取付けるに、羽根車軸心部に連設されたボス部と
上記軸端部とを両者の一部螺合構造を伴い相互嵌
合して抜止めすると共に、ボス部内周面と軸端部
外周面との間に、上記ポンプ軸の軸端部よりも他
端側寄り位置において套嵌されたスリーブの軸方
向推力を受けて楔効果的に両面を摩擦締結する摩

根車とポンプ軸との取付け構造。 To removably attach the pump impeller to the shaft end of the pump shaft, the boss part connected to the impeller shaft center and the shaft end are fitted together with a partially threaded structure, and then removed. At the same time, a wedge is formed between the inner circumferential surface of the boss portion and the outer circumferential surface of the shaft end by receiving the axial thrust of the sleeve fitted at a position closer to the other end than the shaft end of the pump shaft. A mounting structure for a pump impeller and a pump shaft, in which a friction fastening means for frictionally fastening both surfaces is interposed, and an axial thrust applying means for the friction fastening means is provided on the rear end side of the sleeve.
