  Then, when the third end 3 of the second member 20 is pierced into the stool 50, as shown in FIG. 6A, the distal end portion 29 of the second member 20 enters the inside of the stool 50, and the stool 50 becomes the second From the opening 20 </ b> B of the third end 3 of the member 20, the inside of the second member 20 is entered. The air inside the second member 20 is pushed by the feces 50 and flows out of the holes 28. As described above, the vicinity of the third end 3 of the second member 20 is formed such that the radial inner diameter decreases from the fourth end 4 toward the third end 3. That is, the inside of the second member 20 narrows at the third end 3 and widens as it goes toward the fourth end 4. When the second member 20 is pushed toward the feces 50, the feces inside the second member 20 are pushed toward the fourth end 4 to be in a radial direction until they contact the inner surface 20E of the second member 20. It spreads outside. When a sufficient amount of feces 50 enter the inside of the second member 20, feces can be visually recognized from the holes 28.

  As shown in FIG. 6B, when the second member 20 is removed from the stool 50, the stool 50A inside the second member 20 is separated from the feces 50B outside the second member 20, and the second member 20 is removed. The feces 50 are separated from the feces 50 while being retained inside. Collection of feces 50 is performed as described above.

  Here, when the second member 20 is removed from the stool 50 when the inner diameter of the second member 20 is constant or the inner diameter increases as going from the fourth end 4 to the third end 3, the inside of the second member 20 Feces 50A may fall off. This is because the force exerted by the second member 20 on the feces 50A inside the second member 20 is mainly the frictional force between the inner surface 20E of the second member 20 and the surface of the feces 50A. If the force exerted on the feces 50A by the second member 20 is insufficient, the internal feces 50A can not be separated from the external feces 50B of the second member 20, and the internal feces 50A are pulled by the external feces 50B and the second It falls off from the member 20. Alternatively, the internal stool 50A falls from the second member 20 by the action of gravity.

  In the present embodiment, the vicinity of the third end 3 of the second member 20 is formed so that the inner diameter in the radial direction decreases from the fourth end 4 toward the third end 3. When the member 20 is pulled out, the stool 50A spread in the radial direction inside the second member 20 pulls out the second member 20 from the inner surface of the second member 20 (from the third end 3 along the axial direction Force in the direction of 4). In other words, since the second inner surface portion P2 is located outside the first inner surface portion P1, the fourth inner surface P4 is located in the axial direction of the stool 50A near the second inner surface portion P2, ie, the first inner surface portion P1. The stool 50A on the side of the end 4 receives a force in the direction of removing the second member 20 from the first inner surface portion P1. Thereby, the dropping off of the stool 50A from the second member 20 is suppressed.

  FIG. 7 shows a state in which the third end 3 of the second member 20 is inserted into the inside of the first member 10. When the third end 3 of the second member 20 is inserted into the inside of the first member 10 from the opening 10A of the second end 2 of the first member 10, the tip end portion 29 of the second member 20 contacts the film 40.
