Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a device for adjusting the stroke of a tamping beam of a road finishing device that enables easy stroke adjustment without interrupting operation.SOLUTION: In a device for adjusting the stroke of a tamping beam of a road finishing device, the tamping beam is vertically vibrated while oscillated, between a top dead point and a bottom dead point by means of a cam shaft with an eccentric cam and a cam rotation axis. For this purpose, the cam is formed to change its eccentricity and offset adjustment is forcibly made on the cam rotation axis according to the change in the eccentricity.
