Human-powered vehicle components

Abstract

The purpose of this disclosure is to provide a component for a human-powered vehicle that contributes to design freedom. The human-powered vehicle component disclosed herein includes: an input shaft that receives human driving force and has an input center axis; a rotation ratio changing unit that transmits the rotational force of the input shaft; and a transmission unit that has a transmission input unit, a transmission output unit, and a transmission center axis different from the input center axis, and is configured to change the ratio of the rotational speed of the transmission output unit to the rotational speed of the transmission input unit, i.e., the transmission ratio; the rotation ratio changing unit includes an input rotating body connected to the input shaft and rotating about the input center axis, an output rotating body connected to the transmission unit and rotating about the transmission center axis, and a transmission rotating body that transmits the rotational force of the input rotating body to the output rotating body, and is configured to change the ratio of the rotational speed of the output rotating body to the rotational speed of the input rotating body; the transmission rotating body rotates about a transmission center axis different from both the input center axis and the transmission center axis.
