Abstract: A door latch device includes a latch mechanism, an inner lever having a connection lever and an actuation lever, and a lock mechanism switching between unlocked and locked state. The lock mechanism includes a connection member capable of transmitting operation of the connection lever to the actuation lever, a first rotating lever rotated by a motor to first and second working positions, a second rotating lever rotatable to a first rotation position where the connection member is moved to an unlock position and a second rotation position where the connection member is moved to a lock position, a connection spring connecting the first rotating lever and the second rotating lever while allowing relative rotation of them, and a holding spring having a biasing force stronger than a biasing force of the connection spring and holds the first rotating lever at the first and second working positions.

Abstract: A lid opening and closing device includes a base to which a receiving portion is attached, a lid capable of moving between closed and open positions, a drive mechanism including a drive source causing the lid to perform an opening operation, a first operation receiving unit receiving an opening operation and outputting a first signal, a water detection unit outputting a second signal when detecting water outside an automobile, and a control unit controlling the drive mechanism based on input states of the first and signal signals. The control unit executes the opening operation of the lid by the drive mechanism when the first signal is input while the second signal is in a non-input state, and does not execute the opening operation of the lid by the drive mechanism even when the first signal is input while the second signal is in an input state.

Abstract: In the lid opening and closing device, the rotating body at the initial position rotates to one side in the rotation direction, so that the lock member is disengaged from the first link. Further, the first link and the rotating body are provided with a differential connecting mechanism, and the differential connecting mechanism connects the rotating body and the first link to operate the link mechanism at the retracted position after the lock member is disengaged from the first link, when the rotating body is rotating. As a result, the differential connecting mechanism imparts a time difference between the two operations of the rotating body. Therefore, the lock member and the link mechanism can be operated by rotationally driving the rotating body by a single actuator.
