Wave motion gear apparatus used in wave generation, has distortion gauge with resistance wire section which is adhesively fixed to end face of diaphragm side

摘要

A distortion gauge (41) has a resistance wire section (41b) adhesively fixed to an end face (22a) of a diaphragm (22) side. A connecting terminal section is adhesively fixed to the end face (23a) of a hub (23) side. The distortion gauge is adhesively fixed to the section of the boundary portion of the end faces. A connecting terminal section (41a) connects the resistance wire to a lead wire.
