To provide a buckle that increases a product of a distance from a rotational shaft to a gravity center position of an inertial lever and mass, and can suppress a cost while reliably preventing disengagement of a tongue and the buckle due to inertial force.SOLUTION: A buckle 1 includes: a latch member 3 that engages with a tongue 2 and latches the tongue 2; an operation button 12 for releasing the latch of the tongue 2 by the latch member 3; a base 13 that rotatably supports the latch member 3; and a lever 18 that is rotatably supported by the base 13 and contacts the operation button 12 to prevent a movement of the operation button 12 in a release direction. The lever 18 comprises: a rotational shaft 18a that fits into a groove formed in the base 13; a pin 18c that contacts the operation button 12; and a weight part 18b in which a gravity center of the lever 12 is located. The weight part 18b includes a metal member 18m. A portion surrounding the metal member 18m of the weight part 18b, the rotational shaft 18a, and the pin 18c contain a resin.SELECTED DRAWING: Figure 1

    【課題】慣性レバーの回転軸から重心位置までの距離と質量との積を大きくし、慣性力によるタングとバックルとの解離を確実に防止しつつ、コストを抑えることができるバックルを提供する。【解決手段】バックル1は、トング2に係止してトング2をラッチするラッチ部材3と、ラッチ部材3によるトング2のラッチを解除するための操作ボタン12と、ラッチ部材3を回動可能に支持するベース13と、ベース13に回動可能に支持され、操作ボタン12に当接することで操作ボタン12の解除方向の移動を阻止するレバー18と、を備える。レバー18は、ベース13に形成された溝に嵌合する回動軸18aと、操作ボタン12に当接するピン18cと、レバー12の重心が位置する錘部18bと、を有する。錘部18bは金属部材18mを含み、錘部18bのうち金属部材18mを囲む部分、回動軸18a及びピン18cは樹脂を含む。【選択図】図1
