PROBLEM TO BE SOLVED: To provide a new support device of a trolley line capable of holding horizontally the position of the trolley line on the main line side and the position of the trolley line on a crossover. SOLUTION: A suspension line M1 on the main line side and a suspension line M2 on the crossover side are connected by a support arm 2. The trolley line T1 on the main line side and the trolley line T2 on the crossover side are connected by a connecting arm 3. The connecting arm 3 is suspended to the central lower part of the support arm 2 by a pair of suspending rods 4. The pair of the suspending rods 4 are made into the same lengthes and both of upper ends thereof are pivoted on the central lower part of the support arm 2, and the lower ends thereof are pivoted on one side or the other side of the connecting arm 3 respectively. An isosceles triangle is formed by two suspending rods 4 and the connecting arm 3, and its vertex is suspended to the center of the support arm 2, and two trolley lines T1 and T2 are supported by both the ends of the bottom. Therefore, a difference of elevation occurs between two suspension lines M1 and M2 and even when the support arm 2 is thereby inclined with respect to a horizontal level, the two trolley lines T1 and T2 only perform vertical movement slightly while maintaining the horizontal position with each other.
