Claim:
A slide adjuster, comprising: a belt having engagement grooves in a form of saw teeth at one side thereof, and a buckle for receiving the belt therein in a forward direction and preventing the belt in the buckle from moving in a backward direction, wherein the buckle comprises: a buckle body having a bottom plate, a ceiling frame formed above the bottom plate, and two side plates for connecting the bottom plate and the ceiling frame to form an internal space for insertion of the belt therein; and an operating plate disposed above the bottom plate adjacent the ceiling frame, and including an engagement claw projecting toward the bottom plate from a bottom surface at one lateral end portion thereof to engage one of the engagement grooves of the belt, a pressing section provided at a side opposite to the one end portion, and a connecting shaft for connecting the operating plate between the two side plates at an intermediate point between the engagement claw and the pressed section to swing around the intermediate point as a fulcrum, and wherein the buckle body further includes restricting members projecting inwardly from the two side plates, and the operating plate includes recessed portions for receiving the restricting members therein without connecting thereto to prevent an accidental pressing force from being applied in a vertical direction to the operating plate.
