Embodiment Construction
[0010] An embodiment of the present invention will be described below with reference to the accompanying drawings. A solenoid valve according to an embodiment of the present invention is shown in FIG. 1 . According to this embodiment, the solenoid valve is correspondingly a linear solenoid valve for a hydraulic control device which can realize feedback control.
[0011] As shown in FIG. 1 , a coil 14 wound on a bobbin 13 made of resin is housed in a case 11 . A connector 12 made of resin is fixed to the first end of the housing 11 . The connector 12 is electrically connected to the coil 14 and is integral with a terminal 26 for energizing the coil 14 . A stepped magnetic attraction portion 11 a whose wall becomes thinner is formed at the second end of the housing 11 .
[0012] A cylindrical front end yoke (ie, serving as a fixed iron core) 16 is built in the bobbin 13 and has a flange 16a at its first end on the terminal 26 side. An annular rear end yoke 17 is integrally p...
