PROBLEM TO BE SOLVED: To provide a strain gauge holder with a light-weight and simple structure.SOLUTION: A strain gauge holder 1 is constituted of a holder body 11 having two plate-like sidewall parts 11a to be attached to a side surface of a pipe 3, a gauge pressing member 21 for pressing a strain gauge 2 to the side surface of the pipe 3 and a feeding mechanism for applying pressing force to the gauge pressing member 21, and configured to move the gauge pressing member 21 by the feeding mechanism in a guide groove 12 formed by the sidewall parts 11a and press the strain gauge 2 to the side surface of the pipe 3. The feeding mechanism includes a bush 32 having a cylindrical part 32a whose inner surface is thread-cut and a flange-like part 32b formed on a tip of the cylindrical part 32a and a feed screw 31 to be screwed into the rear of the gauge pressing member 21 and is configured to screw the screwed feed screw 31 into the bush 32 attached to the holder body 11 and move the gauge pressing member 21. |
