PROBLEM TO BE SOLVED: To provide a supporting device, in which a supporting angle of a rigid train line is adjustable according to an angle of cant of a railroad and the rigid train line is not deviated from a center of the rail by adjustment. SOLUTION: The supporting device 1 comprises: a base 2; an insulator 3; a receiving member 4; a supporting member 5; and a press fitting 6. The base 2 is fixed on a ceiling S, and a pair of receiving members 4 are fixed to be apart in right and left sides via the insulator 3 below the base 2. The supporting member 5 is supported so that its angle is adjustable according to the angle of cant with respect to the receiving member 4. An upper part of the rigid train line 21 is supported by a saddle fitting 6 at a lower part of the supporting member 5. A mounting part 4c of the receiving member 4 has a cylindrical surface 4d substantially concentric with a lower trolley line 24 in a mounting state. A pair of right and left connecting parts 5c of the supporting member 5 have a cylindrical surface 5d overlapping the cylindrical surface 4d. The mounting part 4c and the connecting parts 5c are fixed through a bolt 7. A relative fixing angle of the supporting member 5 and the receiving member 4 can be changed by sliding the cylindrical surfaces 4d, 5d. COPYRIGHT: (C)2008,JPO&INPIT
