PROBLEM TO BE SOLVED: To manufacture a sound deadening cover which has sound deadening effect equivalent to that of a conventional component at a remarkably low cost. SOLUTION: The medium to be compressed discharged from a discharging port is once introduced into the sound deadening cover and discharged from a sound deadening cover discharging hole 14 through a capillary. As a result of the medium to be compressed passing through the capillary, a noise reduction effect can be obtained. By adopting such a structure in which only a flange face of a main bearing is covered in manufacturing the sound deadening cover, a component can be produced by one press.
