摘要: A joining link, a strut, and first and second expansion levers constitute an expansion and contraction device. At the time of the braking, the proximal end portion of both of the expansion levers are mutually pressed from the opposite sides by first and second pressing members constituting a driving device. The reaction due to the braking is offset by the joining link portion, whereby a large force is not applied to the back plate or the like.

摘要: Disclosed is a drum brake device in which during a service brake application, a pair of brake shoes operates in a leading/trailing mode, and during a parking brake application, a parking brake mechanism operates to cause the brake shoes to operate in the duo servo mode. A first lever, an equalizer and a second lever, which make up the parking brake mechanism, are all assembled onto one of the brake shoes. The second lever includes an input portion, a lever contact portion and an equalizer contact portion. The input portion receives a force from a parking lever. The lever contact portion applies a turning force to the first lever. The equalizer contact portion applies a turning force to the equalizer. The second lever, when it is turned, turns the first lever and then the equalizer.
