BLIND RIVET Abstract of the Disclosure: Disclosed is a blind rivet which comprises a tubular female member provided on the outer periphery of the upper open end with a flange and a male shank member integrally engaging the hollow portion in said female portion. Said female member is provided in the tubular wall thereof with a plurality of elongate perforations in the longitudinal di- rection and said male member is provided at the lower end of the shank portion thereof with a swollen portion in tight contact with the lower portion of said female member. An extraction of the male member out of the female member re- sults in reduction in the length of said female member and consequent expansion of the tubular wall of the member in the shape of petals, causing articles subjected to riveting to be fastened up between the petalous expansion of said female member and the flange of said female member while locking means disposed on the male member and the female member co- operate to prevent the male member from being extracted from the female member.
