摘要： The invention relates to an unbalance exciter (6) for a ground compaction device. Said unbalance exciter comprises a supporting structure (5) and an unbalanced weight (8, 9) which is mounted on the supporting structure (5) by means of a mounting (11a, 11b) so as to be rotatable about an axis of rotation (Y), which is fixed in relation to the supporting structure (5) during normal operation, in order to generate an intermittent excitation force to vibrate the supporting structure (5) during normal operation. In this case, the mounting (11a, 11b) of the unbalanced weight (8, 9) is at least partially arranged within the space which is circled by the unbalanced weight (8, 9) during rotation of the latter about the axis of rotation (Y). Owing to the fact that said space is used for receiving at least part of the mounting of the unbalanced weight (8, 9), it is possible to provide unbalance exciters (6) having very small axial overall lengths.
