  However, in the vehicle door latch operating device described in Patent Document 1, when the lock lever and the linking member are in the locked position, the operation of the door opening operating means and the power source is performed in a superimposed manner. A so-called panic state occurs in which the lock lever and the linking member remain in the locked position despite the unlocking operation. This is because when the linkage member is in the locked position, when the handle lever is released by the operation of the opening operation means, the linkage member relatively moves in the cam hole and unlocks from the locked position. This is because the cam hole is engaged so that the movement to the position is prevented. Therefore, when a panic condition occurs, the lock lever remains in the locked position even if the door opening operation means is returned to the position before the operation, so that it is necessary to re-operate the power source and the operation becomes troublesome. The problem occurs.

  In view of the above-described conventional problems, the present invention eliminates the problems when the door opening operation means and the power source are operated in a superimposed manner, and operates the vehicle door latch with improved operability. The object is to provide a device.

According to the present invention, the above problem is solved as follows.

A first lever that is pivotally supported by two axes and that is actuated by a power source to move the first lever to an unlocked position and a second lever that can also be moved to a locked position; the provided between two levers, the first lever to the second lever, and urging means for urging the unlocking direction, one end The second lever is supported on the second lever by the second lever so that the second lever is held at the unlocked position and the locked position, and the holding force is larger than the biasing force of the biasing means. A turnover spring that is set, and an interlocking member that is linked to the first lever and that can be moved to an unlocked position that allows the release operation of the handle lever to be transmitted to the release lever, and a locked position that cannot be transmitted. When the handle lever is released when the first and second levers and the linking member are in the locked position, the release lever does not operate in the release direction and stops at the standby position. In this state, the power source is unlocked. When the locking operation is performed, the first lever and the linking member remain in the locked position, and only the second lever is Tsu moved from click position to the unlocked position, in a state where the turnover spring holds the said second lever in the unlocked position, when the handle lever returns to the standby position before releasing operation, the first lever and the The linkage member can be moved from the locked position to the unlocked position by the biasing force of the biasing means.

( 2 ) In the above item (1 ) , an actuator that constitutes the power source is provided on the base plate, and the actuator has a motor and an output lever that can be moved to an unlock position and a lock position by the power of the motor, The output lever is connected to the second lever.

According to the present invention, the following effects can be obtained.
Even if the operation of the opening operation means and the power source is performed in a superimposed manner, the lock lever and the linking member can be moved to the unlock position by returning the opening operation means to the position before the operation, The operability can be improved.
