The present invention relates to a buckle device. The buckle device includes a strap part having gear teeth that are inclined in one direction and a buckle part interlocked with the gear teeth of the strap part in stages to move or hold the strap part. The buckle part includes a holder guiding the movement of the strap part, a catcher coupled to the holder and having an uneven part interlocked with the gear teeth of the strap part, and a lever coupled to an upper portion of the catcher. The lever, and the catcher are coupled to the holder by using one coupling pin so that the lever and the catcher are axially rotatable, and only the lever rotates within a preset rotation angle. The buckle device is especially used for a helmet for a bicycle and a motorcycle or the like, and a buckle is not separated from an adjusting band to secure safety even if an external impact is applied. Furthermore, when a user separates the buckle from the adjusting band, the buckle may be simply separated to improve user convenience. |
