Abstract
A rotary knob includes: a wall member defining a mating hole in which a rotation shaft including a shaft portion whose outer circumferential surface has a flat surface extending parallel with an axis of the rotation shaft can be fitted; and an elastic piece formed in a strip shape and formed on an inner surface of the wall member so as to extend along an axis of the wall member. The elastic piece is in contact with the flat surface and elastically deformed when the rotation shaft is fitted in the mating hole. The elastic piece includes: opposite side portions fixed to the inner surface of the wall member; and a central portion in a widthwise direction perpendicular to the axis of the wall member. The elastic piece includes a convex surface constituted by the central portion which curves inward in a radial direction of the mating hole.
