<P>PROBLEM TO BE SOLVED: To provide a wing door opening/closing device in which a driving force transmission mechanism for transmitting driving force to a crank arm is simplified and downsized. <P>SOLUTION: The wing door opening/closing device 1 is formed of a main body casing 2, the crank arm 3, a drive motor 4 for generating driving force for rotating the crank arm 3, and the driving force transmission mechanism 5 for transmitting the driving force of the drive motor 4 to the crank arm 3. The driving force transmission mechanism 5 has: a ball screw 34 having a screw shaft 40, and a nut 41 connected to the crank arm 3 on one side of a connection shaft 13 close to a wing door 105; and a bearing 42 for bearing both of loads in a thrusting direction and a radial direction operated on the screw shaft 40. <P>COPYRIGHT: (C)2007,JPO&INPIT |
