Claim:
A method for manufacturing a fitting including a blind nut, wherein said fitting has a configuration that a fitting plate and the blind nut are integrally formed so that said fitting is utilized for hanging a TV main body on a wall, and when forming a part of a plate material serving as the fitting plate into a bag-like blind hole by drawing processing and performing tap processing to an internal diameter portion to integrally form a portion corresponding to the blind nut, a tap tool having a protrusion at an end thereof is inserted into the bag-like blind hole at a planned part of the blind nut, and then carrying out the tap processing to form a continuous thread in the blind hole, thus allowing the protrusion provided at the end of the tap tool to come into contact with an inner wall at an end of the bag-like blind hole, and forming, with a material pressed thereby, a convex shape on an outer side of the bag-like blind hole.
