The purpose of the present invention is to provide a disc spring (1) having a protruding section (3) with a load characteristic that does not easily vary in comparison to a disc spring (1) without a protruding section (3). This disc spring (1) is provided with: a main body (2) that has a conical ring shape and has, in a radial-direction end section (20), a contact portion (200) which contacts a counter member (92); and a protruding section (3) that protrudes from the radial-direction end section (20), has a plate thickness (t2) less than that of the main body (2), and does not contact the counter member (92). The protruding section (3) is uplifted from the counter member (92). A gap is secured between the protruding section (3) and the counter member (92). |
