Patent ID: 10184530

Abstract:
An electromagnetic connection device includes an armature (4), a rotor (3), an electromagnetic coil (14), and a spring member (24) that biases the armature (4) in a direction in which the armature (4) is separated from the rotor (3). The electromagnetic connection device includes a damping member (25) mounted on the armature (4) so as to face the rotor (3). The armature (4) includes a flat portion (22) and a tubular portion (8). The damping member (25) includes a damper cover (26) including an abutment portion along the flat portion (22) and an engaging portion along the tubular portion (8), and an elastic member (27) sandwiched between the abutment portion and the flat portion (22). The damper cover (26) is put on the armature (4) from the side of the rotor (3) and movably held on the tubular portion (8). The flat portion (22) includes a concave portion (35) configured to store the abutment portion of the damper cover (26). There is provided an electromagnetic connection device capable of obtaining a high damping effect and raising the productivity while preventing the elastic member from being exposed to a friction surface.
