The locking by the locking clamp 89 is held by the urging of the coil spring 91 so that the coiled spring 91 is fixed to the main body case 25 in a locked state.

  According to the embodiment described above, the dust collecting case 45 is guided in a direction to be attached to and detached from the main body case 25, and the second separating portion 42 (separation unit U) is guided by the guide in the removing direction from the main body case 25. A dust collection case is provided by separating the dust collection case 45 and providing a guide portion 86 for connecting the second separation unit 42 (separation unit U) and the dust collection case 45 by a guide in the mounting direction with respect to the main body case 25. 45 can be formed smaller than the first separation portion, and only the dust collecting case 45 can be detached from the main body case 25 separately from the first separation portion. For this reason, it becomes possible to discard the coarse dust accumulated in the first separation unit 41 and the fine dust accumulated in the dust collection case 45 by different methods.

  That is, the coarse dust collected in the first separation unit 41 is discarded in a trash box or the like, while the fine dust collected in the dust collection case 45 easily rises when discarded in the trash box or the like. It is possible to dispose of dust with a disposal method suitable for its size, such as by inserting it into the back of the trash can and discarding it, or by washing and removing the dust collection case 45 with water. Becomes easier.

  Moreover, since the dust collection case 45 can be formed smaller than the first separation part 41, for example, even when the dust collection case 45 is washed with water, it does not take time to dry or wipe off the water. Maintainability can be improved, such as being able to return.

  Further, by making the second separation part 42 (separation unit U) removable from the main body case 25, dust and the like attached to the second separation part body 61 of the second separation part 42 can be removed, and the second separation part 42 is easier to care for.

  Further, each of the second separation part 42 (separation unit U) and the dust collecting case 45 is removed from the main body case 25 by the upper coil spring 76 and the lower coil spring 85, and the second separation part 42 (separation unit 42) is separated. U) and the dust collection case 45 are urged to a position where they are separated from each other, so that the second separation portion 42 (separation unit U) and the dust collection case 45 can be connected to each other only by releasing the locking by the locking clamp 89. Since it is separated, the separation between the second separation portion 42 (separation unit U) and the dust collecting case 45 becomes easier.

  Then, the dust collecting case 45 is attached to the main body case 25 by the projection 87 provided on the dust collecting case 45 so that the second separating portion 42 (separation unit U) is linked to the main body case 25. It is possible to push the second separation part 42 (separation unit U) into the upper recess 34a of the mounting recess 34 of the main body case 25 by simply pushing it so as to be attached to the lower recess 34b of the mounting recess 34 of the dust collecting case. 45 and the second separation portion 42 (separation unit U) can be attached to the main body case 25 more easily.

  As the urging means, for example, either the second separation unit 42 (separation unit U) or the dust collecting case 45 is urged, and the second separation unit 42 is interlocked with one movement. The dust collection case 45 may be separated from each other.

  Moreover, the convex part 87 may be provided in the 2nd separation part 42 side, and may be provided in both the 2nd separation part 42 and the dust collection case 45, respectively.

  Further, the structure for locking the separation unit U including the second separation portion 42 and the dust collecting case 45 to the main body case 25 is not limited to the locking clamp 89.

  And although one Embodiment of this invention was described, this embodiment is shown as an example and is not intending limiting the range of invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
