Connecting the sample gas suction pump 1 and the leakage gas detection unit 2 to the sample gas suction tool 3, and causing the sample gas suction tool 3 to levitate and follow the road surface R. A leakage gas detection device from an underground pipe is provided with a first seal member 5 that can be freely switched between an inspection state and a stationary inspection state in which the sample gas inhalation space 4 is formed in close contact with the road surface R, This leakage gas detection device from an underground pipe is provided with a second seal member 6 that is brought into contact with the road surface R to form a sample gas intake space 4' in a moving inspection state. 2. The leakage gas detection device from an underground pipe according to claim 1, wherein the first seal member 5 is constituted by an elastic cylinder whose surface in close contact with the road surface R is wide. . 3. The leak gas detection device from an underground pipe according to claim 1 or 2, wherein the second seal member 6 is disposed outside the first seal member 5. 4. The leak gas detection device from an underground pipe according to any one of claims 1 to 3, wherein the second seal member 6 is a flexible sheet. 5. Any one of claims 1 to 4, wherein the sample gas suction pump 1 is configured to have a stronger suction force in the stationary inspection state than in the moving inspection state. A leakage gas detection device from an underground pipe as described in the above. 6. Utility model registration claim 1, wherein the leaked gas is liquefied petroleum gas, and the leaked gas detection section 2 is a hot wire type semiconductor saturated hydrocarbon selective gas sensor made of a sintered tin oxide body. A leakage gas detection device from an underground pipe according to any one of items 1 to 5.
