To provide a ventilator for a vehicle capable of improving connecting strength of both ends of a link and to be hardly broken even in rough operation without requiring any special designing consideration.
The connecting strength on spherical parts on the both ends of the link 19 is improved as the spherical parts 13 on the both ends of the link 19 are held between round holes 12a, 17a of plate parts 12, 17 formed on an operation dial 15 and a lever 11 free to rotate freely. Additionally, it is hardly broken as the spherical part 13 comes off from between each of the plate parts 12, 17 when there is a large input due to rough operation of the operation dial 15. Moreover, it is simple in structure and easy to manufacture as a socket part 18 on the side of the operation dial 15 and a lever 11 as a "socket part" on the side of a shut valve 10 are formed of a pair of the plate parts 12, 17.
