る、自転車用ユニツトハブ。[Claims for Utility Model Registration] On the outer periphery of a bearing sleeve that is integrally fixed to the right end of the hub body, there are inner and outer parts located apart in the axial direction, consisting of an inner first bearing part and an outer second bearing part. The gear support is rotatably supported in only one direction through a pair of bearing parts and a ratchet mechanism located in the middle of these bearing parts, and the bearing sleeve is connected to the hub shaft through a third bearing part. In the bicycle unit hub rotatably supported by the first bearing, the first bearing has a first spherical bearing surface formed in the form of a groove having a substantially semicircular cross section by hollowing out the outer periphery of the bearing sleeve radially inward. , consisting of a second ball receiving surface formed on the inner periphery of the inner cylindrical body of the gear support, and a steel ball rotatably interposed between the first and second ball receiving surfaces, The second bearing part is connected to a third ball receiving surface on the outer periphery of a screw cap screwed to the outer periphery of the tip end of the bearing sleeve, and a fourth ball receiving surface formed on the inner periphery of the outer cylinder body of the gear support. and a steel ball that is rotatably interposed between the third and fourth ball bearing surfaces, and the third bearing part is integrally formed on the inner periphery of the bearing tube. a sixth ball receiving surface on the outer periphery of a ball pusher screwed into the hub axle, and a steel ball that is rotatably interposed between these fifth and sixth ball receiving surfaces, and further comprises: A unit hub for a bicycle, characterized in that a dustproof wall rising toward the inner end of the gear support is attached to the outer periphery of the bearing tube adjacent to the inner side of the first ball receiving surface.
