A wobbler (1) having one first structural member (2) and one second structural member (3), which are movably arranged to each other to form a wobbler body. By means of a relative movement of the structural members the length of the wobbler body is adjustable between a first extreme position, where the wobbler body has a predetermined first length, and a second extreme position, where the wobbler body has a predetermined second length that is at least 5% longer than the first length. |
