To provide a three-point type seat belt device which comprises a locking tongue and of which webbing pulling-in efficiency at the time of operation of a PT mechanism is good.SOLUTION: A tongue 22 of a three-point type seat belt device S comprises: a roller 66 around which a webbing 12 is so wound as to be folded back; a rotation side holding part 68 which is so configured as to be rotated integrally with the roller 66 around a cam rotary axis AX2 which is different from a roller rotary axis AX1; a shear pin 65 which regulates rotations of the rotation side holding part 68 and the roller 66 around the cam rotary axis AX2, and is broken when a load given to the roller 66 becomes a prescribed value or more, thereby releasing regulation of said rotations; and a stationery side holding part 44 which sandwiches the webbing 12 between itself and the rotation side holding part 68 when the roller 66 and the rotation side holding part 68 are rotated around the cam rotary axis AX2.SELECTED DRAWING: Figure 6

    【課題】ロッキングタングを備えると共にPT機構作動時のウェビングの引き込み効率が良い3点式シートベルト装置を提供する。【解決手段】3点式シートベルト装置Sのタング22は、ウェビング12が折り返されるように巻き掛けられるローラ66と、ローラ回転軸AX1とは別のカム回転軸AX2を中心にローラ66と一体として回転するように構成された回転側挟持部68と、回転側挟持部68及びローラ66のカム回転軸AX2周りの回転を規制すると共に、ローラ66にかかる荷重が所定値以上になると破断して前記回転の規制を解除するシェアピン65と、ローラ66及び回転側挟持部68がカム回転軸AX2周りに回転すると、回転側挟持部68との間にウェビング12を挟持する固定側挟持部44と、を備える。【選択図】図6
