Abstract
A push nut having a washer member and a push spring with radial blade pieces arranged like a truncated cone serves to firmly retain a shaft or rod onto a frame or chassis of an electrical appliance or the like. The push nut, comprising the washer member and the push spring connected by one or more connectors, can easily be formed in one body by cutting or punching out an elastic plate into an elementary flat plate and folding the elementary flat plate so as to place the push spring and washer member one on another. The push nut having the united push spring and washer member is easy to handle and produce.
