An inclining action device, comprising: a moving member; a fixing frame elastically supporting the moving member; a driving force applying unit configured to apply driving force to cause the moving member to repeatedly perform an inclination action, wherein the inclination action changes an inclination angle of the moving member with respect to the fixing frame from the inclination angle at a start arrangement of the moving member to the inclination angle at an end arrangement of the moving member; a driving signal generating unit configured to generate a driving signal to drive the driving force applying unit; an inclination angle information sensing unit configured to sense the inclination angle of the moving member to obtain inclination angle information indicating the sensed inclination angle of the moving member that changes over time in one inclination action; and an adjustment processing unit configured to correct the driving signal generated by the driving signal generating unit so as to suppress fluctuations in the sensed inclination angle with respect to a target inclination angle in one inclination action; wherein the driving force applying unit employs at least two driving elements to apply the driving force to repeatedly perform the inclining action on the moving member, the driving signal generating unit is configured to generate a driving signal independently for each of the at least two driving elements, characterised in that: the adjustment processing unit is further configured to change a phase difference between the driving signals generated by the driving signal generating unit. a moving member; a fixing frame elastically supporting the moving member; a driving force applying unit configured to apply driving force to cause the moving member to repeatedly perform an inclination action, wherein the inclination action changes an inclination angle of the moving member with respect to the fixing frame from the inclination angle at a start arrangement of the moving member to the inclination angle at an end arrangement of the moving member; a driving signal generating unit configured to generate a driving signal to drive the driving force applying unit; an inclination angle information sensing unit configured to sense the inclination angle of the moving member to obtain inclination angle information indicating the sensed inclination angle of the moving member that changes over time in one inclination action; and an adjustment processing unit configured to correct the driving signal generated by the driving signal generating unit so as to suppress fluctuations in the sensed inclination angle with respect to a target inclination angle in one inclination action; wherein the driving force applying unit employs at least two driving elements to apply the driving force to repeatedly perform the inclining action on the moving member, the driving signal generating unit is configured to generate a driving signal independently for each of the at least two driving elements, characterised in that: the adjustment processing unit is further configured to change a phase difference between the driving signals generated by the driving signal generating unit.
