  The mounting structure of the electric hot water heater 2 according to the present embodiment described above protects the rubber hoses 71 and 72 so as to cover the edge 43 along the edge 43 facing the rubber hoses 71 and 72 of the body side bracket 4. Since the flange 621 is provided, the flange 621 protects the rubber hoses 71 and 72. Thereby, even if the vehicle body inner wall (side sill 12) is deformed inward in the vehicle width direction due to a side collision of the automobile 1, damage to the rubber hoses 71 and 72 can be avoided.

  Further, in the mounting structure of the electric hot water heater 2 described above, since the flange 621 is provided on the heater outer bracket 6, it is not necessary to configure the flange 621 as a separate part from the heater outer bracket 6.

  In addition, in the mounting structure of the electric hot water heater 2 described above, a recess 431 having an opening in the vehicle width direction is provided at the edge 43 of the body side bracket 4, and a flange 621 that protects the recess 431 is provided at the heater outer bracket 6. . Thereby, even if the vehicle body inner wall (side sill 12) is deformed inward in the vehicle width direction due to a side collision of the automobile 1, the rubber hoses 71 and 72 are received in the recesses 431 and the rubber hoses 71 and 72 are not completely crushed. .

  Moreover, the mounting structure of the electric hot water heater 2 described above is provided with a pair of arms 64 and 65 on the outer side in the vehicle width direction of the heater outer bracket 6 and in the vehicle width direction from the position where the arms 64 and 65 overlap the body side bracket 4. Beads 641 and 651 for increasing rigidity were formed in the outer region. As a result, when a predetermined load is exceeded, the arms 64 and 65 are bent between a position overlapping the body side bracket 4 and the beads 641 and 651 formed on the front end side. Therefore, the electric hot water heater 6 is not pushed inward in the vehicle width direction.

  Moreover, since the mounting structure of the electric hot water heater 2 described above is provided with the flange 621 on the inner side in the vehicle width direction than the beads 641 and 651, the rubber hoses 71 and 72 are not completely crushed even if the arms 64 and 65 are bent. .

  In the above-described embodiment, the electric hot water heater mounting structure has been described. However, the electric device to be attached is not limited to the electric hot water heater, and may be an electric device other than the electric hot water heater. In addition, the connection member connected to the electric device is not limited to the rubber hose, and may be a harness that electrically connects the electric device and the vehicle-mounted electrical component.

  The present invention can prevent the connecting member from being damaged at the edge of the body side bracket even if the inner wall of the vehicle body is deformed inward in the vehicle width direction due to a side collision of the automobile. It is suitable for the mounting structure.
