This invention provides a fixture for an abrasive cloth paper in which a surface fastener does not have to be bonded prior to fixing of the abrasive cloth paper onto the fixture and in which hook-shaped engaging elements are disposed accurately at portions directly related to polishing by an abrasive cloth paper fastening portion of the fixture with precedence. A fixture made of synthetic resin comprises a mounting portion which is engaged with/disengaged from a base plate of a sander and a fastening portion on which an abrasive cloth paper is wound and fastened. In the fastening portion, a plurality of surface fastener engaging element rows which are parallel to a direction of winding of the abrasive cloth paper are formed integrally so as to form a fastening surface. A hollow portion is formed in the fastening portion. Consequently, a complicated work for bonding a male surface fastener to the fixture integrally is eliminated and surface fastener engaging element rows can be arbitrarily formed integrally at required portions on a surface of the fastening portion of the fixture. As a result, the fastening surface composed of the surface fastener engaging element rows can be formed accurately only at portions in which a fastening strength with respect to the abrasive cloth paper needs to be ensured, and no fastening surface FS is formed in a portion not requiring the fastening-strength, thereby leading to reduction of production cost.
