Abstract:
1. An apparatus for driving to open and close a vehicular closing structure, comprising: between a vehicle body and a closing structure that is capable to swing up vertically with respect to the vehicle body: a control unit for monitoring a position of said closing structure and a direction of movement of said closing structure, and for controlling operation of the clutch unit and the opening and closing driving force generating unit, wherein: when driving force is being transmitted from said opening and closing driving force generating unit to said closing structure to move said closing structure in an opening direction, and said closing structure is determined by said control unit to have reached a predetermined position before a fully opened position, the control unit is operable to disconnect the opening and closing driving force generating unit from the closing structure so that the closing structure moves into the fully opened position, and is thereafter held in the fully opened position, by virtue of only a biasing force of the opening direction biasing unit; and; wherein said control unit is operable, after the disconnection of the opening and closing driving force generating unit from the closing structure, to detect closing of the closing structure from a weight thereof and to thereafter connect the opening and closing driving force generating unit to the closing structure so as to drive to open the closing structure a predetermined amount, and thereafter driving to close the closing structure.
