Claims

[Claims for Utility Model Registration] (1) A step motor is connected via a link mechanism to a rotary lever whose operation is regulated at its maximum rotation position, and the step motor is connected to a rotary lever whose operation is restricted to its maximum rotation position. A control link device characterized in that an over-rotation range is set in which the rotation is continued even after being regulated to a certain position, and the link mechanism is provided with a spring member that absorbs the over-rotation range. (2) The link mechanism is provided between a drive lever fixed to the drive shaft of the step motor, a driven lever rotatably supported by the drive shaft, and the driven lever and the drive lever. It is comprised of a spring member that transmits the driving force of the drive lever to the driven lever and absorbs the overspeed range of the step motor, and a link rod that connects the swinging end of the driven lever and the swinging end of the rotating lever. The control link device according to claim 1 of the above-mentioned utility model registration claim. (3) the spring member is provided so as to span between one end of the drive lever and one end of the driven lever;
The control according to claim 2 of the utility model registration claim, which comprises a coil spring that absorbs the over-rotation range of the step motor by expansion or contraction in the axial direction when the rotation lever is regulated to the maximum rotation position. link device. (4) The spring member is disposed coaxially with the drive shaft of the step motor by being sandwiched between and engaged with the drive lever and the driven lever, and the rotation lever is restricted to the maximum rotational position. 3. The control linkage device according to claim 2, wherein the control linkage device comprises a coil spring which absorbs the over-rotation range of the step motor by twisting around the axis when the step motor is rotated.
