Claims

[Scope of utility model registration request]

a door that opens and closes the doorway by being supported by a support arm rotatably attached to one side edge of the doorway of the vehicle in a front-back direction and moves in the front-rear direction;
a drive mechanism that is intermittably connected to the support arm to rotate the support arm in the front-rear direction; and a connection switching mechanism that connects and disconnects the drive mechanism to the support arm; A door check device for an automatic opening/closing type door that is automatically opened and closed when the support arm and the drive mechanism are connected, and manually opened and closed when the support arm and the drive mechanism are disconnected, wherein the support arm a connecting arm rotatably connected to a bracket that rotatably supports one end and is fixed to the door; and a connecting arm that is rotatably connected via the connecting arm and protrudes toward both the front and back sides at a longitudinally intermediate portion. a pair of sliding members fixed to the door and housed in a casing through which the check lever is inserted, and resiliently abutting both the front and back surfaces of the check lever by the action of a spring member; 1. A door check device for an automatic opening/closing type door, characterized in that the casing is provided with a resilient force adjusting means for adjusting the resilient force of the spring member by an external operation.
