PROBLEM TO BE SOLVED: To provide a displacement gage capable of performing an accurate material test even when a test piece is mounted on a displacement gage in a deviated manner.SOLUTION: A pair of contact pieces 53 and 54 in a grasping unit 24 of a lower arm 22 are supported by a linear motion guide formed of a rail 64 and a pair of blocks 65 and 66. The rail 64 constituting the linear motion guide is fixed to the lower arm 22. The contact piece 53 is supported by the block 65 movable along the rail 64, and the contact piece 54 is supported by the block 66 movable along the rail 64. An upper arm 21 also has a configuration similar to the lower arm 22. |
