[0002]

2. Description of the Related Art A mounting bracket for a conventional electric roll blind shown in FIG.
, Mounting screws 62, plate-like rubber 6 as a vibration absorbing material
And 3. The electric roll blind 64 includes a winding shaft 65 and an electric motor 6 disposed in the winding shaft 65.
6 and a screen 67 and the like. The winding shaft 6
The screen 67 is suspended from and supported by the screen 5 so as to be able to be wound up and rewinded.

[0003] Both ends of the winding shaft 65 are rotatably supported by a shaft support 61a which is a vertical piece of the bracket body 61. A mounting portion 61b, which is a horizontal piece of the bracket body 61, is mounted on a mounting surface 68 via a rubber 63 by a mounting screw 62. The mounting surface 68 is, for example, the upper surface of a storage box configured to store the winding shaft 65 of the electric roll blind.

The interval is set so as not to contact with 61b.

In the electric roll blind 64 configured as described above, the screen 67 hanging down from the winding shaft 65 is moved up and down based on the operation of the electric motor 66, so that the amount of light collected from outside the window to the room can be measured. Adjustments are made. When the electric motor 66 is operated, the vibration of the motor 66 is transmitted to the bracket main body 61. If the thickness of the rubber 63 between the mounting surface 68 and the mounting portion 61b is sufficiently ensured, the vibration of the bracket main body 61 is reduced. Absorbed by rubber 63, mounting surface 6

[0006]

However, if the thickness of the rubber 63 is increased in order to reliably prevent the resonance of the mounting surface 68, the distance t1 between the mounting surface 68 and the winding shaft 65 increases. Then, there is a problem that the storage box or the like becomes large.

When the thickness of the rubber 63 is reduced in order to reduce the interval t1, the vibration of the electric motor 66 cannot be sufficiently absorbed, and the mounting surface 68 resonates to generate noise and the like. There is a problem.

It is an object of the present invention to provide a mounting bracket for an electric roll blind that can reliably prevent resonance of a mounting surface due to vibration of an electric motor and prevent a storage box from being enlarged.
