Abstract: The spring member (1, 2, 3) includes a conductive plate (11) and a support plate (12), the conductive plate is formed of a material in which at least one of electrical conductivity and thermal conductivity thereof is higher than that of a material forming the support plate, the support plate is formed of the material having a higher Young's modulus than that of the material forming the conductive plate, two end portions of the conductive plate in a second direction (X) are provided with first contact portions (13) that contact a first pressed body (W1), an intermediate portion of the conductive plate in the second direction is provided with a second contact portion (14) that contacts a second pressed body (W2), the two end portions of the conductive plate in the second direction are engaged with two end portions of the support plate in the second direction, an intermediate portion of the support plate in the second direction is provided with a third contact portion (15) that contacts the second contact portion, and the second contact portion is sandwiched between the third contact portion and the second pressed body in a first direction (Z).

CPC classification number: F16F1/18

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.
