Claims

[Claims for Utility Model Registration] Two engaging protrusions 5a and 5b are provided on the operating shaft 14, which rotates based on the rotation of the slat angle adjusting shaft 4, which is rotationally driven by the motor 12. The engaging protrusions 5a, 5 due to reverse rotation
b in contact with the engaging pieces 9a, 9b constituting the limit switch 11, and
In the slat angle adjustment device for stopping 2, the operating shaft 14 is composed of an outer cylinder shaft 15 and an inner shaft 16 rotatably fitted into the outer cylinder shaft 15, and the inner shaft 16 is a slat angle adjustment shaft. 4, and the outer cylinder shaft 15 is provided with two engaging protrusions 5a and 5b that engage with the engaging pieces 9a and 9b, and the outer cylinder shaft 15 and the inner shaft 16 are provided with two engaging protrusions 5a and 5b that engage with each other. Engagement means 17 and 18 are provided for rotating both together, and the engagement means 17 and 18 rotate the inner shaft 16 from the state of rotation of both together.
A slat angle adjusting device for an electric blind, characterized in that when the inner shaft 16 is rotated in the opposite direction, the inner shaft 16 is rotated by a predetermined angle and then engaged with the outer cylinder shaft 15 to rotate both together.
