PROBLEM TO BE SOLVED: To reduce the total length of the test piece and the length of a test section as a length between fixtures. SOLUTION: A fatigue-testing fixture for the test piece 12, having shoulders 12a formed at fixed sections provided on both sides of the test section 12b in the axial direction, is provided with a tension load member 11 having protrusions 11a facingly disposed, having faces 11aa matched with faces 12aa continuously connected to the test section 12b at the shoulders 12a and formed with a first space 11b for penetrating the test section 12b between the protrusions 11a; a compression load member 13, having tip faces 13ba matched with tip faces 12ab facing the faces 12aa of the shoulders 12a so as to pinching the shoulders 12a by the protrusions 11a; and a restriction member 14 for restricting the shoulders 12a of the test piece 12 pinched by the tension load member 11 and the compression load member 13 in a direction perpendicular to a face on which the members 11, 13 are arrayed. The length of the test section is significantly reduced, and the test section is prevented from being buckled during compression load. COPYRIGHT: (C)2006,JPO&NCIPI
