(Fifth Embodiment)
Next, the local cleaning device according to the fifth embodiment of the present invention will be described.

As shown in FIG. 8, in the fifth embodiment, the shutter 10 has a protrusion 92 projecting rearward from the upper end of the rear surface 62. The protrusion 92 is formed so as to be insertable into a recess (locking recess) 94 formed in the upper part of the shutter receiver 40. The recess 94 has a depth and shape similar to the protrusion amount and shape of the protrusion 92.

According to the local cleaning device of the fifth embodiment, the protrusion 92 fits in the recess 94, so that the shutter 10 can be attached to the shutter base 30 in a predetermined orientation and posture. Even if the user tries to attach the shutter 10 to the shutter base 30 with the shutter 10 in the wrong direction, that is, with the protrusion 92 facing the lower side of the shutter 10, the protrusion 92 hits the lower flat surface 96 of the shutter receiver 40. , Cannot be installed. As a result, it is possible to prevent erroneous assembly of the shutter 10 and prevent damage to the shutter 10 and malfunction of the operation of the shutter 10.

In the fifth embodiment, it has been described that the protrusion 92 is provided at the upper end of the rear surface 62 and the recess 94 is formed at the upper portion of the shutter receiver 40, but the protrusion 92 and the recess are formed in the left-right direction T1 and the vertical direction T3. The positions of the protrusions 92 and the recesses 94 are not limited as long as the positions of the 94s overlap each other. For example, a protrusion 92 may be provided at the lower end of the rear surface 62, and a recess 94 may be formed at the lower end of the shutter receiver 40.

Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the above-described embodiment. The present invention can be modified within the scope of the gist of the present invention described in the claims.
