<p>A seat belt buckle device is provided in which the jumping height of a counterweight is decreased and which can be reduced in size. The seat belt buckle device includes an outer case 110 into which a tongue plate is inserted, a latch member 140 that latches the tongue plate, a release button 180 that releases the latching of the tongue plate by the latch member, and a counterweight 200 that resists to the sliding of the release button. The counterweight has a first rotating shaft 202 that causes the counterweight to rotate with respect to the outer case and a second rotating shaft 204 that is engaged with a bearing groove formed in the release button and receives the force that rotates the counterweight due to the sliding of the release button. The second rotating shaft has a portion, a part of the outer circumferential surface of which is missing, with this portion being configured to come into contact with the bearing groove of the release button when the release button slides into the outer case.</p> |
