Load sensor, pinch detection apparatus and load detection apparatus

摘要

A load sensor is formed of first and second opposing electrode members. The members make contact to mutually conduct electrically when a load is applied to the load sensor. The first electrode member consists of an elastic tube having at least a part of the circumferential segment formed into a conductive portion. The second electrode member consists of a flexible center electrode with conductivity on at least the outer circumferential portion positioned inside the elastic tube of the first electrode member so that the conducting surfaces face each other. An insulating linear member is wound around the center electrode at a predetermined winding distance.
