At the time of the mounting operation, the deodorizing cartridge 12 is mounted from the front of the apparatus main body 1 and obliquely below by the mounting wall surface 14a, the locking projections 15 and the contact projections 16. Mounting can, deodorizing cartridge 12 and the engaging protrusion 15 by the abutment projection 16 is attached to the main body 1 without falling, it is retained. The locking projections 15 and the contact projections 16 do not need to be continuously connected in the cross section of the ventilation path 10, and when they are formed by a molding die, they may be ribs in the mold structure of the molded product. It is desirable because the product cost can be reduced.

Further, even if the fan 11 is vertically mounted on the apparatus main body 1 upstream of the odor inlet of the deodorizing cartridge 12, the exhaust outlet of the fan 11 and the odor inlet of the deodorizing cartridge 12 are substantially parallel. They can be arranged and ventilation resistance does not increase. Further, the vertical distance between the upper end of the fan 11 and the lower end of the deodorizing cartridge 12 is also reduced, so that a large space is not required even when incorporated in the apparatus main body 1. Therefore, the deodorizing cartridge 12 and the fan 11 can be incorporated in a limited space such as below the operating means 7, and the device body 1 of the toilet seat device with deodorizing can be made compact. The inclination angle of the deodorizing cartridge 12 is preferably close to horizontal in consideration of compactness. However, since it is conceivable that the cartridge 12 rotates and falls around the locking projection 15, an inclination angle of about 30 ° to 60 ° is preferable. good. Regarding the size of the inclined projections 15, regardless of the shape, if the size is such that the mounting of the deodorizing cartridge 12 is not hindered and the shape does not easily drop after the mounting of the deodorizing cartridge 12, the press-fitting is performed when the deodorizing cartridge 12 is mounted. And a structure elastically fitted to the deodorizing cartridge 12 may be used. Regarding the contact protrusion 16,
Any shape may be used as long as the size is such that the mounting of the deodorizing cartridge 12 is not hindered, and it does not easily drop after the deodorizing cartridge 12 is mounted, and the device main body front mounting wall surface 14a inclined downward toward the front side of the device main body 1. When the deodorizing cartridge 12 is mounted, the contact projection 16 and the apparatus main body front mounting wall surface 14a inclined downward toward the front side of the apparatus main body 1 when the deodorizing cartridge 12 is mounted.
Since the mounting direction of the deodorizing cartridge 12 is limited, the mounting and removing work of the deodorizing cartridge 12 is easy.

Here, the type of the deodorizing agent enclosed in the deodorizing cartridge may be either a activated carbon type or a catalytic type such as manganese oxide, or a combination thereof. Further, if the strength of the deodorant does not cause a problem in direct mounting to the deodorizing cartridge mounting portion, there is no need to cover the deodorizing cartridge with a cylinder or the like.
