Abstract
A length adjusting mechanism for a driveshaft has two tubular profiles, an outer profile (6) and an inner profile (7). The outer profile (6) includes two circumferentially offset drawn in wedges (8) which project inwardly beyond the inner face of the otherwise circular cross-section of the outer profile (6). The wedges (8) engage grooves (11) of an inner profile (7). The grooves (11) are also drawn in. In this way it is possible to produce a pair of profiles which are suitable to transmit high torques and which, furthermore, do not include any parts which project in a radially outward direction.
