<p>The seat rotation device (30) for a baby buggy has a rotation unit connected to the seat underside (20) and two insert pieces on two sides of the underside of the rotation unit in a positioning unit (40). The rotation unit has a disk (31) which has a multiplicity of top side through passages and two positioning bars (21) of the seat extend outwards through the through passages. A number of positioning holes are defined in a periphery of the disk and an angle of 90 degrees is defined between two adjoining positioning holes. A shaft extends outwards through a first central hole in the disk and a second central hole in a base, so that the disk can be rotatable around the shaft.</p> |
