PROBLEM TO BE SOLVED: To detect horizontal force with high accuracy by providing force detecting means separately from a means for supporting a support means to a base body. SOLUTION: A support base 5 of similar figure to a support means 7 whereon a trainee holds to support a part of his weight is disposed under the support means 7 through elastic members 6a-6d formed of vetical load receiving members. The support base 5 is provided with displacement detectors 8a-8d. The support means 7 is provided with targets 9a-9d in correspondence with the displacement detectors 8a-8d to form a position reference at the time of the displacement detectors 8a-8d detecting the displacement quantity of the support means 7. The displacement detectors 8a, 8b detect longitudinal distance change between the targets 9a, 9b, and the displacement detectors 8c, 8d detect vertical distance change between the targets 9c, 9d. With this constitution, required action force can be detected with high accuracy and high resolution. |
