Abstract: A control device is mounted on a vehicle including a door opening and closing mechanism for opening and closing a door of an entrance and exit where a passenger gets on and off, and a shift device for changing a driving range of a transmission. The driving range is input to the control device and the control device opens and closes the door by the door opening and closing mechanism. The control device permits opening of the door when the driving range is a parking range, and prohibits a change of the driving range of the shift device when the driving range is the parking range and the door is open.

Abstract: A passage bead seal of a fuel cell joint separator includes a straight portion and curved portions. An oxygen-containing gas bridge section connecting the inside and the outside of a portion surrounded by a passage bead seal includes inner tunnels and outer tunnels coupled to an inner side wall and an outer side wall of a straight portion, and protruding in a separator thickness direction. The tunnel height is determined to be smaller than the bead seal height by not less than a predetermined value in a manner that a line pressure applied by a compression load to a front end surface of the straight portion becomes the same as a line pressure applied by the compression load to a front end surface of the curved portion.
