CONSTITUTION: A fixed shaft(610) is fixed to a structure. A fixed pneumatic transmitting block(630) is fixed to the fixed shaft. A plurality of pneumatic input ports(631) are installed around the fixed shaft in a circumferential direction. A rotary pneumatic transmitting block(640) is rotatably combined with the fixed shaft and is contacted with the fixed pneumatic transmitting block. A plurality of pneumatic output ports(641) are installed in the rotary pneumatic transmitting block. |
