Mainly when using a vacuum cleaner in a car, there is no need to take it inside the house to charge it, which saves time and effort. In addition, a charger consisting of a transformer, a rectifier, etc. is not required, and the car plug 36 for connecting the electric appliance 27 to the storage battery of the automobile and the car plug 36 for connecting the charging circuit 41 to the storage battery are shared. This simplifies wiring and reduces costs.

Further, as described above, when the circuit connecting the curve jig 36 and the charging circuit 41 is closed, both drive circuits are open, and when any drive circuit is closed, both drive circuits are open. Since the car plug 36 and the charging circuit 41 are open, for example, when current flows through the charging circuit 41, the output side of the charging circuit 41 will not be short-circuited via the electric motor [27]. . Therefore, excessive current will not flow through the charging circuit 41, and failure of the charging circuit 41 can be prevented. That is, it is possible to prevent misuse, such as charging by forgetting to turn off the switch 33.

Moreover, since there is no need to provide a switch for switching between the connection of the car plug 36 and the electric Ia 27 and the connection of the car plug 36 and the charging circuit 41 separately from the main body switch 33, the cost can be reduced.゛Also, as mentioned above, the electric motor 27 is stopped, the secondary battery 28 is charged, and the automatic tlJ
The driving of the electric gate 27 by the car's storage battery and the driving of the electric motor 27 by the secondary battery 28 are controlled by a single switch knob 34.
