A derailleur comprises a base member, a movable member, a link member, and a biasing mechanism. The movable member is configured to be movable with respect to the base member between a retracted position and an extended position. The link member is configured to movably couple the movable member to the base member. The biasing mechanism is configured to bias the link member such that the movable member is disposed at one of the retracted position and the extended position. The biasing mechanism comprises a biasing member and an intermediate member. The biasing member has a first end portion. The intermediate member is separately provided from the movable member and the link member so as to transmit biasing force of the biasing member from the first end portion to one of the movable member and the link member through the intermediate member.
