
  • the present invention is not limited to this.
  • the attachment portion 5 may be formed by providing another member on the surface 3aa of the facing portion 3a.
  • an opening may be provided in the facing portion 3a of the bezel 3, and a resin frame 39 that protrudes from the opening may be protruded, and the protruding portion may be used as the attachment portion 5 (this attachment portion 5 is also provided on the surface 3aa of the facing part 3a!
  • the mounting portion 5 is a force that has listed the one having the groove G, but is not limited thereto.
  • the mounting portion 5 may be a screw or an insertion / removal pin that can be used to stop or remove the protective cover 2 after the protective cover 2 is arranged at a desired position on the bezel 3.
  • the member required for attaching the protective cover 2 to the bezel 3 can be said to be the attachment portion 5.
  • the mounting part 5 allows the protective cover 2 to be detached from the bezel 3, such as a groove G screw.
