PURPOSE: To effectively transport a torque by arranging a bent part which partially divides a side end of orifice in at least two radial fingers. CONSTITUTION: The slits 103 are radially arranged in the diaphragm 100, divided fingers are thus formed and the center becomes a seat. The ends of the slits 103 are connected to orifices 104, these orifices 104 are circumferentially arranged alternating with the root part 118 of the finger 102. The part 105 being side wall 107 of the orifice 104 in the root part of at least two fingers 102 of the diaphragm 100 is bent. The bent part 105 is different from a traditional one as it is arranged adjacent to the root part 118 of the finger. This constitution results in reduction of sag-down of the fingers 102. Therefore, the fingers are stiffened, no stroke that loses force occurs and a torque is effectively transported. |
