To provide a device for preventing the diffusion of odor when disposing excrement.
An enclosure body 1 covering an appropriate area from the neck part to the leg parts of a care-receiver is used. The enclosure body prevents the diffusion of the odor of the excrement by using a transparent resin sheet 3 and an airtight fiber fabric 4 for a frame body of a three-dimensional structure. One face of the enclosure body is provided with a discharge mechanism 20 using insertion holes 7 for inserting the hands and arms of a care-giver, an air intake hole 11, an exhaust hole for exhausting odor body and a pump. In each of leg-part holes 9, the sheet is divided to open a part and, after being wound around a leg part, is closed using a hook-and-loop fastener.
