PURPOSE:To obtain an oscillation sending device which senses both vertical motion and horizontal motion excellently by providing an annular contact weight to the lower end of a suspension rod which is freely oscillatory at the upper end of the vertical part of a rotatable bell crank and a contact piece therein. CONSTITUTION:When a case enters lateral oscillation by receiving horizontal motion, the contact piece 8 moves laterally together with the case 1 toward a lateral motion weight 16 which is to hold its stationary position by inertia and the contacts it, and an electric signal is outputted through a relay 25. At this time, a seat piece 13 slants slightly on a support part 12 to allow contacting, but when the oscillation is less than specified, the contacting is not caused. Further, vertical motion is applied to the case, the base part 1 of the case moves up or down to an elevation weight 17 which is to become stationary by inertia, so the bell crank 10 rotates clockwise or counterclockwise slightly to bring the contact piece and lateral motion weight 16 into contact with each other, sending out the electric signal. When the cover 19 of the weight 17 is in contact with a base plate 2, the sensing device does not operate. |
