Claims

[Scope of utility model registration request]

An impeller is attached to a drive shaft, and is fitted to the drive shaft from the front through a shaft communication hole provided in the impeller and open in the front and rear axial direction, and a shaft communication hole provided in the drive shaft. a stop portion for stopping the impeller at least in the fitting direction; a stop portion provided at the tip of the drive shaft located ahead of the stop portion and protruding forward from the shaft insertion hole;
An operating member is attached to the front surface of the impeller so as to be movable in the axial and radial directions, and the operating member is provided with an operating member that elastically overcomes the tip of the drive shaft by moving rearward in the axial direction. an engaging member that engages with a stop portion and is disengaged by movement in the radial direction away from the stop portion; and at least the stop portion that is provided between the engagement member and the impeller. An impeller mounting device comprising a spring that biases the engaging member radially toward the center of the drive shaft and simultaneously biases the engaging member forward in the axial direction when the engaging member is engaged with the member.
