<p>A buckle which is an insertion type, wherein looseness between a buckle main body and an insertion body is eliminated and generation of impact sound or vibration sound is prevented. In a resin buckle including the buckle main body (1) formed of a housing (20) and the insertion body (2) having insertion leg portions (31) on both sides, a concave guide groove (5) is provided in a longitudinal direction of a center of an inner face of each of an upper face plate (21) and a lower face plate (22) of the housing (20) of the buckle main body (1), while a guide lever (6) which can be inserted into the guide groove (5) provided in the housing (20) is provided in a protruded form in a center of a proximal lever (30) of the insertion body (2). A sliding contact portion (8) which is elevated to make pressure contact with an opposing face is provided in part of the guide groove (5) or the guide lever (6), or sliding contact portions are provided in part of both the guide groove (5) and the guide lever (6), thereby preventing the buckle from being loose when the guide lever (6) is inserted into the guide groove (5).
