PROBLEM TO BE SOLVED: To provide a bearing housing inexpensive and high in strength against a base portion.

SOLUTION: The bearing housing 1021 is constructed integrally with the base portion 12 by outsert molding. In the center of the base portion 12, there is formed a through hole whose center is positioned at the central axis. An annular fixing portion 1023 is disposed on the upper face side of the inner circumferential edge defining this through hole and fixing portions 1024 are disposed on the lower face side thereof. The annular fixing portion 1023 is so formed that the fixing portion is in tight contact with the upper face side of the inner circumferential edge defining the through hole in the base portion 12. There are formed six fixing portions 1024. The six fixing portions are annularly arranged at equal intervals with the central axis at the center. The fixing portions 1024 are so formed that they are in tight contact with the lower face side of the inner circumferential edge defining the through hole in the base portion. That is, the base portion 12 is clamped between the annular fixing portion 1023 and the fixing portions 1024 and the base portion 12 and the bearing housing 1021 are firmly fixed together.
