(1) The upper case is provided with an upper opening that exposes the upper part of the middle case upward, and the middle case is detachably attached to the upper opening with the upper part exposed upward. It may be. When configured in this way, the user can remove the middle case and the rotating brush without touching the dirty rotating brush by manually pushing the upper part of the middle case toward the lower case.
(2) All or at least the upper portion of the middle case may be transparent. When configured in this way, it is necessary for the user to visually clean the inside of the middle case through the transparent upper part, and to clean the dirty suction port body, in particular, to wash the rotary brush in the inside. It can be easily determined.
(3) The suction port body may further include a detachable driving force transmission member that transmits the rotational driving force of the motor to the rotating brush. When configured in this manner, the driving force transmission member can be easily cleaned by removing the driving force transmission member alone or together with the rotating brush from the suction port body.
(4) The suction port may be used by being connected to various types of vacuum cleaners in which the electric blower is built. By using in this way, it becomes possible for the dust collection unit of various types of vacuum cleaner main bodies to store the suction port body in a sanitary state.

  In the present invention, the vacuum cleaner 1 that can be used as a canister type is exemplified as Embodiment 1, and the vacuum cleaner that can be used as an upright type is exemplified as Embodiment 2, respectively. In addition to these, the present invention can be appropriately applied to a so-called handy type, a so-called stick type vacuum cleaner.

  The disclosed embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined not by the above description but by the scope of the claims, and includes meanings equivalent to the scope of the claims and all modifications within the scope.
