Abstract: A detection mechanism includes: a detection unit that is provided on a contact body and detects contact with the contact body by a person; a conductive cloth provided in the detection unit, the conductive cloth being configured by weaving together two elements of a yarn to form an intersection point, the conductive cloth having conductivity; and a recess that is provided on an outer periphery of the conductive cloth and that severs the yarn.

Abstract: A steering wheel including: a detecting portion wound on a base portion that has a concave groove portion, the detecting portion being configured to detect contact of a person; an electrode that is sheet-shaped, the electrode structuring the detecting portion; and a convex portion formed at a side of the concave groove portion of the electrode, the convex portion projecting-out in a width direction of the electrode.

Abstract: There is disclosed a detecting device including a detecting portion that detects contact of a person with a contacted body, the detecting portion including: an insulating body, the insulating body being sheet-shaped; an electrode, the electrode being sheet-shaped, being disposed at at least one side surface side of the insulating body, and being less extensible than the insulating body; and a positioning hole, the positioning hole being formed so as to penetrate through the insulating body and the electrode, and the insulating body and the electrode being positioned by the positioning hole.

Abstract: A steering wheel in which detection is made of an electrostatic capacitance generated between a hand of an occupant and a sensor electrode of a rim section to detect contact of the occupant's hand with the rim. The sensor electrode is separated in a peripheral direction of the rim section into a first electrode and a second electrode. This enables the installation surface area of the sensor electrode to be made smaller, enabling the cost of the sensor electrode to be reduced.

Abstract: A sensor electrode and an insulating body are coupled together by a hot melt member in a sensor of a steering wheel. The sensor electrode makes contact with the insulating body at first protrusions so as to form through holes in the hot melt member. The hot melt member is accordingly able to stretch easily due to the through holes, enabling a high extensibility for the sensor to be achieved.
