Electromagnetic fuel injection valve

An electromagnetic fuel injection valve in which a rear end of a magnetic cylindrical body (13) is coaxially connected to a front portion of a cylindrical fixed core (23) via a non-magnetic cylindrical body (25);

• a movable core (20) of which rear end is opposed to a front end of the fixed core (23) is coaxially connected to a valve body (10) which is capable of being seated on a valve seat (8) provided at a valve seat member (14) coaxially connected to a front end of the magnetic cylindrical body (13) and which is biased to a side to be seated on the valve seat (8);
• and a coil assembly (11) formed by winding a coil (29) around a bobbin (28) is disposed to surround a rear portion of the magnetic cylindrical body (13) and the fixed core (23),
• characterized in that the bobbin (28) integrally includes:
• a cylindrical portion (28a) which surrounds the rear portion of the magnetic cylindrical body (13) and the fixed core (23);
• a pair of flange portions (28b, 28c) which protrude radially outward from opposite ends of the cylindrical portion (28a) so as to define opposite ends of the coil (29) that is wound around an outer periphery of the cylindrical portion (28a);
• and a terminal boss portion (36) which protrudes sideway from one (28b) of the flange portions (28b, 28c) that is disposed at a side opposite from the magnetic cylindrical body (13) and to which a pair of power-receiving-side connecting terminals (38) are fixed, and
• that engagement recesses (46) are respectively formed to be recessed inward on opposite sides of a portion of the terminal boss portion (36) connected to the one flange portions (28b) so that intermediate portions of a pair of coil ends (29a) extending from opposite ends of the coil (29) are passed through and engaged with the engagement recesses (46) and are electrodeposited respectively to a pair of electrode position portions (38a) provided at both the power-receiving-side connecting terminals (38).
