First, the operation of inserting the filter 3 into the storage portion 23 from the one suction port 40 will be described. As shown in FIG. 6, when the filter 3 is inserted into the suction port 40 from the one end 33 a side, the one end 33 a of the filter 3 contacts the side surface 24 b of the engaging portion 24. The side surface 24b of the engaging portion 24 has a taper in the insertion direction of the filter 3, and the taper guides the one end 33a of the filter 3 to the suction port 40 without being locked by the engaging portion 24. .

Rails 51 for guiding the filter 3 to the storage position of the storage unit 23 are formed on the flat panel 30 at positions facing one end 33c and the other end 33d of the filter 3 in the lateral direction. When the filter 3 is inserted into the suction port 40 and passes through, the first convex portion 36 of the filter 3 contacts the rail 51 and slides on the rail 51. As a result, the filter 3 is guided to the storage position of the storage section 23. The storage position of the storage portion 23 is a position where the filter 3 is arranged in a state where the filter 3 can cover the entire suction port 21.

Although not shown, the flat panel 30 is provided with a rail (not shown) that abuts the second convex portion 37 of the filter 3 and slides on the upper surface. It is possible to guide the storage position more accurately.

Further, in the example shown in FIG. 6, the filter 3 is inserted into the suction port 40 while the filter 3 is in contact with the surface 20a of the panel base 20, but the filter 3 does not contact the surface 20a of the panel base 20. It can also be inserted into the suction port 40. Also in this case, the first convex portion 36 of the filter 3 contacts the rail 51 and slides on the rail 51. As a result, the filter 3 is guided to the storage position of the storage section 23.

As shown in FIG. 7, when the filter 3 inserted from the suction port 40 reaches the storage position of the storage section 23, one end 33a of the filter 3 abuts against the side surface 24a of the engaging section 24, so that the insertion direction of the filter 3 is increased. To stop. Therefore, the filter 3 stops at the storage position of the storage portion 23, and the filter 3 is prevented from passing the storage position of the storage portion 23.

Further, when one end 33a of the filter 3 hits the side surface 24a of the one engaging portion 24, the other end 33b of the filter 3 comes to a position facing the side surface 24a of the other engaging portion 24. As a result, the one end portion 33a and the other end portion 33b of the filter 3 are sandwiched between the side surface 24a of the one engaging portion 24 and the side surface 24a of the other engaging portion 24, and the filter 3 is at the storage position of the storage portion 23. Retained. The pair of engaging portions 24 are configured to contact the one end 33a and the other end 33b of the filter 3, respectively, but are configured to face at least one of the one end 33a and the other end 33b with a gap.
