ブ。 A hollow shaft for attaching a small gear, which has an outer ring part of the free mechanism and a ball receiving part of the clutch mechanism, is fixed to the hub body and rotates integrally with the hollow receiving shaft which has a free mechanism receiving part and a ball holding hole of the clutch mechanism. The clutch ball, which is held by a hollow shaft integrated with the hub body, moves within the ball holding hole by a sleeve that slides on the central fixed shaft (rear shaft). The clutch ball receiving part of the gear mounting shaft is wedged in or released to allow switching between free and direct connection, and the slide sleeve is operated by a spring and a wire installed in the center hole in the fixed shaft. Free/direct connection switching hub for bicycles.
