る。As described above, the present invention allows the main body sheath (1) and the unit-side hose joint (2) to rotate relative to each other very smoothly via the ball (12), so that during one operation, the main body sheath side can be rotated in various ways. Even if the hose is at an angle, twisting of the hose group connected to the hose joint (2) is prevented and good operability is maintained.
また内部への注油にあっては、被筒（２ｂ）を案内溝（

部を経て頭部の軸受部へ送られ、これを潤滑する。Also, when lubricating the inside, insert the sleeve (2b) into the guide groove (
If it is rotated appropriately within the allowable range of 8), the oil filling hole (7) will open, so that oil can be easily filled through the oil filling hole (7). Since this lubrication hole (7) communicates with the drive air communication passage (6a), the air is sent to the bearing part of the head via the connection part and lubricates it.
以上−こよって本発明が冒頭に掲げた所期の目的を。Thus - the invention thus achieves the intended purpose set out at the outset.
