  • an open-close structure supported movably on a guide mechanism, an electric clutch for intermittently connecting the guide mechanism to an open-close structure holding mechanism, a clutch drive adjusting a transfer keeping force of the electric clutch, and a control means for controlling the clutch drive so that the clutch drive sets the transfer keeping force of the electric clutch at a level smaller than that in moving the open-close structure, in order to suitably stop and hold the open-close structure at a predetermined open degree, wherein the level is that in which a manual operation can make the open-close structure move.
