Description

  The present invention relates to a charging device for an automobile.

  A charging device for an automobile as shown in Patent Document 1 includes a charging cable for energizing a feeding means incorporated in a housing and a car (charging vehicle such as an electric car or a hybrid car). At the front end, a charging connector is provided which is connected to a connecting portion on the vehicle side. Further, at the time of non-charging, the charging connector is held by the charging connector holding portion provided in the opening formed in the front surface of the housing.

  When such a car charging device is installed outdoors, it will be exposed to rain and the like. Therefore, it is usual to provide a waterproof function to the charging device for vehicles so that rain water etc. do not enter into the case. However, as described above, since the charge connector is held by the charge connector holding portion provided at the opening, the charge connector holding portion is also provided to prevent the intrusion of rain water or the like into the housing. It is necessary to have a waterproof function, and there is a problem that the cost becomes high. Furthermore, it takes time and effort to form the opening in the case, and the formation of the opening squeezes the space inside the case.
