摘要： In a pretensioner main body, a cylindrical space and a gas introducing space connecting with one end of the cylindrical space are formed, and a blocking end portion including a first through hole portion is provided to block the gas introducing space. A piston is movable within the cylindrical space, and a coupling member coupled to the piston is guided to the outside from the gas introducing space through the first through hole portion. An elastic seal member is provided on the inner surface side of the blocking end portion and includes a second through hole portion allowing the coupling member to pass therethrough. A gas buffer member is provided at such a position as to sandwich the elastic seal member between the blocking end portion and itself, where a third through hole portion having a shape and a size corresponding to the shape and size of the cross-section of the coupling member is formed.

摘要： A winding drum with a webbing wound thereon has one axial end rotatably supported by one sidewall section of a housing, and a shaft section raised from the other axial end is rotatably supported through a cover member mounted on the outer end of the other sidewall section of the housing. The housing has an opening formed in the other sidewall section through which a ratchet gear is inserted with gap therebetween, the ratchet gear being formed on the outer peripheral edge of the winding drum at the other axial end side thereof; and inner teeth formed on the inner peripheral edge of the opening. When pretensioner mechanism is activated and tensile force greater than predetermined level acts on the webbing, the cover member is plastically deformed through the shaft section and locks the ratchet gear into engaged state wherein the ratchet gear is engaged with the inner teeth.

摘要： It is aimed to provide a seatbelt retractor whose manufacturing cost is reduced. A retractor includes a windup drum that winds webbing and a pretensioner unit that causes the windup drum to rotate in a windup direction of the webbing. The pretensioner unit includes a pinion gear configured to rotate in association with the windup drum, a piston that includes a rack for meshing with the pinion gear (165) and causes the windup drum to rotate in the windup direction through the pinion gear, a tubular cylinder that has a circular cross-section and movably holds the piston, and a drive mechanism that drives the piston. The piston further includes, on a rear surface side of the rack, a contact surface configured to come into contact with an inner wall of the cylinder, and the cylinder has such a tube length as not to expose the contact portion in a movable range of the piston.
