Patent ID: 8333719

Claim:
A load apparatus which applies a load to hard tissue, comprising: a support member; an oscillation arm which moves in a seesaw fashion about an axis serving as a fulcrum, the axis being supported by the support member; a pressure mechanism which is provided on one side of the oscillation arm with respect to the fulcrum; and a balancer which is provided on the other side of the oscillation arm with respect to the fulcrum, wherein the pressure mechanism includes: a load weight disposed on the one side of the oscillation arm with respect to the fulcrum; a pressurizer for applying to the hard tissue a load corresponding to a force supplied by the load weight; and an adjustment unit disposed on the one side of the oscillation arm with respect to the fulcrum, wherein the adjustment unit rotates the load weight to adjust a magnitude of the force to be applied to the pressurizer by the load weight.
