Zusammenfassung:An operation input device excellent in an operation feeling, capable of smooth rotation and having less occurrence of dust includes a base 10; a support shaft 30 elastically implanted to and supported by the base 10 in such a manner as to be capable of tilting; a printed substrate 20 equipped on an upper surface thereof with a plurality of bush button switches 34a to 34d and Hall IC 24a and 24b mounted thereto, and put on and integrated with the base 10; an operation plate 40 arranged on the printed substrate 20; and an operation dial 50 having a ring-like magnet 55 having N poles and S poles alternately arranged on a lower surface thereof and supported to an upper end portion of the support shaft 30 in such a manner as to be capable of rotation. The Hall IC 24a and 24b detect the change of a magnetic flux of the ring-like magnet 55 and a rotating direction when the operation dial 50 is rotated, and the push button switches 34a to 34d are driven through the operation plate 40 when an outer peripheral edge portion of the operation dial 50 is pushed down.
