Abstract
A valve device for an exhaust flow passage includes a toggle mechanism, in which a support-side link member and a valve-side link member form a first stopper mechanism and a second stopper mechanism. The first stopper mechanism is configured to limit a link angle formed by the support-side link member and the valve-side link member by abutment of a first support-side stopper portion formed in the support-side link member and a first valve-side stopper portion formed in the valve-side link member against each other. The second stopper mechanism is configured to limit the link angle by abutment of a second support-side stopper portion formed in the support-side link member and a second valve-side stopper portion formed in the valve-side link member.
