Abstract
A buckle device of the type into which a tongue plate is inserted and engaged therewith. The buckle device is equipped with a lever member having a first and a second end as well as a middle section. The first end of the lever member is engaged with a locking member, which is to be engaged with the inserted tongue plate to prevent it from being extracted from the buckle device. When the second end of the lever member is depressed, the lever member is displaced, using its middle section as the fulcrum, to release the engagement between the buckle device and the tongue plate. This lever member is equipped with a displacement section for displacing the fulcrum from the side of the first end to that of the second end when the second end is depressed. Thus, when the second end is depressed, the fulcrum of the lever member is displaced toward the second end, thereby gradually diminishing the lever ratio of the lever member.
