<p>PROBLEM TO BE SOLVED: To provide a grip which can obtain a stable test result.SOLUTION: A main body 2 includes a cylindrical side wall 2a, and a pressing member 4, which presses grip members 3 in a direction mutually approaching and is prepared in the side wall 2a. Thereby, since a gap of the side wall 2a does not spread even if the pressing member 4 presses the grip members 3 strongly, sufficient fastening force is achievable, and a stable test result can be obtained as a result.</p> |
