The pressing structure includes a spring member including: a base portion formed of a single strip-like member and having a curved principal surface; two extended portions extending respectively from end portions of the base portion and curved in a form inverse of a curving form of the base portion; and two bent portions extending respectively from end portions of the two extended portions, the end portions being at sides opposite to sides connected to the base portion, the two bent portions being curved in a form inverse of the curving form of the extended portions; and the maximum thickness of the extended portions and bent portions is smaller than the maximum thickness of the base portion.
