Abstract: A buckle includes a folding member, a buckle cover pivotably linked to the folding member, a slide plate supported slidably relative to the buckle cover in the longitudinal direction of the band, and a swing arm rotatably supported by the buckle cover. The slide plate has a plurality of groove sections provided along the longitudinal direction. The swing arm includes a base, an arm section, an engagement click, and an operation strip, and is supported rotatably in a first rotational direction in which the engagement click engages with any of the groove sections and in a second rotational direction in which the engagement click separates from the groove section. The folding member includes a protruding section that comes into contact with the operation strip to rotate the swing arm in the second rotational direction when the folding member is rotated relative to the buckle cover.
