[과제] 통상시에는 안전벨트에 대하여 매끄럽게 슬라이딩 가능하게 하고, 긴급시에는 랩 벨트의 신장을 억제할 수 있는 텅을 제공한다. [해결 수단] 안전벨트 슬라이딩부(17)는 제 1 및 제 2 오목부(19, 20) 내에 형성된 소정수의 돌출부(25a, 25b, 25c, 25d)를 갖는다. 제 1 돌출부(25a)는 평면 또는 대략 평면으로 형성된 숄더 벨트측의 끝면(25a)과, 평면 또는 대략 평면으로 형성된 상기 랩 벨트측의 끝면(25a)과, 원호로 형성된 선단(25a)을 갖는다. 돌출부(25a)의 최선단과 오목부(19, 20)의 외주면(21)의 원호의 중심(26)을 연결하는 가상 직선(27)과, 숄더 벨트측의 끝면(25a)이 이루는 각도(θ)가 가상 직선(27)과, 랩 벨트측의 끝면(25a)이 이루는 각도(θ)보다 작다. 제 2 및 제 3 돌출부(25b, 25c)도 마찬가지이다.

    [Object] To provide a tongue that allows a seat belt to smoothly slide thereon at normal times and that is capable of preventing stretch of a lap belt in the event of emergency. [Solution] The seat belt sliding unit 17 includes a predetermined number of the protrusions 25a, 25b, 25c, and 25d disposed in the first and second concave portions 19 and 20. The first protrusion 25a has a flat or substantially flat end surface 25a 1 on the shoulder belt side, a flat or substantially flat end surface 25a 2 on the lap belt side, and an arc-like top end 25a 3 . An angle ¸ 1 formed by the imaginary line 27 between the topmost end of the protrusion 25a and an arc center 26 of an outer peripheral surface 21 of the concave portions 19 and 20 and the end surface 25a 1 on the shoulder belt side is less than an angle ¸ 2 formed by the imaginary line 27 and the end surface 25a 2 on the lap belt side. This also applies to the second and third protrusions 25b and 25c.
