Abstract: A mechanical measuring device includes a body case, a probe 10 extending from the body case and abutting against a predetermined portion of a biological soft tissue, a load measuring means 12 which is integrally connected to the probe 10 and which measures a load applied to the biological soft tissue by the probe 10, a moving means 14 for moving the probe 10 at a constant speed, and a distance measuring means 20 for measuring a moving distance by the moving means 14, and in a measuring operation of the biological soft tissue such as muscle and cartilage, the load applied to the biological soft tissue and the moving distance of the probe 10 are simultaneously measured in a state where the probe 10 is moved at a constant speed, thereby realizing inspection and diagnose of a mechanical state of the biological soft tissue.
