The convex portion 532 protrudes outward from the edge portion 24 of the upper container 2, and the hole 46 and the convex portion 532 as fitting portions are provided below the edge portion 24 of the upper container 2. Thereby, even if the animal urinates near the edge portion 24 of the upper container 2, it is possible to reduce the possibility that urine will leak out to the outside of the animal toilet 1 via the fitting portion.

In the present embodiment, the convex portion 532 protrudes outward from the edge portion 53 of the lower container 5 in the left-right direction. As a result, when the outer cover 4 is assembled to the upper container 2 and the lower container 5, the position of the convex portion 532 can be easily confirmed, and the fitting state of the outer cover 4 and the lower container 5 can be more easily observed from the outside. Further, the convex portion 532 does not necessarily have to protrude outward from the edge portion 53 of the lower container 5, and may protrude at least outward from the upper container 2.

The length of the upper container 2 in the left-right direction is smaller than the length of the lower container 5 in the left-right direction at the position where the convex part 532 is provided in the front-back direction. Specifically, as shown in FIG. 3B, the outer end of the edge portion 24 of the upper container 2 is positioned closer to the inner side in the left-right direction than the outer end of the edge portion 53 of the lower container 5 by Gw. In the present embodiment, the edge portion 24 of the upper container 2 is inclined inwardly from the lower side toward the upper side in the left-right direction, and is provided by The notch portion 240 is provided at a position where the convex portion 532 is provided, so that the length of the upper container in the left-right direction is formed to be smaller than the length of the lower container 5 in the left-right direction at the position where the convex portion 532 is provided. Thereby, when the outer cover 4 is removed, it is possible to suppress the edge portion 45 of the outer cover 4 from being caught by the edge portion 24 of the upper container 2.

Further, the relationship between the length of the upper container 2 in the left-right direction and the length of the lower container 5 in the left-right direction is not necessarily limited to the above relationship, and at least the edge portion 24 of the upper container 2 may be positioned on the edge portion 53 of the lower container 5.

(Configuration of the convex portion 532 of the lower container 5)

Next, the specific shape and the like of the convex portion 532 of the lower container 5 will be described with reference to FIG. 4A.

The cross-sectional shape of the convex portion 532 is an ellipse, and the size W of the ellipse in the front-rear direction is larger than the size H in the height direction. That is, the convex portion 532 has an elliptical shape elongated in the front-rear direction. Here, in consideration of the case where the grip fitting portion (the cover side fitting portion 451) lifts the animal toilet 1 upward, the force is more concentrated on the portion in the front-rear direction of the convex portion 532. Therefore, by making the size W of the convex portion 532 in the front-rear direction large, the area for receiving the force is increased, so that the convex portion 532 can be prevented from falling out of the hole 46.

Furthermore, the curvature of the upper portion 532a of the ellipse (the convex portion 532) is greater than the curvature of the lower portion 532b. That is, the lower portion 532b is flatter than the upper portion 532a, in other words, the upper portion 532a is formed in an arc shape as compared with the lower portion 532b. Therefore, since the animal toilet 1 is lifted upward in the grip fitting portion (the cover side fitting portion 451), the curvature of the lower portion 532b where the strength is more concentrated is smaller than the curvature of the upper portion 532a, so the The contact area of the outer cover 4 is widened to be able to withstand forces evenly.

In addition, the shape of the convex portion 532 is not necessarily limited to this, and may be a shape that can be inserted into the hole 46 provided in the cover-side fitting portion 451, and has a shape capable of maintaining the fitting state of the outer cover 4 and the lower container 5. .

(Configuration of the hole 46 of the cover 4)

Next, the specific shape and the like of the hole 46 of the outer cover 4 will be described with reference to FIGS. 4A and 4B.

The hole 46 is connected to a pair of notches 47 as shown in Fig. 4A. Thereby, when the convex portion 532 is inserted into the hole 46, since the hole 46 is likely to be easily deflected, it becomes easy to insert the convex portion 532 into the hole 46. Further, the notches 47 are not necessarily required to be a pair, as long as they are connected to at least one of the notches 47, and when the projections 532 are inserted into the holes 46, the holes 46 are easily deflected. Further, the hole 46 does not necessarily have to be connected to the notch 47, and the outer cover 4 may be provided with a hole 46 at least for the insertion of the convex portion 532.

In the present embodiment, as shown in FIG. 4B, in a state in which the convex portion 532 is inserted into the hole 46, the outline of the convex portion 532 shows the outline of the face of the cat, and is disposed at one of the upper portions of the hole 46. The notch 47 will show the cat's ear. That is, the hole 46 of the outer cover 4 and the pair of notches 47 serve as the face and ears of the animal, and the convex portion 532 of the face where the animal is formed is fitted in the hole 46. Thereby, the fitting state of the hole 46 and the convex portion 532 can be recognized by the shape of the animal, and it becomes easier to confirm the fitting state of the outer cover 4 and the lower container 5. Further, when it is desired to confirm the shape of the fitted state of the outer cover 4 and the lower container 5, it is not necessary to display the shape of the animal, and it is only necessary to confirm the shape of the fitted state at a glance.

The pair of notches 47 are as shown in Fig. 4B, and the upper end 47a is positioned lower than the edge portion 24 of the upper container 2. Therefore, when the pair of notches 47 are viewed in the left-right direction in a state in which the outer cover 4 and the lower container 5 are fitted, the upper container 2 is not visible through the pair of notches 47, so that the holes are more easily recognized. 46 is fitted to the convex portion 532. In the present embodiment, it is easier to know the fitting state of the hole 46 and the convex portion 532 by merely making the upper container 2 have a different color. Further, the upper end 47a of the pair of notches 47 does not necessarily have to be positioned below the edge portion 24 of the upper container 2.
