Claim 0:
1. A power transmission device disconnectably transmitting torque for driving a vehicle, comprising:
a rotary body arranged to receive the torque to rotate about an axis;
a clutch including a clutch member engaging with the rotary body and being axially movable, and clutch teeth connectable with the clutch member to transmit the torque;
a solenoid configured to generate a magnetic flux in response to input of electric power;
a stator coupled with the solenoid to conduct the magnetic flux, and prevented from rotation about the axis;
a rotor arranged to receive the magnetic flux from the stator and, when driven by the received magnetic flux, to create a rotational motion about the axis;
a conversion mechanism drivingly connected with the rotor to convert the rotational motion into a linear motion in a direction along the axis, the conversion mechanism including a thrust member transmitting the linear motion to the clutch member; and
a differential gear set including a pair of side gears for differentially outputting the torque,
wherein the clutch teeth are formed on one of the side gears or an inner casing supporting the differential gear set.
