PROBLEM TO BE SOLVED: To provide a clamp joint for a shaft capable of easily and quickly connecting the shaft in a single operation. SOLUTION: When a shaft 6 is inserted to the inside of an elastically contractible shaft insertion part 1, a collar 4 inserted to the inside of the shaft insertion part 1 is moved to its rear end side, a ball 5 held in the shaft insertion part 1 is advanced to its inward and engaged with a V groove 61 of the shaft 6. Simultaneously with this operation, a fastening ring 2 with its movement regulated to a tip end side of the shaft insertion part 1 by the ball 5 is automatically moved to the tip end side of the shaft insertion part 1 by energizing force of a first spring 31, and the shaft insertion part 1 is elastically contracted. |
