An apparatus for limiting the operation range of an industrial robot, wherein a display portion (7) to display, e.g., the angle of rotation is provided on a fixed side (1) of a turning portion of a shaft that turns, and a range limiting member (6) having a dog and a stopper is movably arranged on said display portion (7). When the industrial robot is going to rotate in excess of a specified range of rotation during an operation, a limit member (81) provided on the moving side (2) of the shaft portion comes into contact with a dog (61) on the fixed side (1), whereby an overtravel is detected and an alarm is produced to indicate that the specified range of rotation has been exceeded. When the robot is further going to pivot due to inertia or the like, a buffer member (82) abuts against a stopper mechanism (62) to prevent the robot from turning excessively. |
