This invention relates to a driving device ( 1 ) comprising a drive shaft ( 3 ) that is rotatably supported in a housing, which driving device includes a position indicator for said drive shaft, wherein a cam ( 27 ) is present on the drive shaft, whose cam surface mates with one end of a feeler pin ( 29 ) which extends perpendicularly to the drive shaft, and which end is pressed against said cam surface under spring pressure ( 37 ), all this in such manner that movement of the feeler pin in its longitudinal direction, which is effected by the cam surface upon rotation of the drive shaft, provides an indication as regards the angular displacement of the drive shaft. |
