PURPOSE:To realize a compact size of electromotive rotation up-and-down door and to secure the operation by composing the system to add later and fix a driving source, a gear box, an extension, and the like to a shaft elevating rotation up-and-down door of the type whose strut is divided into the upper member and the lower member. CONSTITUTION:While a shaft fulcrum 41 is provided to the upper member 31a of a strut 31 which consists of the upper member 31 and the lower member 31b, the upper member 31a is geared slidable in the longitudinal direction to the lower member 31b, and the upper member 31a is enforced to the upper side by an enforcing member 61 provided in the lower member 31b. At the side surface of the upper member 31a, an extension T in which a rotation output is converted to a linear reciprocating output is hung down, its lower end is attached to a thin gear box G fixed to the lower member 31b, and a motor M and a controller C are arranged integrally to the box G in the direction crossing to the main surface of the box G. Furthermore, the other side strut is also composed in the same manner. In this case, the system may be composed by providing a connecting rod, a pendulm lever, and the like, provided in parallel to the holding arm. |
