The base member includes a wire hole through which a wire is placed, with a first opening on the first surface and a second opening on the second surface. A concaved area on the second surface includes a lower slope, axially between the concaved area and the second opening on which a wiring member is arranged. The wire is connected to the wiring member, radially outside of an outer diameter of the magnet.
