Provided is a bushing device capable of improving a tight-fitting structure in which a bushing is tightly pushed into a water-communicating hole. A bushing collar is placed between the bushing and an inner wall of the water-communicating hole. An outer surface of the bushing is tapered, and an inner surface of the bushing collar is tapered in accordance with the outer surface of the bushing. When the bushing is secured to the water-communicating hole, the bushing collar is tightly fit into the water-communicating hole as a result of the wedge-shaped effect exerted between the tapered surfaces of the bushing and the bushing collar. Since the tapered surface of the bushing and the bushing collar are tightly fit, it is possible to significantly improve a heat-conductive efficiency between the bushing and the bushing collar, and reducing procedures needed to exchange casings with a good usability.
A bushing device in which a bushing is provided on a device body to be in communication with a water-communicating hole so that an aqueous medium is supplied to said bushing;
A water-communicating mechanism in which a bushing is provided on a device body to be in communication with a water-communicating hole, so that an aqueous medium is supplied to said bushing, an outer surface of which is tapered;
A method of making a water-communicating mechanism in which a bushing is provided on a device body to be in communication with a water-communicating hole so that an aqueous medium is supplied to said bushing,
