Abstract

PURPOSE:To obtain a pressure balancing mechanism which can be manufactured easily and whose manufacturing cost is low by offsetting substantially the pressure of a pressure testing tank for working on a load rod which is connected to a test piece in the pressure testing tank. CONSTITUTION:As for a sliding rod 21, to one end thereof, one end of a test piece is connected, and to the other end, a driving part for giving a load to a test piece is connected. Between this sliding rod 21 and a cover part of a pressure testing tank 22, a fixed cylinder 23 and a pressure balance cylinder 24 are provided. Also, on the inlet of the pressure testing tank 22, a cap 25 is provided, and the sliding rod 21 passes through its center part. Moreover, the sliding rod 21 is provided with a pressure leading-in hole 35 for leading the pressure P in the pressure testing tank 22, to a space 34, and offsetting substantially the pressure in the pressure testing tank 22 for operating on the sliding rod 21.
