Abstract:
A vehicle seatbelt device includes a ratchet wheel rotatable together with a spool in an integrated manner, and an engagingly locking portion. When the spool is rotated in a drawing direction at an angular acceleration larger than a predetermined angular acceleration, the engagingly locking portion is displaced radially outwardly so as to be engagingly locked by an engagingly locked portion. Hereby, rotation of the spool in the drawing direction is locked. Here, a control rod is placed axially outward of the engagingly locking portion. The control rod is displaced in the radial direction along with movement of the locking-inhibition movable portion. Along with the displacement of the control rod, a collar member is displaced axially to a restriction position. At the restriction position, the collar member enters a rotation raceway of the engagingly locking portion so as to restrict the engagingly locking portion from being displaced radially outwardly.
