A structure of a transfer mechanism is supported by a bearing (15) attached to a disc (10) of a rotary table (1), connects between driven shafts (20) extending in a direction parallel to a rotation shaft (11) and a driving shaft (30) which rotates and drives the rotation shaft (11), and transfers rotation power from the driving shaft (30) to the driven shafts (20). Rollers (31) that turn around a radially extending shaft are arranged at intervals on an outer periphery of one of the driven shafts (20) and the driving shaft (30) in a circumferential direction, and at least one radially extending pins (23) are provided on an outer periphery of the other of the driven shafts (20) and the driving shaft (30), and the pins (23) enter among the rollers (31) arranged adjacent to one another in the circumferential direction in a state in which the driven shafts (20) and the driving shaft (30) are connected.
