<p>PROBLEM TO BE SOLVED: To put loads in and out rapidly in a narrow place and reduce labor and a burden at the time of opening/closing a door. SOLUTION: One end of a connecting wire is connected to a rear door springingly energized in an opening direction. A pulley body 6 for winding the connecting wire 1 is provided and energized in a winding direction by an additionally provided flat spiral spring 63. A one-way clutch 4 has a rotatable outer ring 44, and an input shaft 43 is positioned at its center. The input shaft 43 is integrally connected to the pulley body 6 and connected in the state of being relatively rotatable to the outer ring 44 only in the winding direction of the pulley body 6 by a roller body 42 interposed between the input shaft 43 and the outer ring 44. In case of opening and holding the rear door with the requested opening, a stopper body is advanced by an electromagnetic solenoid and fitted into an engaging groove 443 provided at the periphery of the outer ring 44 so as to regulate rotation of the outer ring 44.</p> |
