PROBLEM TO BE SOLVED: To provide a structure in which a multi-direction detection sensor to detect a two-dimensional direction is arranged with the two-dimension face as a front face and which can be used also as a fall sensor by detecting fall in front and rear directions (surface direction of two dimensions). SOLUTION: A support member 31 is fixed on the substrate 12. A hole is provided at the upper side of the support member 31, and a four-direction detection sensor 80 is inserted into the hole with a gap 31a. Further, the four-direction detection sensor 80 is connected to the substrate 12 by coated wires 30. Then, as shown in Fig.4(D), when an air cleaner 20 falls down to a floor, the upper part of the four-direction detection sensor 80 inclines in a gravity direction by its own weight of the four-direction detection sensor 80, and a ball 83 moves to the upper part of the four-direction detection sensor 80 and fall-down of the air cleaner 20 is detected.
