Training device body, training device, and training system

摘要

A training instrument 10 comprises a hollow main body 12 formed of an aluminum alloy. The main body is constituted by two gripping portions 12a opposite to each other with a space therebetween and a coupling portion 12b coupling the two gripping portions. A load sensor 16 is arranged in the coupling portion inside the main body. The load sensor is a load cell, a strain gauge affixed to an interior of the main body, and a part of the main body to which the strain gauge is affixed functions as a strain body. Therefore, if a user applies a force so as to bring the two gripping portions close to each other or a force so as to move the two gripping portions away from each other, a load thereof is detected by the load sensor.
