In this state, the operator rotates the connecting pipe 33 in the circumferential direction from the rotating portion 101 so that the notch 101a faces in the width direction of the case body 31, and the connecting pipe main body 102 is moved to the side of the case body 31. The floor brush 19 is in the state shown in FIG. That is, the entire connection pipe 33 is located above the case body 31, and the connection pipe 33 does not protrude in the front-rear direction of the case body 31, and is in a state along the left-right width direction of the case body 31.

  Then, the operator places the floor brush 19 on the floor surface, grips the grip portion 21 (FIG. 8), inserts the floor brush 19 into the gap S, and travels.

  Further, the operator operates the setting button 22 (FIG. 8) according to the type of the floor surface and the like to appropriately rotate the rotating brush 34.

  Then, dust is sucked together with air from the lower suction port 47 (and the front suction port 43) by the action of the negative pressure of the electric blower 27 (FIG. 8). The air sucked from the lower suction port 47 (and the front suction port 43) becomes suction air, and together with dust, the suction space 65, the connecting pipe 33, the extension pipe 18 (FIG. 8), the hose body 16 (FIG. 8) and the connecting pipe part The vacuum cleaner main body 13 (FIG. 8) is sucked into the main body dust collecting chamber 15 (FIG. 8), and dust is collected by the dust collecting portion in the main body dust collecting chamber. Then, the suction air in which the dust is collected is sucked into the suction side of the electric blower 27 (FIG. 8) in the electric blower chamber, passes through the electric blower 27 (FIG. 8) while cooling, and is exhausted. Thus, the air is exhausted from the exhaust hole of the cleaner body 13 (FIG. 8) to the outside of the cleaner body 13 (FIG. 8).

  When the cleaning is completed, the operator appropriately operates the setting button 22 (FIG. 8) to stop driving the electric blower 27 (FIG. 8).

  As described above, in the above-described embodiment, the rear side of the case body 31 with respect to the opening 68 provided with the rear opening 66 opened on the rear side of the horizontally long case body 31 and the upper opening 67 opened on the upper side. In the state where the connection opening 82 for connecting the connection pipe 33 is formed in the pipe connection part 81 movable from the upper side to the upper side, the pipe connection part 81 is moved to the respective positions on the rear side and the upper side of the case body 31. The connection opening 82 communicates with the rear opening 66 or the upper opening 67, and the opening 68 is closed with the closing portion 32 except for the connection opening 82. For this reason, during normal cleaning, as shown in FIGS. 1 and 2, the pipe connecting portion 81 is positioned on the rear side of the case body 31, and a large area is used by using the left and right width dimension L1 of the case body 31. 4 and 5, when cleaning the gap S narrower than the left and right width dimension L1 (FIG. 2) of the case body 31, the pipe connection portion 81 is connected to the upper side of the case body 31. The gap S can be cleaned using the front-rear dimension L2 (FIG. 2) smaller than the left-right width dimension L1 (FIG. 2) of the case body 31. Therefore, in both normal cleaning and cleaning of the narrow gap S, the vacuum is maintained by sucking dust together with air from only the common suction air passage through the common lower suction port 47, and the right and left widths of the case body 31. The gap S narrower than the dimension L1 (FIG. 2) can be effectively cleaned.

  That is, the negative pressure of the electric blower 27 (FIG. 8) acts on the lower suction port 47 both during the normal cleaning shown in FIGS. 1 and 2 and during the cleaning of the gap S shown in FIGS. (And the front suction port 43) only, and no other suction air passages are formed, so that dust can be efficiently sucked from the lower suction port 47.

  Further, when cleaning the gap S shown in FIGS. 4 and 5, the entire connecting pipe 33 is positioned above the case body 31, so that the gap up to the front-rear dimension L <b> 2 (FIG. 2) of the case body 31 is minimized. The floor brush 19 can correspond to the cleaning of S.

  Further, the opening 68 is opened to the rear side and the upper side of the case body 31, and the pipe connection portion 81 of the closing portion 32 is slid to move the connection pipe 33 to the rear side and the upper side of the case body 31. By configuring, for example, the case body itself is divided into two, the suction opening is formed in one case body, and the other case body is kept connected to the rear side and the upper side with respect to the one case body Compared with the configuration in which the width of the case body can be varied by turning and the case body 31 can be inserted into the gap, the opening area of the lower suction port 47 is increased without increasing the overall size of the case body 31 more than necessary. Therefore, dust can be sucked in efficiently during normal cleaning or when cleaning the gap S, and the cleaning efficiency is improved.

  Then, by making the shutters 83 and 84 that open and close the openings 66 and 67 separate from the pipe connecting portion 81, the size of the closing portion 32 can be reduced as compared with a case where these are integrally formed. That is, when the pipe connecting portion 81 and the shutters 83 and 84 are integrated, the pipe connecting portion 81 must have a size that continues at least from the rear opening 66 to the upper opening 67, whereas the pipe connecting portion 81 When the shutters 83 and 84 are operated by abutment with the pipe connecting portion 81, the shutters 83 and 84 have a minimum size capable of closing the openings 66 and 67. Since the pipe connecting portion 81 can have a minimum size that allows the connection opening 82 to communicate with the openings 66 and 67, the entire length of the pipe connecting portion 81 can be moved between the shutters 83 and 84. The size can be suppressed, and the floor brush 19 can be made compact. In addition, since the size of the pipe connecting portion 81 for sliding the outer peripheral surface of the bending portion 63 can be reduced, sliding resistance with the outer peripheral surface of the bending portion 63 can be suppressed, and the operability of the closing portion 32 is improved.

  Further, by providing the fixing means 85 that can fix the pipe connecting portion 81 on the rear side and the upper side of the case body 31, respectively, even when cleaning, the connection opening 82 communicates with any one of the rear opening 66 and the upper opening 67. The state can be reliably maintained.

  In the above embodiment, the opening 68 is continuous between the side surface side and the upper surface side as long as the opening 68 opens at least on the side surface side (rear side) and the upper surface side of the case body. Also good.

  Further, the closing portion 32 may selectively open and close the side surface side or the upper surface side of the opening 68 with the pipe connecting portion 81 itself without providing at least one of the shutters 83 and 84.

  Further, the rotating brush 34, the front suction port 43, the front cover 44, and the like are not essential components, and the driving means for rotating the rotating brush 34 may have any configuration such as an air turbine. Further, the rotating brush 34 is not configured to be rotated by the driving means, but may be rotated by contact resistance with the floor surface.

  And the structure of the vacuum cleaner 11 is not limited to the said structure.
