PURPOSE:To ensure concentricity by providing a fitting hole and a setscrew on one shaft end of a shaft and a split ring on the other shaft end, and disposing a fastening member which is engaged with the setscrew to press two shafts in a shaft coupling. CONSTITUTION:A fitting hole 17 to which a shaft end of a shaft 6b is fitted is bored in the end portion of a shaft 6a of a pump shaft 6, and a setscrew 18 is threaded on the outer periphery of the shaft 6a. A split ring 20 is disposed on the outer periphery of the shaft 6b. The shafts 6a, 6b are coupled to each other by a fastening member 21, one side of which is engaged with the split ring 20, the other side thereof having a setscrew 22 engaged with the setscrew 18. Thus, the concentricity can be ensured simply. |
