ABSTRACT:
A pinion clutch for a starter is constituted such that a spline tube having first and second helical splines on the inner and outer surfaces thereof respectively is disposed on a drive shaft, the inner surface of the spline tube is engaged to the drive shaft by the first helical spline, while the outer surface of the spline tube is engaged to a clutch-outer by the second helical spline, and rollers are disposed between a clutch-inner which is integrally formed with a pinion and the clutch-outer so that a one-way clutch function is realized. The pinion clutch comprises a meshing spring and an impact torque absorbing spring urging the spline tube and the clutch-outer in a direction in which the spline tube and the clutch-outer move away from each other are in series disposed between the spline tube and the clutch-outer. The meshing spring and the impact torque absorbing spring have individual spring constants.
