WIPO Patent Application WO/1995/016144

A1

A bearing structure for radially rotatably supporting a rotating shaft disposed in a valve body serving as a shell unit wherein a truncated cone-shaped fitting hole (25) which has an axis in the same direction as that of the rotating shaft (21a) is provided in the valve body and wherein the rotating shaft is supported by means of a tubular member (23) which has therein an insertion hole (23a) into which the rotating shaft (21a, 31a) is fittingly inserted in such a manner as to freely rotate therein, has an external shape of a truncated cone, and is fittingly inserted into the fitting hole (25). With this bearing structure, it is possible to secure a desired bearing function irrespective of the deformation resulting from expansion and/or contraction of bearing constituent members due to change in ambient temperatures.
