1. A jig configured for a vibration test of a stator vane, configured for use in the vibration test for evaluating high cycle fatigue characteristics of the stator vane, the jig comprising:
a base plate that is configured to be fixed onto an excitation table of a shaker,
a first fixed wall that is fixed onto the base plate, wherein the first fixed wall is configured to fix a first end portion of the stator vane in a span direction of the stator vane,
a movable wall that is slidably placed on the base plate, wherein the movable wall is configured to fix a second end portion of the stator vane in the span direction of the stator vane,
a second fixed wall that includes an opening through which the stator vane extends and is fixed between the first fixed wall and the movable wall on the base plate, wherein the second fixed wall is configured to receive the stator vane through the opening, and
a force applying section that is disposed between the movable wall and the second fixed wall, and is configured to apply a load in the span direction to the stator vane.
