A seat belt buckle device that fixes a tongue plate (102) provided at a seat belt, comprising an outer case (110) into which the tongue plate (102) is inserted, a latch member (140) that rotates in response to the insertion of the tongue plate (102) into the outer case (110) and latches the tongue plate (102), a release button (180) that releases the latching of the tongue plate (102) by the latch member (140) by sliding into the outer case (110), and a counterweight (200) that is rotated by a force received from the release button (180) and resists to the sliding of the release button (180), wherein the counterweight (200) has a first rotating shaft (202) that causes the counterweight (200) to rotate with respect to the outer case (110), and a second rotating shaft (204) that is engaged with a bearing groove (192) formed in the release button (180) and receives the force that rotates the counterweight (200) due to the sliding of the release button (180), and the second rotating shaft (204) has a portion, in which part of an outer circumferential surface of said second rotating shaft (204) is missing when compared with said second rotating shaft (204) having a round cross section, with this portion being configured to come into contact with the bearing groove (192) of the release button (180) when the release button (180) slides into the outer case (110), wherein the second rotating shaft (204) of the counterweight (200) comes into contact with the bearing groove (192) of the release button (180) by an outer circumferential surface except the portion, in which part of an outer circumferential surface of said second rotating shaft (204) is missing when compared with said second rotating shaft (204) having a round cross section, when the seat belt buckle device fixes the tongue plate (102).
