< Topic >After the small animal invaded from the open part, the capture vessel of the small animal which makes open part closing of the door body which accompanies small animal invasion in the capture vessel which captures the small animal by the fact that the open part is closed with the door body, smooth is offered.SolutionsEngaging in the door body 3 which opens and closes the open part 2of a capture vessel 1, and the door body the person in charge union inside 6 which maintains the door body in open attitude of the open part and the capture vessel the movable body it has with the connected wire 7 which connects with 5 which top and bottom motion unrestrictedly is installed and the movable body and person in charge union, the door body falling by the fact that person in charge union does the engagement cancellation of the door body, attendant upon the movement of the movable body in the capture vessel of the small animal where the open part is closed, as for person in charge union, point 6a to be low in the inclined attitude where the basic end 6b is highIt was something which is engaged in the door body, at the same time, the description above receiving the prudence of the door body by the fact that it engages, point side lower moving basic end side the upper moving way in order to catch with the first and second receiving body 15 which, provides the power which it does on the respective frame side and 16 it constituted.< Selective figure >Figure 1【課題】開口部から小動物が侵入した後に、開口部を戸体で閉鎖することで小動物を捕獲する捕獲器において、小動物侵入に伴う戸体の開口部閉鎖をスムーズにした小動物の捕獲器を提供する。【解決手段】捕獲器1の開口部2aを開閉する戸体3と、戸体に係合して戸体を開口部の開放姿勢に維持する係合体6と、捕獲器内に上下動自在に取付けられる可動体5と、可動体と係合体とを連結する連結ワイヤ7とを備え、可動体の移動に伴い係合体が戸体との係合解除をすることで戸体が落下して開口部が閉鎖される小動物の捕獲器において、係合体は、先端部6aが低く基端部6bが高い傾斜姿勢で戸体に係合するものであり、かつ、前記係合することで戸体の自重を受けて先端部側が下動し基端部側が上動しようとする力をそれぞれ筐体側に設けた第一、第二の受け体15、16で受け止めるよう構成した。【選択図】図1
