摘要： An operating device operates a capsule endoscope with 6 degrees-of-freedom motion by using a magnetic field generator with respect to the capsule endoscope inserted into the subject. The operating device includes an operating unit including a fixed unit and a movable unit, and a force sensor incorporated in the operating unit. The operating unit has a three-dimensional shape substantially identical to the capsule endoscope and is a holdable size. The force sensor detects force information of the movable unit when the movable unit of the operating unit is operated once or continuously. The force information detected by the force sensor is output as instruction information for instructing 6 degrees-of-freedom motion of the capsule endoscope.

摘要： A water pump includes a mechanical seal provided between a housing and a rotary shaft for preventing cooling water from leaking from a whirl chamber. The housing forms a space into which cooling water leaked from between the mechanical seal and the rotary shaft is flown and a water vent for discharging cooling water flown into the space. The housing is joined with a thermostat cover to form a reservoir communicating with the water vent. The reservoir has a drain for releasing evaporated cooling water to the air and a control wall for preventing cooling water remaining as liquid from flowing out through the drain.
