Automation component , in particular gripper unit , linear unit or pivoting unit, having a drive , having an actuating member which is driven by the drive and is designed as a rotary member which can be rotationally driven by the drive, having a gear mechanism which comprises a spindle shaft as an input member, a spindle thread which is arranged on the spindle shaft, and a driver which meshes with the spindle thread as an output member, the rotary member being movement-coupled to the spindle shaft , the gear mechanism being designed so that there is self-locking such that an inhibiting resistance caused by static friction has to be exceeded in order to allow movement of the output member , an angular overrunning clutch being provided between the rotary member and the spindle shaft , so that, when the direction of rotation of the rotary element is reversed, the rotary member can be rotated over a clearance angle so as to be decoupled from the spindle shaft , the angular overrunning clutch having a first element , which is coupled to the rotary member for conjoint rotation, and a second element , which is coupled to the spindle shaft for conjoint rotation, the first element or the second element having two rotary portions , which extend in parallel with the axis of rotation , and a free space between two adjacent rotary portions , the second element or first element having driver portions which engage in the corresponding free spaces , the driver portions being freely rotatable over the clearance angle into the free spaces , characterized in that the rotary portions and the driver portions are designed as ring segments and the outer diameter (A) of the rotary portions corresponds to the outer diameter (B) of the driver portions . having a drive , having an actuating member which is driven by the drive and is designed as a rotary member which can be rotationally driven by the drive, having a gear mechanism which comprises a spindle shaft as an input member, a spindle thread which is arranged on the spindle shaft, and a driver which meshes with the spindle thread as an output member, the rotary member being movement-coupled to the spindle shaft , the gear mechanism being designed so that there is self-locking such that an inhibiting resistance caused by static friction has to be exceeded in order to allow movement of the output member , an angular overrunning clutch being provided between the rotary member and the spindle shaft , so that, when the direction of rotation of the rotary element is reversed, the rotary member can be rotated over a clearance angle so as to be decoupled from the spindle shaft , the angular overrunning clutch having a first element , which is coupled to the rotary member for conjoint rotation, and a second element , which is coupled to the spindle shaft for conjoint rotation, the first element or the second element having two rotary portions , which extend in parallel with the axis of rotation , and a free space between two adjacent rotary portions , the second element or first element having driver portions which engage in the corresponding free spaces , the driver portions being freely rotatable over the clearance angle into the free spaces , characterized in that the rotary portions and the driver portions are designed as ring segments and the outer diameter (A) of the rotary portions corresponds to the outer diameter (B) of the driver portions . <EOS>
