<P>PROBLEM TO BE SOLVED: To provide a window opening/closing unit and a window opening/ closing device provided with the window opening/closing unit that can efficiently transmit driving force to a window opening/closing body in putting the window opening/closing body in opening/closing operation. <P>SOLUTION: This window opening/closing unit W is provided with a link mechanism RK comprising a first arm 20, a second arm 21 and a third arm 22. The base end side of the third arm 22 is connected to the window opening/ closing body 14, while the tip side is provided with a cutout part 36 engaged with a lock pin 19a of an internal thread body to be a drive source. When the opening of the window opening/closing body 14 is within the prescribed opening including a totally closed state, the internal thread body and the third arm 22 are directly operation-connected to each other by engaging the cutout part 36 with the lock pin 19a. Consequently, the driving force of the internal thread body is directly power-transmitted to the window opening/closing body 14 through the third arm 22 to improve transmission efficiency. <P>COPYRIGHT: (C)2003,JPO |
