"textContent": "An electromagnetic fuel injection valve includes: a valve body having a rod connected to a valve part; a movable core fitted onto the rod slidably between valve-open side and valve-closed side stoppers; a fixed core having an attracting face opposing the movable core; a valve spring urging the valve body in a valve-closing direction; and an auxiliary spring exhibiting a spring force that urges the movable core to separate from the valve-open side stopper and abut against the valve-closed side stopper when a coil is unenergized. A first curved face part is protruded from a surface, opposing the movable core, of the fixed core, and a second curved face part is provided in an outer peripheral part of a surface, opposing the movable core, of the valve-open side stopper, the first and second curved face parts each having an arcuate cross-section and being capable of abutting against the movable core.",
