Abstract
A base and a stator forming a housing are joined by a stator position adjustment member. The adjustment member is a ring-shaped member having an inner diameter that is equal to the outer forms of the base and the stator, and threads opposite to each other are provided to an upper portion and a lower portion of the inner circumferential surface, along the circumferential direction. A thread for being screwed with the thread is provided, in the circumferential direction, to each of an upper portion of an outer circumferential surface of the base and a lower portion of an outer circumferential surface of an outer wall member of the stator. When the adjustment member is rotated, the base and the stator move in the direction of separating from each other or in the direction of coming close to each other.
