<p>A driving device includes a first rotating member (13), an armature member (15) being movable and rotatable together with, a second rotating member (17) being rotatable relative to the armature member (15), a magnetic force generating means (19) for generating a magnetic force for attracting the armature member (15) toward the second rotating member (17) in order to establish a connection between the armature member (15) and the second rotating member (17) so as to be integrally rotatable, a sensor magnet (21) fixed to the second rotating member (17), a sensor (22) provided for detecting a change of the magnetic field and a fixing member (20) formed with a first claw portion (20d) engaged with the second rotating member (17) and a second claw portion (20e) engaged with the sensor magnet (21) while being press-fitted thereto in a radial direction thereof, wherein the sensor magnet (21) is fixed to the second rotating member (17) by means of the fixing member (20).</p> |
