PURPOSE:To facilitate detachment and attachment of a coupling by inserting an intermediate flange with a faucet male portion in a concave portion formed on the end surface of a flange body in such a manner as to slide axially, and moving the intermediate flange by operating an adjust bolt threaded on the flange body. CONSTITUTION:A concave portion 18 is formed on the end surface 17 of a flange body 11 fixed to a shaft 12 through a key 13, and an intermediate flange 19 having a faucet male portion 21 and a concave groove 22 at both side end surfaces thereof is inserted in the concave portion 18. The axial position of the intermediate flange 19 is adjusted by operating an intermediate flange adjust bolt 26. A link coupling 15 having a faucet female portion 14 at the end surface thereof, to which three rotary plates 34 are coupled by links 33, 35, is fixed to the flange body 11 by a fixing bolt 16. The coupling 15 is detached by detaching the bolt and turning the adjust bolt 26 to draw the intermediate flange 19 into the concave portion 18. |
