PROBLEM TO BE SOLVED: To provide a mole repellent device that prevents repellent effect from being reduced by learning effect and provides efficient repellent effect, without being affected by conditions of ground or soil, and without selecting an installation position of the device in the mole repellent device.SOLUTION: A mole repellent device comprises a high pressure impulse voltage generator 2 including a capacitor 4, a changeover switch 5, a resistor 6, a DC power supply 7 and a step-up transformer 8, and a pair of electrode rods Pa, Pb connected to the step-up transformer through insulated wire 3. The electrical charge of the capacitor charged by the DC power supply through the resistor is discharged to a primary coil of the step-up transformer using the changeover switch, and the impulse voltage generated in a secondary coil is guided to the pair of electrode rods inserted in the cultivated land using the insulated wire.COPYRIGHT: (C)2014,JPO&INPIT【課題】モグラ忌避装置において、装置の設置位置を選ばす、接地あるは土壌の状態に左右されることなく、学習効果による忌避効力減退を阻止し、効率良い忌避効果を与えるモグラ忌避装置を提供すること。【解決手段】コンデンサ4、切り替えスイッチ5、抵抗器6、直流電源7、昇圧トランス8を備えた高圧衝撃電圧発生装置2と、絶縁電線3を介して、昇圧トランスに接続される1対の電極棒Pa、Pbからなるモグラ忌避装置において、抵抗を介して直流電源で充電したコンデンサの電荷を、切り替えスイッチで昇圧トランスの1次コイルに放電させて2次コイルに生じる衝撃電圧を、耕作地中に挿入した1対の電極棒に絶縁電線で導くことを特徴とする。【選択図】 図1
