Abstract:
1. A load transmission device, comprising: a first load-receiving member; a second load-receiving member that is assembled to said first load-receiving member so as to be relatively movable to form a pressure chamber as a compartment together with said first load-receiving member; a pressure-transmitting medium that is injected into said pressure chamber and comprised of spherical members the surface of which is lubricated; load-applying means which is installed in at least one of the first and second load receiving members, and applies a load onto said pressure-transmitting medium; wherein a load applied onto said pressure-transmitting medium is transmitted to said first and second load-receiving members through said pressure-transmitting medium; a screw hole is provided in said first load-receiving member through which hole a bolt for fastening a member to be fastened is thread-engaged; said second load-receiving member is placed to said member to be fastened; and a load in the tensile direction is preliminarily applied to said bolt by said pressure-transmitting medium through said first load-receiving member.
