Abstract
A linearly operating motor for stepwise advance of a driven member (11), such as a shaft, comprises an elongated body (10) with length variable properties, and means (15) for changing the length of said body (10). The driven member (11) is provided with at least one locking member (12), whereby at length increase of said body (10) the locking member (12) is arranged, by means of said length increase, to be brought into engagement with said driven member (11) and said body (10) is adapted to act upon the locking member (12) in such a manner the locking member and the driven member (11) are displaced at length increase of the elongated body (10).
