A divided type aligning rolling bearing comprises a spherical groove of a lower bearing housing for slidably receiving an outer peripheral surface in a spherical shape of an outer ring lower member. A dowel pin is provided on the outer peripheral surface of the outer ring lower member and fitted in a recess provided on the bottom of the spherical groove of the lower bearing housing so as to have a backlash. The range of the backlash is an aligning range. The outer ring lower member is rotated around the dowel pin, thereby causing both ends of the outer ring lower member to escape from the spherical groove. In order to allow the escape, the lower bearing housing is in a non-rib shape. The outer ring lower member is brought into a detachable state by changing the posture thereof in a stable state.
