Vehicle door opening and closing apparatus
A vehicle door opening and closing apparatus includes: an input lever configured to rotate when door opening operation is performed on an inside door handle arranged inside a vehicle; and an output lever rotatably arranged on a base plate. By transmission of rotation of the input lever to the output lever when the input lever rotates along with the door opening operation on the inside door handle, a latch unit provided between a vehicle body and a door performs release operation to allow opening movement of the door with respect to the vehicle body. A sub plate is arranged on the base plate in a form of covering the baseplate, an input support shaft for supporting the inside door handle is rotatably arranged on the sub plate, and the input lever is arranged on the input support shaft so as to integrally rotate with the input support shaft.
1. A vehicle door opening and closing apparatus, which is an apparatus configured for installation in a door of a vehicle, the vehicle door opening and closing apparatus comprising:
a base plate having a shaft mounted thereon;
an output lever configured to rotate around the shaft and configured to, when being rotated in a predetermined direction and when the vehicle door opening and closing apparatus is installed in the door of the vehicle, set latch units provided between a vehicle body of the vehicle and the door, to a release state which allows the door to separate from the vehicle body of the vehicle;
a sub plate, including a sub cover portion, which partially covers an upper part of the base plate, and a plurality of sub leg portions, which extend toward the base plate from the sub cover portion and mount on the base plate, and configured to form a space, between the base plate and the sub plate, in which the output lever is provided;
an input support shaft configured to rotate with respect to the sub plate and to support an inside door handle arranged on an inner side of the vehicle when the vehicle door opening and closing apparatus is installed in the door of the vehicle; and
an input lever, arranged on the input support shaft, configured to rotate when a door opening operation is performed on the inside door handle when the vehicle door opening and closing apparatus is installed in the door of the vehicle, wherein
when the input lever is rotated by the door opening operation of the inside door handle when the vehicle door opening and closing apparatus is installed in the door of the vehicle, the rotation of the input lever is transmitted, via a transmission mechanism, to rotate the output lever to set the latch units to the release state.
2. The vehicle door opening and closing apparatus according to claim 1 , wherein the sub plate is installed, together with the base plate, to a panel of the door.
3. The vehicle door opening and closing apparatus according to claim 1 , wherein
the input support shaft:
has a protruding portion extending through the sub plate and between the sub plate and the base plate;
includes a shaft interlocking member that is provided on the protruding portion and integrally rotates with the input support shaft; and
rotatably supports the input lever, and
the input lever is caused to rotate integrally with the input support shaft by the shaft interlocking member being engaged with the input lever.
