ABSTRACT:
A buckle apparatus for use in a seatbelt system is arranged such that when a tongue plate is inserted into a buckle body, the tongue plate retaining portion of a lock plate pivotally supported on one side of the tongue plate insertion passage extends through an opening formed in the tongue plate and projects out to the other side of the insertion passage so as to engage with a subsidiary lock plate. Accordingly, the lock plate which prevents the tongue plate from being undesirably pulled out is supported by the buckle body on both sides of the tongue plate and therefore can bear a large load. To release the tongue plate, the subsidiary lock plate is pivoted so as to disengage from the lock plate, which requires only a reduced force.
