PURPOSE:To facilitate connecting work by providing a turning member of connecting both couplings in a condition that a fitting part of a male coupling is fitted to a fitting hole of a female coupling, and providing a restricting cylinder of internal peripheral surface shape, which can be fitted to an external peripheral surface shape of the turning member, so as to hold a connecting position of the coupling. CONSTITUTION:A tapered fitting part 33 of a male coupling 30 is fitted into a tapered fitting hole 25 of a female coupling 20. As a result, centering of fellow shafts 11, 12 can be facilitated. Next, each lever 40 is turned about a turning shaft 29 and moved to a connecting position from a disconnecting position, to fit a protruding part 43 of the lever into a recessed groove 36 in a side of the male coupling 30. Thereafter, a groove 51 of a sleeve 50 is fitted from upward to the outside of the lever 40, and by mating this sleeve 50 with upper/lower ends of the lever 40, turning of each lever 40 is restricted, thus to hold engaging the protruding part 43 of each lever 40 with the recessed groove 36 of the male coupling 30. In this way, both the couplings 20, 30 are completely connected through the lever 40. |
