PROBLEM TO BE SOLVED: To provide a gas forcible suction device capable of mechanically and forcibly suctioning high-temperature gas such as exhaust gas of an internal combustion engine, and improving combustion efficiency, with a simple structure.SOLUTION: A gas forcible suction device has an inlet part 10, an outlet part 20 and a large-diameter intermediate part 30. In the intermediate part 30, a tapered swirl flow generation cylindrical part 40 is provided. In the swirl flow generation cylindrical part 40, a projection 421 projecting radially inward and extending in spiral shape is formed. On the inlet part side of the swirl flow generation cylindrical part 40, a plurality of outflow ports 411 having a small opening area is formed in a circumferential direction. An outlet part side end side 43e of the swirl flow generation cylindrical part 40 communicates with the outlet part 20 inwardly.SELECTED DRAWING: Figure 3 【課題】簡易な構造により、内燃機関の排気ガスの様な高温の気体を機械的に且つ強制的に吸引して、燃焼効率を向上することが出来る気体強制吸引装置の提供。【解決手段】入口部（１０）及び出口部（２０）と、大径な中間部（３０）を有し、中間部（３０）内にはテーパ状の旋回流発生筒部（４０）が設けられており、旋回流発生筒部（４０）内には半径方内方に突出して螺旋状に延在する突起（４２１）が形成され、旋回流発生筒部（４０）の入口部側には開口面積が小さい流出口（４１１）が円周方向に複数形成され、旋回流発生筒部（４０）の出口部側端部（４３ｅ）は出口部（２０）内方に連通している。【選択図】図３
