PURPOSE:To reduce a space in the periphery of a rear suspension device, which is required for wrench operation by fitting a wrench in wrench holes of each stage alternately to reliably shift a notch at a small rotating angle of the wrench. CONSTITUTION:Plural stages of wrench hole arrays 91, 92 are disposed on the peripheral surface of a spring sheet 8, and the wrench holes 91, 92 of the respective stages are arranged in such a manner as to shift from each other in the axial direction. The pitch between the wrench holes is set equal or smaller than the notch pitch between the notches 8a, 8b. This arrangement can reduce a space required for wrench operation. |
