Abstract: A buckle that is compact in a longitudinal direction and uses an unlatching force that may be effectively applied to a latch member when releasing a tongue from a buckle. The buckle is configured so that as an operation button is manipulated in the unlatching direction from a state in which a tongue and a latching portion of a latch member are latched, the slider moves so that the inclined face of a pressed portion of the slider comes in contact with the inclined face of a pressing portion of an ejector and presses the ejector. Then, the ejector is spaced from the tongue and the biasing force of an ejector spring is effectively applied to the latch member via the ejector and the slider in the unlatching direction. An unlatching force is thereby applied to the latch member so that the latch member pivots in the unlatching direction, causing release of the tongue.

Abstract: A shock-proof device disposed in a buckle includes at least a latch member for engaging a tongue so as to latch the tongue; a release button for releasing the tongue from the latch member; and an inertia lever with a rotation shaft rotatably arranged for preventing the release button from moving at least in a release direction of the release button by abutting against the release button. The shock-proof device further includes torque-difference generating mechanism for generating a torque difference between a first torque and a second torque. The first torque is applied to the inertia lever when the inertial force is applied to the release button and the inertia lever in the release direction of the release button. The second torque is applied to the inertia lever when the inertial force is applied to the release button and the inertia lever in the non-release direction of the release button.
