ABSTRACT:
A buckle includes a base frame 10, a latch plate 30, a locking wing 40 and an ejector 20. The base frame 10 is formed with a tongue insertion path 12 through which a tongue plate 2 is inserted. The latch plate 30 is pivotally supported on an upper surface of the base frame 10, having a latch pawl 33 formed at a front end and an operational arm 32 formed at a rear end, which is applied with pivoting force by the end of the tongue plate 2 when the tongue plate 2 is inserted. The locking wing 40 is structured to maintain the locked state by biasing force of a locking spring 37 between the locking wing 40 and the latch plate 30 and by an engagement between the locking wing 40 and locking pawl 33. The locking wing 40 is also structured to release the engagement between the locking wing 40 and the locking pawl 33 by a movement of a press button 52. The ejector 20 is supported slidably in the tongue insertion path 12 and biased by an ejector spring 21. By the biasing force of the ejector spring 21, the tongue plate 2 is released.
