The resin contact member 51 having the above is fixed. Further, the support member 50 is formed with a sliding bowl-shaped recess 52 facing the open end 31a of the screw accommodating portion 31. The screw 30 is held in the screw accommodating portion 31 in a state where the tip of the contact member 51 provided at the shaft end portion 30b is in contact with the recess 52.

According to the above configuration, when the recess 52 of the support member 50 comes into contact with the shaft end portion 30b (contact member 51) of the screw 30 from the axial direction, the shaft end portion 30b forms a sliding bowl-shaped bottom portion of the recess 52. You will be guided to 52a. As a result, the flexible screw 30 can be rotatably and stably supported by using the bottom portion 52a of the recess 52 provided in the support member 50 as the support point P. As a result, it is possible to secure a high texture by suppressing the generation of vibration and operating noise accompanying the rotation of the screw 30.

The shape of the contact portion (tapered surface) of the contact member 51 and the shape of the sliding bowl of the recess 52 may be arbitrarily changed. Then, the shaft end portion 30b of the screw 30 may be in direct contact with the recess 52 of the support member 50.

In the second embodiment, each opening / closing drive device 65 of the sunroof device 66 has a configuration in which the movable panel 64 is tilted / closed and slid open / closed by moving the drive shoe 67 as a moving body back and forth. .. However, the present invention is not limited to this, and a configuration may be performed in which either a tilt opening / closing operation or a slide opening / closing operation is performed.

-In the third embodiment, the rail member 82 is made of metal and the guide member 83 is made of resin. However, the present invention is not limited to this, and at least the screw accommodating portion 31C may be formed of resin. Even if such a configuration is adopted, the sliding contact sound of the screw 30C rotating in the screw accommodating portion 31C can be suppressed to be small. In this case, the rail member 82 and the guide member 83 do not necessarily have to be connected to each other.

Further, regardless of the material thereof, a configuration may be adopted in which the guide rail 10C is formed by connecting the rail member 82 and the guide member 83. As a result, the guide rail 10C having the guide portion 20C, the screw accommodating portion 31C, and the slit portion 32C can be easily formed.

In the third embodiment, the fitting protrusion 92 as the first fitting portion provided on the rotary drive unit 40C has an annular shape. Then, the axial end portion 83x of the guide member 83 having a function as the second fitting portion to be fitted to the fitting protrusion 92 also has a substantially columnar outer shape. However, the present invention is not limited to this, and the second fitting portion provided at the axial end portion of the guide member 83 and the screw accommodating portion 31C formed inside the guide member 83 are coaxial and the rotation drive portion 40C side. If the first fitting portion and the output shaft 89 provided in the above are coaxial, the shapes of the first fitting portion and the second fitting portion may be arbitrarily changed.

In the first embodiment, the elevator 3 has a carrier bracket 11 for opening and closing the window glass 4 as a moving body, and in the second embodiment, the movable panel 64 of the sunroof device 66 is opened and closed. It is embodied in an opening / closing drive device 65 having a drive shoe 67 for the purpose as a moving body. However, the present invention is not limited to this, and the configuration of the moving body and its use may be arbitrarily changed as long as it moves by the rotation of the screw while being connected to the guide rail.
