Abstract
A first of two members which are joined in a manner to undergo synchronous rotation is formed with a aperture which has a flower-like shape and which has a periphery which is essentially free of sharply angled portions. A hollow projection formed on one end of a shaft is forced into the aperture and then punched to assume the shape of the aperture and to caulk the two members together.
