  • Patent number: 11913265
    Abstract: A vehicular door device includes an inclinable lever provided at an open-side end portion of a door opening being opened and closed by a door, based on an operation of a link mechanism formed of first and second link arms, a biasing member that biases the inclinable lever and holds the inclinable lever in an erect state, and a check mechanism that engages with the inclinable lever in the erect state by movement of the door to a full opened position, and holds the door at the full opened position. The first link arm is provided at a position close to the open-side end portion of the door opening by an opening operation of the door, and the check mechanism is provided integrally with the first link arm. Then, the inclinable lever is stored in a clearance between the door and the open-side end portion of the door opening.

  • Patent number: 9422989
    Abstract: An electromagnetic clutch device includes an armature, a rotor, an electromagnet, and a silencing member. The armature is supported by a driving member so that the armature is movable in the axial direction and rotate integrally with the driving member. The rotor is arranged coaxially with the armature, rotate with respect to the armature and rotate integrally with an output member. The electromagnet presses the armature and the rotor against each other based on an electromagnetic attraction force generated when current is supplied through the electromagnet to be coupled with each other in the torque transmittable manner. The silencing member is provided on an outer circumferential portion of the armature to attenuate noise generated by the vibration of the armature in a state where the silencing member is out of contact with any member other than the armature.
