ABSTRACT:
A tongue includes a tongue base which can project therefrom and a tongue face plate at the forward end thereof. A buckle includes a solenoid provided at the forward end so as to attract the tongue face plate. After the tongue base is inserted into the buckle, the tongue base is drawn deep into the buckle by the pawl portion of a long hook, rocking arms are engaged with the notched portions of the tounge base, and a latch plate comes into close contact with the claw portions of the rocking arms at the back sides of the claw portions, thereby latching the tongue base. The latch plate and the long hook are advanced and withdrawn by a pinion which is rotated by a stepper motor. When the pinion is reversely rotated, the tongue base is released from the latched state, and the tongue base is pushed out of the buckle by an ejector, thereby separating the tongue from the buckle.
