ABSTRACT:
A buckle apparatus for use in a seatbelt system for a vehicle designed to protect an occupant in an emergency situation of the vehicle includes a buckle body into which a tongue plate is inserted. A lock plate is moved in a direction orthogonal to the tongue plate inserting direction and is engaged with an opening formed in the tongue plate, and portions of the lock plate on both sides of its portion engaged with the tongue plate are supported by the buckle body, thereby reliably obtaining a sufficiently large tongue plate holding strength. When the force applied to the tongue plate such as to pull it out from the buckle apparatus is relatively small, a resilient member retains the lock plate, together with the tongue plate, in such a manner that they are separated from the engaging portions of the buckle body. When the tongue plate is to be disengaged from the buckle apparatus by operating a release button, the lock plate is slid on the resilient member, thereby allowing the tongue plate to be pulled out with a reduced operating force.
