PROBLEM TO BE SOLVED: To provide a sample fixing jig used for an accurate machined part durability evaluation method on a spring member, when load acts in the machined part spreading direction. ;SOLUTION: The sample fixing jig 20 is provided with a jig block body 21, in which slant faces 21b for abutting respective extension parts 25b on both sides of a bent matching spring part 25a of a specimen piece 25 are provided on both sides of a trough line part 21a while three or more specimens piece 25 can be arranged in parallel along the through line part 21a, a pair of fixing plates 22 removably mounted and fixed to the respective slant faces 21b to fix and hold the respective extension piece parts 25b clamped between the respective slant faces 21b and them, and spacer bodies 35, each of which is arranged between the slant face 21b and the fixing plate 22 in the vicinity of each fixed end part of the respective fixing plate 22 and is provided with a thickness equal to that of the specimen 25. The interior angle of the trough line part 21, constructed of the both slant faces 21b, is set to be a specimen fixing angle matching displacement of the bending angle of the specimen 25.;COPYRIGHT: (C)2001,JPO
