To provide on-off durability testing equipment for an on-off body capable of performing the on-off driving of the on-off body not only at an angle of rotation of 180° or less but also at an angle of rotation of 180° or more.

In the on-off durability testing equipment for the on-off body, a drive motor 13 is arranged so that the drive shaft 13a thereof becomes coaxial with respect to the rotary shaft C of a door part 11 being the on-off body and rotated forwardly and reversely to open and close the door part 11 by the arm member 15 attached to the drive shaft 13a of the drive motor 13. The conversion of the rotary direction of the drive motor 13 is performed on the basis of the outputs of first and second limit switches provided corresponding to the angle-of-rotation range of the door part 11.
