A solenoid valve includes: a cylindrical spool that has an annular groove in an outer surface and moves along an axial direction under a driving force generated by a current being applied to a solenoid part; a cylindrical sleeve that has a through-hole capable of communicating with the annular groove and houses the spool; and an urging member that urges the spool by an urging force acting in a direction opposite from a direction in which the driving force is generated. When no current is applied to the solenoid part, a part of the through-hole communicates with the annular groove. When a current is applied to the solenoid part, an area of communication between the through-hole and the annular groove increases as the spool moves under the driving force acting against the urging force.

An electromagnetic clutch apparatus includes: a rotational shaft rotatable for an input and output of a rotational driving force; a rotor integrally rotated with the rotational shaft about an axis and provided with a plurality of magnetic poles each having a first polarity and a second polarity being different from the first polarity, the first and second polarities of the magnetic poles being arranged alternately along a circumferential direction of the rotor; an armature supported to be rotatable relative to the rotor; a rotational member rotated for the one of the input and output of the rotational driving force relative to the armature; an exciting coil stored in the rotor and generating magnetic flux so that the rotor electromagnetically attracts the armature; and a magnetic flux detecting element arranged to face the magnetic poles along a direction of the axis so as to detect magnetic flux of the magnetic poles.
