Apparatus suitable for containing a rotatable body such as a flywheel comprising at least two parts which together define a housing within which the rotatable body can be rotated. The parts of the housing are not rigidly fixed together but instead they are secured together by a length of high tensile strength tape which is wrapped around the parts to provide at least one layer of tape, overlapping at its edges which envelopes and is in contact with at least 50%, and preferably at least 70%, of the surface area of the housing. An impact of the rotatable body, or a part thereof, with the inner surface of the housing causes movement and/or deformation of at least one of the parts of the housing. This movement and/or deformation is resisted by the tape and the point loading resulting from the impact is thereby transformed into a loading over the surface of the parts wrapped with tape.
