ABSTRACT:
A self-piercing nut holding device for use in association with an automatic assembling machine, the holding device including a passageway adapted to allow a punch to pass through, the passageway including a nut delivery outlet through which nuts are individually placed at the "hold" position, the passageway being provided with an elastic member in a recess produced in its defining side wall, the elastic member having a body portion and a pair of leg portions which are supple against a force acting when the elastic member holds a nut situated at the "hold" position. The suppleness of the elastic member protects same against breaking; otherwise frequent breakages would lead to frequent interruption of the automatic assembling operation.
