PROBLEM TO BE SOLVED: To accurately direct a tool part, which is attached to a connection point, by providing a device for forcibly generating the predetermined angle of rotation between a part, which is provided with a lathe dog, and a part, which has a lathe dog housing groove. SOLUTION: A connection point is provided with a device 15 for forcibly generating the predetermined angle of rotation between a first part 3 and a second part 7. A pin 17 is projected so as to ride over a side block surface 23, and energized to a side surface 13 of a groove 9 so as to be pushed. The adjusting force thereby forcibly generates the predetermined angle of rotation of a first part 3 of the connection point 1 in relation to a second part 7 thereof. A left side block surface 17 of a lathe dog 5 opposite to the block surface 23 is pushed to a side surface 11 of the groove 9 by the adjusting force of the device 15. |
