Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door, when a door is closed to a half-latch position, which is a half-door state, and thereafter, a motor forcibly rotates the latch to a full-latch position to close the door to a fully-closed position. The present invention relates to a vehicle door closure device that is closed up to.

[0002]

2. Description of the Related Art Conventionally, a vehicle door closure device is mounted inside a rear portion of a slide door slidably supported by a vehicle body, and when the slide door is closed,
A latch mechanism part that has a latch that engages with a striker fixed to the vehicle body to hold the sliding door in a closed state, and a latch mechanism that has a pawl that can be engaged and disengaged with the latch, and a half-latch position where the sliding door is in a half-door state When the slide door is closed, the slide door is fully closed, that is, the closure mechanism unit is forcibly closed to the full latch position.

The closure mechanism portion is pivotally attached to a vertical base portion and is rotated by a motor, and a closure lever is pivotally attached to the horizontal base portion and is connected to the sector gear via a cable. And the closing lever is rotated by the sector gear through the cable, so that the closing lever engages with the arm portion of the latch to force the latch from the half-latch position to the full-latch position. (See, for example, Japanese Patent Laid-Open No. 9-209634).

[0004]

The conventional vehicle closure device as described above has a structure in which the rotational force of the motor is transmitted from the sector gear to the close lever via the cable, and therefore, due to the extension of the cable or the like. , The transmission efficiency may decrease. Therefore, in consideration of the reduction of transmission efficiency, a motor with a large output must be adopted,
The size of the device becomes large and the cost increases.

In view of the above-mentioned problems of the prior art, the present invention is intended for vehicles in which the closure efficiency can be ensured and the closure device can be miniaturized by improving the transmission efficiency. It is intended to provide a door closure device.

[0006]

According to the present invention, the above problems can be solved as follows. (1) In a body fixed to a mounting surface of a door, a latch that can be engaged with and disengaged from a striker and a pole that prevents the latch from rotating are pivotally mounted along the mounting surface. In a vehicle door closure device configured to forcibly rotate the latch from a half-latch position that barely engages the striker to a full-latch position that completely engages the striker with a motor capable of rotating in the forward and reverse directions. The first base plate fixed to the body and orthogonal to the mounting surface is provided with the motor and a sector gear that is rotated by the motor, and is fixed to the body and is substantially flush with the mounting surface. The parallel second base plate has an engaging portion integrally formed at an end portion of the sector gear by the rotation of the sector gear. Combined is moved, providing a closing lever for rotating the latch from the half-latch position to the full latch position.

(2) In the above item (1), the engaging portion of the sector gear is bent so as to be substantially parallel to the mounting surface of the door, and the engaging portion is mounted on the close lever. It is engageable with a protrusion that faces in a direction orthogonal to the plane.
