<p>PROBLEM TO BE SOLVED: To provide a buckle device allowing various detections based on pulling of a webbing belt, for example, in mounting a child seat. SOLUTION: In the buckle device 10, a buckle body 26 is connected movably in a predetermined range to an anchor plate 22 in the longitudinal direction of long holes 102 formed in the anchor plate 22, and energized to an insert direction side (anchor plate 22 side) with an energizing force to an extension spring 108. The webbing belt is pulled out by a distance required for fixing the child seat, and thus the buckle body 26 is moved against the extension spring 108 with the energizing force for winding the webbing belt. Thus, a pressing force for pressing a force sensor 114 disposed in the buckle body 26 by a support piece 110 of the anchor plate 22 decreases, and detection of the decrease in the pressing force allows detection whether the child seat is mounted or not.</p> |
