PROBLEM TO BE SOLVED: To provide a safety device for an operating arm, which prevents application of an excessive force to the operator, and improves the safety of the operator. SOLUTION: According to the structure of the safety device, a grip member 7 which the operator grips and a base stand driven along a predetermined moving passage are connected together by first and second link portions 13, 14, and when an excessive force is applied to the grip member 7, the first link portion 13 continuing with an operating member 7 is separated from the second link portion 14 fixed to the base stand 4. Thus application of the excessive force to the operator from the base stand 4 via the second link portion 14, the first link portion 13, and the grip member 7, is prevented.
