<p>PROBLEM TO BE SOLVED: To shorten a range of a storage body required to be enhanced in strength.SOLUTION: In a pretensioner 10, a wire 42 is moved to a base end side and then moved to a tip side so that a ball 52 is sandwiched between a peripheral face of a lock hole 36A of a lock piece 36 and a peripheral face of the wire 42 and thereby the movement of the wire 42 to the tip side is locked, where when the wire 42 is moved to the base end side, the movement of the ball 52 from the lock hole 36A into a cylinder 26 is restricted by a stopper plate 28. This can restrict an inner peripheral face of the cylinder 26 from tucking the ball 52 when the wire 42 is moved to the tip side; shorten a range of a storage body 20 (a base cartridge 22, the cylinder 26 and the lock piece 36) where the ball 52 may be tucked; and shorten a range of the storage body 20 required to be enhanced in strength.</p> |
