PROBLEM TO BE SOLVED: To provide an animal trapping trap device which can be installed more easily and in a shorter time without making a hole in the ground while making it lighter. SOLUTION: A frame mount 1, wire flip-up frames 7 and 8, a wire 19 having a bundling ring 20 formed at one end, a biasing means for biasing the bundling ring 20 to reduce the diameter, and a tread plate 6. A pair of wire flip-up frames 7 and 8 are rotatably connected to the frame mount 1, and a wire bundling ring 20 is attached to the outer circumference of the wire flip-up frames 7 and 8 so that the animal can step on the tread plate 6. When stepping on, the step board 6 is released from the pair of wire flip-up frames 7 and 8 to release the diameter reducing force, and the wire bundling ring 20 and the wire flip-up frames 7 and 8 bounce upward to raise the animal's foot. Tightening trap device for capturing animals.
