Conventionally, in this type of rechargeable vacuum cleaner, the main body of the vacuum cleaner and the charging stand are electrically connected at the time of charging, and are also mechanically connected. For example, it is known that a plug provided on one of the cleaner main body and the charging stand is electrically and mechanically connected by being connected to a jack provided on the other. There is also known a cleaner in which a main body is held by a fitting mechanism provided on a charging stand.

[0003] However, in the above-described structure, the cleaner body and the charging stand must be mechanically fitted each time the cleaner body and the charging stand are attached and detached. Unless both of them are held or the charging stand is fixed to a wall, a floor, or the like, there is a problem that the cleaner body cannot be attached or detached.

[0004] On the other hand, rechargeable vacuum cleaners as described in Japanese Patent Publication No. 62-52666 and Japanese Patent Publication No. Hei 4-1618 are also known. The former rechargeable vacuum cleaner includes a cleaner main body having a rechargeable battery (secondary battery), a fan motor, and a dust case, a holding unit for mounting and holding the cleaner main body, and the holding unit provided on the holding unit.
