Abstract: [Object] To effectively reduce a noise generated during engaging operation of a tongue. [Solution] A slider 13 held in a non-locking position, at which the slider 13 does not lock a latch 9, turns together with the latch 9 and moves so as to enter a space between the latch 9 and the locking pin 10 during operation of the latch 9. A front end 13a of the slider 13 comes in contact with a front end 25a4 of a damper 24 before coming in contact with a stop 11f of an operation button 11, and the slider 13 moves while compressing a damper spring 26. As a result, the movement of the slider 13 is slowed down. When the front end 13a is in contact with the stop 11f, the slider 13 is positioned in a locking position, at which the slider 13 locks the latch 9 positioned in the latching position. The slider 13 that has been slowed down comes in contact with the stop 11f, reducing the noise generated when the tongue engages with the buckle 7.
