摘要： A lumen passability checking device includes: an expandable and shrinkable outer casing that contains a predetermined fluid, is expanded by a pressure of the contained fluid, and forms an external diameter substantially equal to that of a capsule medical device to be inserted into a body of a subject; and a shape manipulating unit that flows out the fluid contained in the outer casing to shrink-deform the outer casing. The outer casing is shrink-deformed by flowing out the fluid, while maintaining a state of being integrated with the shape manipulating unit.

摘要： A water pump includes a body, a fixing member to which the body is fixed hermetically via a gasket, and an impeller which is fixed to an end part of a shaft supported rotatably by the body and housed in a vortex chamber formed in the body or in the fixing member. Further, the impeller has a circular plate into which the end part of the shaft is inserted and a plurality of blades radially provided on the circular plate at one side facing the fixing member or the other side facing the body and project from the circular plate to the fixing member side or the body side. In the water pump, the gasket has an intermediate plate with high rigidity and metal gaskets disposed between the intermediate plate and the body, and between the intermediate plate and the fixing member for sealing. The intermediate plate extends in radial direction to keep a predetermined axial distance between an inner peripheral portion of the intermediate plate and an end part of the blades facing to the fixing member or to the body.
