ABSTRACT:
A dowel-like device is described for locating a component (1) having a through-bore (33) relative to a reference part (2) provided with a bore (34), the through-bore and the bore having the same inside width. In order for the dowel to permit an accurate, repeatable positioning of the component on the reference part without loss of precision, it is provided with a cylindrical bushing (3), which is elastic in a radial direction at least over part of its length and is internally conical. A rotatable bolt (9) extending axially into the conical bushing section (4) is locked against movement in the axial direction and cooperates with a cone member (7) which extends into the conical bushing section, so that upon rotation of the bolt, the cone member moves axially, causing its exterior surface to push outwardly against the bushing. This expands the bushing into firm contact with the wall of the bores in the component and the reference part.
