Title:
DISC SPRING MEMBER
Document Type and Number:
WIPO Patent Application WO/2023/176721
Kind Code:
A1
Abstract:
In the present invention, a disc spring device comprises a first member and a second member. In a state of being disposed between a first pressed body and a second pressed body, the second member has a diameter that becomes increasingly larger from the first pressed body side toward the second pressed body side. In a cross-sectional view along a first direction, the first member straddles the second member in the first direction so as to be positioned at least both at a radially inner end of an outer circumferential surface of the second member that faces the radially outer side and at a radially outer end of an inner circumferential surface that faces the radially inner side. The second member presses the first pressed body via the first member, and presses the second pressed body via the first member.
