路ユニツト。 A larger diameter part is formed on the lower outer periphery than the part where the magnetic gap of the center pole is to be formed, and a plurality of dowels are formed on the lower surface of the inner periphery of the top plate in a diagonal manner on a concentric circle with the inner diameter of the top plate. A magnetic circuit unit characterized in that the dowel engages with the upper edge of the large diameter portion of the center pole by press-fitting the top plate to form and hold a magnetic gap.
