Abstract
A pretensioner and a seat belt device are provided. A pretensioner includes a wire connected to webbing that restrains an occupant, a piston disposed to the wire, a cylinder that slidably accommodates the piston, a gas generator that applies driving force to the piston, and a housing that integrally connects the cylinder and the gas generator. The housing includes an insertion hole that guides the wire, a communication part that is communicated with the cylinder and the insertion hole, and a gas-supply port that supplies gas generated by the gas generator to the communication part. The pretensioner includes a wire guide disposed at a boundary portion of the insertion hole and the communication part, and a holding member that is inserted into the communication part and locked to the gas-supply port, thereby to position the wire guide.
