<P>PROBLEM TO BE SOLVED: To provide a pretensioner mechanism in which gas in a cylinder member can be discharged before the cylinder member and a moving member can be separated from each other when the gas is supplied into the cylinder member and, thereafter, the cylindrical member and the moving member are disassembled. <P>SOLUTION: In the pretensioner mechanism 36, a hammering force is applied to a rupture device by a hammer while the sharp tip of the rupture device is inserted into a recessed part 78 of a cylinder 66, thereby, the rupture device breaks the recessed part 78 position of the cylinder 66 and the interior of the cylinder 66 is made to be openable via the recessed part 78 position. Therefore, the recessed part 78 position of the cylinder 66 is broken before the cylinder 66 and the piston 88 are made to be openable, thereby, the interior of the cylinder 66 can be opened via the recessed part 78 position and the gas in the cylinder 66 can be discharged via the recessed part 78 position. <P>COPYRIGHT: (C)2013,JPO&INPIT |
