Abstract
A spring member is provided between two pressed bodies facing each other in a first direction and includes base plates stacked in the first direction. Each base plate is provided with spring protrusions protruding toward either one pressed body of the two pressed bodies and pressing the two pressed bodies in directions such that the pressed bodies move away from each other in the first direction. Between two base plates adjacent to each other in the first direction, a base plate positioned closer to the one pressed body is provided with an insertion hole into which a spring protrusion of the other base plate is inserted in a state of penetrating therethrough in the first direction. Among portions in an along-plane direction along a plane orthogonal to the first direction provided with the spring protrusions, the spring constant of at least one portion is different from that of another portion.
