Abstract: According to one embodiment, a seating detection sensor includes a strain generating body and a strain gauge. The strain generating body is held on a casing or a toilet seat. The strain generating body receives a load from the toilet seat via a shaft portion to generate a strain. The strain gauge is provided on the strain generating body and detects a strain amount of the strain generating body. A force release portion releases a force applied to an opening in a horizontal direction from the shaft portion in a state of the shaft portion abutting the opening so that the force is not converted downwardly in a vertical direction.
