ABSTRACT:
A device for holding two structural parts (1, 2) in a spaced relationship with respect to each other, having a spacer for filling the distance between the two structural parts, the spacer having a support part (3) which can be brought into a position fixed for rotation with respect to the first structural part (1) and a rotary drive part (4) which can be displaced axially with respect to the support part (3) by rotation, the support part (3) and the rotary drive part (4) resting on a helical engagement surface (7, 8) which has a slope which is opposite the slope of a thread of a screw (5) which, upon being screwed into an axial opening (11) in the rotary drive part, carries the latter along in rotation. The support part (3) and rotary drive part (4) are magnetically attached to each other, the support part (3) and/or the rotary drive part (4) being of permanently magnetic material.
