Title:
ELECTROMAGNETIC COUPLING DEVICE
Document Type and Number:
Japanese Patent JP2019148292
Kind Code:
A
Abstract:
To manufacture at low cost an electromagnetic coupling device capable of reducing impact noise in both cases in which an armature 14 is magnetically attracted to a rotor 2 and released.SOLUTION: An electromagnetic coupling device comprises: an electromagnetic coil 13; a rotor 2 (attraction member) that magnetic flux passes through; a hub 15 (rotary member) which is arranged nearby the attraction member; an armature 14 which is supported by the hub 15 through a leaf spring 22, and moves in an axial direction of the hub 15 against spring force of the leaf spring 22 as the electromagnetic coil 13 is powered to be magnetically attracted to the hub 2; and a vibration absorbing member 41 fixed to a region (arm part 31), moving as the armature 14 moves, of the leaf spring 22. The vibration absorbing member 41 has a stopper part 42 coming into contact with the hub 15 from the side of the armature 14 and a damper part 43 coming into contact with the armature 14.SELECTED DRAWING: Figure 2
