In addition, the second connecting hole 71 is the first connecting hole 71 until the closing lever 69 is fully latched.
It is formed to be long by the angle of rotating. The first connecting hole 71 and the second connecting hole 72 extend in opposite directions from the neutral position, and are formed as elongated holes at an angle that allows the operation of each other, so that the electric circuit for moving the motor 50 causes the gear 68 to move. The operations of the close lever 69 and the open lever 70 can be controlled only by controlling the direction from the neutral position to the left and right.

The open lever 70 has a fourth connecting hole 74 connected to the second connecting hole 72 and a connecting hole 75 for a rod extending from the manual operation lever, which is connected to the lower part of the pin 73. Which of the connecting holes 74 and 75 is connected?
The open lever 70 can be selectively rotated even if a force is applied thereto. Reference numeral 76 is a rod as the first connecting means, and reference numeral 77 is a rod as the second connecting means.

According to the second embodiment, since the gear 68 and the open lever 70 can be further downsized, the door opening / closing mechanism can be made compact and the cost can be further reduced.

According to the door opening and closing mechanism for an automobile according to claim 1 of the present invention, when the gear is rotated in the forward direction, the closing lever is rotated through the first connecting means, and the protruding portion of the latch is released. The latch and the lock claw are fully latched by being pushed by the close lever, but the second connecting means is in the free state, so that the open lever does not rotate. When the gear is rotated in the reverse direction, the second connecting means and the open lever are engaged with each other, the open lever is rotated via the second connecting means, the lock claw is rotated to the unlocked position, and the latch is unlocked. However, since the first connecting means is in the free state, the closing lever does not rotate.

Therefore, by controlling the rotation of the gear in the forward and reverse directions, the rotation control of the close lever and the open lever can be performed, and one motor can perform both full latch and full latch release of the latch. You can

Further, according to the automobile lock mechanism of the second aspect of the present invention, the manual operation and the operation of the open lever using the motor and the gear can be selectively performed.

As a result, the weight of the opening / closing device in the door of the automobile can be reduced and the number of parts can be reduced.
