PROBLEM TO BE SOLVED: To establish a method of a creep test of precast concrete products, such as a PC pole, and to provide a support fixture capable of obtaining accurate creep contraction data in the creep test. SOLUTION: The support fixture laterally supports a plurality of columnar specimens 20-23 in an arranging state in a line, and matches the axial lines of the plurality of columnar specimens 20-23. The support fixture has a support section 2 having, on the upper surface side, a support groove 4 for laterally positioning the plurality of columnar specimens 20-23 in the arranging state in a line. The support groove 4 of the supporting section 2 is formed in tapered surfaces 5 and 5 of a predetermined angle with which two facing surfaces bring part of the outer peripheral surfaces of the specimens 20-23 into contact, the part of the outer peripheral surfaces of the plurality of specimens 20-23 is brought into contact with the tapered surfaces 5 and 5, thereby supporting the plurality of specimens 20-23 in the support groove 4 in a matched state of the axial lines. When a load is applied on the plurality of specimens 20-23 by a loading means, since the creep load in the axial line direction can be applied surely to the axial lines of the plurality of specimens 20-23, thus, high-accuracy data can be obtained.
