A safety joint (16) for connecting together a rotatable free and portion of a wrist device of an industrial robot and an operating device, such as a robot hand, a welder, or a painting machine, has a first joint base portion (18) which is secured to a free end (15) of a wrist device, and a second joint base portion (20) which is secured to an operating device (17). The first and second joint base portions (18), (20) are connected together rotatably by a shaft portion (22). The first joint base portion (18) is provided with an end plate (25) to prevent the second joint proximal portion (20) coming off. At least one shear pin (29) is employed to prevent the rotation of the second joint base portion (20) with respect to the first joint base portion (18). Breaking the shear pin (29) enables the second joint base portion (20) to rotate with respect to the first joint base portion (18). |
