<p>PROBLEM TO BE SOLVED: To provide a weighing unit having a water proof structure which can solve at once a problem having a danger of breakage when cleaning by a brush or the like and high temperature/high pressure cleaning are performed for a thin rubber diaphragm.SOLUTION: A weighing unit is built in a weighing device of a waterproof specification, and the weighing unit includes: a through hole provided on an external wall of the weighing unit; a connection part for transmitting a load acting on an external load receiving part to a load cell that is inserted into the through hole and put inside the weighing unit; and a sealing part for sealing a gap between the connection part and the through hole. This sealing part has a hollow rigid sleeve into which the connection part is inserted; a first thin metal film for sealing a gap between one opening part peripheral edge of the rigid sleeve and the through hole peripheral edge; and a second thin metal film for sealing the gap between the other opening part peripheral edge of the rigid sleeve and a connection part peripheral edge.</p> |
