The annular seat is composed of a cylinder and a plurality of fins radially disposed on an outer surface of the cylinder, in which each of the fins has an engagement protrusion. The frame is formed with a flange. The frame is assembled with the annular seat by engaging the flange with the engagement protrusion, and the engagement protrusion is deformed by the flange to fasten each other. |
