<p>PROBLEM TO BE SOLVED: To provide a valve drive device capable of ensuring longer lives of members and efficiently transmitting a drive force of an actuator to a valve.SOLUTION: A first rod 65 has one end connected to a first drive lever shaft 43 relatively rotatably and the other end connected to a first valve lever shaft 612 relatively rotatably. A second rod 66 has one end connected to a second drive lever shaft 53 relatively rotatably and the other end connected to a second valve lever shaft 622 relatively rotatably. A first specific shape part 71 is formed at a position away from a shaft of an output shaft 37 of the first drive lever 40 at a predetermined distance. A second specific shape part 72 is formed on the second drive lever 50 so as to be able to abut on the first specific shape part 71. A spring 81 is provided between the first drive lever 40 and the second drive lever 50 and urges the first drive lever 40 and the second drive lever 50 in a direction in which the first specific shape part 71 and the second specific shape part 72 are closer to each other.</p> |
