The present invention aims to apply a vertical load to a specimen with high precision even if the specimen shifts horizontally. A load application device includes: a hydraulic actuator which applies a load to a specimen; a support structural body which supports the hydraulic actuator along a vertical direction; a horizontal guide surface which guides the support structural body along a horizontal direction; and a bearing which is interposed between the support structural body and the horizontal guide surface and bears the support structural body so as to be horizontally shiftable relative to the horizontal guide surface. This bearing includes a plurality of spherical bodies supported so as to be independently rollable, and the plurality of spherical bodies are held in contact with the support structural body or the horizontal guide surface.
