PROBLEM TO BE SOLVED: To provide a synchronization device of a throttle valve capable of always properly keeping synchronization of mutual adjacent throttle valves, by preventing sticking of dust to a synchronization bolt and a set spring.SOLUTION: In this synchronization device of the throttle valve, a first transmission wall 23 is formed on a first lever 21 fixed to one valve stem, a second transmission wall 24 and a spring seat wall 25 mutually opposed by placing the first transmission wall in-between are formed on a second lever 22 fixed to the other valve stem, the synchronization bolt 26 abutting on the first transmission wall 23 is threadably attached to the second transmission wall, and the set spring 27 is contractively arranged between the first transmission wall 23 and the spring seat wall 25. A synchronization box 33 for storing the first transmission wall and the set spring by opening one side surface, is constituted of the second transmission wall 24 and the spring seat wall 25, an outside connecting wall 30 for connecting mutual outer end parts of these, an inside connecting wall 31 for connecting mutual inner end parts of these and a sidewall 32 for connecting these, and a cover wall 34 for covering its opening surface is continuously arranged on the first transmission wall 23. |
