A lock releasing button is provided at a slide plate including a slip joint for slidably supporting a webbing for restraining an occupant to a seat. Locking of the slide plate to a center pillar is arranged to be released when the lock releasing button is pressed upward from below. Therefore, when an airbag presses to open a connecting portion between a roof lining and a pillar garnish and deploys downward at a time of collision of a vehicle, the lock releasing button is prevented from releasing the locking by being pressed by the airbag deploying downward. This prevents the situation in which the slip joint is moved downward together with the slide plate to loosen the webbing and thus a seat belt device cannot sufficiently exhibit an occupant restraining performance.
