PURPOSE: A compression testing device is provided to prevent a testing piece from being bent in one side in a compression test as both surfaces of the testing piece arranged between first and second jig are pressurized regularly by fluid pressure. CONSTITUTION: A compression testing device comprises a first jig(20), a second jig(30), a hydraulic device(40), and a sealing member(60). The first jig includes a testing piece mounting unit. The second jig includes a through-hole of a shape identical to that of the testing piece mounting unit in one surface. The second jig is joined separable so that the testing piece mounting unit and the through hole face each other. The sealing member maintains the airtightness of the first and second jigs by being sealed edge portions of the testing piece mounting unit and the through-hole when the first and second jigs are joined. |
