A regulating flap reduction gear for an electrically driven regulating flap for regulating a gas or liquid volume flow includes two parallel bearing plates between which gear parts are rotatably arranged. A plurality of spacers keep the two bearing plates at a distance from one another. The plurality of spacers are designed as tabs of one, first bearing plate, which are bent by 90? from the plane of the first bearing plate and have at least one lateral projection. The tabs are inserted with their free tab ends into plug-in openings of the other second bearing plate until their at least one lateral projection rests against the second bearing plate.
