ABSTRACT:
At both of the upper and lower faces of flange section (24A) of rotation body (24) rotatably retained between lower case (21) and upper case (23) opposed to each other via inner case (22), inner concavo-convex section (25) and outer concavo-convex section (26) are provided at point-symmetric positions on concentric circles of an inner circumference-side circle and an outer circumference-side circle. Inner elastic contact projection (27C) and outer elastic contact projection (27D) of double ring-like click spring (27) respectively elastically contact inner concavo-convex section (25) and outer concavo-convex section (26) respectively corresponding to both of the upper and lower faces of flange section (24A), thereby providing a clear click feeling and a high click degree.
