The invention relates to a wheelchair having side frames including tube sections having a tube-bend at the front bottom end of each in an area proximate to where a bearing housing is mounted. The bearing housing has an approximately vertical bearing bore for accommodating an upwardly directed axle pin of a steering fork for holding a caster. The bearing housing also has an adjustment device, which is integrated in the screw mounting, for adjusting the bearing housing with respect to the side frame in order to align the bearing bore perpendicular to the ground. The bearing housing is mounted to the tube-bend via a guide passage of a clamping shell, which is correspondingly curved and is open on one side. The clamping shell is fitted laterally to the tube-bend and, is displaceably guided and is fixable in the desired position by tightening at least one clamping screw.
