There is the radial direction annular groove extending in the wall of cylindrical base body side, the periphery of annulus extend in radial direction annular groove.
Described cylindrical base body includes radially split left matrix and right matrix two parts, and fan main body is arranged on a left side
After in matrix and right matrix, left matrix and the fixation of right matrix are formed by complete entirety by securing member.
Described cylindrical base body includes along the circumferential direction split upper matrix and lower substrate, and fan main body is arranged in lower substrate
Afterwards complete entirety is formed by the capping of upper matrix.
It is provided with the axial annular groove of more than two along the circumferential direction arranging, described axial direction in the side wall of described cylindrical base body
Annular groove is mutually communicated with radial direction annular groove, and described annulus is provided with the outer shroud in axial annular groove.
Described cylindrical base body is made up of matrix on polylith and lower substrate, fan main body be respectively disposed on adjacent upper matrix and
