PROBLEM TO BE SOLVED: To provide a locking tongue capable of stopping the retraction (passage) of a shoulder belt to the side of a waist belt in a very short time.SOLUTION: A locking tongue comprises: a tongue body including a main wall having clamping parts facing each other in a seat belt insertion hole and a contact parts and a pair of side walls; a lock member, actuated by seat belt tension to clamp the seat belt with the clamp parts, having a claw part coming in contact with the contact part of the main wall in the seat belt insertion hole, supported by a pair of side walls, so as to be movable between a standby position and an actuation position where the penetration amount of the claw part into the seat belt insertion hole increases more than at that position, and to be rotatable between a first condition that the claw part comes in contact with the contact part and a second condition that the claw part leaves the contact part; and an energization member that energizes the lock member in a direction of movement from the actuation position to the standby position, and in a direction of rotation from the second condition to the first condition under an energization force larger than in the movement.SELECTED DRAWING: Figure 4

    【課題】肩ベルトの腰ベルト側への引き込み(通過)を極めて短い時間で停止することができるロッキングタングを提供する。【解決手段】ロッキングタングは、シートベルト挿通孔の内部で互いに対向する挟持部および当接部を有する主壁および一対の側壁を含むタング本体と、シートベルトの張力によって作動して主壁の挟持部との間でシートベルトを挟持するロック部材であって、シートベルト挿通孔内で主壁の当接部に当接する爪部を有し、待機位置とこれよりもシートベルト挿通孔内への爪部の侵入量が増大する作動位置との間で移動可能に、かつ、爪部が当接部と当接する第1状態と、爪部が当接部から離間する第2状態との間で回転可能に、一対の側壁に支持されたロック部材と、ロック部材を作動位置から待機位置に移動する方向に付勢するとともに、それよりも大きな付勢力でロック部材を第2状態から第1状態へ回転する方向に付勢する付勢部材と、を備える。【選択図】図4
