PROBLEM TO BE SOLVED: To provide a technique for accurately applying a prescribed load to a hard tissue. SOLUTION: An oscillation arm 30 moves in a seesaw fashion about an oscillation shaft 32 which is supported by a support rod 20 and which serves as a fulcrum. A rotation arm 40 and a pressurizer 50 are provided on one end of the oscillation arm 30. One end of the rotation arm 40 is rotatably attached to the oscillation arm 30, and a load weight 80 is placed on the other end of the rotation arm 40. By rotating the rotation arm 40, the magnitude of a force to be applied by the load weight 80 to the pressurizer 50 is adjusted. More specifically, by displacing the load weight 80 to a predetermined position by rotation and then causing the load weight 80 to stop at this position, a static load corresponding to the rotation angle can be applied to the pressurizer 50. Further, by causing the load weight 80 to perform rotational motion, the magnitude of the force to be applied to the pressurizer 50 is periodically varied, so that a load which varies periodically can be applied to a hard tissue.
