Abstract
A stationary core has a press fitting portion and is secured to an inner peripheral wall of a tubular member by press fitting, so that an outer peripheral wall of the press fitting portion of the stationary core is engaged with the inner peripheral wall of the tubular member, and a radial space is formed upstream of the press fitting portion of the stationary core between the stationary core and the tubular member. The stationary core can have a tapered annular outer surface section, which is arranged in an outer peripheral wall of a downstream end portion of the stationary core and is tapered toward a downstream end of the stationary core at a taper angle of 2 to 60 degrees to have a reduced outer diameter.
