If the extension length of the charging cable is always fixed, the charging cable may frequently come in contact with the floor or obstacles and may cause damage or safety accidents. Ideally, the charging cable may be wound by the management of the electric vehicle driver, but in general, the management of the charging cable by the electric vehicle driver has limitations.

At least a portion of the charging cable 184 may be wound around a reel disposed inside the main body 180, and may be extended or contracted by the rotation of the reel.
