Abstract
A push nut formed of an annular rim and an elastic prong member having a fragile portion capable of being easily bent with a pushing force can be easily engaged with a rod-shaped article such as a shaft, consequently to firmly secure the rod-shaped article onto a frame of an electrical appliance or the like. The fragile portion of the prong member is formed by one or more slots, thin-walled parts, or grooves. The push nut engaged with the rod-shaped article can easily be disengaged by pressing down the prong member with a cylindrical tool to bend the prong member at the fragile portion, so that the rod-shaped article can be freed from the frame of the electrical appliance with little damage and can be reused effectively.
