A functional belt is provided to simplify the structure and to reduce the number of parts and the cost by directly fixing one end of a belt part to a fixing bar of a buckle and forming an expansion and contraction member in a first groove formed at one end of the belt part. The functional belt with elasticity is composed of a buckle(100) having a fixing bar(120) vertically installed at one end; a belt part(200) having a first groove(220) formed at one end in the predetermined depth to cover the fixing bar by forming a bent portion(240) with bending one end toward the other end; an expansion and contraction member(300) fixed in the first groove with being separated from a bottom side(225) of the first groove at a predetermined gap and combined to the fixing bar to extend and contract the length of the belt; and a fixing unit for fixing the end of the bent portion to the belt part. |
