  In the vehicle charging device configured as described above, the state in which the closing member 70 is removed from the connector housing portion 50 is the charging standby state, that is, the state during operation. In this charging standby state, if the connector 41 is moved upward and the grip portion 42 is separated from the support base 51ab, it can be removed from the connector accommodating portion 50 as it is. Therefore, the secondary battery mounted on the vehicle can be quickly charged by appropriately routing the charging cable 30 and connecting the connector 41 to the charging terminal of the vehicle. When charging is accommodated, if the connector 41 is inserted into the accommodation port 51a again and the grip portion 42 is placed on the support base 51ab, the connector 41 having a larger outer peripheral dimension than the grip portion 42 is brought into contact with the front panel 51. By contact, the movement of the connector 41 in the direction deviating from the accommodation port 51a is restricted, and the connector 41 is maintained in the accommodated state. In the state in which the connector 41 is accommodated, the tip of the connector 41 is surrounded by the panel constituting the connector accommodating portion 50, and a situation in which foreign matter such as water or dust adheres can be prevented.

  On the other hand, after the connector 41 of the operation unit 40 is inserted into the housing port 51a, the front cover 71 is disposed at the closed position with the hook piece 73 of the closing member 70 inserted into the hook groove 51b. When the locking operation is performed, the lower end portion of the closing member 70 is locked to the base wall portion 51A of the front panel 51 via the hook piece 73, and the upper end portion of the closing member 70 is locked to the front panel 51 by the locking means 60. The top wall 51B is locked. That is, it becomes difficult to remove the closing member 70 from the connector housing portion 50. In this state, when the operation unit 40 is moved in the direction for removing the operation unit 40 from the accommodation port 51a of the connector accommodation unit 50, the connector 41 of the operation unit 40 comes into contact with the closing member 70, and further movement is prevented. The Thereby, even when the vehicle charging device is not in operation, such as at midnight, mischief such as removal of the connector 41 from the connector housing portion 50 can be prevented.

  Here, during the operation described above, since the closing member 70 is removed from the connector housing 50, the locking means 60 provided on the closing member 70 is also removed from the connector housing 50. Accordingly, if the closing member 70 is placed under the management of a management room or the like during operation, it becomes difficult for a third party to perform an unauthorized operation such as destroying the locking means 60. Thus, if the locking means 60 is locked during non-operation, it becomes difficult to always remove the closing member 70 from the connector housing 50, and the connector 41 is removed from the connector housing 50 even during non-operation, such as at midnight. Can be prevented more reliably.
