PURPOSE:To prevent the breakage of the rotary shaft of a brushless motor in mounting of a polyhedron, and secure highly accurate installation. CONSTITUTION:A rotary polyhedron 5 is positioned by the engagement guide 6 made at the contact face of a flange 4, which supports a rotary polyhedron 5, with this rotary polyhedron 5. Moreover, this engagement guide 6 stores a corrugated washer being the installation adjusting member 7. The height control of the polyhedron 5 press-fit onto the rotary shaft 1 is performed with this installation adjusting member 7. The rotary polyhedron 5 is pressed and fixed onto the flange 4 at constant pressure through a press plate 8. Thus, the rotary polyhedron can be attached to the rotary shaft 1 without working excessive extractive force between the rotary shaft 1 and the flange 4 and accurately. |
