PCT No. PCT/SE92/00087 Sec. 371 Date Aug. 6, 1993 Sec. 102(e) Date Aug. 6, 1993 PCT Filed Feb. 13, 1992 PCT Pub. No. WO92/14933 PCT Pub. Date Sep. 3, 1992.Power transmission device for linear movement, comprising a principal member (2), which is movable along a displacement path, and a housing (1) which presents bearing means (10) for the movement of the member along the displacement path. A guide member (3) is arranged to guide the principal member in its displacement path, and a power member (4) is arranged to be able to be activated to apply a force to the principal member so that it moves while being guided by the guide member. A portion of the principal member is arranged to drive a connected device. The principal member (2) and the housing (1) and suitably also the power member (4) are each formed from longitudinally extending sections or profiles with essentially constant cross-sections along their lengths. In this manner the power transmission device can be produced in various lengths from a basic embodiment by cutting said profiles from raw material profiles having the cross-section referred to.
