Title:
POWER UNIT FOR VEHICLE SLIDING DOOR
Document Type and Number:
Japanese Patent JP3694494
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power unit for a vehicle sliding door, which is equipped with a rational clutch mechanism as a combination of a mechanical clutch mechanism and an electromagnetic clutch mechanism.
SOLUTION: The power unit includes a wheel 26 driven for rotation around a spindle 28 by the power of a motor 24, a fixed gear body 69 supported by the spindle 28, and a clutch 31 for transferring the rotation of the wheel 26 to the fixed gear body 69. The clutch 31 is comprised of a movable gear body 65, an armature 61, and a magnet coil section 60. The movable gear body 65 is always rotated together with the wheel 26, and operated so as to engage with the fixed gear body 69 when moved in a predetermined direction and to disengage from the fixed gear body 69 when moved in a direction opposite to the predetermined location. The armature 61 presses the movable gear body 65 in the predetermined direction when rotated relatively with respect to the movable gear body 65. The magnet coil section 60 applies braking resistance to the armature 61 by attracting the armature 61 by a magnetic force, to thereby inhibit corotation between the armature 61 and the movable gear body 65.
