<p>In an electromagnetic valve (1), a solenoid (3) includes a cylindrical bobbin (40), an electromagnetic coil (42) wound around the bobbin (40), a yoke (44) that surrounds the electromagnetic coil (42), a fixed iron core (46) that is fixed, coaxially with the bobbin (40), to the yoke (44), and a movable iron core (48) arranged counter to the fixed iron core (46) inside the bobbin (40) in a direction of axis line. The movable iron core (48) including a first iron core (60) that is inserted into the bobbin (40) such that the first iron core (60) is displaceable in the direction of axis line, and a second iron core (62) formed integrally with the first iron core (60) in a position opposite to the fixed iron core (46), the second iron core (62) being arranged counter to an end surface of the yoke (44) outside the bobbin (40) in the direction of axis line.</p> |
