A rear derailleur with rotation resistance application function includes a base member, a link assembly, a movable member, and a chain guide, wherein the base member is mounted on a frame; the link assembly is flexibly connected between the base member and the movable member; and the chain guide is connected to the movable member via a rotation-with-resistance structure. The rotation-with-resistance structure includes a rotary shaft, a one-way bearing and a resistance application spring, wherein the rotary shaft is disposed on the movable member or the chain guide; the one-way bearing matched with the rotary shaft is correspondingly disposed on the chain guide or the movable member; and the rotary shaft forms an interference fit with an inner hole of the one-way bearing. The rear derailleur can effectively prevent a chain from coming off during bumping.
