1. A slide adjuster including a band and a buckle, the slide adjuster enabling an engagement pawl of the buckle to engage with saw-toothed engagement grooves formed along an edge of the band,
wherein the buckle includes: (i) a buckle body that has a bottom plate and a top plate facing each other and side plates connecting the bottom plate and the top plate, an interior of the buckle body serving as an insertion space, and (ii) an operating piece provided inside the buckle body which has, on one end of the operating piece, the engagement pawl which is capable of engaging with the engagement grooves of the band, the operating piece being supported by a connection shaft connecting the bottom plate and the top plate at a midpoint such that the operating piece is pivotable around the midpoint as a fulcrum, and a control piece that controls pivot of the operating piece and is provided on the buckle body, and when the band is passed through the insertion space of the buckle while the engagement pawl is engaged with one of the engagement grooves of the band to be locked, the band moves forward while the edge of the band makes contact with the engagement pawl of the operating piece and presses the one end of the operating piece upward, and the operating piece returns to an initial state in reaction to coming into contact with the control piece, so that the band can freely approach the buckle but cannot retreat. |
