A buckle device has a tongue member, a base member, a latch member mounted on the base member so as to be capable of assuming an engaging position in which the latch member is engageable with the tongue member and a non-engaging position in which the latch member is not engageable with the tongue member, and an operating member capable of assuming an operative position in which it brings the latch member to the non-engaging position and a non-operative position in which the latch member can assume the engaging position. The latch member has a first engaging portion and a second engaging portion, and the operating member has a first acting portion and a second acting portion. When the latch member is in the engaging position and the operating member is being brought from the non-operative position to the operative position, the first acting portion of the operating member is first engaged with the first engaging portion of the latch member to move the latch member by a set amount from the engaging position toward the non-engaging position and subsequently, the second acting portion of the operating member is engaged with the second engaging portion of the latch member to bring the latch member to the non-engaging position.
