PROBLEM TO BE SOLVED: To provide a clamp coupling for a shaft which can easily quickly couple shafts. SOLUTION: A shaft-inserted part 1 of this clamp coupling in which a shaft S is inserted is divided by a plurality of slits 11 extending in the axial direction such that it can be elastically contracted. On the outer peripheral surface of the tip of the shaft-inserted part 1, a tapered part 13 gradually expanding toward the tip is formed. A fastening ring 2 which presses the tapered part 13 to elastically contract the shaft-inserted part 1 when moved toward the tip of the shaft-inserted part 1 is fitted on the outer periphery of the shaft- inserted part 1. The fastening ring 2 is always elastically biased by a spring 3 toward the tip of the shaft-inserted part 1. |
