PROBLEM TO BE SOLVED: To provide a louver angle adjustment device in which a degree of freedom of a louver angle adjustment is increased to perform a smooth rotation and provide a mist generating device including this louver angle adjustment device.SOLUTION: A shaft fixing means is constituted by a spring part 40 formed by a coil part 42 wound by several times around a shaft part 39 of a louver 22, the first spring end part 43 and the second spring end part 44 formed at the end part, the first protrusion 45 and the second protrusion 46 abutted against the first spring end part 43 and the second spring end part 44 when the louver 22 stands still. When the louver 22 is rotated by the shaft fixing means, a shaft part 39 is rotated and a motion of the first spring end part 43 is restricted by the first protrusion 45, a diameter of the coil part 42 is gradually decreased to fasten the shaft part 39 and the shaft part 39 cannot be rotated with a specified force if the fastening force exceeds the maximum frictional force between the shaft part 39 and the coil part 42, so that it is possible to perform a smooth angular adjustment of the louver 22 and thus a degree of freedom in regard to the angle where the louver 22 can be fixed is increased and its convenient in use is improved.SELECTED DRAWING: Figure 5 |
