Derailleur

摘要

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.

1. A derailleur comprising:
a base member configured to be attached to a bicycle frame; a movable member configured to be movable with respect to the base member between a retracted position and an extended position at which the movable member is farther from the base member than the retracted position; a link member configured to movably couple the movable member to the base member; an additional link member configured to movably couple the movable member to the base member, the additional link member being a separate member from the link member and the movable member; and a biasing mechanism 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 comprising:
a biasing member having a first end portion; andan intermediate member separately provided from the movable member, the link member, and the additional 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.
