  • Publication number: 20210388645
    Abstract: An actuator device includes: a meshing unit configured to mesh with and release a striker, the meshing unit including a latch; an actuator unit including a motor; an output lever configured to rotate to transmit driving force of the motor in the actuator unit to the meshing unit to drive the meshing unit; and a support member both ends of which are coupled to the meshing unit, the support member being configured to support the actuator unit, wherein the output lever is separated from the support member when viewed from an approaching/separating direction of the striker with respect to the meshing unit.

  • Patent number: 11142931
    Abstract: Provided is a vehicle door latch device capable of shortening of energization time to an electrical drive source while a moving member is restrained by abutting against a stopper portion and improvement of durability of the electrical drive source. A control unit of the door latch device controls an electric motor for driving a sector gear in a release direction based on a door operation of an operation switch, and controls to stop a power supply to the electric motor when the latch is rotated from the full-latch position to the open position and a full-latch detecting switch is activated while the moving member is brought into abutment with the stopper portion and is stopped.

  • Patent number: 9290969
    Abstract: A vehicle door latch device comprises a base member having a striker-engagement groove which a striker of a vehicle body enters; a latch pivotally mounted to the base member and engagable with the striker; a ratchet pivotally mounted to the base member to engage with the latch to prevent the latch from turning; a latch-detecting switch detecting a turning position of the latch; and a synthetic resin terminal block in which a latch conductive plate is insert-molded. The terminal block has a holding portion that can hold the latch-detecting switch with an elastic claw. The latch conductive plate has a connecting terminal exposed in the holding portion and electrically connected to the latch detecting switch.
