とを特徴とする工作機における揺動アーム装置。 In a machine tool equipped with a swinging arm that supports a spindle head, an arm holder that pivotally supports a drive shaft of the swinging arm has a groove portion that receives a connecting portion at the tail end of the swinging arm that is fitted to the drive shaft. A plurality of pistons are provided at intervals in the circumferential direction and are pressed against each groove wall surface by fluid pressure on both side surfaces of the connecting portion facing the groove wall surfaces on both axial sides of the groove portion. Features a swinging arm device for machine tools.
