This invention concerns a device for power transmission suitable in particular for transmitting thrusting forces over linear and any variety of curved paths. This power transmission device has a guide channel (1) in which a series of transmission elements (10) are arranged. The transmission elements (10) can be brought into operative connection with a drive and their faces are in contact with one another. The face sides which contact have an annular ridge (11) and an annular groove (12) respectively. Groove (12) and ridge (11) fit together and rest one within the other when adjacent, elements are coaxially arranged. The cross sections of groove (12) and ridge (11) are such that, positioned one within the other, they can be pivoted one against the other. A linearly aligned series of transmission elements equipped in such a way and pressureloaded forms a kink-resistant rod, which exerts no essential radial forces in linear areas (1.2). In curved areas (1.1) of the path, the transmission elements (10) pivot against one another, to the effect that the pivoting occurs in a guided fashion and the power transmission even in the pivoted position occurs over more than a punctiform area.
