To satisfy both of prevention of wearing feeling deterioration when an adult wears a seat belt and prevention of separation of the seat belt from the shoulder when a child wears the seat belt during a collision without adding expensive components and separately performing a manual operation.SOLUTION: A seat belt 40 via a belt guide 10 from a retractor 30 extends obliquely downward from the shoulders of occupants (an adult P1 and children P2) and restrains the occupants. The belt guide 10 has an inside side wall section 14 which regulates the seat belt 40 from being displaced toward the occupant side. The belt guide 10 can be displaced from a normal position (a position shown by a solid line in Fig. 3) toward a position closer to the occupants (a position shown by a one-point chain line in Fig. 3) by a slide mechanism ST and is located at a normal position by a spring 53, for instance, during a normal time. The belt guide 10 receives component force directing to the occupant side of tensile force of pretension by the retractor 30 and is displaced toward the position closer to the occupants.SELECTED DRAWING: Figure 3

    【課題】高価な部品の追加や別途マニュアル操作を行うことなく、大人が装着したときの装着感悪化の防止と子供が装着したときの衝突時におけるシートベルトの肩外れ防止とを共に満足させる。【解決手段】リトラクタ30からベルトガイド10を経由したシートベルト40が乗員(大人P1、子供P2)の肩部から斜め下方へと延びて乗員を拘束する。ベルトガイド10は、シートベルト40が乗員側へ向けて変位するのを規制する内側側壁部14を有する。ベルトガイド10は、スライド機構STによって、通常位置(図3実線で示す位置)から乗員寄り位置(図3一点鎖線で示す位置)へ向けて変位可能とされ、通常時は例えばスプリング53によって通常位置とされる。ベルトガイド10は、リトラクタ30によるプリテンションの引張力のうち乗員側に向かう分力を受けて、乗員寄り位置へ向けて変位される。【選択図】 図3
