塞拉门装置
摘要：
本发明提供一种能够利用使向车辆的前后方向的力作用于车门的车门驱动机构来进行开闭动作和塞拉动作而且还能够应用于单扇推拉式车门的小型的塞拉门装置。滑动基座（12）以能够相对于固定基座（11）沿车宽方向滑动移动的方式设置。用于借助连结部（19）使1扇车门（104）沿车辆的前后方向移动的车门驱动机构（13）设于滑动基座（12），该车门驱动机构（13）包括：具有电动马达（21）的驱动部（13a）、驱动轮构件（13b）、从动轮构件（13c）以及环状构件（13d）。引导部（15）以使设于连结部（19）的轴部（14）沿车宽方向移动的方式引导轴部（14）。借助在两个齿条（16a、16b）之间配置有小齿轮（16c）的倍速导轨（16），一个齿条（16b）与滑动基座（12）相连结，另一个齿条（16a）连结于车门（104）侧，小齿轮（16c）连结于连结部（19）侧。
摘要（英）：

Provided is a small plug door device capable of performing an opening/closing operation and a plugging operation with a door drive mechanism for causing a force in a vehicle front-rear direction to act on a door, and further applicable also to a one-panel sliding door. A slide base 12 is installed slidably in a vehicle width direction relative to a fixed base 11. A door drive mechanism 13 for moving one door 104 in a vehicle front-rear direction via a connecting portion 19 has a drive portion 13a including an electric motor 21, a drive wheel member 13b, a follower wheel member 13c, and an endless member 13d, and is installed on the slide base 12. A guide portion 15 guides a shaft portion 14 provided on the connecting portion 19 so as to move the shaft portion 14 in a vehicle width direction. In a double-speed rail 16 in which a pinion 16c is disposed between two racks (16a, 16b), one rack 16b is connected to the slide base 12, the other rack 16a is connected to the door 104 side, and the pinion 16c is connected to the connecting portion 19.
