    • Provided is a seatbelt device comprising a buckle pretensioner capable of preventing a connective member from being subject to high temperature/pressure and efficiently converting combustion gas, which provides pressure for retracting the buckle, into retractive power. A buckle pretensioner 10 (30, 40, 50, 60, 70) for retracting the buckle 11 pursuant to combustion gas pressure of powder comprises a connective member 13 connected to the buckle 11, and a retractor 12 (32, 72) for retracting the buckle 11 via the connective member 13. The connective member 13 is arranged in a position such that it is not exposed to the combustion gas.
