PROBLEM TO BE SOLVED: To provide a support device of a rigid body electric traction capable of maintaining an adjusted cant angle by easily adjusting a support angle of the rigid body electric traction according to the cant angle of a roadway, in a narrow tunnel.SOLUTION: A rigid body electric traction support device 1 includes an angle adjusting mechanism 4 for supporting a rigid body electric traction 21 so as to be capable of inclining to an insulator 3 according to a cant angle. The angle adjusting mechanism 4 is provided with a receiving member 5 joined to the insulator 3, and a support member 6 supported by the receiving member 5 so that a relative angle can be vertically changed in the lateral direction and supporting the rigid body electric traction 21. A lower part of the receiving member 5 is provided with a lower engaging part 10 having a plurality of axial directional projection strips 13 of projecting in the radial direction in the circumferential direction on a circular arc-shaped upper side surface 12 having the axis in the extension direction. The support member 6 is provided with an upper engaging part 14 having a circular arc-shaped lower side surface 16 along the circular arc-shaped upper side surface 12 of the lower engaging part 10 of the receiving member 5, and including a plurality of axial directional engaging grooves 17 for engaging with the projection strips 13 in the circumferential direction. |
