PURPOSE:To guide walking animals one by one in separated state by using a passing detection means to detect an animal passing through a certain point downstream in walking direction with respect to a gate and applying a resistance to the opening of the gate. CONSTITUTION:When an objective animal is passed through a door 12 downstream in walking direction with respect to a gate G, the animal is detected by a passing detection means S and a resistance is applied to the opening of the gate G with a resist-imparting means 3 by a controlling means 11 to restrict the passing of the following animals through the gate. |
