Abstract
A combining structure for the decorating shell of a ceiling fan includes an outer shell and a decorating cover. The bottom of the outer shell has a connecting hole. The rim of the connecting hole is formed upward with at least two opposite notches. Each of the notches is bent downward with a blocking rim that gradually converges. The decorating cover has an annular shape, and is mounted on the bottom of the outer shell. The inner rim of the decorating cover is protruded upward with an inner rim wall that goes through the connecting hole of the outer shell. The outer surface of the inner rim wall is protruded outward with a protruding part for each of the notches on the outer shell. The protruding parts go through the notches and urge and position on the blocking rim at the bottom of the outer shell.
