To improve an operational feeling.SOLUTION: A moderation surface 60 of a moderation feeling generation body 50 contacts to a tip part 13 of a switch motion body 12 that is rotated as a center of a rotational center O, and applies a moderation feeling by generating a reaction force against a rotation operation of the switch motion body 12. In a step of rotating the switch motion body 12 to a second angle from a first angle (a position P0), a region R1 to a position P6 (a second position) corresponding to a timing when a reaction force becomes zero from a position P4 (a first position) corresponding to the timing when the decline of the reaction force is started from a peak on a moderation surface 50 is formed in a projection curvature shape projected on the side of the rotational center O. Among a curvature radius of the region R1, the curvature radius of a part which contacts to the position P4 within the region R1 (position at a neighborhood of the position P4, including the position P4) is the maximum.SELECTED DRAWING: Figure 5
