Abstract

At a sensor electrode of a steering wheel, a protruding portion protrudes from a main body portion. A first thread and a second thread each extend in the protruding portion and effect conduction between a terminal at the protruding portion and a main body portion. Therefore, even if there is no conduction between the first thread and the second thread at intersection portions between the first thread and second thread in the protruding portion, the first thread and the second thread may each effect conduction between the terminal and the main body portion, and a degradation of conduction performance of the sensor electrode may be suppressed.

Claims7

Dependent claims

A sensing mechanism, comprising:

a sensing portion provided at a contact body, the sensing portion configured to sense touching of the contact body by a person;
a conductive fabric provided at the sensing portion, the conductive fabric comprising a first thread having conductivity and a second thread having conductivity, which are woven;
a main body portion provided at the conductive fabric;
a protruding portion provided at the conductive fabric, the protruding portion protruding from the main body portion in a direction that is different from an extension direction of the first thread and an extension direction of the second thread;
and
a terminal provided at the protruding portion, at least one of the first thread or the second thread extending in the protruding portion and effecting conduction between the terminal and the main body portion.
