Disc spring member

A disc spring member that is provided between a first pressed body and a second pressed body, which face each other in a first direction, in a state of pressing the first pressed body and the second pressed body in directions away from each other in the first direction, the disc spring member comprising:

• a first member;
• and
• a second member,
• wherein the second member increases in diameter from a side of the first pressed body to a side of the second pressed body in a state of being provided between the first pressed body and the second pressed body,
• a plurality of the first members are provided at intervals in a circumferential direction,
• the plurality of first members are connected via a connecting plate extending in the circumferential direction,
• the plurality of first members and the connecting plate are integrally formed of the same material,
• in a cross-sectional view taken along the first direction, the first member spans the second member in the first direction such that the first member or the connecting plate is located at least at a radially inner end portion of an outer peripheral surface, which faces radially outward, of the second member and a radially outer end portion of an inner peripheral surface, which faces radially inward, of the second member, and
• the second member presses the first pressed body via the first member or the connecting plate and presses the second pressed body via the first member or the connecting plate.
