Abstract
A tack member, which is adapted to be joined with a button body for attachment of a button to a garment fabric, has a shank of a hollow and solid combined structure. The shank is composed of a tapering hollow end portion and a solid base portion. The hollow end portion is deformable into a balloon-like shape, radially swelled and axially compressed, as its tip end is forced against a cap of the button body on its inner side during insertion of the shank into a hollow hub of the button body, during which time the solid base portion opposes bending or other deformation.
