Abstract: PROBLEM TO BE SOLVED: To provide a rotating device for a tightening machine for a rivet in which a C bracket and a pick-up device can be rotated each other and can easily be stopped at different angle setting positions. SOLUTION: In the rotating device for a tightening machine for a rivet, specially an automatic boring rivet or a pop rivet which is equipped with a rotatable pick-up device 1, the pick-up device 1 is freely rotated with respect to a head piece 12 in an open state and a rotation angle lock 2 which stops the pick-up device 1 at a predetermined angle position in a close state. The pick-up device 1 can freely be rotated and stopped with respect to the head piece 12 manually and easily without requiring an additional tool.
