  And when removing the linear dust wound around the 1st filtration part 42, the dust isolation | separation dust collection part 7 is operated as follows by a user.

  First, the lid body 36 is opened. At this time, the dust in the dust collecting chamber 69 is discarded, and the linear dust D wound around the first filtration part 42 remains in the container main body 35.

  Next, the cup member 43 that is easy to handle directly from the open end 52 of the container body 35 is rotated in the circumferential direction. At this time, the 1st filtration part 42 integral with the cup member 43 also rotates, and the cylindrical frame 48 and the 1st filtration part 42 are displaced relatively to the circumferential direction. Then, the claw portion 49 is detached from the groove 77 and moves to the slit 75. As a result, the fixation between the cylindrical frame 48 and the first filtration part 42 is released.

  Next, the first filtration part 42 is pulled out from the cylindrical frame 48.

  At this time, as shown in FIG. 6, the claw portion 49 moves following the slit 75 due to the relative displacement (translational displacement in the direction of the center line C) between the cylindrical frame 48 and the first filtration portion 42. The linear dust D is gradually gathered while approaching the entrance portion of the slit 75.

  Eventually, the claw portion 49 reaches the open end of the slit 75 as shown in FIG. At this time, the linear dust D is collected by the claw portion 49 toward the front end of the cylindrical frame 48.

  Then, as shown in FIG. 8, the claw portion 49 comes out of the slit 75. At this time, the linear dust D is removed from the container main body 35 while hanging on the claw portion 49. Note that the linear dust D remaining on the claw portion 49 moves to the first filtration portion 42 having a smaller diameter than the outer diameter of the cylindrical frame 48, and thus is easy to remove.

  As described above, the dust separation and collection unit 7 and the vacuum cleaner 1 according to the present embodiment include the bone member 71 extending along the first filtration unit 42 and the claw portion 49 that moves following the slit 75.
