SOLUTION: A ring chamber 49 having the axial length longer than the maxims moving distance of a driven shaft 5 is formed in a cylinder 46 and a communication path 50 penetrated in the diametrical direction of a spool rod 47 is communicated with the ring chamber 49 all the time even in moving of the spool rod 47. An oil through path from an oil path 55 for a support member 45 to an oil path 52 for a swivel arm 48 is not cut off so that cutting oil fed from an oil feed pipe 63 to a feed port 62 is fed to an oil hole of a tap 7 through a series of the oil through path from a stopper pin 39 to the tap 7.
