Abstract
To secure sufficient attractive force against a plunger, an overrunning clutch is arranged so that one end of a thrust spline is positioned so as to maintain a prescribed interval from the end of the plunger in the condition where the plunger is unexcited by an exciting coil and the outside periphery of the output shaft corresponding to the prescribed interval is covered by a cylinder body formed of a non-magnetic material or less permeable material.
