And an auxiliary plate spring 118 coupled to the fixing body 110 and contacting each other when the first plate spring 112 returns after elastic deformation to generate friction and impact sounds. The second leaf spring 113 is coupled to the fixed body 110 at a position opposite to the leaf spring 112 and has a protrusion 113a formed to elastically contact the unevenness 122.

Reference numeral 130 is coupled to the fixing body 110 as a cover plate to prevent the departure of the rotating body 120. Reference numerals 116 and 117 denote coupling grooves to which the first leaf spring 112, the auxiliary leaf spring 118, and the second leaf spring 113 are coupled.
