<p>To improve handling operability of a seat belt even when a belt opening angle between a portion of the seat belt adjacent to a retractor and that adjacent to an occupant is increased, a belt guide anchor (5) has a belt insertion hole (5c) into which a seat belt (4) is fitted so as to be slidable and expanded portions (5b 1 ) and (5b 2 ) formed on surfaces of the belt guide anchor facing the interior and exterior, respectively, of the vehicle adjacent to the belt insertion hole (5c). A thin portion (5e) is formed in the expanded portion (5b 1 ) on the surface facing the interior of the vehicle at a position adjoining a part of the belt insertion hole (5c) facing the front side of the vehicle, and a thin part (5f) is formed in the expanded portion (5b 2 ) on the surface facing the exterior of the vehicle at a position adjoining a part of the belt insertion hole (5c) facing the rear side of the vehicle. With this, even when a belt opening angle ¸ is large, the seat belt (4) comes into light contact with the thin portions (5e) and (5f) in the expanded portions (5b 1 ) and (5b 2 ), respectively. Thus, the friction during drawing of the seat belt (4) is small, and the seat belt (4) can be smoothly drawn out.</p> |
