Embodiment Construction

[0046] refer to Figures 1 to 6 Examples related to the present disclosure will be described. The driving device according to this embodiment is connected to a sliding door of a vehicle by a cable or the like, and is used to actuate the sliding door so as to open or close it.

[0047] like figure 1 As shown, the driving device of this embodiment includes a motor 1 serving as a power source, an output unit 2 assembled to the motor 1 , and a control circuit unit 3 assembled to the output unit 2 . The motor 1 is used as a driving means of this embodiment, and is actuated by a direct current (eg, a DC motor) to drive the worm 1a in rotation. The worm 1a is provided on the housing 11 of the output portion 2 so as to protrude inward.

[0048] The output part 2 includes a housing 11, a housing cover 12, a worm wheel 13, a leaf spring 14, an armature member 15, a bearing 16, a rotor 17, a rotating shaft 18, and a coil member 19 (see figure 2 ), a fixed part 20, a sensor magnet 21...

Abstract

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).

Description

technical field [0001] The present disclosure relates to an electromagnetic clutch provided on a driving device. Background technique [0002] A known drive device for a sliding door of a vehicle is disclosed in JP2000-177391A and JP2000-179233A, including an electromagnetic clutch having a first rotating member, an armature member, a second rotating member and a magnetic force generating device. The first rotating member is rotated by a motor serving as a power source, the armature member is connected to the first rotating member through a leaf spring having flexibility in the axial direction, the second rotating member is arranged to face the armature member in its axial direction, The magnetic force generating means generates a magnetic force by which the leaf spring deforms in such a manner that the armature member is press-fitted on the second rotating member to rotate integrally. [0003] Specifically, according to the driving device in JP2000-179233A, the electromagn...
