Abstract / Hauptanspruch
A load change detection apparatus is provided with a base member, an elastic member, a first plate, a fixing member and heat flow sensors. The elastic member deforms according to a changed load applied to the elastic member, received by the receiving member. The first plate supports a surface of the elastic member on a side of the base member. The fixing member fixes the lower plate and the elastic member to the base member. The heat flow sensors, provided between the base member and the lower plate, output signals according to heat flowing between the lower plate and the base member. The heat flows due to heat generated or heat absorbed when the elastic member changes the elasticity shape thereof. Stress occurring when the elastic member deforms, is shut off by the first plate, thus direct transmission of the stress to the heat flow sensors is avoided.
