Abstract
A structure of the decorating shell for a ceiling fan includes an outer shell and a decorating cover. The bottom of the outer shell has a connecting hole. The surrounding surface at the bottom of the outer shell has at least two opposite grooves. The decorating cover has an annular shape and is correspondingly disposed at the bottom of the outer shell. The outer rim of the decorating cover is protruded upward with hook parts to engage with the grooves. At least one elastic body is interposed between the inner rim and the outer rim of the decorating cover. When the decorating cover is mounted onto the bottom of the outer shell, the elastic body is squeezed by the outer shell and the decorating cover to urge against the surrounding surface at the bottom of the outer shell.
