Problems solved by technology

Therefore, as the rider steps on the pedals, the anti-rotation part of the outer part body will be repeatedly squeezed in the direction of rotation by the sprocket coupling part. In the outer part made of aluminum, either the spline of the anti-rotation part is deformed, or injury, fatigue, etc.
[0008] Especially in the multi-stage sprocket type outer part, for example, in the case of replacing a part of the sprocket with a new sprocket, since the sprocket must be axially slid from the outer part together with the outer sprocket, Take it off, it is difficult to operate in the deformed state of the anti-rotation part

Abstract

A rear hub has a hub shaft and a hub outer that is configured to be mounted in a freely rotatable manner to the hub shaft. The hub outer has an outer main body and an adapter. The outer main body is arranged on the radially inward side of a sprocket, and has a first rotation preventing section that engages with an engaging section of the sprocket in such a manner that the outer main body cannot rotate relative to the sprocket. The adapter is mounted in a freely rotatable manner on an adapter mounting section of the outer main body. The adapter includes a second rotation preventing section that engages with the engaging section of the sprocket in such a manner that the adapter cannot rotate relative to the sprocket.

Description

technical field [0001] The present invention relates to an outer part for a bicycle hub, in particular to an outer part for a bicycle hub which is rotatably mounted on a hub axle of a bicycle hub. Furthermore, the invention also relates to a hub having such an outer part. Background technique [0002] A bicycle generally has a frame constituting a frame of a vehicle body, and a rear hub of a rear wheel is connected to a rear end of the frame. The rear hub usually has a hub axle arranged at the center of rotation of the rear wheel, an outer member and a hub shell that are freely rotatable around the hub axle, and a unit that connects the outer member and the hub shell so that they can rotate relative to each other in only one direction. to the overrunning clutch. The hub shell is a cylindrical member to which the spokes of the rear wheel are connected on the outer periphery. The outer member is disposed adjacent to the hub shell in the axial direction, and is a cylindrical...
