Abstract: In a lift-up buckle device, a slider and a shoe move forward and a buckle is moved to a stowed position. The shoe impacts against a protruding portion at a lower portion of a damper and interferes with a housing via the lower portion of the damper.

Therefore, an amount of the impact against the slider and shoe that is absorbed by the damper may be increased by the protruding portion, and the damper may absorb the impact against the slider and shoe effectively.
