[0043] [C-3] Intercom panel mounting structure The mounting structure of the interphone panel 5 according to this embodiment will now be described. The front surfaces of the magnets 8 fixed to the exposed surfaces of the lower vertical pieces 65 in the lower part of the upper mounting element 6' and the upper vertical pieces 75 in the upper part of the lower mounting element 7' are positioned inside a vertical plane passing through the back surface (the back surface of the surface portion 301) of the face portion 30 (face portions 300 and 301) of the entrance panel 3. When the interphone panel 5 is mounted to the entrance panel 3, the upper and lower ends of the left and right abutment portions 55 protruding from the back surface of the face portion of the interphone panel 5 are magnetically attached in a state of abutment against the magnet 8, and the back surface of the face portion of the interphone panel 5 and the magnet 8 are not in contact with each other.

[0044] The back surface (resin tapes 520, 521, 522) of peripheral portion 52 of surface material 50 of interphone panel 5 is in a state of non-contact with the surface of face portion 30 of entrance panel 3. Back surface material 51 of interphone panel 5 is located within opening 4 of face portion 30 of entrance panel 3, and peripheral edges 510, 511, 512 of back surface material 51 are in a state of non-contact with peripheral edges 40, 41, 42 of opening 4 of face portion 30 of entrance panel 3.

[0045] In this embodiment, the four corners of the interphone panel 5 (the upper and lower ends of the left and right abutment portions 55) are fixed by the magnetic force of four magnets 8, preventing the interphone panel from partially floating relative to the entrance panel due to component installation errors, etc. [Explanation of symbols]
