Further, at this time, the operator inserts the projecting piece 66 into the space 351 on the right side of the hook projection 35, and arranges the claw 650 of the regulation structure 65 on the right side of the retrograde regulation portion 340 (through hole). , Adjust the position of the terminal unit 6 in the left-right direction.

Next, the operator moves the terminal unit 6 in one direction (leftward) while bringing the rib 67 into contact with the flange portion 34. That is, the operator moves the terminal unit 6 to the left while sliding the mounting unit 3 on the surface of the terminal unit 6. As a result, as shown in FIGS. 10 and 12, the claw 650 of the regulation structure 65 is inserted into the retrograde regulation portion 340 (through hole). Further, the top plate portion 662 (see FIG. 8) of the projecting piece 66 is placed on the hooking protrusion 35, and the pillar portion 661 (see FIG. 8) of the projecting piece 66 moves to the rear of the hooking projection 35.

With the above, the third step of mounting the terminal unit 6 on the mounting unit 3 is completed. That is, at the completion of the third step, the terminal unit 6 is arranged at a predetermined mounting position as shown in FIGS. 10 and 12. When the terminal unit 6 is in the mounting position, the first mounting portion M1 of the terminal unit 6 is supported from the front by the first support portion S11 of the mounting unit 3, and the second mounting portion M2 of the terminal unit 6 is mounted. It is supported from behind by the second support portion S12 of the unit 3.

More specifically, the terminal unit 6 has a regulation structure 65, a protrusion 66, and a rib 67 as the first mounting portion M1. The regulation structure 65 is supported from the front by the peripheral edge portion of the retrograde regulation portion 340 (through hole) of the flange portion 34 (first support portion S11). The pillar portion 661 of the projecting piece 66 is supported from the front by the hooking projection 35 (first support portion S11). The rib 67 is supported from the front by the flange portion 34.

Further, as described above, the flange portion 34 and the hooking protrusion 35 also serve as the first support portion S11 and the second support portion S12, respectively.

By pushing the claw 650 of the regulation structure 65 backward, the terminal unit 6 can be moved left and right from the mounting position. As a result, the terminal unit 6 can be removed from the mounting unit 3.

Further, when the terminal unit 6 is in the mounting position, the movement restricting unit 36 is located below the housing 60 of the terminal unit 6. The downward movement of the terminal unit 6 is restricted by the housing 60 coming into contact with the movement restricting portion 36. That is, the movement restricting portion 36 of the support portion S1 restricts the terminal unit 6 from moving from the mounting position along a direction orthogonal to both one direction (leftward) and the front-back direction (that is, downward). ..

As described above, when the terminal unit 6 is in the mounting position, the movement of the terminal unit 6 is restricted. For the movement of the terminal unit 6 in the front-rear direction, the first mounting portion M1 of the terminal unit 6 is supported by the first support portion S11 from the front, and the second mounting portion M2 is supported by the second support portion S12 from the rear. It is regulated by that. The movement of the terminal unit 6 in the left-right direction is regulated by the regulation structure 65 and the retrograde regulation unit 340. The movement of the terminal unit 6 in the left-right direction is also restricted by the protrusion 66 being arranged in the gap 350 and the space 351. The upward movement of the terminal unit 6 is restricted by the contact between the upper surface of the housing 60 (second housing 62) and the flange portion 34. The downward movement of the terminal unit 6 is restricted by the housing 60 coming into contact with the movement restricting portion 36. Further, the downward movement of the terminal unit 6 is also restricted by the contact of the top plate portion 662 of the projecting piece 66 with the hooking protrusion 35.

As a result, the thickness of the portion of the mounting unit 3 that protrudes forward of the structure 900 can be reduced as compared with the case where a part of the support portion S1 is provided in front of the structure 900. .. In FIG. 12, the structure 900 is illustrated by a virtual line. In the present embodiment, among the mounting units 3, a plurality of mounting plates 31, a plurality of holding protrusions 33, and an outer frame portion 37 are provided in front of the structure 900.

Further, as shown in FIG. 12, the second mounting portion A2 (holding projection 33) is larger than the front surface 90F of the structure 900 when the first mounting portion A1 (mounting plate 31) is mounted on the structure 900. Located in front. More specifically, at least the front end portion of the second mounting portion A2 (holding projection 33) is from the front surface 90F of the structure 900 when the first mounting portion A1 (mounting plate 31) is attached to the structure 900. Also located in front. As a result, as compared with the case where the second mounting portion A2 is located behind the structure 900, the first mounting portion A1 (mounting plate 31) is attached to the second mounting portion A2 in a state of being mounted on the structure 900. Easy to install the intercom master unit 1. Further, the intercom master unit 1 is attached to the second attachment portion A2 in front of the structure 900. Therefore, unlike the case where the second mounting portion A2 is arranged inside the through hole 901 of the structure 900 or behind the structure 900, the size of the intercom master unit 1 is made larger than the size of the through hole 901. obtain.
