At that time, as shown in FIG. 16 (c), while the sheet mounting member 40 is inclined so as to follow the warp shape of the upper portion of the sheet mounting portion 37, the upper portion of the sheet mounting portion 37 is placed on the sheet mounting member. By sliding the sheet attachment member 40 so as to be sandwiched between the main body 41 and the elastic engagement piece 45 (see arrow D3 in FIG. 16C), the sheet attachment is performed as shown in FIG. 16D. It can be smoothly attached to the portion 37.

  On the other hand, when the sheet S is removed from the sheet attachment portion 37, it is necessary to remove the sheet attachment member 40 in the state shown in FIG. 17A from the sheet attachment portion 37. First, as shown in FIG. As shown, the sheet mounting member main body 41 and the sheet mounting member main body 41 are elastically sandwiched with respect to the upper part of the sheet mounting part 37 while tilting the posture of the sheet mounting member 40 so as to follow the warp shape of the upper part of the sheet mounting part 37. By sliding the engagement piece 45 in the pulling direction (see arrow D4 in FIG. 17 (b)), the elastic engagement piece 45 is elastically deformed, and as shown in FIG. 17 (c), a sheet attachment member 40 can be smoothly removed from the sheet attachment portion 37.

  Therefore, when the sheet is intentionally detached from the sheet attachment portion 37, the sheet can be easily removed, and the sheet can be easily replaced.

  Further, in the state where the sheet attachment member 40 is attached to the sheet attachment portion 37, the sheet attachment portion 37 and the sheet attachment member main body 41, which are formed in an approximate warpage shape, face each other with the sheet S therebetween. Since it can be made to fit, the stable attachment state can be obtained.

  Furthermore, the sheet S is sandwiched with the sheet attachment member main body 41 and the sheet engaging portion 37 is deformed by the elastic force (restoring force) of the elastic engagement piece 45 which is bent and deformed according to the thickness of the sheet attachment portion 37. Can be kept firmly attached.

  In addition, as shown in FIGS. 12A and 12B, the upper portion of the sheet S is folded back from the front side to the rear side with respect to the sheet attachment portion 37, and the urine receiving wall portion 36 in the upper portion of the sheet S is formed. Since both the portion disposed on the side and the folded portion are attached by being sandwiched between the sheet attachment portion 37 and the elastic engagement piece 45 and the sheet attachment member main body 41, the elastic engagement piece 45 and the sheet attachment member are provided. By significantly increasing the thickness of the object sandwiched between the main body 41 and the sheet S, it is possible to obtain an excellent sheet holding force by utilizing the elastic force of the elastic engagement piece 45.

  Therefore, as shown in FIG. 15B, even if the pet placed on the presser net 20 pulls the sheet S attached in a state where it is suspended along the urine receiving wall 36, the sheet is attached to the sheet attachment member. The sheet S can be kept firmly attached to the sheet attachment portion 37 without being detached from the sheet 40.

Furthermore, as shown in FIGS. 6 and 18 (a), (b), (c), (d), and (e), the pet toilet 1 has a width at the rear upper portion of the rear side wall portion 35B. Back ribs 44 are formed on both sides in the direction.
FIG. 18A is an enlarged view of one side portion in the width direction of the upper portion on the back side of the back side wall portion 35B of FIG. FIG. 18B is an enlarged view of one side portion in the width direction of the rear side upper portion of the back side wall portion 35B of FIG. 6 with the sheet S attached. 18C is an enlarged sectional view taken along the line CC in FIG. 18B, and FIG. 18D is an enlarged sectional view taken along the line DD in FIG. 18B. (E) is the EE line expanded sectional view in Drawing 18 (b).

  According to the above-described configuration, when the sheet mounting member 40 is slid in the width direction while being attached to the sheet mounting portion 37, the edge portion 47 a of the through hole 47 in the sheet mounting member main body portion 41 abuts on the back rib 44. Thus, the sliding of the sheet attachment member 40 can be restricted.

  Specifically, when the sheet attachment member 40 tries to slide to one side in the width direction, the back rib 44 disposed on one side in the width direction of the back side wall portion 35B has a width in the sheet attachment member main body 41. It abuts on the edge 47a of the through hole 47 formed on one side in the direction.

  On the other hand, when the sheet attachment member 40 is about to slide to the other side in the width direction, the back rib 44 disposed on the other side in the width direction of the back side wall 35B is the other in the width direction of the sheet attachment member main body 41. It abuts on the edge 47a of the through hole 47 formed on the side.

  In this way, by forming the back rib 44 on the back side wall portion 35B, the sheet mounting member 40 is attached to the sheet mounting portion 37, and either the one side or the other side in the width direction is selected. Even if the sheet mounting member 40 is unexpectedly slid, the sheet mounting member 40 can be regulated so as not to slide further in the width direction, so that the sheet mounting member 40 is prevented from being unexpectedly detached from the sheet mounting portion 37. Can do.

  Therefore, the sheet attachment member 40 can be maintained in a state where the sheet S is attractively attached to the sheet attachment portion 37 with good appearance.

  Further, as shown in FIGS. 18B, 18 </ b> C, 18 </ b> D, and 18 </ b> E, the folded portion of the sheet S that hangs down on the back side of the sheet attachment portion 37 is engaged by the back rib 44. At the same time, the sheet mounting member 40 can press the sheet S in a state where the sheet S is sandwiched therebetween.

  Thereby, in particular, as shown in FIG. 18 (e), the sheet S is in a state of being firmly engaged (engaged) between the back rib 44 and the sheet attachment member 40 in the width direction. Therefore, the holding force of the sheet S attached to the sheet attachment portion 37 by the sheet attachment member 40 can be remarkably improved.

  Therefore, even if the pet pulls the sheet S or the like, the sheet S interposed between the sheet mounting portion 37 and the sheet mounting member 40 does not unintentionally come out of between them, and the sheet S is attached to the sheet mounting portion 37. Can be kept firmly attached to.

  Furthermore, the pet toilet 1 described above can exhibit the following actions and effects.

  The sheet attachment member 40 is formed by continuously forming the sheet attachment member main body 41 over the entire length in the length direction of the sheet attachment member 40, and elastically rightward on each side in the length direction of the sheet attachment member main body 41. The engagement piece 45R and the left elastic engagement piece 45L are arranged.

  According to the configuration described above, the right elastic engagement piece 45R and the left elastic engagement piece 45L are engaged with the sheet attachment portion 37 with the sheet S sandwiched therebetween, whereby the right elastic engagement piece 45R is engaged. The sheet S can be attached together with the sheet attachment member main body 41 in a state of being firmly sandwiched by both the piece 45R and the left elastic engagement piece 45L.

  Furthermore, since the sheet attachment member main body 41 is continuously formed over the entire length of the sheet attachment member 40, the sheet attachment member 40 is attached to and detached from the sheet attachment portion 37. The sheet attachment member main body 41 is slid upward along the warped shape of the attachment portion 37, whereby the right elastic engagement piece 45 </ b> R and the left elastic engagement piece 45 </ b> L are respectively transferred to the sheet attachment portion 37. On the other hand, it can be easily engaged and disengaged in a lump.

  In addition, as described above, the pet toilet 1 folds the upper part of the sheet S from the front side to the back side with respect to the sheet attachment portion 37 and folds back with the portion arranged on the urine receiving wall portion 36 side. Since both are attached to the sheet attachment portion 37 together with the elastic engagement piece 45 and the sheet attachment member main body 41 (see FIG. 17A), the upper end of the sheet attachment portion 37 is attached. There is also an effect that dust or the like does not enter between the urine receiving wall portion 36 and the sheet S from the side.
