A starter is described for an internal combustion engine having a ring gear, the starter comprising: a starter motor having an armature shaft; a drive shaft extending in coaxial relation to the armature shaft, the drive shaft having a projection extending radially outwardly from an axial end of the drive shaft adjacent the armature shaft; a pinion in spline engagement with an outer periphery of the drive shaft and adapted to be in mesh with the ring gear of the internal combustion engine; a planetary gear type speed reducing mechanism comprising a sun gear formed on an outer periphery of an axial end portion of the armature shaft of the starter motor, Planetary gears rotatably mounted on the projection of the drive shaft so as to be in meshing engagement with the sun gear, and an internal gear disposed radially outwardly of the planetary gears so as to be in meshing engagement with the planetary gears. The planetary gear type speed reducing mechanism is operative to reduce the rotational speed of the armature shaft and transmit the rotation of the armature shaft to the drive shaft through the sun gear, the planetary gears and the internal gear; a center bracket comprising a cylindrical portion supported through a bearing by an outer periphery of one of the drive shaft and the armature shaft, and a disc-shaped portion extending radially outwardly from an axial end of the cylindrical portion; and a shock absorber unit.
