The mechanism according to the present invention includes a driveshaft (11), provided with at least one bore (20) which is offset by an amount x with respect to the axis of rotation of the driveshaft and which extends parallel in all planes, to the axis of the said driveshaft, a satellite gear (13), provided with a pinion of pitch-circle diameter (D/2) housed inside the bore of the driveshaft, synchronising means (33) housed, free to rotate, inside a casing and in which there rolls, without sliding, the satellite pinion in a synchronous fashion and in the opposite direction from the driveshaft, and a crank wrist (pin) (14) which is offset by the amount x with respect to the axis of rotation of the satellite gear which carries it, and which moves with a stroke C. Such a mechanism is characterised in that it is fitted with means for angular offset (41) designed to allow adjustment of the stroke of the crank pin. This mechanism associated with a combustion engine, for example, particularly makes it possible to adjust the stroke of the pistons during operation. <IMAGE>
