发明名称 Electromagnetic drive device and fuel injection valve using the same
摘要 An electromagnetic drive device has yokes that are magnetically connected with each other and cover an outer periphery of a coil. The coil is wound around a spool. Terminals are guided by a guiding portion of the spool and are fit to the spool. Ends of the coil are electrically connected with ends of the terminals. Protrusions are formed on both circumferential side faces of the spool. The ends of the terminals are bent toward the circumferential ends of the yoke until the ends are locked by tapered faces formed on the protrusions. Accordingly, work for bending electric connections between the coil and the terminals is facilitated, and an insulation failure between the terminals or the coil and the yoke can be prevented.
