Abstract:
The link mechanism 120 comprises: a rotation axis of a rotating body that is attached either to a first link member (rod 140) having a first hole (valve-side through-hole 141B) formed therein, or to a second link member (valve-side link plate 150B) having a second hole (pin hole 151B) formed therein; a valve-side spring member 170B disposed between the first link member and the second link member; and a valve-side joint pin 160B.
