Abstract: A transmission mechanism includes: an engagement portion provided to a drive link; a support shaft; a drive member supported rotatably around the support shaft, and having an engagement coupling portion with respect to the engagement portion and a transmission gear portion centered on the support shaft; and a torque input gear configured to be input with a driving torque in a state of being meshed with the transmission gear portion. The transmission mechanism is configured such that a position at which the engagement coupling portion is engaged with the engagement portion is disposed at a position same as a position at which the torque input gear is meshed with the transmission gear portion, in an axial direction of a coupling shaft of the drive link.

Abstract: PROBLEM: To stably support a door. SOLUTION: A door device includes: an engagement member provided in a variable link equipped with a variable connection length mechanism; and a cam member provided on a door and having a cam groove with which the engagement member engages. Furthermore, an extension end of the cam groove that comes into close proximity to an engagement part of the engagement member that moves within the cam groove, based on full opening movement of the door is an opening side end of the cam groove. The cam groove has a groove width change section being set on an opening side of the extension region including the opening side end, and a groove width of the cam groove in this groove width change section is narrower than a groove width on a closing side of the extension region beyond the groove width change section.
