(5) The locking means may have a main body locking means for detachably locking the extension pipe and the vacuum cleaner main body. By doing so, the lock between the vacuum cleaner main body and the extension pipe can be easily released by operating the grip portion.

(6) The main body locking means may release the lock of the main body locking means when the grip portion is moved toward the suction port body. By doing so, the moving direction of the grip portion and the moving direction for removing the extension pipe from the vacuum cleaner main body are in the same direction, so that the user can move the grip portion and extend from the vacuum cleaner main body. The operation of removing the tube can be performed at the same time, and the convenience of the user can be further improved.

The present invention is not limited to the above-described embodiment, but is substantially the same as the configuration shown in the above-described embodiment, a configuration having the same action and effect, or a configuration capable of achieving the same object. May be replaced with.

Further, in each embodiment, a so-called stick type vacuum cleaner has been described as an example, but the type of vacuum cleaner is not particularly limited, such as a handy type and a canister type.
