<p>When a pretensioner is activated, a buckle main body 3 experiences abrupt acceleration in a direction toward webbing 173. An inertial mass body 92 of a stopper member 27 is then rotated toward a frame member 21 against an urging force of a torsion spring 29 urged through a lever member 28. Further, the lever member 28 abutting on the stopper member 27 is also rotated toward the frame member 21, making each projecting piece 88 face each abutment portion 67 of a slide button 11. Further, when the slide button 11 is slidingly moved against an urging force of a button spring 32, each abutment portion 67 makes contact with each projecting piece 88 of the lever member 28, stopping the slide movement of the slide button 11. Thus, unintentional disengagement between a latch 30 and a tongue plate 17 can be prevented.</p> |
