PROBLEM TO BE SOLVED: To simplify the structure of a pretensioner to facilitate assembling of the pretensioner.SOLUTION: A housing 30 formed by integrating a cylindrical part 31 with a holding part 32 is mounted on a cylinder 10. The cylindrical part 31 is fitted on an outer periphery of the cylinder 10. A gas generator 4 is held by the holding part 32 to supply a gas into the cylinder 10. The gas allows the piston 20 to move in the cylinder 10. A connection member 50 pulls a seatbelt as the piston 20 moves. A base 40 has a fitting part 41 and a presser part 42 integrated with each other, and is fixed to a body with a fixing member 3. The fitting part 41 of the base 40 is fitted on an inner periphery of the cylinder 10. The presser part 42 presses the housing 30. |
