The lid 7 is removed only while the plug 6 is not projected. A switch comprising a contact spring and a contact plate which make contact with each other when pressed by the hook of the lid 7 is disposed inside an equipment main body. The switch is inserted into a charging circuit located between the charging plug 6 and a storage battery 12, and breaks the circuit when the lid 7 is removed.
