ある。 Figures 1 to 4 show an embodiment of the present invention, with Figure 1 being a partial plan view showing the state when crimped, and Figure 2 being a partial plan view showing the state in which the mounting piece is inserted into the mounting groove. Fig. 3 is an exploded perspective view of the impeller, Fig. 4 is a perspective view of the impeller, Fig. 5 is a view equivalent to Fig. 1 illustrated for comparison, and Figs. 6 and 7 are conventional They are a diagram corresponding to FIG. 3 and a diagram corresponding to FIG. 1, respectively, showing examples. In the figure, 11 and 12 are end plates, 13 and 14 are mounting grooves, 15 and 16 are protrusions, 17 is a wing piece, 18 and 19 are mounting pieces, 22 is a caulking roller, and 23 is an impeller.

Claims

[Scope of utility model registration request]

A wing piece is fixed to an end plate, and the end plate has a mounting groove that is open at the outer periphery and extends from the outer periphery toward the center, and a length of the mounting groove is formed at the end of the wing piece. a mounting piece that protrudes with a width smaller than that of the mounting groove, is inserted into the mounting groove in a state that it is pushed into the inner part, and is fixed to the end plate by caulking the open side edge of the mounting groove; An impeller comprising: a protrusion formed on an open side edge of the attachment groove so as to protrude inward of the attachment groove and abutting one end in the width direction of the attachment piece.
