塞拉门装置
Abstract:
本发明提供一种能够抑制门的气密性的降低并有助于小型化的塞拉门装置。塞拉门装置(1)具备：作为驱动源的电动马达(60)；塞拉动作部(10)，其基于电动马达(60)的驱动力使设置于车辆的乘降口的门(300)沿车辆的宽度方向(ZA)移动；前后动作部(20)，其基于驱动源的驱动力使门沿车辆的前后方向移动；移动抑制部(70)，其能够抑制门(300)的前后方向(ZB)上的移动；以及行星齿轮机构(80)，其在门(300)的前后方向(ZB)上的移动被移动抑制部(70)抑制的情况下将电动马达(60)的驱动力向塞拉动作部(10)分配，在门(300)的前后方向(ZB)上的移动没有被移动抑制部(70)抑制的情况下将电动马达(60)的驱动力向前后动作部(20)分配。
Abstract(English):

One object is to provide a plug door device that can make a contribution to a size reduction thereof, while suppressing a decrease in airtightness of a door. A plug door device is provided with an electric motor, a plug operation portion that moves a door in a width direction of a vehicle, a front-back operation portion that moves the door in a front-back direction of the vehicle, a movement suppressing portion that can suppress movement of the door in the front-back direction, and a planetary gear mechanism that distributes a drive force of the electric motor to the plug operation portion when movement of the door in the front-back direction is suppressed by the movement suppressing portion, and distributes a drive force of the electric motor to the front-back operation portion when movement of the door in the front-back direction is not suppressed by the movement suppressing portion.
